This is new /sec/, the security board. The intent is that this board will be used to discuss means of securing electronics and other machinery. Discussion of securing other types of objects, such as houses, safes, and privacy is very welcomed. Discussion of offensive means, cracking tools, and secret documents is permitted and also very welcomed.

Do remember to be smart when discussing potentially illegal activities.

Relevancy is considered very important in this board. It is expected that every image and file will be strictly relevant to security of this sort.

Do not start a thread designed to collect information concerning the lives, preferences, or other potentially sensitive information of users on this board.

Hide loudly; live creatively; crack happily. Secure well; fear naught.

So we just had a discussion on "Simple questions thread" that I think deserves it's only thread.

The discussion is about virtualization vs sandboxing. I'll post the comments bellow and you can contribute to it.

Capsicum is like kicking dead whales down the beach however, Pledge is the only thing that is being implemented on large scale.
There also is Seccomp for Linux but it isn't being used on large scale few applications use seccomp where Pledge is being used in the entire base already.
I think only OpenBSD does virtualization right with vmm/vmd with Pledge?
What i miss on OpenBSD is a RBAC like grsecurity has.
Anyway i don't think Xen is the right way but OpenBSD can indeed be improved here and there.
Just a reminder that most applications aren't built with security in mind so there is very little priv seperation, the only ones actually doing it are OpenBSD applications ( OpenSSH, OpenSMTP, ect )

Sounds nice in an ideal world where everyone can run the Muen seperation kernel, but in the real world we have linux which is a big security vulnerability, and windows which is an even bigger one.

>>127
>big = insecure

many short, easily-understood programs are actually very vulnerable, and many giant projects are airtight. What matters is how well those are designed and maintained, not how tiny they are.

I encourage everyone here to look into genode, which makes sandboxing and application seperation a core part of the OS architecture. I firmly believe it's the future of OS design.

While looks pretty complex to fix this on the political side, in technical side looks more promising with refine from some old projects like I2P and Tor.

The GUI says I have no connections, the terminal gets no results from searching anything. No documentation to get help from online.

Though once I can get the thing working, I'm absolutely happy to help flood it with content. Will look out for GNUnet threads here. Though I wonder if GNUnet will actually get a major release, since it's got GNU in the name...

I thought GNUnet was a single program, not a suite of protocols. If it's possible to develop a "www" like browser for GNUnet, I can see it competing with I2P+IPFS (which isn't even in existence yet).

>>258
That's a benefit to I2P, multiple router software. Not sure if IPFS has anything like that though.

But the other poster said that GNUnet is a suite of protocols, so if it's anything like I2P, people can write new routers.

i2p is more prone to traffic analysis, more hops isn't better and everyone using different browser setups make you stand out even more.

For the most part, the threat to a regular user will come through the either the web browser, or email.

Keep your browser up to date. Use an ad blocker (ublock/umatrix), specifically umatrix has some nice features. Privacy badger, HTTPS everywhere etc..

Keep your email client updated. Don't click on strange emails, don't click on every link you see. Do not even preview strange emails. Make sure your client has a feature that stops this behavior.

Install EMET, configure it to cover your applications and raise the protections to the maximum.

Do not use an admin account for every day tasks.

Modify your local group policy, a good starting point is https://github.com/iadgov/Secure-Host-Baseline , do not just apply it because it's fairly restrictive, modify and apply it to your needs.

Checking the STIG for Windows 10 is also a good place to look: http://iase.disa.mil/stigs/os/windows/Pages/win10.aspx

Set Windows firewall to deny everything that is not needed. Enable firewall logging and increase the size of the log. Go to your interface settings and disable whatever you don't use, same goes for any services.

Increase the max sizes of your event logs.


This is off the top of my head

Seems to me that physical security is just as important as digital security.

Personally, I've never picked a lock, but I'm considering learning. Watching some videos of experts has made me much more conscious of my choice of lock.

On a somewhat unrelated note, this is the setup for a server room at my uni. I kinda want to go in there and poke around, but I don't know what these boxes do. The lock itself seems pretty flimsy, once I learn I could probably break it. I'm more worried about security measures that I don't know about.

Need some advice.
I'm thinking about buy an old (<2005) IBM thinkpad and do it as my HTTP/SMTP server for my personal website and mail. I'm doing it and not paying for a VPS because I could have the control of all the functions my self.
So, my problem is, I can do most of it without wasting money on some service, except that I would need a dynamic dns since my IP wouldn't be static (too expensive on my country). My question is: there's any way I can run a dynamic dns server myself, from the same dynamic IP? If yes, could I do it on the same machine?

