12/30/2022 0 Comments Vulnerable windows images![]() ![]() Microsoft released a patch to address the Windows Hello biometric authentication vulnerability on July 13, 2021, Patch Tuesday, alongside other bugs like PrintNightmare. ![]() Microsoft mitigation does not fully address Windows Hello vulnerability The researcher noted that the vulnerable biometric authentication system was more insecure than a password because a person’s face was out there. Therefore, manipulating this information can lead to a potential bypass to the whole authentication system,” they wrote. ![]() “The sensor is a device that transmits information on which the OS, in particular Windows Hello, makes its authentication decision. This condition allows a threat actor to manipulate the input and trick the operating system through the plugged camera that acts as an external data source. Tsarfati noted that the exploit could be extended to other authentication systems that allow biometric authentication using pluggable third-party USB cameras as the biometric sensor. They could achieve this by converting a regular RGB frame to IR. They only need to send a single genuine IR image to pass authentication. RGB image (Color image).” They also noted that USB devices could be cloned to look like others, while IR images could be generated out of regular color images.Īn attacker requires a USB camera supporting both RGB and IR images. The research referred to Microsoft’s disclosure “that people tend to look very different in a Near IR image vs. With this new custom USB camera, we transmitted valid IR frames of our “target person,” while the RGB frames we sent were images of SpongeBob, and to our surprise, it worked!” “For this purpose, we used an evaluation board manufactured by NXP. ![]() Also, although my XP VHD images are also a base platform, I can provide a fully hardened (extremely secure) copy of the VHD images I provide, once again, upon request.“To verify this, we did an experiment in which we created a custom USB device that acts as a USB camera with IR and RGB sensors,” the researcher wrote. I can provide an open virtualization file (OVF) of either VHD upon request, and I can even offer other fully configured VHD images (depending on software availability and compatibility). I offer the Windows XP in two VHD flavors a Hyper-V image for those who want something small or a testing system, and a universally compatible VMware image of XP 圆4 for advanced users who need more, or have advanced or powerful systems. This is the most fake thing I've ever seen- XP "MODE" is a proprietary windows-7 only cheap imitation of the real Windows XP Virtual Machine!įor all I know, your so called "virtual machine" is full of viruses and malware- any experienced user or professional will tell you that new installations of operating systems, especially Windows, are the most vulnerable to security threats!!! Seriously, you posted the XP MODE crap here, and stole the name of MY VHD page!?! ![]()
