Because the driver carries a legitimate Microsoft signature, traditional allowlisting controls may fail to block it at the kernel level. This technique is especially dangerous because it operates with ring-0 privileges, effectively blinding security tools before an attacker moves to encryption or lateral movement. The ransomware's rebrand from Beast also highlights how threat actors recycle and evolve tooling to evade signature-based detection, making behavioral and driver-level controls critical.","**Immediate Actions:**\n- Enable Microsoft's Vulnerable Driver Blocklist (HVCI \u002F Memory Integrity) on all Windows endpoints to block known malicious or abused drivers.\n- Audit and inventory all kernel drivers currently loaded across endpoints, flagging any unsigned or anomalously signed drivers.\n- Apply the latest Windows security updates to ensure driver signature revocations are current.\n\n**Detection Measures:**\n- Deploy behavioral EDR rules to alert on any process that attempts to load a kernel driver followed by termination of security processes.\n- Monitor Windows Event Logs (Event ID 7045, 6) and Sysmon (Event ID 6) for unexpected driver load events, particularly from temporary or user-writable paths.\n- Integrate threat intelligence feeds to receive timely updates on newly identified BYOVD drivers and add them to blocklists proactively.\n\n**Long-Term Improvements:**\n- Enforce a strict application and driver allowlist policy using Windows Defender Application Control (WDAC) to prevent unauthorized kernel-mode code execution.\n- Implement network segmentation so that a compromised endpoint cannot freely communicate laterally, limiting ransomware propagation.\n- Establish a tested backup and recovery program with offline, immutable backups to ensure business continuity in the event ransomware encryption succeeds.",[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 18: Penetration Testing","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 SP 800-83: Guide to Malware Incident Prevention and Handling","MITRE ATT&CK T1068: Exploitation for Privilege Escalation","MITRE ATT&CK T1562.001: Impair Defenses – Disable or Modify Tools","MITRE ATT&CK T1014: Rootkit (BYOVD technique)","Microsoft HVCI \u002F Memory Integrity Driver Blocklist Policy",{},"published","2026-07-09T12:21:25.274498+00:00","2026-07-09T12:21:24.981+00:00",{"id":7,"url":28,"slug":29,"title":30},"https:\u002F\u002Fthehackernews.com\u002F2026\u002F07\u002Fgoddamn-ransomware-uses-poisonx-driver.html","goddamn-ransomware-uses-poisonx-driver-to-disable-endpoint-defenses-d49881","GodDamn Ransomware Uses PoisonX Driver to Disable Endpoint Defenses",[32,38,44],{"id":33,"name":34,"slug":35,"description":36,"color":37},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":39,"name":40,"slug":41,"description":42,"color":43},"859cf0ad-a7e9-42bb-a75d-bac6511fa5d5","Configuration Management","configuration-management","Misconfigs, default credentials, exposed services","#eab308",{"id":45,"name":46,"slug":47,"description":48,"color":49},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[],[52,56,60],{"slug":53,"name":54,"problem":55},"privileged-access-management","Privileged access management (PAM)","Admin accounts stop being one stolen password away from control of everything.",{"slug":57,"name":58,"problem":59},"endpoint-management","Device management (MDM and UEM)","Every company laptop and phone is known, encrypted, locked down and up to date.",{"slug":61,"name":62,"problem":63},"endpoint-detection-response","Endpoint detection and response (EDR and XDR)","Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped."]
