Hermes

Hermes is a ransomware family. The provided content explicitly associates it with North Korea-linked activity, including use by APT38/BlueNorOff, a Lazarus subgroup focused on financial operations. APT38 is described as using Hermes ransomware to encrypt files with AES256. Hermes also appears in reporting on targeted ransomware tradecraft and in Spamhaus tracking, which identified 14 command-and-control servers associated with Hermes. The malware is additionally referenced as a secondary payload delivered by AZORult: in a July 2018 campaign attributed to TA516, victims received employment-themed phishing emails containing password-protected documents; after entering the password and enabling macros, AZORult was downloaded, which then exfiltrated credentials, cookies, system information, and cryptocurrency wallet data before downloading and executing Hermes 2.1 ransomware. The content also mentions a variant described as 'Hermes 14 eBanking Trojan,' but does not provide further high-confidence technical detail on that item. Overall, the high-confidence behavior in the supplied material is that Hermes is used for file encryption in financially motivated intrusions, has been linked to North Korean operators, and has been delivered through phishing-to-downloader infection chains involving AZORult.

MITRE ATT&CK

Techniques & procedures

2 distinct techniques documented for this family, organized by ATT&CK tactic.

Command and Control

1 technique
T1071Application Layer ProtocolEvidence1

The Spamhaus Botnet C&C (BGPCC) is designed to protect networks and their users from botnet traffic. It can be used to block traffic from/to servers on the internet that are operated by cybercriminals and used to control infected computers (bots) or exfiltrate data.

Impact

1 technique
T1486Data Encrypted for ImpactEvidence1

Multiple ransomware families and actors are described as encrypting victim filesystems/drives for extortion (e.g., Akira, Conti, Ryuk, WannaCry, NotPetya, etc.), often appending new extensions and dropping ransom notes.
