LinkPro Rootkit Uses eBPF and Magic TCP Packets to Hide

🔒 An AWS-hosted compromise revealed a new GNU/Linux rootkit dubbed LinkPro, discovered by Synacktiv. Attackers leveraged an exposed Jenkins server vulnerable to CVE-2024-23897 and deployed a malicious Docker image (kvlnt/vv) to Kubernetes clusters, delivering a VPN/proxy (vnt), a Rust downloader (vGet) and vShell backdoors. LinkPro relies on two eBPF modules—Hide and Knock—to conceal processes and activate via a magic TCP packet, with a user-space fallback via /etc/ld.so.preload when kernel support is missing.
