My first love was pcap, so I kinda hope for a resurgence of NSM/NDR, but like the -NG++ version of it

Garden plants left alone tend to overgrow themselves, become brittle, imbalanced, blossom less, yield less. Many do not truly thrive without routine care and aggressive pruning. I think of this often about detection rules, workflows, tools, and "the way we do things."

We cannot thank @TrinityCyber enough for providing valuable intel on CVE-2023-20198 last month. 🤝 With this information, we acted quickly and got a tag out! Grateful to be able to work together to keep our customers safe + secure.

Officially on the job market today. Anyone looking for an old TI guy with a "smidge" of years under his belt, let me know. Happy to have a chat.

PaperCut server exploits are in the wild; here’s how you detect the first stage: HTTP GET/POST + URI ending in “SetupCompleted” AND HTTP Response “200 OK” + header “Set-Cookie: JSESSIONID=“ with a valid token. Go hunt for this! #ThreatHunting

#100DaysofYARA LNK files often store a CLSID in the TargetID fields - the previous file we looked at (GOLDBACKDOOR) did not include this header, so I suspected looking for LNKs without that CLSID might surface some anomalies More on LNK file structure: u0041.co/blog/post/4

I’m looking for an experienced (3-5 years+) threat hunter who’s comfortable with both network traffic and static file analysis. You find it, you can actively take it out with @TrinityCyber tech. This you? Shoot me a DM

Having grown up in a state that’s got trigger laws going into effect as we speak - I’m beyond disappointed at SCOTUS ruling. This is a brutal attack on women’s health, bodily autonomy, and a 50 year regression for America. I’ll always support the right to choose.
