This SentinelOne weekly roundup (Week 39, 2026) covers one law enforcement success and two active threat campaigns. A US court sentenced Armenian national Karen Serobovich Vardanyan ("Maneeken"/"Karl Lagerfeld"), an initial access specialist for Ryuk ransomware, to two years in prison and over $1.2 million in restitution. SentinelLABS ide…
SentinelOne analysis argues that bring your own vulnerable driver (BYOVD) succeeds because of a signing-trust gap rather than an incomplete driver list. The Windows kernel loads drivers signed with expired or revoked certificates, and a 2026 intrusion reported by Help Net Security used a decade-old forensic driver whose certificate had lo…

It is a methodology piece, not a threat report: no incident, vulnerability, or…
SentinelOne argues that "EDR killer" covers four different techniques, and a single driver-load rule leaves blind spots. The four are bring-your-own-vulnerable-driver (BYOVD), bring-your-own-installer, admin-to-kernel, and driverless suspension. The article gives hunt logic for each and recommends rolling them out in order of signal quali…

Kash Patel described him as a suspected co-conspirator of ShinyHunters, though he has not been officially named as one. The FBI says the group breached more than 140 organizations an…
This SentinelOne analysis argues that EDR killing, mostly through bring your own vulnerable driver (BYOVD), has grown from one-off tooling into a maintained, shared and sold capability. Ransomware actors disabled security tools in about 48% of 2024 intrusions, and BYOVD is the fastest-growing method within that figure. The article traces …
