Remediation Steps:
Immediately isolate the affected Linux system or device from the network. Conduct a thorough scan using robust security software. Reset all user credentials, particularly default or weak ones, and ensure all system and application patches are up-to-date. Implement strong firewall rules and monitor network traffic for any suspicious activity indicative of botnet communication.
