Reynolds Ransomware Embeds BYOVD Driver to Disable EDR Security Tools
Summary
The Reynolds ransomware family incorporates a BYOVD technique, embedding a vulnerable driver to escalate privileges and disable endpoint detection and response (EDR) tools. This tactic allows the ransomware to bypass security measures more effectively. Researchers have disclosed details of this new ransomware family.
IFF Assessment
The use of BYOVD in ransomware makes it harder to detect and remove, which is bad news for defenders.
Severity
Defender Context
Defenders need to enhance their monitoring for driver-based attacks and review their EDR configurations to ensure they are not susceptible to known vulnerable drivers. This trend highlights the increasing sophistication of ransomware, requiring a multi-layered security approach that includes driver security monitoring and behavioral analysis. Staying up-to-date with the latest threat intelligence on emerging BYOVD techniques is critical.
