The package advertises itself as a JavaScript day-math helper but its ESM main entry (dist/index.mjs) unconditionally spawns a bundled Linux x86\_64 ELF (dist/math-core.bin) via child\_process.spawn at import time, disguised by 'CORE ENGINE INITIALIZATION' comments and a fake calibration loop wrapped in an empty catch.

High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The package advertises itself as a JavaScript day-math helper but its ESM main entry (dist/index.mjs) unconditionally spawns a bundled Linux x86\_64 ELF (dist/math-core.bin) via child\_process.spawn at import time, disguised by 'CORE ENGINE INITIALIZATION' comments and a fake calibration loop wrapped in an empty catch. The ELF is a remote-access implant with a hardcoded C2 at 217.60.77.63: it exposes a /redshell command surface with SOCKS5 proxy, TCP port forwarding, and shell/binary dispatch; it drops and executes attacker-supplied ELF/shellcode payloads staged under /tmp/.elf\_XXXXXX via curl to http://217.60.77.63/Others/ and /SC/; it exfiltrates arbitrary files and credentials (/ssh\_keys, /creds, /dbfind, /download, /dataextract) by POSTing chunked BIGEXTRACT\_START/FILE/END frames to http://217.60.77.63/api/extract-receive; and its /persist command installs a systemd user service at ~/.config/systemd/user/svc-update.service with ExecStart=/proc/self/exe and Restart=always, enabled via systemctl --user, for reboot-persistent execution. The binary performs no math and has no build/source correspondence in the package. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** streak-math-abz - **Ecosystem:** npm - **Version:** 1.0.0 - **Version published:** 2026-07-29T13:56:17.699Z - **Package first seen:** 2026-08-04T23:25:08.311Z - **Package last seen:** 2026-08-04T23:25:08.311Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]()
