## Public findings

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

On require() of the package, index.js loads \_ext.js which downloads a platform-specific binary from runtime-assembled Cloudflare workers.dev hostnames (oob-worker.cf99-9b3.workers.dev, cf100-416, cf101-adf, cf103-070) with a DNS-TXT covert-channel fallback against subdomains of dl.well1.site (tin/ldr/win.dl.well1.site) that reassembles base64 chunks into executable bytes. The fetched payload is written to /var/tmp or %TEMP% under disguised names (.cache\_\<rand\> on Unix, dotnet\_diag\_\<rand\>.exe on Windows), chmod +x'd, and spawned detached via spawn("/bin/sh",\["-c",fp+" &"\],{detached:true}) or spawn("cmd",...). C2 hostnames are assembled at runtime via \["oob-work","er.cf103-07","0.workers.","dev"\].join("") to defeat static string search. The package presents itself as a base framework typings module and ships an unreferenced lib/telemetry.js plus DISABLE\_TELEMETRY/ANALYTICS\_OPT\_OUT/DO\_NOT\_TRACK opt-out env vars as cover; the DNS-TXT path carries an inline comment describing it as chunked transfer for environments blocking HTTPS.
