## Source: amazon-inspector (dc1ebadea2eb63a0fc7cf7446e36a589c5b87fc7d28e68b68145b98577107ebb) npm package @rutxploit-sec/subsplash-canny declares a preinstall lifecycle script that runs `node -e` inline code reading `os.hostname()` and `os.userInfo().username` and issuing an HTTP GET to http://127.0.0.1:8099/ with those values as query parameters, plus a package identifier. The package.json description and README self-describe the artifact as a dependency-confusion proof-of-concept impersonating the private scoped name `@subsplash/canny`. Installing this package on any machine automatically executes the beacon at install time and transmits the installer's hostname and OS username to the configured endpoint. The current destination is loopback (127.0.0.1:8099), which limits real-world reach in this specific tarball, but the mechanism — arbitrary code execution and identity collection on `npm install` — is fully wired and would function identically against any remote endpoint. --- Credit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/df8912ac853d808526d73c577abd0cdfa8d704f1/osv/malicious/npm/@rutxploit-sec/subsplash
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
