robinhood (also tracked as HelpYemen) is a ransomware operator no longer publishing new disclosures. Darkfield has indexed 1 public victims claimed by this operator between December 6, 2021. 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.
