Windows malware toolkit providing covert remote access through abused RMM software, persistent self-restoration via scheduled tasks, WMI event subscriptions, and backup copies, and Chromium-browser credential theft. A keeper component monitors remediation activity, exfiltrates host and Windows-log artifacts, and can retaliate against containment by disabling Microsoft Defender, stopping endpoint-security products, or silently uninstalling security agents.
Gryxa is a financially motivated modular malicious toolkit delivered likely through phishing. It establishes redundant scheduled-task and WMI persistence, downloads components over HTTPS while bypassing TLS revocation checks, steals Chromium-browser credentials by bypassing Chrome App-Bound Encryption, identifies cryptocurrency-wallet extensions, validates stolen credentials against cryptocurrency-exchange and fintech domains, and exfiltrates data through Telegram. It also disrupts Defender and EDR tooling when its relay is unavailable, removes competing remote-access tools, and retains a monitoring component that collects host remediation and forensic artifacts after visible RMM removal.
