CTGREP is a compiler-based framework that applies differential analysis across the whole Clang/LLVM compilation chain to find where, how and under which configurations compiler optimizations break constant-time cryptographic code. Applied to seven libraries, three Clang versions, six targets and thousands of configurations, it led to 48 cases fixed with developers. It also identified seven new problematic LLVM passes and bypassed existing compiler-flag mitigations.

AWS Security Blog describes a three-layer AI-assisted pipeline for triaging vulnerability scanner findings: Layer 1 cross-checks multiple scanners (e.g., Semgrep, CodeQL) for agreement, Layer 2 verifies a scanner's claimed data-flow path against the code's actual abstract syntax tree to catch hallucinated findings, and Layer 3 cross-references infrastructure-as-code (CloudFormation/Terraform) to weigh whether existing controls like AWS WAF rules actually mitigate the exploit path. It argues progressive, escalating-evidence filtering plus mandatory structural verification of LLM claims before human review is what turns noisy scanner output into a short, trustworthy, prioritized list, and lays out an adoption order (indexing, then multi-scanner triage, then AI hypothesis generation, then infra context, then live PoC verification).

Android-Pentesting-Skill is an open-source "skill" package that turns an AI coding agent (Claude Code, OpenCode, etc.) into an Android APK security auditor. It orchestrates APKTool/JADX decompilation, MASTG-aligned Semgrep static rules, source-to-sink tracing, a Runtime Defense Analysis engine that maps detected RASP/anti-tampering protections (root detection, SSL pinning, Frida detection, SafetyNet, Approov, DexGuard, etc.) to reusable Frida bypass profiles, and CVSS 4.0/MASVS-scored professional reporting, plus smali patching/repackaging workflows for authorized lab use. It ships 37+ bundled Frida scripts, 70+ Semgrep MASTG rules, and framework-specific handling for Flutter, React Native, Cordova, and Unity apps.

A GitHub repo of n8n automation blueprints for security teams, organized into Red Team/Pentest, Blue Team (SOC/DFIR/TI), AppSec/DevSecOps, and Platform/General categories. Each of the ~90 workflow ideas gives a Purpose, Integrations, and Flow Outline (e.g., subdomain recon hubs, attack-surface diffing, GoPhish campaign launchers, C2 event forwarding, phishing auto-triage, SAST-on-PR with Semgrep, DAST nightly with ZAP, container image policy gates, CVE prioritization with EPSS/KEV) that map to concrete n8n nodes and real security tools like Subfinder, Nmap, Shodan, Trivy, MISP, and VirusTotal.

A practical walkthrough of memory forensics on a macOS (Mountain Lion 10.8) RAM dump using Volatility's mac_ plugins, covering OS version fingerprinting via string grep, obtaining/building a matching Volatility profile, listing and dumping processes (mac_pslist, mac_psaux), extracting cached files (mac_list_files, mac_dump_file), recovering bash history (mac_bash), and parsing Safari web history from plist and Cache.db SQLite artifacts. Useful as a concrete reference for analysts lacking documentation on macOS-specific Volatility workflows, with a follow-up post promised for Keychain/Evernote analysis.
