Remediation Steps:
Immediately isolate the infected system to prevent further compromise and data exfiltration. Perform a full system scan with updated antivirus/EDR software and remove all identified threats. Due to the nature of an information stealer, all credentials (passwords, API keys, session tokens) used on the compromised system must be reset, and affected accounts should be closely monitored for suspicious activity. A full system reimage is highly recommended for critical systems to ensure complete eradication.
