SLAP and FLOP: Apple Silicon Speculative Execution Attacks

from Connected Components of Chaos Hosted by AmCan Tech

SLAP and FLOP are two new speculative execution attacks targeting Apple's M-series chips. SLAP exploits the Load Address Predictor (LAP) to leak data by predicting incorrect memory addresses, while FLOP leverages the Load Value Predictor (LVP) to predict incorrect data values. Both attacks allow unauthorized access to sensitive information from web browsers like Safari and Chrome, compromising data ranging from email content to financial details. Researchers demonstrated proof-of-concept attacks recovering data like browsing history and even book excerpts. Mitigation requires software patches from vendors and updated operating systems.
