An investigation into the compromise of an Amazon Web Services (AWS)-hosted infrastructure has led to the discovery of a new GNU/Linux rootkit dubbed LinkPro , according to findings from Synacktiv. "This backdoor features functionalities relying on the installation of two eBPF [extended Berkeley Packet Filter] modules, on the one hand to conceal itself, and on the other hand to be remotely activated upon receiving a 'magic packet,'" security researcher Théo Letailleur said . The infection, per the French cybersecurity company, involved the attackers exploiting an exposed Jenkins server vulnerable to CVE-2024-23897 (CVSS score: 9.8) as the starting point, following which a malicious Docker Hub image named "kvlnt/vv" (now removed) was deployed on several Kubernetes clusters.
