Hack a Day
Training a machine learning model is not a task for mere mortals, as it takes a lot of time or computing power to do so. Fortunately there are pre-trained models out there that one can use, and [Max Bridgland] decided it would be a good idea to write a python module to find and view such models using the command line.
For the uninitiated, Modelzoo is a place where you can find open source deep learning code and pre-trained models. [Max] taps into the (undocumented) API and allows a user to find and view models directly. When you run a utility, it goes online and retrieves the categories and then details of the available models. From then on, the user can select a model and the application will simply open the corresponding GitHub repository. Sounds simple but it has a lot of value since the code is designed to be extendable so that users working on such projects may automate the downloading part as well.
We have seen projects with machine learning used to detect humans, and with AI trending community tools such as this one help beginners get started even faster.

Thanks to the wonders of neural networks and machine learning algorithms, it’s now possible to do things that were once thought to be inordinately difficult to achieve with computers. It’s a combination of the right techniques and piles of computing power that make such feats doable, and [Robert Bond’s] ant zapping project is a great example.
The project is based around an NVIDIA Jetson TK1, a system that brings the processing power of a modern GPU to an embedded platform. It’s fitted with a USB camera, that is used to scan its field of view for ants. Once detected, thanks to a little OpenCV magic, the coordinates of the insect are passed to the laser system. Twin stepper motors are used to spin mirrors that direct the light from a 5 mW red laser, which is shined on the target. If you’re thinking of working on something like this we highly recommend using galvos to direct the laser.
Such a system could readily vaporize ants if fitted with a more powerful laser, but [Robert] decided to avoid this for safety reasons. Plus, the smell wouldn’t be great, and nobody wants charred insect residue all over the kitchen floor anyway. We’ve seen AIs do similar work, too – like detecting naughty cats for security reasons.

A question: if you’re controlling the classic video game Street Fighter with gestures, aren’t you just, you know, street fighting?
That’s a question [Charlie Gerard] is going to have to tackle should her AI gesture-recognition controller experiments take off. [Charlie] put together the game controller to learn more about the dark arts of machine learning in a fun and engaging way.
The controller consists of a battery-powered Arduino MKR1000 with WiFi and an MPU6050 accelerometer. Held in the hand, the controller streams accelerometer data to an external PC, capturing the characteristics of the motion. [Charlie] trained three different moves – a punch, an uppercut, and the dreaded Hadouken – and captured hundreds of examples of each. The raw data was massaged, converted to Tensors, and used to train a model for the three moves. Initial tests seem to work well. [Charlie] also made an online version that captures motion from your smartphone. The demo is explained in the video below; sadly, we couldn’t get more than three Hadoukens in before crashing it.
With most machine learning project seeming to concentrate on telling cats from dogs, this is a refreshing change. We’re seeing lots of offbeat machine learning projects these days, from cryptocurrency wallet attacks to a semi-creepy workout-monitoring gym camera.

When starting a new job, learning coworkers names can be a daunting task. Getting this right is key to forming strong professional relationships. [Ahad] noted that [Marcos] was struggling with this, so built the Name Stone to help.
The Name Stone consists of some powerful hardware, wrapped up in a 3D printed case reminiscent of the Eye of Agamotto from Doctor Strange. Inside, there’s a Jetson Nano – an excellent platform for any project built around machine learning tasks. This is combined with a microphone and camera to collect data from the environment.
[Ahad] then went about training neural networks to help with basic identification tasks. Video was taken of the coworkers, then the frames used to train a convolutional neural network using PyTorch. Similarly, a series of audio clips were used to again train a network to identify individuals through the sound of their voice, using MFCC techniques. Upon activating the stone, the device will capture an image or a short sound clip, and process the data to identify the target coworker and remind [Marcos] of their name.
It’s a project that could be quite useful, given to new employees to help them transition into the new workplace. Of course, pervasive facial recognition technology does have some drawbacks. Video after the break.

