Layered Binary Templating

Research output: Chapter in Book/Report/Conference proceedingConference paperpeer-review

Abstract

We present a new generic cache template attack technique, LBTA, layered binary templating attacks.
LBTA uses multiple coarsergrained side channels to speed up cache-line granularity templating, ranging from 64 B to 2 MB in practice and in theory beyond.
We discover first-come-first-serve data placement and data deduplication during compilation and linking as novel security issues that introduce sidechannel-friendly binary layouts.
We exploit this in inter-keystroke timing attacks and, depending on the target, even full keylogging attacks , e.g., on Chrome, Signal, Threema, Discord, and the passky password manager, indicating that all Chromium-based apps are affected.
