The binary is a remote-shell implant (strings include \"REDSHELL\", \"SECURE_BEACON\", \"RedShell commands:\", \"/redshell socks start <port>\") that connects to a hardcoded C2 at 217.60.77.63 and awaits operator commands. Once running, the implant exposes commands to (a) download and execute additional ELF binaries and raw shellcode fetched from http://<c2>/Others/... and http://<c2>/SC/... into /tmp or via memfd_create (syscall 319), (b) harvest SSH keys, credentials, database files, clipboard contents, and arbitrary files, exfiltrating them over a chunked HTTP POST channel to /api/extract-receive with BIGEXTRACT_START/END framing, and (c) install systemd user-unit persistence by writing ~/.config/systemd/user/svc-update.service (Description=\"System Update Service\", Restart=always, ExecStart=/proc/self/exe) and running systemctl --user daemon-reload && enable --now. The ELF is labeled a \"Native math accelerator\" in the loader, but contains no math functionality — its entire string table is red-team beacon / SOCKS5 proxy / port-forward / shellcode-injection tooling. Importing this package hands remote command execution, credential access, and reboot-persistent access on the installer's host to the C2 operator.\n\n## Source: ghsa-malware (c703ba5a38df97a92435243475d2439422432b7fa02025b4e41ae0308e1dde9b)\nAny computer that has this package installed or running should be considered fully compromised.
