GootKit
Intelligence Profile
Gootkit is a banking trojan consisting of an x86 loader and a payload embedding nodejs as well as a set of js scripts. The loader downloads the payload, stores it in registry and injects it in a copy of the loader process. The loader also contains two encrypted DLLs intended to be injected into each browser process launched in order to place the payload in man in the browser and allow it to apply the webinjects received from the command and control server on HTTPx exchanges. This allows Gootkit to intercept HTTPx requests and responses, steal their content or modify it according to the webinjects.
Threat Analysis
GootKit 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 GootKit 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, GootKit is capable of targeted intrusions using adapted commodity tools alongside custom implants, maintaining operational security and evading standard detection mechanisms.