I think it should be simple, since the dynamic dns server would just: grepping the actual IP > sending and updating to the domain name network. But I couldn't find this information at all.

That way I could host my server without waste any unnecessary money. The OS, http and smtp server would be free software. The domain could be from freenom. The TLS cert can be from Let's Encrypt. The static html could be something fancy from html5up.net.

Let's say I want to share an image with someone online, but I don't want them to have the ability to plug the file into google's reverse image search, because the source hosting the image(which I have no control of in this hypothetical scenario) contains personal information I'm not interested in sharing.

Obviously, there are ways to distort or otherwise change an image far enough that the algorithm of any reverse image engine can't associate it with the original host, but exactly how severely do I need to change the image to keep it from leaving a trail of bread crumbs back to a sensitive source?

Obviously metadata would need to be wiped, but I don't know how much visual distortion would be necessary. Cropping the image? Slightly changing the colors in an image editor? stretching it by a few pixels? Or are we talking a more blunt method, like adding harsh noise, or some kind of serious image warping?

Feel free to discuss the nuances and advantages of your preferred architectures and assemblers, along with all else relevant.

So, to get us started on messing with efficient machine code fragments, I give you this arbitrary length integer addition routine written in MIPS III (R4000):

nadd:    lw $6, 0($3)
lw $7, 0($4)
addu $5,$6,$7
sw $5, 0($4)
srl $5,$5,32
addiu $3,$3, 4
addiu $4,$4, 4
addiu $2,$2,-1
bne $0,$2, nadd
jr $31

Arbitrary length numbers are represented as vectors segmented into thirty two bit sections, ascending, the number of which is the length; one number is passed in register three and the destination and second summand is in register four; the length of the shorter number is in register two and must not be zero; registers six and seven are clobbered; register five is clobbered and holds a single bit if overflow occured; register thirty one holds the destination once the routine is finished. All but register thirty one can easily be changed.

I read in a thirty two bit word from each number, add it using bit thirty three as a carry flag, store this result in the destination location, then shift the carry flag into bit 1 and repeat until the addition is done.

I have actual MIPS hardware that I could test this with, but testing machine code routines is so frustrating on UNIX that I've merely given this a few glances over. I don't think there are any flaws, but I could be wrong.

Regardless, feel free to improve on this and point out any mistakes I may have made.

daddu $5,$6,$7
sw $5,0($4)
addiu $3,$3, 4
dsrl $5,$5,31
addiu $4,$4, 4
dsrl $5,$5, 1
addiu $2,$2,-1
bnezc $2, nadd
jr $31
add $0,$0,$0
I should really give myself a decent testing environment for these routines.

This is tangential to your post, but I found it worth posting.
>By my understanding, microcode is like a translation layer that the manufacturer uses to fix bugs in the architecture. Microcode reroutes around bugs burned into the silicone you will supposedly run into instability issues on these modern CPUs.
Microcode is the lower level operations the machine language is built from. On most modern processors, it's used for bug fixes and whatnot, but older architectures allowed people to write their own microcode and switch between them for different programs.

So, as an example, a language implementation would be capable of making the CPU directly suit its needs. Doesn't that seem powerful? If you needed an instruction to behave atomically, you could add that. If you wanted very high level instructions, you could add them.

...how hardened do you mean? The big distros (with one exception) are pretty good for desktop "I want to avoid malware while browsing" use cases. You can, of course, go a lot further with stuff like grsec if you want to, and it may pay to if you're running a server. But if you're running a server your first area of attention should be the configuration of the service you're setting up on top of the OS. And for a desktop or server the best thing you can do is to apply updates promptly, before worrying about kernel patches, MAC, etc.

Ok, I'm moving into a uni dorm within the month, and was looking at the network policy. It seems to be pretty strict. Not allowing your own routers/switches, banning the use of p2p software entirely, and even has a point that states being anonymous at all is not allowed. Infringement in any of these points and more result in disconnection and being sent to student conduct. What would you do /sec/? I don't think I can get through without use of private trackers, and knowing that everything that I do on the network will be visible to the school staff will gnaw on my sanity and probably alter my usage of the network.

There's a chance the uni might have their firewall filter VPN traffic. But that's not to say VPN wouldn't work. I had one set up on my home desktop a long time ago when I was in middle school and use it to watch YouTube poops in class. But I worked at the university I attended in their IT and found those kinds of things to be much more restricted. SSH is normally open for the computer science students at least.

