HiddenTear
Intelligence Profile
HiddenTear is an open source ransomware developed by a Turkish programmer and later released as proof of concept on GitHub. The malware generates a local symmetric key in order to encrypt a configurable folder (/test was the default one) and it sends it to a centralized C&C server. Due to its small payload it was used as real attack vector over email phishing campaigns. Variants are still used in attacks.
Threat Analysis
HiddenTear 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.
Financially motivated threat actors like HiddenTear prioritize monetary gain through methods such as ransomware deployment, banking trojans, cryptocurrency theft, BEC scams, or credential harvesting for resale on underground markets.
With high sophistication, HiddenTear is capable of targeted intrusions using adapted commodity tools alongside custom implants, maintaining operational security and evading standard detection mechanisms.
