Check out our latest blog post by my awesome teammate @pseudohvr! He shares details of a recent BlackByte #ransomware intrusion, and *of course* shared actionable detection opportunities. #threatintel
With help from our partners @KrollWire, #RCIntel analyzed a BlackByte ransomware sample and uncovered details about its initial access, post-exploitation, and exfiltration phases prior to encryption. redcanary.com/blog/blackbyte…

Levar Burton can't be the new host of the show because Captain Picard would never willingly put a member of his crew in Jeopardy

Part of my role is ensuring we're *not* EDR-centric. We have to be able to detect threats w/o OS-level viz (e.g., control plane only), using auth/net events, or whatever data is in a SIEM
It's where we need to be to protect our customers

Such blatant stereo-typing.
