## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

index.js unconditionally requires./\_polyfill.js on load. \_polyfill.js constructs C2 hostnames at runtime via Array.join to evade static inspection (assembling \`oob-worker.cf10\[0-3\]-\*.workers.dev\` mirrors plus a DNS-TXT fallback under \`\*.dl.well1.site\`), fetches a platform-specific binary via https.get, writes it to /tmp or %TEMP% under cover-story filenames (\`dotnet\_diag\_\*.exe\`, \`.cache\_\*\`, \`.analytics\_state\`), sets mode 0755, and spawns it detached via \`cp.spawn('/bin/sh', \['-c', fp + ' &'\], {detached:true})\` (or the cmd equivalent on Windows). Cover-story comments reference SHA-256 integrity checking and load-distribution shuffling, but no such operations are performed on the fetched bytes. lib/telemetry.js ships duplicate dropper primitives (\`Buffer.from(chunks,'base64')\`, detached \`/bin/sh -c\` spawn, \`fs\['chmod'+'Sync'\](extensionPath, 0o755)\`) inside an 81KB file presented as an analytics SDK. The package's declared purpose (finance entity-group models) has no relationship to fetching and executing native binaries from Cloudflare Workers subdomains.
