Payload Ransomware claimed it breached Royal Bahrain Hospital in Bahrain and stole 110 GB of data, then listed the hospital on its Tor leak site with a deadline to pay before the data is released. The reporting says the gang published screenshots or images of allegedly compromised systems as proof of access, and described Payload as a relatively new double-extortion operation targeting mid- to large-sized organizations, including healthcare entities, with pressure tactics based on both data theft and encryption.
Technical analysis of the Payload malware links the operation to a Babuk-derived codebase and says the ransomware uses ChaCha20 for file encryption and Curve25519 for key exchange, with no identified cryptographic weakness that would allow recovery without the attackers' private key. Researchers also noted distinctive detection artifacts, including a 56-byte footer encrypted with an RC4 key of FBI, and assessed that while Payload has been described as ransomware-as-a-service, there is no public evidence yet confirming an affiliate program; what is confirmed is the group's recent activity, leak-site operations, and the Royal Bahrain Hospital claim as one of its named victims.

3 events from the most recent confirmed update back to the earliest known activity.
On 2026-03-15, the Payload ransomware group listed Royal Bahrain Hospital on its Tor leak site, alleging it stole 110 GB of data. The group published screenshots of allegedly compromised systems and threatened to release the data if a ransom was not paid by 2026-03-23.
Derp.Ca analyzed Payload's Windows and Linux/ESXi variants and concluded the ransomware is heavily derived from the leaked Babuk source code, with modifications including ChaCha20 encryption, Curve25519 key exchange, ETW patching, event log wiping, and anti-forensic self-deletion. The analysis also noted 12 claimed victims across seven countries totaling 2,603 GB of allegedly stolen data.
Researchers reported that the Payload ransomware strain has been active since at least 2026-02-17, targeting organizations in multiple sectors and countries using a double-extortion model.
