Last week, a backdoor was discovered in xz-utils. The backdoor processes commands sent using RSA public keys as a covert channel. In order to prevent anyone else from using the backdoor, the threat actor implemented a cryptographic signature check on the payload. I have seen a number of people claim that this would necessarily result in an obviously invalid RSA public key, or at least one with no corresponding private key. This is incorrect, and someone nerd sniped me into proving it.| rya.nc

Background - Why Wii U? The Wii U has had a fairly small homebrew scene, I believe in part because it currently has no commercial nor open-source modchips for facilitating early-boot code execution. While there exists a coldboot boot1 vulnerability, isfshax, it leaves a lot to be desired, and it is unfortunately not useful for recovering consoles from an unknown state, since NAND is encrypted per-console based on an OTP key. Additionally, certain SEEPROM corruptions can cause consoles to neve...| [Segmentation Fault]
Last year I detailed a secure EL3 vulnerability which affected (and still affects, for devices with discontinued updates) LG Android devices. However, this vulnerability alone isn’t actually all that useful for a number of reasons, the more immediate being that many phones simply do not allow writing to eMMC without root or a custom recovery. Additionally, gaining full control over all privilege levels requires draining the battery to below 0%, which while it would be possible to create a m...| [Segmentation Fault]
