This attack highlights a critical gap in trusting code-signed drivers without validating their behavioral context, as attackers exploit the implicit trust operating systems place in signed components. The ability to operate at the kernel level means conventional antivirus and EDR solutions can be neutralized before they can respond. This matters enormously because once security tooling is disabled, attackers operate with near-impunity, accelerating encryption and exfiltration with little chance of early detection.","**Immediate Actions:**\n- Enable Microsoft's Vulnerable Driver Blocklist (HVCI \u002F Memory Integrity) on all Windows endpoints to block known-abused drivers.\n- Audit all kernel-level drivers currently loaded across your environment and flag any not explicitly approved by your organization.\n- Ensure EDR\u002FAV solutions have tamper protection enabled so they cannot be disabled by unauthorized processes.\n\n**Long-Term Improvements:**\n- Implement a driver allowlisting policy using Windows Defender Application Control (WDAC) or equivalent to restrict which drivers can load at the kernel level.\n- Establish a formal Vulnerable Driver Management program that tracks CVEs associated with signed-but-vulnerable drivers and enforces timely blocklist updates.\n- Apply the principle of least privilege across all endpoints to limit the ability of processes to load unsigned or non-approved kernel modules.\n\n**Detection Measures:**\n- Configure SIEM rules to alert on unusual driver load events, especially those loading drivers not present in your approved baseline.\n- Monitor for process behavior consistent with security tool termination, such as sudden stops of EDR or AV services, and trigger automated incident response workflows.\n- Leverage Windows Event ID 7045 and Sysmon Event ID 6 to detect new or unexpected driver installations in near real-time.",[12,13,14,15,16,17,18,19,20,21,22],"CIS Control 2: Inventory and Control of Software Assets","CIS Control 10: Malware Defenses","CIS Control 13: Network Monitoring and Defense","NIST SP 800-53 SI-3: Malicious Code Protection","NIST SP 800-53 CM-7: Least Functionality","NIST SP 800-53 AU-12: Audit Record Generation","NIST CSF DE.CM-4: Malicious Code Detection","NIST CSF PR.IP-1: Baseline Configuration","Microsoft HVCI (Hypervisor-Protected Code Integrity) Guidance","MITRE ATT&CK T1068: Exploitation for Privilege Escalation","MITRE ATT&CK T1562.001: Impair Defenses – Disable or Modify Tools","published","2026-07-09T10:20:22.826156+00:00","2026-07-09T10:20:22.744+00:00",{"id":7,"url":27,"slug":28,"title":29},"https:\u002F\u002Fwww.darkreading.com\u002Fcyberattacks-data-breaches\u002Fgoddamn-ransomware-byovd-smite-companies","goddamn-ransomware-uses-byovd-to-smite-us-companies-fc049f","'GodDamn' Ransomware Uses BYOVD to Smite US Companies",[31,37,43],{"id":32,"name":33,"slug":34,"description":35,"color":36},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":38,"name":39,"slug":40,"description":41,"color":42},"1732a005-556e-411c-a9db-5edec3058571","Logging & Monitoring","logging-monitoring","Missing logs, no alerting, blind spots","#a855f7",{"id":44,"name":45,"slug":46,"description":47,"color":48},"859cf0ad-a7e9-42bb-a75d-bac6511fa5d5","Configuration Management","configuration-management","Misconfigs, default credentials, exposed services","#eab308",[]]
