Rootkit Malware Targets Linux Systems via Zero-Day Vulnerabilities

/ 1 min read

🔍 Advanced rootkit malware exploits zero-day vulnerabilities in Linux systems. Fortinet researchers have identified a sophisticated rootkit that leverages multiple zero-day vulnerabilities in enterprise appliances, enabling attackers to gain persistent control over compromised Linux systems. The malware, introduced via a crafted shell script, integrates deeply into the system through a kernel module and a user-space binary, allowing for remote command execution and network traffic hijacking. Key techniques include the use of a Netfilter hook to intercept packets and disguise itself as a legitimate process. FortiGuard emphasizes the need for robust patch management, monitoring, and incident response strategies to combat such complex cyber threats effectively.