It isn’t often that the world of Hackaday intersects with the world of crafting, which is perhaps a shame because many of the skills and techniques of the two have significant overlap. Crochet for instance has rarely featured here, but that is about to change with [Janelle Shane]’s HAT3000 neural network trained to produce crochet hat patterns.
Taking the GPT-2 neural network trained on Internet text and further training it with a stack of crochet hat patterns, she was able to generate AI-designed hats which her friends on the Ravelry yarn forum set to crochet into real hats. It’s a follow-up to a previous knitting-based project, and instead of producing the hats you might expect it goes into flights of fancy. Some are visibly hat-like while others turn into avant-garde creations that defy any attempt to match them to real heads. A whole genre of hyperbolic progressions of crochet rows produce hats with organic folds that begin to resemble brains, and tax both the stamina of the person doing the crochet and their supply of yarn.
Perhaps most amusingly the neural network retains the ability to produce text, but when it does so it now inevitably steers the subject back to crochet hats. A Harry Potter sentence spawns a passage of something she aptly describes as “terrible crochet-themed erotica“, and such is the influence of the crochet patterns that this purple prose can even include enough crochet instructions to make them crochetable. It would be fascinating to see whether a similar model trained with G-code from Thingiverse would produce printable designs, what would an AI make with Benchy for example?
We’ve been entertained by [Janelle]’s AI work before, both naming tomato varieties, and creating pie recipes.
Thanks [Laura] for the tip.

What’s in your crypto wallet? The simple answer should be fat stacks of Bitcoin or Ethereum and little more. But if you use a hardware cryptocurrency wallet, you may be carrying around a bit fat vulnerability, too.
At the 35C3 conference last year, [Thomas Roth], [Josh Datko], and [Dmitry Nedospasov] presented a side-channel attack on a hardware crypto wallet. The wallet in question is a Ledger Blue, a smartphone-sized device which seems to be discontinued by the manufacturer but is still available in the secondary market. The wallet sports a touch-screen interface for managing your crypto empire, and therein lies the weakness that these researchers exploited.
By using a HackRF SDR and a simple whip antenna, they found that the wallet radiated a distinctive and relatively strong signal at 169 MHz every time a virtual key was pressed to enter a PIN. Each burst started with a distinctive 11-bit data pattern; with the help of a logic analyzer, they determined that each packet contained the location of the key icon on the screen.
Next step: put together a training set. They rigged up a simple automatic button-masher using a servo and some 3D-printed parts, and captured signals from the SDR for 100 presses of each key. The raw data was massaged a bit to prepare it for TensorFlow, and the trained network proved accurate enough to give any hardware wallet user pause – especially since they captured the data from two meters away with relatively simple and concealable gear.
Every lock contains the information needed to defeat it, requiring only a motivated attacker with the right tools and knowledge. We’ve covered other side-channel attacks before; sadly, they’ll probably only get easier as technologies like SDR and machine learning rapidly advance.

Chaos Communication Congress 22th (22C3) 2005 Abstract: Most technologies and techniques intended for securing digital data focus on protection while the machine is turned on – mostly by defending against remote attacks. An attacker with physical access to the machine, however, can easily circumvent these defenses by reading out the contents of the storage medium on a different, fully accessible system or even compromise program code on it in order to leak encrypted information. Especially for mobile users, that threat is real. And for those carrying around sensitive data, the risk is most likely high. This talk will introduce a method of mitigating that particular risk by protecting not only the data through encryption, but also the applications and the operating system from being compromised while the machine is turned off.

This talk is at the intersection of the two: centering around the applications and contributions to be made to Moses, a state of the art open source toolkit for statistical machine translation developed by researchers from MIT, Edinburgh, Cornell, and Aachen. In the past, those who wanted quality machine translations were forced to rely on closed source, rule based engines such a SYSTRAN. Even most of Google's translation engine uses SYSTRAN software. But Google and others are moving towards flexible, trainable systems, based on computer generated statistics rather than PhD linguist generated rules. This means a machine translation is accessible to the average user. Next time, instead of getting angry or amused by a poor translation provided by Google Translate or BabelFish, use your own copy of the open source engine and you can hack away, helping to improve translation quality for yourself and users around the globe.

