What it detects

This rule detects the loading of a kernel driver signed with the revoked or expired certificates reused by the AVKiller EDR killer shared across multiple ransomware operators. The driver carries a randomized name and fake CrowdStrike version information but is signed by the revoked Changsha Hengxiang or expired Fuzhou Dingxin certificates, a strong indicator of bring your own vulnerable driver abuse.
