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

瑞祥机电 (Ruixiang Jidian) was listed by Medusalocker ransomware, a group with 77 victims recorded in this database. The listing appeared on the group's leak site on September 12, 2026.

瑞祥机电 (Ruixiang Jidian) is based in China and operates in the Manufacturing sector. China ranks #28 worldwide for ransomware disclosures, with 123 victims in this database.

Sector context. Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

Medusalocker typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
