Reports can be the fun part of a pentest.. if the target uses MyReport. Lucas Laise found a third-party updater running as SYSTEM, an unauthenticated gRPC service, and a nice way to turn software updates into arbitrary code execution. From LPE to RCE🔥 blog.quarkslab.com/myreport-upd...

Not an antivirus product this time, but we couldn't pass it up 🙈 Cato Networks said: route with split tunneling. kaluche_ heard: root with split tunneling. Check out CVE-2026-10739, a LPE vulnerability in the Cato VPN Client for Windows ➡️ blog.quarkslab.com/cato-vpn-cli...

To leverage AI agents for vulnerability research, we built a hybrid source-code analysis workflow that combines deterministic analysis with agentic reasoning. Applied to FreeRDP, it helped us uncover vulnerabilities and chain them into client-side RCE. 🔗 blog.quarkslab.com/from-ai-agen...

Optical network security often sounds like an obscure incantation: PON, ONU, OLT, PLOAM, OMCI, GEM, GPON, XG-PON, 50G-PON, T-CON.. To conjure the right knowledge read Thiébaud Fuchs' overview of Passive Optical Networks and their security features blog.quarkslab.com/overview-of-...

Do you know how Entra ID applications work? What about the security mess they can bring and what they can quietly break? New blog post on Entra ID application permissions, the audit nightmare they create, and QAZPT, our OSS tool to actually make sense of it: blog.quarkslab.com/auditing-app...

Obfuscation vs The Optimizer: A Battle in LLVM Middle End. Robert Yates shows us how the continuous improvement of the LLVM optimizer defeats naive code obfuscation, and how the obfuscator can fight back. An eternal fight in which all victories are ephemeral blog.quarkslab.com/obfuscation-...

🤔Ever wondered how your favorite tools work under the hood? During our work on SightHouse, we dug into BSIM, Ghidra's Binary function SIMilarity engine. Many tools have been built around it, yet its internals remained undocumented. Until now 👇 blog.quarkslab.com/bsim-explain...

🚗 We traced a car’s life from China to Poland. By analyzing a BYD Telematic Control Unit, Romain Marchand econstructed its journey and identified a real-world event from GPS logs alone. Embedded forensics + OSINT = real stories hidden in data. 👉 blog.quarkslab.com/tearing-down...