Do you tell friends/family/people on the street about using Signal/ChatSecure/Tox or Tor, etc.? How successful have you been? A few people are grateful for the information and change habits, but most people have a sort of knee-jerk response when I talk to them about using software that protects my privacy, they seem to prefer ignorance to actually being aware of what is going on in the world, as far as dragnet surveillance goes. I mean, they know it happens but they prefer to just act as if everything's okay. Problems don't go away when you ignore them but a lot of people function as if that's the case.

I often get the impression that the majority of cybersecurity problems arise from the immense knowledge gap between people who genuinely understand the issue and the general public. I don't mean only the technical intricacies---which are understandably outside the realm of public knowledge---but also the broader, "obvious" concepts, like what constitutes a security breach. Then there's the press who, in a race to see who can get the more click-baity headline, will publish things which are misleading at best or totally fabricated at worst. This kind of sensationalism only expands this gap and, in my view, is making the general discipline of cybersecurity more difficult. The media's recent characterization of the recent election as having been "hacked" is one of the more egregious examples of this behavior.

An election has two parts. In the first part, votes are cast. In the second part, the votes are counted. This is an essential point, because if you do not understand that, then nothing that will follow can make sense to you.

Headlines that read some formulation of "Russia Hacked the US Election" are, to put it bluntly, wrong. They are fantastically wrong. It may be the case that bad actors intended to influence voters to cast their votes in a particular way. However, the continual repeated assertion that the election was "hacked" has given a large percentage of the voting population the impression that the casting or counting of ballots was affected. No credible source has made this assertion. Even if for the sake of argument it were the case that certain districts were hacked, many states do not use machines connected to the Internet, so flipping the election on a national scale would likely not be possible. Yet somehow, that has become a part of the national zeitgeist.

I am probably just ranting. I guess my larger question is, "How do you talk about this subject with people who are fundamentally clueless?" Furthermore, "How do you *unteach* someone who has accepted as fact an incorrect premise?"

>Anyway the whole thing about Russia hacking the election is way overblown. From all the information I've gathered, what Russia did was psychological operations on the American public in order to get them more on the side of Trump. If you read the emails, you would know that the DNC was running their own psychological operations on the American public as well in order to turn them more towards Clinton (Change the Record comes to mind). Not only that, but psychological operations aren't anything new, and the USA, Russia, China, and countless other countries have been running psychological operations in multiple countries for decades now. Some examples that come to mind is America dropping flyers in the Middle East (yes this is still a psychological operation), Russia in Eastern Europe, China going back to Sun Tzu, etc. You will find countless examples if you just google "psychological operations"

I'd agree with that, but I also think that Russia running psyops on our political processes is something about which we should get upset. I think it's different from the DNC running their campaign because the DNC is a group within this country that openly nominates a candidate. I would think that the middle Eastern countries to which the US does similar things would get angry in exact proportion to how much they think that they can do about it.

i'm currently thinking about how to set up an offsite backup in a secure manner. there are essentially two options i'm considering:
* encfs reverse filesystem, then rsync the encrypted files to offsite
* luks encrypted offsite storage, rsync the unencrypted files (still over a secure channel obviously)

my goal is to prevent anyone except me to view my files.

encfs:
+ files are encrypted before they leave the onsite location
+ i've used it successfully before and know how it works
- encfs has security issues if an attacker has repeated access to encrypted files
- encryption on a per-file level
- makes incremental updates difficult or impossible (?)

luks:
+ solid encryption (?)
+ encryption below filesystem level
- needs password entry over network on each boot (so no fully automated boot possible)
- files are only encrypted at offsite location (they are in the clear in offsite memory or with offsite OS access)

notes:
* I don't need to encrypt the root partition of the offsite server, encrypting the raid disks is enough
* offsite server has usb port inside case for an usb key boot partition (maybe needed for luks)
* offsite server has case-open detection switch ("tamper switch")
* I can't inspect the server on a regular basis, but I can do so occasionally (every 2-3 months) or when I suspect something is wrong, or when a harddisk fails

attacker model: "incompetent hardware access"
* attacker can do everything on the network, but i'm planning to use ssh or vpn or something anyway
* attacker has hardware access since it's offsite
* attacker has access to harddisks I throw away when they fail
* attacker can shutdown/disconnect server
* attacker cannot open case without shutting down server (tamper switch)
* attacker cannot disconnect server power without shutting down server (tamper detection)
* attacker cannot disconnect/remove harddisk while server is running without triggering a warning (either because of network disconnect or because of raid degradation)

encfs additional drawbacks on attacker model:
* attacker does not repeatedly read out harddisk contents and can determine file contents via encfs shortcomings (one-hit attacker only)

luks additional drawbacks on attacker model:
* attacker is not byzantine, as in he would not cut open the side of the server and access the memory or hardware bus from there while server is running.

