Red Menshen (Earth Bluecrow), a China-nexus APT group, has deployed an advanced variant of the BPFDoor kernel-level backdoor against telecom backbone infrastructure across the Middle East and Asia, with government entities assessed as the primary collection target. The implant operates below the visibility of standard security tools, embedding activation triggers inside HTTPS traffic and conducting lateral movement over ICMP, making it invisible to userspace monitoring tools (ps, netstat) but detectable via kernel-level auditing (bpftool, eBPF probes). New support for SCTP, a telecom signaling protocol, elevates the threat beyond network espionage to potential subscriber-level surveillance, with serious implications for any organization operating or relying on regional telecom infrastructure.
