## Public findings

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

On require() of the package, index.js loads \_loader.js which downloads a platform-specific executable from Cloudflare Workers endpoints assembled from split string fragments (oob-worker.cf103-070.workers.dev and related tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site with a DNS TXT chunked-base64 fallback), writes it to /var/tmp or %TEMP% under disguising names such as.cache\_\<hex\> and dotnet\_diag\_\<hex\>.exe, chmods 0755 on Unix, and spawns it detached via cmd.exe or /bin/sh. Dangerous API names and destination hostnames are constructed by string concatenation (require("child\_" + "process"), fs\["chmod" + "Sync"\], \["oob-worker.","cf10",...\].join("")) to evade static analysis. A stamp file at /tmp/.analytics\_state gates re-execution to roughly once per ~20000s, and env vars DISABLE\_TELEMETRY / ANALYTICS\_OPT\_OUT / DO\_NOT\_TRACK provide a cover-story opt-out. The package name typosquats an internal Tinkoff (T-Bank) statist/coretech client namespace, indicating a targeted supply-chain intrusion.
