Just like chocolate and peanut butter, runZero and BloodHound are an amazing combination. Today we are introducing runZeroHound - an open source toolkit for bringing runZero Asset Inventory data into BloodHound attack graphs, using the brand new OpenGraph feature in BloodHound v8. Check out the announcement and open source code at: https://www.runzero.com/blog/introducing-runzerohound/

SpecterOps released "DumpGuard" along with a detailed article on how they were able to bypass Windows Credential Guard in both privileged and unprivileged contexts. I learned a ton about Isolated LSA and friends. Its funny to see that DES-cracking of NTLMv1 challenges is still relevant (and that https://ntlmv1.com/ has supplanted https://crack.sh).

Today's runZero Hour is up with Rob King, Tod Beardsley, and EOL expert and technology necromancer, captn3m0 (pronounced “nemo”). They will summon and explore runZero’s latest research paper, “Undead by design: Benchmarking end-of-life operating systems”, which digs deep in real customer networks to get a sense of just how prevalent running EOL OSes are – and it's spine-chilling!

#SectorCa 2025 is fantastic! I last attended in 2008 and holy cow has it grown. Great to see Brian and Bruce still involved. Excellent talks, really sharp crowd, zero attitude, and everyone is incredibly friendly. You can find the slides from my morning keynote at https://hdm.io/decks/Sector-25-Moore-TheOnceAndFutureRules-FINAL.pdf
Hello #SecTor! 🍁 Rob King's presentation starts NOW in Room 716B:
"Pay No Attention to the Device Behind the Curtain: Banned tech doesn’t always stay banned. Rob shows how to detect white-labeled and counterfeit gear using Internet-scale methods & protocol quirks."

I chased an intermittent DNS bug for two weeks and for once, it was not DNS:
"PF states limit reached"
If you use opnsense/pfsense, the default state table size of 1.6m can sneak up on you when your network is full of scans. Poking around with `pfctl -si` and setting a much healthier max with aggressive expiration made everything happy again.
Related, runZero handles this problem by actively tearing down middle-box state tables during SYN scans, which ironically means sending twice as many packets, but having a much lower impact on the network as a result.
Hello Austin-area software engineers (or aspiring engineers)! Join us tonight, Wednesday, August 13, 2025 for two hours of lightning talks and discussion at the ATX Go meetup. The focus tonight is on infosec/cybersecurity/hacking tools written in Go, but all Go-related talks are welcome.
