## Public findings

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

Package name impersonates the popular chai-as-promised assertion library, but its package.json description and keywords are copied from pino and the code is unrelated to chai. The package's main entry exports a middleware factory that spawns lib/caller.js as a detached node child process. lib/caller.js base64-decodes a hardcoded URL pointing at api.jsonstorage.net (a mutable third-party JSON storage service), GETs the JSON document, extracts the \`cookie\` field, and executes its contents via \`new Function.constructor('require', s)(require)\` with full access to \`require\`. The C2 URL and request headers are stored as base64 strings inside a locally redefined \`process\` object that shadows the real process global, then decoded with \`atob\` at runtime. Any consumer who installs and invokes the exported middleware triggers arbitrary attacker-controlled code execution; the attacker can rotate the payload served by the JSON storage endpoint at will.
