Malicious code in bender-rspack-config (npm)
Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (3a6997cea54ae81d1addcb41ddac29e94923dfa1042265253c555cb4945ad5b4) package.json declares a preinstall lifecycle script that runs `wget` against a hardcoded webhook.site URL, embedding `$(whoami)`, `$(pwd)`, and `$(hostname)` as query-string parameters. The request fires automatically on `npm install`, transmitting the installer's username, working-directory path, and hostname to an author-controlled collector at webhook.site/9d385aa8-875e-48b6-938c-6c0f5a0e8319/. The behavior is self-labeled as a dependency-confusion proof of concept, but the shipped code is a functioning identity-beacon regardless of framing. ## Source: ossf-package-analysis (159730c04aeb50c0e832685be81c3f332d8692bf4a9f1a419c7223dbe5059491) The OpenSSF Package Analysis project identified 'bender-rspack-config' @ 1.0.0 (npm) as malicious.
