Disclosure context

About Metaencryptor

Metaencryptor is a relatively new ransomware group that emerged in August 2023, operating with primarily financial motivations and targeting organizations across multiple sectors and geographical regions. The group appears to be an independent operation rather than a Ransomware-as-a-Service model, though limited public documentation makes definitive attribution challenging regarding their specific country of origin or connections to established cybercriminal networks. Based on their targeting patterns, Metaencryptor demonstrates a preference for manufacturing organizations, business services, and transportation/logistics companies, with their operations concentrated primarily in Western nations including Germany, the United States, Canada, Spain, and the United Kingdom. With 31 documented victims since their emergence, the group represents a moderate but persistent threat in the ransomware landscape. However, due to their recent emergence and relatively lower profile compared to major ransomware families, comprehensive technical analysis of their attack methodologies, encryption techniques, and specific initial access vectors has not been extensively documented by major cybersecurity firms or government agencies. The group's current operational status remains active as of available intelligence, though the limited public reporting suggests they operate with a smaller scale and lower visibility than prominent ransomware-as-a-service operations that typically attract more attention from law enforcement and security researchers. The group has been linked to 31 public disclosures across our corpus. First observed on a leak site on August 16, 2023; most recent post June 24, 2025. The operation is currently inactive.

Attack summary

Severity: high — Data has been confirmed published by the threat actor, meaning exfiltration and public disclosure have occurred. An educational institution holds PII on adult students (names, contact details, possibly financial-aid and health/social information), making the exposure significant even without an explicit data-volume count.

Metaencryptor claims to have compromised GO! CVO Antwerpen and has published data (disclosed status: data_published); the leak post cites a figure of $72 M, which appears to be misrepresented as revenue rather than a ransom demand. No explicit data-volume figure was stated, but the data_published status indicates exfiltration and public release of victim data.
