Intelligence Profile

This information-stealing malware exfiltrates data from its victims and uploads this information to its web server for publication. It can capture data from browsers, the clipboard and the local disk to steal sensitive data such as credit card details, browser cookies, crypto wallet information, File Transfer Protocol (FTP) and virtual private network (VPN) credentials.

Threat Analysis

Gremlin is a malware family tracked by threat intelligence researchers and catalogued in the Malpedia dataset. It represents a distinct malicious software lineage with identifiable code characteristics, behaviors, and victimology.

The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.

Classified as an advanced threat actor, Gremlin likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
