Who they are

Hermes is a ransomware family first observed in the wild in February 2017, believed to have been developed by a group operating out of Asia. It originally appeared as a Ransomware-as-a-Service (RaaS) offering on underground forums but later saw deployment in targeted attacks. Hermes uses AES-256 encryption to lock victim files and appends a variety of extensions (including .hrm and campaign-specific variants). The ransom note, often named DECRYPT_INFORMATION.html or DECRYPT_INFORMATION.txt, provides payment instructions via email. The ransomware gained notoriety in 2018 when it was used as a destructive wiper in the Far Eastern International Bank (FEIB) heist in Taiwan, where attackers deployed Hermes to cover their tracks after a SWIFT fraud operation. Over time, Hermes code has been re-used and integrated into other ransomware families, including some Ryuk builds, suggesting code sharing or purchase from the original developer. Distribution vectors have included phishing campaigns, malicious attachments, and exploitation of RDP services.

Descriptions are compiled from public reporting and vendor research. They describe how a group has historically operated and can lag its current behaviour; the status and timings above are our own.

Current status

Hermes's leak site is not answering. Sites go dark for infrastructure trouble, a deliberate quiet period, or a takedown, and a good number return weeks later under the same name, so the entry stays on the list either way.

Which organisations this group has named, and when, is part of the SINON platform rather than this page. Create an account to search it, or to be told automatically if a name you care about turns up.

Sectors targeted

Industries this group has been observed going after, most common first.

This group does not state an industry on its site, so we have nothing reliable to report. Most crews are opportunistic rather than sector-specific in any case — they hit what they can reach.

Watching for your name

If Hermes posts your company, a supplier or a subsidiary, you want to hear it from us rather than from a journalist. SINON checks these sites continuously and alerts on the names you give it.
