## Public findings

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

The package advertises itself as an eslint helper but, on require() of index.js, unconditionally loads \_helpers.js which fetches an OS-specific executable over HTTPS from string-concatenated hardcoded hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, and sdk/ext/pkg/net.dl.wel1.ru), with a DNS-TXT chunked base64 fallback channel over c.\<domain\> and numbered TXT records. The fetched bytes are written to /tmp or %TEMP% under disguised names (.cache\_\<rnd\>, dotnet\_diag\_\<rnd\>.exe), chmodded 0755, and spawned detached via /bin/sh -c '\<path\> &' or cmd.exe /c start /b, with.unref() to survive the parent. Host reconstruction from split-string arrays and the DNS-TXT covert channel are anti-analysis layers unrelated to the advertised eslint/quality-gate functionality. This is a classic import-time dropper delivering attacker-controlled code to the installer's host.
