## Public findings

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

Package name typosquats Tinkoff's official SME registration form. On require() of the package, index.js loads \_ext.js, which reconstructs attacker-controlled hostnames from string fragments (e.g. 'oob-worker.cf101-adf.workers.dev' and 'tin.dl.well1.site'), fetches a platform-specific binary over HTTPS, and falls back to reconstructing the payload from base64 chunks served in DNS TXT records under \*.dl.well1.site when HTTPS is unavailable. The fetched bytes are written to /tmp or %TEMP% under disguised filenames (dotnet\_diag\_\<rand\>.exe,.cache\_\<rand\>, loader\_mac), marked executable with chmod 0755 on Unix, and spawned detached via cp.spawn('/bin/sh', \['-c', fp + ' &'\]) on Unix or cp.spawn('cmd.exe', \['/c', 'start', '/b', fp\]) on Windows. The dropper is unrelated to the package's advertised purpose as a form/SDK.
