A deep dive into Ange Albertini-style funky file format covering Polyglots or Angecryption.

Explore how to reverse engineer a USB device’s communication protocol using tools like lsusb, usbmon, and Wireshark, then implement a custom Linux kernel driver to handle its input/output by directly interfacing with its USB endpoints. The driver will specifically target the DualShock 4 controller.

This article aims to give an in depth description on EUCLEAK, an attack that was discovered by NinjaLab. Focusing on how side-channels attacks were used to exploit a vulnerability found in ECDSA implementation in YubiKey 5 Series and to reverse engineer the ECDSA algorithm.
