Remediation Steps:
Immediately isolate the infected Linux system and conduct a comprehensive forensic analysis to determine the full scope of compromise and its interactions with Windows environments. Perform full scans on all connected Windows endpoints, implement extracted Indicators of Compromise (IOCs) across the network, reset any potentially compromised credentials, and ensure all systems are fully patched.
