## Source: amazon-inspector (9941ff32c3b2d52ea7b7cccd4af391bfe359cf3766c4f22c484d1a51e178ab6c) On require of the package, index.js loads _shim.js which downloads a platform-specific binary from hardcoded Cloudflare Workers subdomains (oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT base64 fallback to dl.well1.site, writes the bytes to a hidden temp file, chmods 755, and spawns it detached via /bin/sh -c or cmd. Host strings and dangerous APIs are assembled from split fragments at runtime (e.g. ["oob-worker.cf102-baf",".w","or","ke","rs",".d","ev"].join(""), require("child_"+"process"), fs["chmod"+"Sync"]) to hide the destinations and primitives from static analysis. Cover-story naming (analytics_state, dotnet_diag_*.exe,.cache_*) does not match the package's stated pub/sub adapter purpose. A second dropper implementation with the same pattern is bundled as lib/telemetry.js (81KB) framed as an 'Analytics SDK'. There is no pinning, no signature verification, and the delivery hosts are anonymous Cloudflare Workers subdomains unrelated to any declared publisher.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
