KittyKatKrew is a recently emerged ransomware group first observed in February 2026, appearing to be financially motivated based on their limited but targeted attack pattern. The group's origin and potential affiliations remain unknown due to their recent emergence, and it is unclear whether they operate as an independent entity or utilize a Ransomware-as-a-Service model. With only two documented victims to date, the group's complete attack methodology has not been fully characterized by security researchers, though their targeting of financial services suggests a focus on high-value sectors that may yield significant ransom payments. The group has primarily targeted entities within the United States, with their victims spanning financial services and other unspecified sectors, though no major high-profile campaigns or record ransom demands have been publicly documented by federal agencies or established threat intelligence firms. Given their recent emergence and limited victim count, KittyKatKrew appears to be in early operational stages and remains active as of current reporting. The group has been linked to 2 public disclosures across our corpus. First observed on a leak site on February 23, 2026; most recent post February 25, 2026. The operation is currently active.
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.