Can you recommend one setup over another? Which one makes more sense? Is there some problem with either setup i haven't taken into account? Is the attacker model realistic? Anything i should change? Something else than rsync?

And, most important to me: How have you set up your offsite backups?

>duplicity
does it support synchronizing filesystems, without versioning or increments? as in, just have the same data (plus/minus encryption) on two servers?

The problem is that incremental takes up same-or-more space than just a duplicate which takes up same space. Which would create the need for more diskspace on the offsite storage than on the onsite storage, and it is difficult to tell in advance how much (as in, at harddisk-buying time).

The Human Trafficking Prevention Act is a piece of model legislation that is currently being advanced in several states. It would set up an opt-in filter for obscene content on the internet. The definitions for pornography in the USA are vague enough that such a law could easily be abused.

The following is an excerpt from the FAQ on their website (http://humantraffickingpreventionact.com/):
"Furthermore, the total prohibition against any form of government regulation is completely unrealistic and would create a state of nature. Consider this: a fish on the grass is not free. It is only when the fish is confined to water that it can swim lightening fast, thrive, and even breath. The same is true with humans. Mankind does not flourish best when child pornography,prostitution hubs, and obscenity are all one click away or unavoidable. Without “truth,” there is no “freedom.” “Freedom” comes from the “truth.” “Freedom” is not the “presence of restrictions” nor the “absence of restrictions.” “Freedom” is the presence of the “right restrictions,” the set of restrictions that objectively fits the givenness of our nature, the truth about “the way we are,” and the truth about “the way things are.” The set of restrictions that promote the most amount of peace, intimacy, reconciliation, healing, and forgiveness, in order to advance human flourishing to the maximized capacity are the set of restrictions that the state and federal legislature should adopt."

The authors of the model legislation are playing a bizarre sophistic game where they define freedom to mean "whatever we think is best for you." If that isn't enough to get you worked up enough to call your state representative, I don't know what is.

This is some serious fuarrrking newspeak. Do they actually say why being able to access obscene material restricts freedom?

Greetings Lainons.

We already know that Linux distros are more secure than Windows (in regards to unauthorized intrusion, NSA and spying, and general privacy). This thread does NOT debate this.

However, how can we take steps to secure the privacy of Windows? Namely Windows 10? What are some suits and programs that help protect privacy and security within Windows?

We already know about the backdoors (through fuarrrking updates no-less) and that Windows is fundamentally insecure anyway, but what are some things to help protect it more anyway?

I'm so on the fence about setting up my own mail server, it would be a good exercise for me and a good learning curve, but I shy away for most of the reasons listed - also downtime, sys fails and backups - its probably gonna be far better for my sanity if i just go with proton mail for my needs. (work and play) - I feel i would only be asking for yet another computing problem to walk into my life, at exactly the time I won't be wanting it :)

I am so conservative with my setups now days, I just want 100% reliability - lots of backups, no over-clocking, server grade MBs, ECC ram, RAID 10 or 6 only, only essential (but very comprehensive) software installed, play is of course done only on VMs.
I still get downtime and have moments when having 2 near mirrored HW workstation setups (as well as mirrored servers) has been a total blessing!

Majority of ISPs block the required ports for hosting your own e-mail server.
There are many workarounds however, such as using a VPS, VPN or redirect services.

This is the main problem people encounter when hosting their own mail server and probably the main reason most people don't do it, because it'll cost you money (even if it's only $5 it's still a bummer) and due to it's more public nature, there are more security risks involved.

Good morning, Lain. I fuarked up. I registered a .us domain for a novelty domain name, but I forgot that .us domains cannot be bought with WhoisGuard, so now my full name and address are openly available in that domain's Whois record. This domain has been hosting a site with a steady supply of visitors for a few months. I'm thinking about migrating to a different domain and letting the old domain redirect to the new one until I no longer receive redirects from there, and to then cancel the domain. Thanks to all the domain metadata websites out there, may those who run them burn in hell, my Whois will probably persist in Google's cache for some time.

Best bet is simply using (as >>3831 suggested) a rpi.

The solution to your problem of apps tracking you is flashing a basic custom ROM like whatever Cyanogenmod is called today or Paranoid Android, not installing Gapps, and just paying attention to what else you're installing after that.

