KelvinSecurity is a relatively minor ransomware operation that emerged in April 2022, primarily motivated by financial gain through extortion activities targeting various organizations. Based on limited publicly available intelligence, the group appears to operate independently with no confirmed nation-state affiliations or clear ransomware-as-a-service model, though their specific country of origin remains undetermined. The group's attack methodology follows conventional ransomware patterns, though specific details regarding their initial access vectors, encryption methods, or data exfiltration practices have not been extensively documented by major security research organizations or government agencies. KelvinSecurity has maintained a relatively low profile compared to major ransomware families, with approximately 26 documented victims since their emergence, suggesting they target smaller to medium-sized organizations rather than high-value enterprise targets that typically attract significant media attention or detailed threat research. As of current reporting, the group appears to remain active but continues to operate below the threshold that would typically prompt major law enforcement disruption operations or extensive public threat intelligence reporting from agencies like CISA, FBI, or leading security firms. The group has been linked to 26 public disclosures across our corpus. First observed on a leak site on April 1, 2022; most recent post May 24, 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.
