RobinHood is a ransomware group that emerged in April 2019, primarily motivated by financial gain through targeted attacks against government and municipal organizations. The group's origin remains unclear, though they appear to operate independently rather than as a ransomware-as-a-service model, with no confirmed state sponsorship or clear geographical attribution. RobinHood's attack methodology involves deploying ransomware that encrypts victim files and demands payment for decryption keys, though specific details about their initial access vectors and technical tools are limited in publicly available documentation. The group gained attention for targeting government facilities, with their attacks causing significant disruption to municipal services, though the small number of documented victims suggests either selective targeting or limited operational scope. Current intelligence indicates minimal recent activity from this group, suggesting they may have ceased operations, rebranded, or been absorbed into other ransomware operations, though definitive confirmation of their current status is not available in public threat intelligence reporting. The group has been linked to 2 public disclosures across our corpus. First observed on a leak site on April 10, 2019; most recent post May 7, 2019. 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.
