## Public findings

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

The package presents itself as a Tinkoff SDK but ships no legitimate functionality. On require(), index.js loads \_shim.js, which selects a platform-specific payload path, downloads a binary over HTTPS from hardcoded, string-split Cloudflare Workers subdomains (oob-worker.cf1030-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev), with a DNS-TXT fallback across tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, and win.dl.well1.site. The fetched bytes are written to /var/tmp or %TEMP% under disguised names such as.cache\_\<hex\> and dotnet\_diag\_\<hex\>.exe, chmod 0755'd, and spawned detached via /bin/sh -c or cmd. Hostnames are assembled from split fragments at runtime to evade string scanning.
