The technical heart: vulnerability research, disclosure, threat analysis, the craft of finding and fixing
Peacetime cyber versus wartime cyber
Cyber defense doctrine was built during 15 years of peacetime; the transition to wartime and austerity demands a rewrite of what we accept as polite.
AI isn't the problem — asymmetry is
AI isn't the security problem — it widens the asymmetry between vulnerability discovery and remediation, putting attack capability in many more hands.
Mythos feels a lot like Snowden
Mythos is to vulnerability awareness what Snowden was to surveillance: the moment the zeitgeist finally caught up to what insiders already knew.
Security-focussed test/fix is basically “sparkling QA”
A short reaction to Firefox's claim that AI-found defects are finite: security-focused test-and-fix is basically QA wearing a fancier hat.
Spicy Takes from my Aikido Security Podcast
Nine takes from my RSAC conversation with Mackenzie Jackson on Aikido's Secure Disclosure podcast — on bug bounty, AI slop, hack-back, vibe coding, and why the internet still working is a minor miracle.
Offense Scales with Compute. Defense Scales with Committees.
Why AI is widening the attacker-defender gap faster than anything we've built to close it — and what that actually means for the next decade of security.
Why Security Teams Gaslight Hackers: Disclosure Reality
The cybersecurity industry has a dirty secret: security teams are systematically dismissing legitimate vulnerability reports from ethical hackers. In a recent episode of Hackers
Bug Bounties in the Age of AI
As AI accelerates the offense-defense asymmetry, bug bounties and vulnerability disclosure remain essential. Casey Ellis on the future of bug bounties, the evolving threat landscape, and how disclose.io and the SRLDF protect the researchers keeping us safe.
The FCC Just Banned Every Foreign-Made Router
The FCC added every foreign-made consumer router to the Covered List — a March 2026 supply-chain action that goes far beyond previous adversary-nation bans.
Vulnerability economics
The four-line economic frame for every vulnerability: cost to introduce, cost to discover, cost to fix, and the value of exploitation — and why the math matters.
I Made AI Clones of Me and Matt Devost Argue About Exploit Stockpiling. They Agreed on a Framework.
Matt Devost and I have been circling the same set of questions for years: should governments stockpile zero-days? When does offense help defense?
For the Love of the Game: DistrictCon's Year 1 Junkyard
Notes from judging DistrictCon's Junkyard Year 1 — a Pwn2Own-style exploit contest targeting end-of-life devices. Disco balls, DNA sequencers, gym treadmills, and self-propagating game worms. Includes exploit chain diagrams for all eleven talks.
