Exploitation and Demonstrations

Your mouse suddenly seems to take on a life of its own and clicks the pop-up.

Remediation and Defensive Strategies

Before you know it, your Windows machine belongs to me. This session breaks down an amusing and far-fetched (yet entirely technical) exploit chain, starting from the highly restrictive Chromium renderer process and escalating to kernel-level privileges by chaining and abusing three vulnerabilities: CVE-2024-5274, CVE-2024-11114, and CVE-2025-29824. I will be sharing my learnings, laughs and grief while venturing into V8, Mojo, CLFS and everything in between (i.e. Ubercage, kCFG) while attempting to make this work.
