## Public findings

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

index.js, the package's main entry, runs at require() time with no user interaction. On load it spawns OS-native calculator processes via child\_process.exec ('calc.exe' on Windows, 'open -a Calculator' on macOS, 'gnome-calculator' on Linux) to demonstrate arbitrary code execution; writes a marker file to the user's Desktop (INSOMNIA\_RCE\_PROOF.txt); and serializes the full process.env object with JSON.stringify and emits it to the console, disclosing any tokens, API keys, and other secrets present in the environment of the host process (typically Insomnia on a developer machine). The source comments self-identify the module as a proof-of-concept remote code execution payload targeting Insomnia's plugin loader. The arbitrary-exec, filesystem write outside the package directory, and bulk environment enumeration all fire unconditionally at load.
