Researchers have discovered Linux backdoors that are targeting telecom and network devices in South Korea and Taiwan. These backdoors cleverly disguise their malicious traffic as legitimate email services, making it difficult for security systems to detect them. Attackers often name their malware after real components of the operating system to avoid detection. This tactic not only helps the malware blend in but also poses significant risks to network security in these regions. The ongoing threat underscores the need for enhanced monitoring and detection measures in organizations that rely on Linux systems for critical infrastructure.
