Cheers is a relatively obscure ransomware group that emerged in May 2022, primarily motivated by financial gain through extortion activities targeting organizations in the United Kingdom. The group's origin and potential affiliations remain largely undocumented in public threat intelligence reporting, with limited information available about whether they operate as an independent entity or utilize a Ransomware-as-a-Service model. Based on their targeting patterns, Cheers appears to focus on critical infrastructure and essential services sectors, having affected approximately 15 known victims across transportation, finance, and healthcare industries primarily within the UK. Due to the group's relatively small victim count and limited public documentation by major security firms and law enforcement agencies, specific details about their attack methodology, encryption techniques, initial access vectors, and extortion tactics have not been widely reported or analyzed in available threat intelligence sources. The current operational status of the Cheers ransomware group remains unclear, as there is insufficient publicly available intelligence from reputable sources to definitively assess whether they remain active, have ceased operations, or undergone rebranding. The group has been linked to 15 public disclosures across our corpus. First observed on a leak site on May 29, 2022; most recent post September 14, 2022. The operation is currently inactive.
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.
