First blog post in a mini series where I look at "disposable tooling". This post shares what I have found to be useful when 1-shot'ing LLM generated Stage-0 agents for Mythic. specterops.io/blog/2026/06/2…

Outflank's ntlmrain takes Google's ~8 TiB NetNTLMv1 rainbow tables and losslessly compresses them to ~3.99 TB using globally sorted endpoints, packed 39 bit chain starts, delta encoding + Rice-16 coding, and a global GIDX index. The result is ~1 min SSD table lookups, WebGPU-accelerated DES precomputation/verification, and ~7 min end-to-end cracking on an RTX 4070 Ti. More Explanation in their blog: outflank.nl/blog/2026/09/08/… Github tool: github.com/outflanknl/ntlmra… NTLMRain Table: lookup.ntlmrain.com #NetNTLMv1

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

For more than 2 years now the Red Team at MDSec have been running riot in environments by abusing ServiceNow. Today we are releasing more of our research in this space: mdsec.co.uk/2026/08/when-it-… The TLDR - popping ServiceNow is one of the most impactful things you can do.

Want to run an entire Tailscale daemon from memory inside a C2 implant with zero disk artifacts, no kernel drivers, traffic indistinguishable from HTTPS to a CDN, and relay connections from the victim network back through the tailnet. Now you can. Enjoy! netspi.com/blog/technical-bl…

Compromise one node in a Windows Server Failover Cluster and you've compromised all of them. @unsigned_sh0rt dug into why: shared credentials, forged tickets, and a full attack chain to own the cluster. Check it out! ghst.ly/4wSZSoW

I have suspected the klist.exe could be used to dump local tickets but never had time to check that out correctly. This guy did and explains it very well! Only requires local admin rights, no system, to dump all TGT's on the computer jakeotte.com/posts/klist-rev…

Onelogon: Taking over Active Directory Accounts via Netlogon🔑 We analyzed Netlogon, bypassed the Zerologon patch, resulting in a full auth bypass. An attacker can leverage this to compromise computer accounts, or even the entire AD. Non-standard config must be present tho 🧵

shipping: WinSSHound maps SSH access in AD as BloodHound paths. because Windows OpenSSH cheerfully ignores your "Deny Logon" GPOs (pre-2025) and on a default sshd_config every Authenticated User in the domain can walk right in. Why? Because Microsoft. github.com/1r0BIT/WinSSHound

It's been a while since I wrote a blog post. My new post writes about some cool updates to the MS-RPC-Fuzzer for recursively fuzzing complex structures, logging using ETW, and we found a way to escalate to nt\authority system! incendium.rocks/posts/Fuzzin…

I just dropped some research: DSCourier and would love for your opinion and to check it out!! It’s a novel post-exploitation technique abusing WinGet’s COM API to execute code through Microsoft-signed binaries. GitHub: github.com/DylanDavis1/DSCou… Blog: dylansec.com/DSCourier/

someone at ANTHROPIC just showed CLAUDE finding ZERO DAY vulnerabilities in a live conference demo claude has found zero day in Ghost, 50,000 stars on github, never had a critical security vulnerability in its entire, history... it found the blind SQL injection in 90 minutes, stole the admin api key, then did the exact, same thing to the linux kernel
