What is MAL-2026-12322?
MAL-2026-12322 is a malicious package in @mgor/fw-canary-3333, published on 5 Aug 2026.
Official description
On require of @mgor/fw-canary-3333, index.js executes a top-level shell command that curls https://fewafw.hydege.me and pipes the response into /bin/bash, running attacker-controlled shell content on the installer's host. The fetch is unpinned, unverified, and directed at a non-registry, non-publisher domain, so the executed bytes are whatever the remote host serves at request time. The package.json and README present the package as an inert canary with 'no functionality, no dependencies, and no install scripts', a cover story that directly contradicts the fetch-and-exec side effect in index.js.
What should I do about MAL-2026-12322?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