You'll still might have to deal with your cell service provide selling your location data to advertisers if you live in the US, but the only way to get around that is to just not use a cell phone or leave it off whenever you aren't using it.

I'm definitely not an expert on this but I think once you enter it once the program generates a hash from the password and keeps it hidden. Everytime you change the password you'd need to regen a new hash and cracking the password locally is just finding the hash and bruteforcing it.

  No.3942

Depends on the client. The right way to do it is something like this.

Log in normally

Have the server generate a "token" of some sort, store that token in a list of tokens that correspond to that user.

Next time the user logs in, instead of presenting a password present that token (on web sites that token is stored in a cookie).

Have the server stop storing those tokens under certain conditions, such as no log-ins after a certain point.

---

For some reason most clients try to obfuscate what they're doing, even when that's what they're doing. They store the length of the password, and show some dots indicating how long it is in the password field.

Others, like ssh, make this explicit. You can't tell it to remember your password, but you can generate an SSH key, which acts very similarly to our token example.

Of course, if you're getting your browser to remember passwords for you, it is just storing the plaintext somewhere. Not necessarily in a plain text file, often in some kind of data structure, like an sqlite file or some horrible XML thing.

Tools like the pupy RAT even have modules to pull all those passwords out of those files.

In firefox at least, if you set a "master password" it no longer stores the files as plaintext on disc, it encrypts them using your master password as a key, and only unencrypts them as needed.

Just a friendly reminder your devices are listening.

While anything with a mic can potentially be hacked, its known that cell phones are mandated to have surveillance capabilities. This can bypass the OS, as the cell modems have direct memory access, and its mandated that LE has a backdoor they can use to spy on people, even if the phone is off. A battery disconnect will kill the mic.

Just reminder to treat all microphones plugged into a power source as live, unless known otherwise.

Simple countermeasures:

1. make a fairday cage. Get a box that can fit your electronics. Get some radio reflective paint. Get a box. Paint the box inside and out. Connect your phone to cell tower, blue tooth and wifi, put the phone in the box, ensure the connections die.

PROTIP: STOCK microwave ovens do not work. It should work if you spray the inside of a microwave oven. untested though.

http://www.all-spec.com/Catalog/Paints-Coatings/Coatings/Conductive-Coatings/841-340G-33018?gclid=CMG7neuQ7NECFYWCswodkfINrw

2. Step two - get a white noise generator. You can get these things at bed bath and beyond as well as target as well as the internet. They use these in doctors office to prevent people overhearing sensitive communications.

Put devices in painted box next to white noise generator.

Double pro-tip: remember security culture. If you use it like contraband, it is contraband. The entire point is to look non suspicious. If anyone asks about the items, you need plausible stories about what you are doing with them.

White noise generator is to help you sleep. They are sold as sleep aids. the RF paint is for your radio project.

Triple pro-tip: bug detectors should find people's cell phones and anything else that needs to go in the box for the conversation. Any electronics that has a wireless data interface of any kind needs to go in the box.

a vector of qbits each has a probability of being in one of two given states on observation, that looks like a probability distribution. great. now you can operate on bit vectors to change the distributions. build a circuit with gates that operate on probability distributions of qbit vectors. check the value of the output. check the value a few times. you can induce the distribution of outputs from a relatively small number of values.

good for finding collisions, not a nondeterministic turing machine, can't represent extra bits with two bits, no time travel, no infinite resources, no virtual infinite parallelism. you can solve certain probability problems in fewer cycles. algorithms will precede hardware as people do stuff with math.

so far as I understand anyway.

So, dear Lainons I want to "sign" an image with some text, not a watermark but embed my signature within the image. Maybe there will be some negligible quality loss but I'd like it to be readable by the some app.

I suppose it's similar to how layer works but would run as a stand alone application (for large image files). It doesn't use meta-data tags like EXIF or anything similar, the message would be encoded into the file. If it gets cropped, re-encoded or modified in any way, then the signature is destroyed (therefore the file is no longer authentic).

Does such a program or suite of programs exist? I know a simple screenshot will copy any image but this is more as a means to preserve the source for those interested in knowing.

General consensus on the issue (by everyone who isn't Cloudflare) seems to be that this is an exceptionally serious vulnerability that may have compromised substantial user information from almost any site that uses Cloudflare.

The current suggestion is to rotate all of your passwords for sites that may have been affected.

Examples of data that have been leaked through this vulnerability include GPS positions from Uber, authorization tokens from Fitbit mobile applications (I think?), chat messages from a popular chat client (hypothesized to be Discord), and private messages from dating sites (OKCupid).

