Advanced Extortion Threat: Symantec Details 'GodDamn' Ransomware Weaponizing PoisonX Driver
Executive Summary
Threat hunting and security research teams have published a detailed, forensic deep-dive into a highly sophisticated and aggressive new ransomware family tracked under the moniker GodDamn. Detailed in threat intelligence reports published on July 10, 2026, by Symantec and Carbon Black, the ransomware is a highly calculated rebrand of the notorious Beast and Monster ransomware families developed by the cybercrime syndicate Hyadina. The most dangerous operational advancement of GodDamn is the integration of PoisonX, a custom-compiled, malicious driver used to execute Bring Your Own Vulnerable Driver (BYOVD) attacks. By loading this cryptographically signed, vulnerable driver into memory, the ransomware executes arbitrary kernel-space commands to bypass Windows Driver Signature Enforcement (DSE), directly terminating active security agent processes (MsMpEng.exe and enterprise EDR agents) from active RAM before starting the file encryption loop.
Deep-Dive Technical Analysis
The developer behind GodDamn, tracked by researchers as Hyadina, has a long-standing history of developing destructive ransomware strains. The lineage began with Monster ransomware in November 2022, rebranded to Beast in June 2024, and has now evolved into GodDamn as of late May 2026.
A forensic analysis of the GodDamn execution chain and the PoisonX BYOVD attack vector outlines a highly calculated, multi-stage bypass:
* Initial Access and Dwell Time: Threat actors typically gain initial access to the target network using compromised credentials or exploiting public-facing remote access portals. The attackers maintain a substantial "dwell time" (averaging five days) to map out Active Directory structures, harvesting passwords using tools like AnyDesk, NetScan, Mimikatz, and NirSoft.
* Deploying the PoisonX Driver: To completely blind the local security team, the ransomware drops and registers a legitimate, digitally signed third-party kernel-mode driver known as PoisonX. Because the driver possesses a valid signature, the Windows operating system allows the load to succeed, bypassing standard Driver Signature Enforcement (DSE).
* The BYOVD Exploit (EDR Killing): The GodDamn ransomware communicates with the loaded PoisonX driver via custom input/output control (IOCTL) codes. By exploiting a known memory-corruption vulnerability within the driver, the malware executes arbitrary commands with kernel-level privileges (Ring 0). From this privileged position, the malware directly terminates the active processes and handles of all registered Endpoint Detection and Response (EDR) agents and antivirus services, rendering the host completely defenseless.
* Volume Shadow Copy Deletion and Encryption: With all security monitoring and telemetry disabled, the malware executes administrative commands to permanently delete local Volume Shadow Copies (vssadmin.exe delete shadows /all /quiet). It then initiates its high-frequency asymmetric encryption routine, appending customized extensions to all local files and dropping a README_DECRYPT.txt ransom note.
By combining the credentials-harvesting efficiency of its predecessors with the EDR-killing power of the PoisonX BYOVD exploit, the GodDamn ransomware ensures that once the encryption phase begins, local security teams are completely blind to the attack.
Industry Impact and Recommendations
The evolution of the Hyadina syndicate's payloads into the GodDamn ransomware demonstrates that traditional endpoint security tools are no longer sufficient to protect enterprise networks. When malware can load trusted, signed drivers to directly terminate local security agents from memory, defenders must transition to proactive, kernel-hardening policies.
We recommend that all system administrators, Windows infrastructure leads, and SecOps teams implement the following mitigations:
1. Enable Microsoft's Vulnerable Driver Blocklist: Ensure that Microsoft Defender's Vulnerable Driver Blocklist is actively enabled on all managed Windows endpoints via Group Policy (GPO) or MDM configurations. This cloud-synchronized blocklist prevents the system from loading known vulnerable signed drivers.
2. Enforce Driver Blocklist Hardening via WDAC: Configure Windows Defender Application Control (WDAC) to block the execution and loading of unauthorized third-party kernel drivers. Enforce policies that restrict driver loading to a highly limited, verified whitelist of corporate-approved hardware drivers.
3. Monitor for Anomalous Driver Registration Events: Configure SIEM and EDR tools to monitor Windows Event Logs (specifically Event ID 7045 - "A new service was installed in the system"). Immediately flag and isolate any instance where an uncharacteristic or non-standard kernel driver service is registered, especially if spawned by temporary user folders.
4. Implement Tiered Administrative Access: Restrict local administrative rights. Because BYOVD attacks require administrative privileges to register and load driver services, enforcing strict standard-user profiles and standardizing least-privilege configurations on standard workstations completely neutralizes the execution path.
