Summary
Malicious code in personio-pipeline-projen (npm)
Details

personio-pipeline-projen presents itself as an authorized dependency-confusion proof-of-concept; the evidence does not identify a copied public package. Its preinstall hook runs on install with node canary.js. The dependency-confusion probe encodes the installing machine's hostname and username, present CI-variable names, and root project and lifecycle identifiers in a DNS label under db2su65ptuma8gfn6ing8e7dx7wp55zit.oast.fun, and sends an HTTPS GET to hrcv3zo9m3z70yr91ssdz669c0ir6ju8.oastify.com. The npm account reaperhackbot256f published it on 2026-10-07 (UTC).

CWE
  • CWE-506 - The product contains code that appears to be malicious in nature.