log2command is a PHP script that tracks IPs in log files and executes shell commands per each IP. log2command was created as a sort of reverse fail2ban or cheap VPN-firewall: a machine with a closed firewall can be told, by a foreign machine, to accept connections from a specific IP. log2command then keeps track of the webserver log file and watches for inactivity from the user's IP. After an amount of time another command is executed that can remove the user's IP from the firewall, closing down the machine again. The PHP script is a command-line program that can be run in the background.

virtual machine malware malware analysis Event:
Black Hat USA 2010 Abstract: The increasing amount of new malware each day does not only put anti-virus companies up to new limits handling these samples for detection by creating new signatures. But also for network security providers and administrators, getting information on how samples affect the networks they try to protect is an increasing problem. Dynamic analysis of malware by execution in sandboxes has been an approach that has been successfully applied in both of these problem scenarios, however classic sandbox approaches clearly suffer from severe scalability problems. Most of these rely on setting up a real target system such as the Windows XP operating system as a virtual machine with additional software that does logging of performed actions. While these are easy to develop and set up, they require a separate virtual machine instance for each malware sample to be analyzed and therefore do not scale up with today's requirements in terms of malware growth. Anti-Virus vendors tried to circumvent performance issues for file analysis by developing custom emulators that can be deployed on a customer end-host for detection and do not require a whole operating system inside a virtual machine. These emulators however often are software interpreters for the x86 instruction set and run therefore into execution speed limitations on their own. Additionally, they suffer from detectability because they try to emulate every single Windows API but suffer from accuracy issues. dirtbox is an attempt to implement a highly scalable x86/Windows emulator that can be both used for simple malware detection and detailed behavior analysis reports. Instead of emulating every single x86 instruction in software, malware instructions are executed directly on the host CPU in a per basic block fashion. A disassembling run on each basic block ensures that no privileged or control flow subverting instructions are executed. The notion of virtual memory that is separated from the emulators memory is employed by special LDT segments and switching segment selectors before executing guest instructions. Since no instrumentation alike instruction rewriting is being done, disassembler results per basic block can be cached and all execution happens in the same process without context-switches, a high grade of performance is achieved. The operating system is emulated at the syscall layer. While this layer is mostly undocumented and implementing it in an accurate fashion is a challenging task on its own, the fact that no register changes are leaked from Ring 0 thwarts a lot of detection techniques. For usage of the high-level APIs, corresponding libraries are directly mapped into the virtual memory as well.

We usually avoid the prospect of buying new tools just for one project. In the long run we’re sure we’d use them again, but sometimes even with that outlook you can’t afford it. Case in point is our life-long-lust for a laser cutter; we just can’t justify the upfront cost but we sure would use [...]

Hi, i can easily crack my WPA password which i set to a dictionary word recently.
However i now want to change the password to password123.
I have heard john the ripper can add 123 ...etc to each individual passphrase so I would like to do that.
After catching the handshake I notice that there are 4 packets called 'KEY'
Is this the 4 way handshake?
If so how to i get the 'hash' or password information from my handshake and transfer it manually to my windows machine to experiment with. Or what do i need to copy over?
Thanks

Hello,
I've installed BT4 on a VMware Workstation.
But for some weird reason it can't see any of my network drives, I have both Ethernet and WiFi.
I tried to play with the VMware network setting for this machine, NAT and Bridge, nothing.
Also, I installed the machine as Ubuntu, I figured since both Ubuntu and BT4 are based on Debian it should be ok.
I tried to look through the forum but was unable to find anything related threads that can fix my problem.
Any advice?
Thank you.

Hello All,
I have an HP machine with a Dual Boot of Vista and BT4PF. I want to upgrade to BT4F, though. I'll probably install it in a virtual machine or on a USB drive...
Anyway, I am worried about ruining my windows partition. I have read posts online about formatting from the Windows OS and then changing the boot.ini file. WELL... That is all fine and dandy, and I will do that but I wanted to check with you all here to see if there are any suggestions or words of wisdom. Maybe I should go about this differently?
Also, random question: If I were to install the BT4F version on VirtualBox, could I save files and settings (persistent?) and still shutdown... without using this "snapshot" technique?
Thanks fellas
