The RobinHood ransomware group is a financially motivated cybercriminal organization that emerged around 2019, though the specific variant referenced here was first observed in December 2021. The group is suspected to operate independently rather than as a Ransomware-as-a-Service model, with limited public documentation regarding their country of origin or affiliations with other threat actors. RobinHood operators typically gain initial access through exploitation of public-facing applications and vulnerable remote desktop services, deploying their custom ransomware payload that encrypts files and demands payment for decryption keys. The group has historically targeted government entities and healthcare organizations, with their most notable attack occurring against the City of Baltimore in May 2019, which resulted in significant operational disruption and recovery costs exceeding $18 million, though this earlier campaign appears distinct from the 2021 variant. Given the limited victim count and recent emergence of this particular RobinHood variant, current intelligence suggests minimal ongoing activity, though definitive assessment of their operational status remains unclear due to insufficient public reporting on recent campaigns. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on December 6, 2021. The operation is currently inactive.

If your organisation is affected
A listing by robinhood means Besson Seguros appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.
- Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
- Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
- Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
- Monitor for the data appearing on robinhood's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
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.
