## Public findings

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

On require() of tinkoff-boxy-mobile-separator, index.js loads \_init.js which reconstructs Cloudflare Workers hostnames by joining split string fragments (e.g. \['oob-worker.cf101-adf.worker','s.','de','v'\].join('')), downloads a platform-specific opaque binary via https.get, writes it to /var/tmp or %TEMP% under a randomized hidden name (dotnet\_diag\_\*), chmods it 0755, and spawns it detached via spawn('/bin/sh',\['-c',fp+' &'\]) or spawn('cmd',...). A DNS-TXT covert channel (c.\<domain\> for chunk count, N.\<domain\> for base64-encoded chunks reassembled with Buffer.from(parts.join(''),'base64')) provides a fallback payload retrieval mechanism. No hash or signature verification is performed on the fetched executable. A second, structurally identical dropper is bundled at lib/telemetry.js (not reached from the main require graph but present in the tarball). The package name impersonates the Tinkoff namespace; there is no legitimate SDK behavior in the shipped code.
