According to Sophos X-Ops (Aug 06, 2025), a widely shared EDR-killer toolkit drops/loads a malicious kernel driver signed with compromised or revoked certificates to disable endpoint protections. Variants target many vendors, and are commonly HeartCrypt-packed and used by ransomware groups (e.g., RansomHub, INC). The payload uses hard-coded driver names (e.g., mraml.sys, noedt.sys) and kills security services/processes.
