Darkleakmarket is a financially motivated ransomware group that emerged in September 2021, primarily targeting organizations in the United States across finance, healthcare, technology, and energy sectors. The group has claimed responsibility for attacks against 39 known victims, though specific details about their country of origin and potential affiliations with other cybercriminal organizations remain undocumented in public threat intelligence reports. Limited public information exists regarding their specific attack methodologies, initial access vectors, or whether they employ double extortion tactics involving data theft prior to encryption. No major high-profile campaigns or significant law enforcement actions against Darkleakmarket have been publicly documented by major security agencies or researchers. The current operational status of this group remains unclear due to the limited public reporting and intelligence available about their activities since their initial emergence. The group has been linked to 39 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post June 17, 2025. 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.
