Gentlemen Ransomware

It relies on diverse utilities including PsExec, WMIC, and remote PowerShell commands.

Upon execution, the payload aggressively executes PowerShell commands to disable Microsoft Defender real-time monitoring.

The attackers staged the ransomware from an internal server and leveraged built-in propagation and Group Policy (GPO) to trigger near-simultaneous execution of the encryptor across domain-joined systems.

The application also clears the local Security and System event logs using the wevtutil utility.

For example, it forcibly deletes Volume Shadow Copies via administrative command utilities.

The worm systematically attempts 21 distinct remote execution operations against each discovered network host.

The malware immediately prepares the infected machine to function as a primary distribution hub. Then, it copies itself into a temporary folder and establishes a hidden network share.

Concurrently, the application exfiltrates confidential corporate files to cloud storage repositories.

However, processing large databases completely would require excessive time. Therefore, the malware encrypts three distinct chunks distributed across the target asset. Operators can customize this speed dynamically using command-line arguments like --fast or --ultrafast. | The threat actors consistently deploy destructive double extortion tactics against their targets. First, the malware systematically encrypts critical production assets to halt local business operations.

Next, the payload terminates an extensive directory of active corporate services and applications. The targeted processes encompass enterprise databases, virtualization modules, and email management software.

To prevent file restoration, the threat systematically eliminates local system recovery markers. For example, it forcibly deletes Volume Shadow Copies via administrative command utilities.

For instance, it generates a temporary file named wipefile.tmp to fill all remaining disk space with random data. This process completely overwrites unallocated sectors to obstruct digital forensic tools.

Concurrently, the application exfiltrates confidential corporate files to cloud storage repositories. The attackers then threaten to release this data publicly if the corporate victim refuses payment.

Upon execution, the payload aggressively executes PowerShell commands to disable Microsoft Defender real-time monitoring. Furthermore, the malware adds its own binary to the localized exclusion list. It then excludes the entire local C:\ volume from future security scans.
