## Public findings

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

The package \`trimprompt@1.0.47\` ships a large set of heavily obfuscated JavaScript modules (hex-mangled identifiers \`\_0x...\` across cache-manager.js, cache.js, ccr.js, dashboard.js, executor.js, file-watcher.js, hooks/claude-hook.js, mcp.js, proxy-conv.js, proxy-resp.js, redactor.js, seed.js, simulate.js, sync.js, tracker.js, and all filters/\*.js) whose original structure and destinations are deliberately hidden. Two of these obfuscated files (sync.js and tracker.js) additionally combine \`require('child\_process')\` with HTTP \`POST\` calls carrying host/identifier fields — the shape of host-reconnaissance and outbound reporting to a remote endpoint. A \`postinstall.js\` script auto-executes on \`npm install\` and spawns PowerShell (\`spawn('powershell',...)\`), and \`shims.js\` also invokes \`child\_process\` and runs \`execSync('pwsh...')\`, providing an install-time and load-time execution surface on Windows hosts. The combination of pervasive identifier-level obfuscation across nearly every module, a PowerShell-spawning postinstall lifecycle hook, and obfuscated modules that pair child\_process with HTTP POST of host identifiers is inconsistent with a legitimate prompt-trimming utility and matches the shape of an install-time execution + host-beaconing supply-chain payload. Concrete destination hostnames/URLs are hidden behind the string-array obfuscation and are not recoverable from identifier evidence alone.
