WPA2 protocol attack Anonymous 10/17/2017 (Tue) 06:41:08 [Preview] No. 11568 [Reply] [Last 50 Posts]
https://www.krackattacks.com/

>We discovered serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Concretely, attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.

>The weaknesses are in the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected. To prevent the attack, users must update affected products as soon as security updates become available. Note that if your device supports Wi-Fi, it is most likely affected. During our initial research, we discovered ourselves that Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others, are all affected by some variant of the attacks. For more information about specific products, consult the database of CERT/CC, or contact your vendor.

The Q&A is worth reading, and has information on attack mitigations. Unfortunately, if you are using an Android smartphone that isn't receiving updates anymore, your WiFi security on that device is probably null.

Trying not to be annoying, but you really have to back shit up on an imageboard.
If people don't believe you they won't bother fact checking, and if they do believe you but don't have a link they'll leave with information that they have no means to back up.

He was challenged to post an attack or attacks that make that statement true. He failed to do so, because he's also a stupid motherfucker.

I'll mostly agree with the second, although it's easy to attack some devices than others. The first one not so much.

In the future, anyone who can build a desktop will also be able to build a laptop. This is the entire point of a free hardware project like this.

Free Hardware is not blobbed nor tivoized, not backdoored at the software, firmware and hardware level, and not designed to fail as soon as warranty expires.

Free Hardware running Free Software is the only solution to the modern craptop.

CPU, RAM, GPU: 1x single board computer

A Single Board Computer provides every component needed to build laptop, except for battery, display, keyboard and case, each of which can be added separately.

Single Board Computers provide CPU, RAM, GPU, motherboard and some other integrated features on a single board. They are full desktop computer system that is sufficiently small and low power consuming to be used as a mobile, DIY laptop. They are also very low cost (<$50).

The most important feature of Single Board Computers is that there are models that are fully open source. It is possible to build a fully functional laptop with Free Software only, including free firmware, wireless and 3D video acceleration drivers. It is even possible to get SBCs with open source hardware designs.

For reference:

Single Board Computers with free 3D video acceleration (Etnaviv)
Nitrogen6X ($225): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC2000, 2 GB DDR3, best option, compatible with mainline kernels
Nitrogen6_MAX ($299): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC3000, 4 GB DDR3, faster Nitrogen6X
Wandboard QuadPLUS ($139): Quad core ARM A9 @ 1 Ghz, Freescale i.MX6, Vivante GC3000, 2 GB DDR3, cheaper version of Nitrogen6_MAX, not mainline

Open source hardware Single Board Computers
BeagleBone Black ($55): Single core ARM A8 @ 1 GHz, TI Sitara AM335x, PowerVR SGX530, 512 MB DDR3, fully open source except GPU, mainline compatible, https://github.com/beagleboard/beaglebone-black

Charger

The DIY Modular Open Source Laptop is designed to be charged by any combination of solar panel, handcrank generator, USB AC adapter, USB car charger, USB port or thermoelectric generator. Unlike most rechargeable electronics, each charger can charge the USB powerbank battery of the DIY laptop seperately from the DIY laptop. This flexible and modular charging ensures the DIY laptop never runs out of energy, yet never needs to be charged either.

For reference
USB solar charger: SOKOO 22W 5V 2-Port USB Portable Foldable Solar Charger ($55)
Handcrank generator: K-TOR Pocket Socket Hand Crank Generator Portable Power Supply 10 Watts 120 Volts ($60)
Pedal generator: K-tor Power Box 20 Watt Pedal Generator ($200)
Thermoelectric generator: Camping Stove Thermoelectric Generator TEG Power - Devil Watt 15 Watt ($304)

Each reference charger can provide the 5V 2A needed to charge a USB powerbank at full speed. The most convenient charger will depend on the situation.

Solar panels can provide >150 W unattended outdoors at daytime.
Handcrank or pedal generators can provide <150 W attended indoors or outdoors, day or night. Handcrank generators can be used while standing or moving, but pedal generators can be used while also using the DIY laptop.
Thermoelectric generators can provide >150 W unattended outdoors, day or night. Indoors with ventilation.
USB AC adapters can be used wherever there is AC electric grid.
USB car adapters can be used with most DC electricity sources such as 12 V car batteries or six 1.5 V AA batteries in series. USB car adapters can also convert DC from solar panels, thermoelectric generators, handcrank generators, DC wind or hydroelectric turbines into 5V DC for charging the DIY laptop.

This machine before your eyes is extremely powerful, a machine that grants its user access to all of the information conceived by the human species. It is capable of performing highly complicated mathematical calculations thousands, possibly millions of times faster than your typical human, and can store massive amounts of information, perhaps a library filled with thousands of books stored on this little machine, too massive for a measly individual to read in their lifetime, is reality.

When these sophisticated and wondrous machines had begun to appear in the 80's and 90's, the savvy individuals saw them for what they were, highly capable machines that would greatly change the world. They had taken advantage of this, and they became the first hackers, people armed with these extremely powerful tools. Companies and marketers observed this new medium and knew they could gain great wealth using it, and the mainstream mediums with the purpose of entertaining were born.

If only people knew just how powerful that little "phone" in their hand truly was. What a great time to be alive, so many ignorant fellows bickering about the problems in the world and how the past was such a great era, with no knowledge of what is truly happening at this moment.

