Paper on prompt injection delivered through forensic evidence, where the seized device's contents are attacker-controlled and the examiner must read them. It extends the anti-forensic model to cover manipulation of the reasoning layer and gives a taxonomy (objective, technique, payload location, concealment). Three proof-of-concept attacks on an LLM-assisted analysis pipeline change a reported conclusion, write attacker-chosen content to the analyst workstation, and trigger outbound network traffic. Mitigations are proposed.

RingTrace is a monitoring framework that detects Flush+Reload cache side-channel attacks by combining per-core cache-miss counters with slice activity across uncore CBoxes. Its Joint Spatio-Temporal Attribution (JSTA) builds a joint-activity matrix without model training: the largest entry is the screening score and row sums point to a candidate core. The authors report detection before secret leakage, fewer false alarms under heavy memory load, and negligible runtime overhead on commodity processors.

This repository ships poc_109618.py, a fully automated four-stage HTTP exploit that leaks ASLR offsets via Set-Cookie headers against php:8.4.26-apache on Debian Bookworm, along with a root-cause C source patch, mitigation scripts to disable session.upload_progress, and WAF/ModSecurity/Lighttpd/Apache rules plus detection guidance for anomalous PHP worker child processes. Confirmed PHP versions include 8.4.4 and 8.2.34, with EOL branches (5.x, 7.x, 8.0, 8.1) left without official vendor patches.