The article seems to get one point very wrong:
>Do we worry that having put movies on the web, then content providers will want to switch also to use it for other media such as music and books? For music, I don’t think so, because we have seen industry move consciously from a DRM-based model to an unencrypted model, where often the buyer’s email address may be put in a watermark, but there is no DRM.
All those music streaming sites most certainly would move to using DRM like this if it existed, and the RIAA will be pushing for that in the future now that EME is being accepted.

>>4485
>This will make disclosing security flaws in web browsers into a criminal offense.
No, EME is just a framework for using DRM. The DRM is still a separate plugin and not an integral part of the browser.

>Working DRM is mathematically impossible.

It depends on what you consider to be "working". Due to the plugin approach that EME uses, companies can update their DRM plugin whenever people manage to break the key used. This means that companies anticipating the keys for their DRM eventually being broken can have updated versions of their DRM plugin ready to push out to users as an update the moment their previous version was broken, and after a few cycles of their DRM keys being broken would be able to anticipate the time it takes and preemptively update their DRM plugin. This is the future people chose when they started replacing local media with streaming.

People use Tor over I2P because I2P doesn't allow you to visit clearnet websites. Most people don't use software like Tor or I2P for accessing hidden services, so I2P's extra security is meaningless when they can't access the information they want over it. The ability to more securely torrent using I2P is really the only thing I can think of that I2P has going for it to attract more people, though most people are probably happier with faster download speeds at the cost of privacy/security.

A spam group "calling themselves River City Media (RCM). Led by known spammers Alvin Slocombe and Matt Ferris" has left backup servers exposed, containing operation critical files, including "a database of 1.4 billion email accounts combined with real names, user IP addresses, and often physical address".

Includes information about how they used a slowloris attack to open a ton of connections to gmail, and force it to process a massive amount of email at once.

As the article rightly points out:
>Imagine the privacy and legal implications here. Law enforcement agents normally have to go through a subpoena process before a service provider will hand over the name behind an IP address or account. This list maps out 1.4 billion.

It seems apparent that CoRegistration was a source for these collected email addresses - sites sharing details you provide with third parties. RCM themselves posed as a media company.
It makes me wonder how many other operations like this are out there, and how easy must it be to scrape personal information en masse like this.

Spamhaus has blacklisted RCM's infrastructure.

with governments forcibly demanding your passwords and cloning your whole phone to crawl through later when you travel, what solutions exist other than simply wiping your whole phone and reimaging it later(or something that might not work like pretending you forgot the battery).


It simply is a bad idea to let them trawl through your entire email and chat histories as well as every account password and detail on whatever websites you were on. It's not a question of having something to hide it's being worried about them constructing evidence from out of context information to their own benefit.
Example case: http://www.dailyxtra.com/canada/news-and-ideas/news/us-customs-block-canadian-man-reading-scruff-profile-215531


I was thinking a hidden volume style setup might help here. for example, if i unlock my phone for them using one code, it could go to the volume without any vitals on it. The other would lead to my real phone OS. It would be nice to have this not only for this specific scenario but because i'd like to be able to make calls and do simple soykaf without "unlocking" every little ounce of security i have on the device so someone could grab it out of my hand and keep it unlocked to dig through emails or some soykaf. My understanding of hidden volumes is that the use of the outer volume will destroy the hidden volume's data, which is a major problem if they go into the outer volume and start rifling through everything installed.

A layered solution could also work where you have an obviously encrypted container inside the OS but severe usability problems emerge there as well as the reliance on their laziness, they could still ask what that big inaccessible file is.

Are there any existing phone OS/implementations i can read up on that compares to this level of security?

Telling them to go fuarrrk themselves is nice when they aren't detaining you at an airport until you unlock your phone which you yourself know doesn't have anything incriminating on it, so you cave.

The issue is that even then they can construct a case against you out of thin air to fill their quotas so its best to just avoid the situation entirely. Im more likely to store an encrypted phone image on a home server or even random upload site and re-image it afterwards than i am to risk being forced to unlock my soykaf at an airport, avoiding confrontation in those circumstances is good opsec but also a good life skill.


I've heard of copperhead OS but their phone selection is incredibly limited and for half the phones it seems like they expect payment, not exactly the champion of open source security i was hoping for. I also looked at paranoid android, they seem to have full disk encryption working but also don't support my phone. Next phone purchase i make will need to take the ROM choice into account too. Its already hard enough to find a phone that meets basic requirements like sd card and removable battery damnit.

