## Public findings

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

The package's declared main entry (index.js) unconditionally requires./\_init on load. \_init.js assembles hardcoded remote hosts from split string fragments (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev) and downloads a platform-specific binary payload via https.get. The bytes are written to /tmp or %TEMP% under a disguised filename (.cache\_\<hex\> on Unix, dotnet\_diag\_\<hex\>.exe on Windows), chmod'd to 0755, and spawned detached via /bin/sh -c or cmd.exe. If the HTTPS fetch fails, \_init.js falls back to a DNS TXT covert channel, resolving c.\<domain\> and 0..N.\<domain\> under tin.dl.well1.site / tina.dl.well1.site / ldr.dl.well1.site / win.dl.well1.site, base64-decoding and concatenating the TXT-record fragments into an executable payload. Identifiers such as 'child\_process' and 'chmodSync' are assembled from split fragments at runtime to evade string-based scanners. The package name resembles an internal Tinkoff npm namespace ('tinkoff-statist-browser-typed-client-sme.compliance.web.events'), consistent with a typosquat/dependency-confusion lure whose declared 'event bus' purpose is incompatible with downloading and executing an opaque native binary on require.
