Remediation Steps:
Isolate the affected machine from the network immediately to prevent data exfiltration. Run a full antivirus scan to remove the threat and any dropped components. Since this is an information stealer, reset all user passwords (email, banking, etc.) that may have been stored on the machine. Investigate for persistence mechanisms (e.g., new scheduled tasks) and block the associated command-and-control IP address (194.38.20.224).
