Secure systems can still create insecure paths. @hdmoore shows how relationships between systems create hidden exposures, and how to uncover them at scale with BloodHound OpenGraph and Cypher. #SOCON2026

“Palo Alto firewalls may have dominated attacker attention for a time, but 2025 showed how quickly the spotlight shifts when a new access vector proves just as effective. Firewalls are still foundational boundary controls, but attackers like them too.” - @hdmoore at #SOCON2026

🔈 New podcast alert! @HDMoore discusses runZero's upcoming 4.9 release on @riskydotbiz with @caseyjohnellis. Hear how we're tackling converged IT/OT network challenges! 🎧 Listen to the full interview to learn more: runzero.com/resources/risk… #OTsecurity

...In which @hdmoore and I go "full packet-rat" and dig into what @runzero have been developing to support the complicated , fragile, often safety-critical OT and ICS world. If you've ever knocked over a dusty Solaris box with an nmap scan before (and want to understand how to find it without doing that), this one is for you.

Hey want to see GPT-5.4 writing a browser exploit to pop xcalc on Netscape Navigator 5.0 running on RedHat Linux 5.2 i386

@lcamtuf It was a sad day when we had to roll out identity verification before people could download the Metasploit Framework... 🤣

I still remember when I had to put out a press release saying that afl-fuzz was too dangerous to make available to the general public

In converged IT/OT environments, hidden connections, unknown assets, and gaps in visibility can give threat actors the advantage. Watch this interview (clip & full length) to learn how runZero can help! 📺 Full interview: runzero.com/resources/ot-s… #OTsecurity #OT
