How Medusalocker is documented to operate

Parent PID Spoofing T1134.004 Stealth Privilege Escalation

Adversaries may spoof the parent process identifier (PPID) of a new process to evade process-monitoring defenses or to elevate privileges. New processes are typically spawned directly from their parent, or calling, process unless explicitly specified. One way of explicitly assigning the PPID of a new process is via the <codeCreateProcess</code API call, which supports a parameter that defines the PPID to use. This functionality is used by Windows features such as User Account Control (UAC) to correctly set the PPID after a requested elevated process is spawned by SYSTEM (typically via <codesvchost.exe</code or <codeconsent.exe</code) rather than the current user context.

Incident Analysis

Elken Sdn Bhd was targeted by Medusalocker ransomware, one of the most active ransomware groups in our database with 51 confirmed victims globally. The attack was disclosed on May 5, 2026, when Elken Sdn Bhd appeared on the group's dark web leak site.

Elken Sdn Bhd is based in Malaysia , operating in the Consumer Services sector. Malaysia ranks #24 globally for ransomware attacks, with 127 victims in our database.

Sector context: Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

Medusalocker typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data. Last data update: Sep 5, 2026 18:00 UTC.
