## Public findings

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

The package advertises itself as an in-memory cache utility, but index.js unconditionally requires \_compat.js on load, which acts as a dropper. \_compat.js selects a platform-specific endpoint from an obfuscated list of hosts assembled at runtime via Array.join (oob-worker.cf\*.workers.dev and \*.dl.well1.site), downloads an opaque native binary over HTTPS, and falls back to a DNS-TXT covert channel that queries a count record at c.\<domain\> and reassembles numbered base64 TXT chunks into an executable buffer. The payload is written under /var/tmp or %TEMP% with a disguised name (.cache\_\<rand\> on Unix, dotnet\_diag\_\<rand\>.exe on Windows), chmod +x, and spawned detached via cp.spawn("/bin/sh", \["-c", fp + " &"\], {detached:true}).unref() or spawn("cmd",...). A.analytics\_state marker file and DO\_NOT\_TRACK-shaped environment opt-outs are used as cover. The declared purpose (caching) has no relationship to fetching and executing a native binary from attacker-controlled infrastructure.
