Disclosure context

About ransomed

The ransomed ransomware group is a relatively new cybercriminal organization that emerged in August 2023, primarily motivated by financial gain through extortion activities targeting organizations across multiple countries. Based on their targeting patterns across Japan, Brazil, Russia, Great Britain, and Bulgaria, the group appears to operate internationally without clear geographic limitations, though their country of origin and potential affiliations with other ransomware groups remain undetermined due to limited public intelligence reporting. Given the recent emergence of this group and lack of detailed technical analysis from major security firms, their specific attack methodologies, initial access vectors, and encryption techniques have not been comprehensively documented in publicly available threat intelligence reports from CISA, FBI, or established security researchers. The group has claimed approximately 68 victims across their identified target countries since becoming active, though no specific high-profile campaigns or notable ransom demands have been publicly reported by law enforcement or security organizations. As of current reporting, the group appears to remain active with continued victim claims, though the limited public documentation suggests they operate as a lower-profile ransomware operation compared to more established and widely-tracked ransomware families. The group has been linked to 68 public disclosures across our corpus. First observed on a leak site on August 21, 2023; most recent post October 30, 2023. The operation is currently inactive.

If your organisation is affected

A listing by ransomed means Optimity UK 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.
Report the incident to your national CERT, NCSC (United Kingdom), as required for your jurisdiction.
Monitor for the data appearing on ransomed'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.