They can't keep you detained forever, so unless you're pressed for time and NEED to be somewhere within the next couple of days then think of it as a mini-vacation. It wouldn't be the worst thing you've ever experienced, I guarantee that.

>avoiding confrontation in those circumstances is good opsec but also a good life skill.

Why care about that anymore? As long as you have secure setups on your devices they can't do much to some random glitterboy who tells them to shove it. We have to resist somehow and it can't be in the shadows completely.

>Next phone purchase i make will need to take the ROM choice into account too. Its already hard enough to find a phone that meets basic requirements like sd card and removable battery damnit.


That's the sad state of cell phones today. Personally, I'm so cavalier about the whole thing because I'm fed up with this soykaf and I barely use my phone as a computer anyway. Everything worth seeing is on my laptop/desktop, which are encrypted.

Greetings Lainons. Perhaps you can help me.

We all know the NSA, CIA, FBI, the ABC, DEF, GHI and so forth are spying on us through hardware. Let's face it; its embedded in Intel and AMD cpu's at this point, and probably the motherboards as well. X86 and amd64 are no longer secure.

Now, with all that said, what are some 'open-source' hardware that have no proprietary garbage on them? Is the Raspberry Pi like this?

Greetings, fellow Lainons.

I am gravely concerned. Regardless of you're OS, regardless if you're using Libreboot and even if you do have 100% open source hardware, it raises a greater question.

How can we stop ISPs from recording our web traffic?

Granted, if you have committed no crime then you have nothing to hide. However, its a matter of principle here. What are steps we can take to privatize our online activity and at least prevent our traffic being monitored? Yes, we can use a VPN, but who is to say they are not recording our traffic as well and not using it against us?

Is this the end of the free internet as we know it?
>inb4 OP is overly melodramatic
I am only concerned for our well being and is all. I apologize if this seems heavily dramatized in anyway.

If you are in the United States, soon all ISP history and logs will be available to advertizers for sale (hopefully not, but let's be realistic, that's how security researchers should think). This means that unless you are using something like tor, i2p, or DNScrypt then these advertizers and whoever else already has access to this info that ISPs probably already collect will know all the sites you visit. How about instead of using 100% encrypted connections, setting up a pi or something to generate bogus web traffic in the clear to make you stand out far less from anyone who only or primarily connects to tor nodes and i2p routers which are fairly publicly known and can call attention to you?
This presents a similair problem to what the TOR Browser has been attempting to deal with along with the EFF, browser fingerprinting versus maximum security browsing that can be profiled. But what I think makes this different is that your ISP, unless you somehow pay them in cash, knows your real life address and your full name. Websites don't and that is why fighting browser fingerprinting is important, but does it matter if they already know who you are?
I'd be interested in what you guys think. I haven't had much time to think about the ramifications of this and it seems pertinent to OP's question.

>Granted, if you have committed no crime then you have nothing to hide.

You have plenty of reasons to hide. Medical Data is important for hiring & insurance, financial data for buying things - online shops started adjusting prices depending on the user profiles - if they know you got money up it goes and if you don't know this happens gg. Political opinions also got people fired. And of course criminals can buy the same data shopping for targets.


Now to the security troubles:
Don't forget that no matter how save your tunnel is you still need to ensure you ain't sending your ID over the tunnel. Browsers are notorious attack targets with most being contaminated themself. If javascript is enabled there is a guaranteed chance to identify you though the tunnel and the web has increasingly more sites disfunctional without enabling the tracking third party crap.

VM's + tunnel might work in a way obfuscating your real hardware wich gives you a second ID one could likewise reidentify unless you manage to change settings constantly for the VM to keep changing your possible ID. Lastly there were exploits breaking out of VM's so they can't offer absolute safety either but it's certaintly more than just allowing your real OS to be read out.

BTW ISPV6 is by design compromised but i don't remember the details. What's important is that it's recommended to stay on ipv4 when possible due to this.

I have a somewhat old laptop with Arch+i3wm installed in it, and I have some questions regarding as secure as possible browsing in it.
For professional reasons, I need to access some heavily botnet websites. I have no personal information anywhere, so it's not a very dramatic issue, but I still want to have as little as possible connections between my different browsing activities. The problem is that the only modern browsers that I can properly run in here are chromium-based. Anything related to firefox (IceCat, PaleMoon, &c) is just slow to the point of being impractical, and other lightweight browsers I've tested just wouldn't load a lot of websites around (for everything that's just simple, I'll use w3m, which I prefer anyway). So I use Iridium, which as far as these types of browsers go, I'm pretty sure is the most secure I could do.