I don't think I'm that intelligent. Really.
Actually, if you haven't understood the statements above, then it's my fault, not yours.

What you have said is true, except that there is no distinction between "computers" and "internet", it's the same. The interpretation of the informations on this internet is that is distinct from the computers.

About the text above (>>11303), I probably haven't explained properly.
Let's come back and do an analysis of your OP. You said:
>access to all of the information conceived by the human species.
That is not true, because we can access on computers only the information we produced, not the information we thought. Inside our heads there's much more information, that we can't express because these informations are not capable of being expressed with normal language (scripted or phonetic). That's why we have art, but even with art, complex thoughts can't be expressed because they are more of an experience through senses.
>performing highly complicated mathematical calculations
It does, but we should not just assume that mathematics is the "truth language". This is silly. Mathematics is a language used to express classical logic. So we should question if this classical logic is correct. If you go down the "rabbit hole", you'll notice that the foundations of science is not as solid as people think.

So, on my first comment I was just criticising your argument about "access to all of the information", basically.


About your AI idea, it seems cool, but that will take a huge effort and our understanding about human thoughts is not entire predictable, since we have no predictable model of the mind yet, and without all the variables you can't calculate.

All computers do past its true value as an efficiency chamber is create the illusion that an individual can achieve something when it's actually achieved by society as a whole. OP is wrong. Computers aren't helping us build cathedrals more magnificent or formulate philosophy more poignant, if anything it convinces us of the unworthiness of such attempts at beauty. What are hackers known for, the really good ones? Petty leeching off of society's existing structures, but in a very efficient way.

Basically, anything particularly useful that's done with computers is already done by massive superclusters that there can only be a few of in existence, or its tasks that have been done for ages by houses full of several people. It can be done by a single person with a PC, but giving them all a PC will not stack and only gets you repeated instances of those people doing the same thing over and over again. Ten million athletes will improve the world record only by milliseconds from the record of one million athletes. All it does is the athletes become less versed with anything else and become obtuse and preoccupied with their field, worse philosophers and worse voters.

Meanwhile, the only real innovation of personal computing is that once dumbed down enough we can now decrease the amount we actually have to commute to the same building to work.

Bit torrent and P2P communities will be what temporarily saves the internet for past and current generations. Future generations won't know anything about the current internet and less than 1% will ever use P2P software rendering the internet into commercialized networks much like we see on TV.

I agree, backup everything and make sure you have multiple backups. But this won't save the internet forever as the mindless public capitulates to the total destruction of everything that made the internet so great.

If the original intenet ever goes, I'll go with it, and I won't be buying a bunch of "smart" tech or other commercialized crap. I'll be reading books, watching DVDs, throwing darts and drinkin' booze from a jar again. Going back to simpler times like the early 80s.

I desire to learn C/C++ as they appear to be most suitable to my needs, and I would like some advice as to where I can begin and what existing software programs/Operating systems will be most useful to me.

Are the books written by Dennis Richie/Bjarne Stoustrup my best bet?

Not sure what your ideas are but these books should cover the bases. You have: "Beginning Programming with Python For Dummies" to start, followed by "Python 3 Object-Oriented Programming, 2nd Edition." Those are must read beginner material, fly through those. Then you have "Beginning Game Development with Python and Pygame" and "MakingGames" the second one being just fun to play around with. Then you have "Violent_Python_A_Cookbook_for_Hackers" if that is more your interest. You might want the Kivy documentation in case you want to make phone applications. Python being the easiest language with the most user friendly tools, documentation and community means this should be a cake walk for most people with an interest. Lastly you need to get IDLE with Python 3, because that's what these tutorials will teach.

C is a fine start for beginning programming. Consider that 90% of everything you use on a daily basis is written in C, and in most cases, the working core was written by one person. Linux, Windows, Bind, Apache, Sendmail, and Postgres, for example, are all written in C.

Use whatever operating system you want, and install a command-line based C compiler like gcc. Use whatever tutorial you want and write a program that prints your name ten times and then exits. If, upon seeing that work for the first time, you experience an endorphin rush unlike anything else you've felt before, congratulations. You probably won't be able to stop, and it'll just keep getting better and better the more you keep digging into it. If on the other hand you feel mostly irritation about all the fiddly crap you had to do to get that far, you are not a programmer. While continued use of all the fancy tools and languages that have been created over the past 20 years to "improve" programming or make it "easier" might allow you to create some things, it's going to be neither easy nor satisfying and the results will, frankly, not be that great.

yeah, C's printf formatting is daunting at first. All you really need to get going though is %s for text, %d for ints, %f for floats, and a newline \n at the end.


printf("%s %d\n", "the universal number is", 42);

You can look for yourself on radb.net or using whois(1).
If you want to block those, use this command and put on your router firewall:

If you end up building a lot of this stuff, check out Kynar, also known as wire-wrapping wire, as an alternative to solid-core copper for the longer point-to-point connections on boards like that. It's a solid core 30AWG, so a smaller gauge, but very strong. I find it easier to work with, though it does need a little stripping tool (cheap) and a pair of needle-nosed pliers to take a little bit of insulation off the ends without mangling it.
