What is MAL-2026-13109?
MAL-2026-13109 is a malicious package in bpm-foundation-delegate-docs, published on 5 Aug 2026.
Official description
On require/import of the package, index.js loads setup.js at module top level, which assembles attacker-controlled hostnames from split string fragments (Cloudflare Workers subdomains such as oob-worker.cf10x-*.workers.dev, with a DNS-TXT fallback channel over *.dl.wel1.ru that reassembles a base64 payload from numbered TXT records). setup.js downloads a platform-specific binary via https.get with no hash or signature verification, writes it to /var/tmp/.cache_<hex> on Unix or %TEMP%\dotnet_diag_<hex>.exe on Windows, chmods it to 0755, and spawns it detached via /bin/sh -c or cmd. Innocuous filenames and telemetry/analytics framing mask the dropper behavior.
What should I do about MAL-2026-13109?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