For more specific protection, besides the basic ublock and httpseverywhere, I use uMatrix, with pretty strict rules, even though to access most common websites I end up having to let some soykaf come in. It also deletes my cookies every 15 minutes, and I only use incognito ever, so there's no continuity. But I get paranoid after being on google sites or anything similar, and don't want to leave those cookies laying around even as I go to the next site, or do anything after that.

So, I've described all this to give context to some doubts I have:
- am I just overthinking soykaf at this point in terms of browsing, and since I have to use those sites anyways, this is already as far as I can go with keeping them locked?
- what other combinations of extensions or habits I could use if the former question isn't the case? I really wish I had something like self-destructing cookies, but I couldn't find any equivalent for Iridium that was open source
- if i just delete cookies+cache as I'm using incognito (chromium-based browser do that on another, not-incognito window), because I don't want those particularly nasty cookies laying around after going to youtube, for example, even for 15 minutes, will the browser delete them for the incognito session I'm using or those will persist until I close it?
It's a really bore having to either do that, or close and open the program again just to be done with that session info before doing other stuff. I saw several extensions that do a total clean-up with one click, but all I could was closed-source.

Anyway, any help, advice, or recommendations on stuff I should read to have some new ideas would be very welcome. And I'm sorry if I should have posted this in some of the general questions threads, but I've read several of them and didn't see many posts with such broad questions, so I thought this might deserve it's own thread. Perhaps other people will like to bring their questions in this format as well.

  No.4972

DIsable javascript if it isn't already. Check if your browser is vulnerable to fingerprinting and if so try to fix it: https://panopticlick.eff.org/.
I think that with uMatrix you can change user agent. Try to copy the Tor Browser's one, since it's very common. Do you use something like a VPN or Tor? If so use your normal IP when accessing sites like Google and then switch for normal browsing. I don't know how Iridium works, but if you can try to use different profiles (or use the browser as a different user) for different browser activities and eventually for more security use a sandbox like firejail.

Going through the available documentation for the past couple hours after hearing it recommended by a glorious fluffy from one of the podcast series over at LTB.
At this moment, this project seems promising.
Think imma buy some sias in the following days, compile and install some point in the week and see if it lives up to the hype.
Any of you out there using with success?

Here's a brief explainer taken from https://sia.tech:
"The idea of Sia was originally conceived at HackMIT 2013. What if you could liberate the unused storage space of the world and unite it into a worldwide free market for data?

Sia leverages the capacity of blockchain technology to enable distributed networks to reach consensus in a secure and trustless way. Cryptographically secured smart contracts ensure the encryption and transfer of data with no possibility for a third party to interfere in any way.

Sia is a new approach to cloud storage platforms. Instead of all datacenters being owned and operated by a single company, Sia opens the floodgates and allows anyone to make money by renting out their hard drive. Data integrity is protected using redundancy and cryptography.

The promise of Sia is a decentralized network of datacenters that, taken together, comprise the world's fastest, cheapest, and most secure cloud storage platform. Today, being a major cloud storage player requires having datacenters, building trust within the market, reaching customers, and competing with giants such as Amazon, Google, and Microsoft.

Breaking into this market is a multi-billion dollar endeavor. The long term goal of Sia is to be the backbone storage layer of the Internet.

We believe data should be free. We aim to liberate the unused bits of the world and construct the largest storage superserver on the planet."

Granted, its easy enough to just image the hard drive, but again, I want to make a .vdi virtual hard drive from a physical hard drive. I'm not against paid software that does this (I think vmware does, not sure) but I want to use GNU and freeware first if any exist that does what I want.

When people talks about secure ways to communicate from a smartphone, Signal is always is the go-to choice. Except there's a few things that I personally think is annoying with this apps, like the fact it use the internet connection and make your texts go trough a SPOF (even though the transition make sense, see their blogs about it : https://whispersystems.org/blog/goodbye-encrypted-sms ).
So how to secure SMS/MMS traffic ? Since last years I've been using a fork of TextSecure 2.6.4, called Silence : https://silence.im
As explained in the first link I've put, both apps have their own pros and cons :
Pros :
>No google services dependencies
>No SPOF
>Can be your default SMS apps
Cons :
>No IOS support (there's just no API to rely on).
>Except the length of the text, you cannot obfuscate the metadata
>Encrypted texts spotted from miles ( https://github.com/SilenceIM/Silence/issues/480 )
>No calls, no video.

So, what's your personal opinion ? What do you use to keep you secure ?
