This week, we are joined by Hosein Yavarzadeh from the University of California San Diego, as he is discussing his work on "Pathfinder: High-Resolution Control-Flow Attacks Exploiting the Conditional Branch Predictor" This paper introduces new methods that let attackers read from and write to specific parts of high-performance CPUs, such as the path history register (PHR) and prediction history tables (PHTs).

These methods allow two main types of attacks. One can reveal a program's control flow history, as shown by recovering a secret image through the libjpeg routines. The other enables detailed transient attacks, demonstrated by extracting an AES encryption key, highlighting significant security risks for these systems.
