RingSafe analysis

Bring-Your-Own-Vulnerable-Driver remains a top-five EDR-evasion technique in 2026, and this research lowers the bar further by letting researchers (and attackers) interact with vulnerable kernel drivers without owning the hardware they were written for. The practical consequence for Indian defenders: assume vulnerable drivers are reachable, do not rely on “no hardware present” as a mitigating control, and expect a larger pool of BYOVD-armed loaders in commodity ransomware affiliates targeting Indian SMBs and mid-market. Action: deploy Microsoft’s Vulnerable Driver Blocklist with HVCI and Memory Integrity on every Windows endpoint; tighten driver allow-listing under WDAC; map your EDR’s BYOVD-detection coverage to MITRE ATT&CK T1068 (Privilege Escalation) and T1014 (Rootkit). For Indian BFSI under the RBI framework, this is a “reasonable security safeguards” gap auditors will increasingly ask about — document the control or be asked why you have not.
