Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-13632/ (Markdown: https://insights.sbomify.com/MAL-2026-13632/index.md)","id":"MAL-2026-13632","markdown":"https://insights.sbomify.com/MAL-2026-13632/index.md","name":"MAL-2026-13632","record":{"aliases":["GHSA-m55q-8hc5-f46f"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On import, dist/index.mjs chmods 0755 and spawns the bundled Linux x86_64 binary dist/internal/calc-math.dat as a detached background process. The binary is a RedShell-style remote-access implant: it beacons to hardcoded C2 217.60.77.63, executes /bin/sh commands, drops and runs additional ELFs and shellcode fetched from the C2, offers SOCKS5 proxying and TCP port forwarding, installs systemd --user persistence (svc-update.service), and exfiltrates files via POST /api/extract-receive. Implant commands /ssh_keys, /creds, /dbfind, /clipboard, /env, and /dataextract harvest installer-side secrets (SSH private keys, stored credentials, clipboard, environment) and upload them to the same C2 through a chunked BIGEXTRACT upload routine. Package name, README, and inline comments describe the ELF as a 'native math accelerator' for calendar/streak math, but the pure-JS daymath.mjs never invokes the binary; the shipped SHA-256 'integrity check' (4537b118...3466) pins this specific implant, so it functions as anti-tamper for the payload rather than a security control.\n\nAny computer that has this package installed or running should be considered fully compromised.
