This project consists of 3 parts.
1) A script (gpu-pt-check.sh) that automatically checks to what extend a computer is compatible with GPU pass-through in its given configuration.
2) A script (setup.sh) that automatically installs and configures your system for GPU pass-through (Only tested on fresh installs of Fedora 28 x64 with Gnome, booted in UEFI mode!)
3) Instructions on how to create a bootable Linux USB stick that automatically runs the gpu-pt-check.sh script when you boot from it without any user interaction required.

Industrial Control Systems (ICS) are sensible targets for high profile attackers and advanced persistent threats, which are known to exploit USB thumb drives as an effective spreading vector. In ICSes, thumb drives are widely used to transfer files among disconnected systems and represent a serious security risks, since, they may be promiscuously used in both critical and regular systems. The threats come both from malware hidden in files stored in the thumb drives and from BadUSB attacks . BadUSB leverages the modification of firmware of USB devices in order to mimic the behaviour of a keyboard and send malicious commands to the host. We present a solution that allows a promiscuous use of USB thumbs drives while protecting critical machines from malware, that spread by regular file infection or by firmware infection. The main component of the architecture we propose is an hardware, called USBCaptchaIn, intended to be in the middle between a critical machine and all USB devices. We do not require users to change the way they use thumb drives. To avoid human-errors, we do not require users to take any decision. The proposed approach is highly compatible with already deployed products of a ICS environment and proactively blocks malware before they reach their targets. We describe our solution, provide a thorough analysis of the security of our approach in the ICS context, and report the informal feedback of some experts regarding our first prototypes.
This is not a new release, but I’m catching up with USB security tools for this blog.
Umap2 is the second revision of NCC Group’s python based USB host security assessment tool. Umap2 is developed by NCC Group and Cisco SAS team.
* USB device emulation
* USB host scanning for device support
* USB host OS detection (no implemented yet)
* USB host fuzzing
* USB host fuzzing uses kitty as fuzzing engine
[…I’m sure many of us already have one of these multi-port usb chargers to charge all our gadgets. So my idea was to create a casing for an RPi that looked like one of those chargers.[…]
Smartphones have been charged over USB for many years, but with the advance of USB type-C now even laptops may be charged over USB, instead of the typical DC power barrel jack.[…]
Lots of general debugging skills for Windows USB drivers covered in this blog post.
Eclypsium has created a new CHIPSEC module to see if USB Debug attacks are possible!
[…]In the fourth developer beta of iOS 12, a passcode is required any time a computer or USB accessory is connected.[…]
[…]In other words, we have found no obvious way to break USB Restricted Mode once it is already engaged. However, we discovered a workaround, which happens to work exactly as we suggested back in May[…]

WooKey: USB Devices Strike Back

The USB bus has been a growing subject of research in recent years. In particular, securing the USB stack (and hence the USB hosts and devices) started to draw interest from the academic community since major exploitable flaws have been revealed by the BadUSB threat. The work presented in this paper takes place in the design initiatives that have emerged to thwart such attacks. While some proposals have focused on the host side by enhancing the Operating System’s USB sub-module robustness, or by adding a proxy between the host and the device, we have chosen to focus our efforts on the device side.
Malware regularly uses USB sticks to infect victims, and the abuse of USB sticks is a common vector of infection (as an example Lost USB keys have 66% chance of malware). CIRCLean is an independent hardware solution to clean documents from untrusted (obtained) USB keys / USB sticks. The device automatically converts untrusted documents into a readable but disarmed format and stores these clean files on a trusted (user owned) USB key/stick. The focus of CIRCLean is to establish document exchange even if the used transport layer (the USB stick) cannot be trusted or if there is a suspicion about whether the contained documents are free of malware or not. In the worst case, only the CIRCLean would be compromised, but not the computer reading the target (trusted) USB key/stick. The code runs on a Raspberry Pi (a small hardware device), which also means it is not required to plug the original USB key into a computer. CIRCLean can be seen as a kind of air gap between the untrusted USB key and your operational computer. CIRCLean does not require any technical prerequisites of any kind and can be used by anyone. CIRCLean is free software which can be audited and analyzed by third-parties. We also invite all organizations to actively reuse CIRCLean in their own products or contribute to the project.[…]
