Malicious code in supplyhub (npm)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

The npm package `supplyhub` is a credential / SSH-key stealer. Its `package.json` declares a `postinstall` lifecycle hook (`postinstall: node postinstall.js`) that executes automatically on `npm install`, before the package is ever imported. `postinstall.js` uses `fs.readFileSync` to read the user's SSH private key (`~/.ssh/id_rsa`) and the process environment (`/proc/self/environ` — where CI/cloud tokens and npm tokens live), and gathers account/host identity via `os.userInfo()`; it also references `/etc/passwd`. The collected data is exfiltrated by HTTP POST to a hard-coded webhook.site dead-drop: `https://webhook.site/3c9418b3-cacd-403d-b42e-e9e4a9508fe3`. Only version 1.0.2 is malicious: version 1.0.0 (held in the codelake corpus) is clean — the exfiltration code was introduced in the 1.0.2 release (a trust-then-poison pattern). Any workstation or CI runner that installs [email protected] (directly or transitively) hands its SSH key and environment secrets to the operator. --- _-= Per source details.

The package.json description self-labels this as a dependency-confusion PoC targeting the 'Travix supplyhub' name, but the tarball is published to public npm and will execute the install-time beacon against any installer that resolves this name, including unrelated users who typo or whose internal builds dependency-confuse into it.
