Malicious code in log-sink-testmetest (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.0.1`

log-sink-testmetest 1.0.1 ships the credential stealer of data-pipeline-testmetest 2.0.1 and runs it on `npm install` without an install script: its `binding.gyp` source `<!(env node index.js >/dev/null 2>&1; echo stub.c)` makes node-gyp run `index.js`, which decrypts `data.bin` and pipes it into Bun. The payload is identical to the one in event-emitter-testmetest 5.0.0. Published by npm account `testnewtestme2` on 2026-10-21; 1.0.0 is empty.
