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 56 public disclosures across our corpus. First observed on a leak site on August 16, 2023; most recent post September 25, 2026. The operation is currently inactive.

If your organisation is affected

A listing by Metaencryptor means PKF Hadiwinata appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Monitor for the data appearing on Metaencryptor's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
