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…
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…
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 …
TrustedSec (author Brandon Colley) publishes practical guidance on building an effective logging, auditing, monitoring and alerting program for Active Directory (AD). It is based on recurring logging and auditing gaps found in the firm's AD assessments, where logging is treated as a switch to flip rather than a discipline owned by someone…
Toy Ghouls (aka Bearlyfy, Laboo.boo, Feral Wolf), a financially motivated group targeting Russian organizations since 2025, was observed in early July 2026 using a custom backdoor for the first time. Kaspersky GERT identified two versions, mqtt-bird-agent 0.1.0 (C2 over the public HiveMQ MQTT broker) and matrix-bird-agent 0.1.0 (C2 over a…
ESET Research reports that the China-aligned APT group FamousSparrow has been using a new modular C++ backdoor, SparroWocky, since at least August 2025. The backdoor has replaced SparrowDoor as the group's main implant. From mid-2025 into 2026, about 90% of the group's targets in ESET telemetry were in Latin America, mostly governmental e…
Kaspersky's analysis of Operation FlashHole describes a Lazarus Group campaign against South Korea that follows Operation SyncHole. The earliest evidence dates to July 2025, and the campaign was observed in January. At least three organizations in the software, construction and wired communication equipment manufacturing sectors were affe…
SentinelOne reports observing APT29 (Midnight Blizzard / Cozy Bear, Russia's SVR) running the CaptiveCrunch campaign, disclosed by Microsoft in July 2026, across multiple customer environments in three regions. The operation abuses captive-portal behaviour and forged name resolution to push fake browser updater downloads to roaming Window…
