## Public findings

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

Package name \`@solana-labs/ancor\` is a one-character typosquat of the legitimate \`@coral-xyz/anchor\` / \`@project-serum/anchor\` Solana framework, published under the \`@solana-labs\` scope to impersonate official Solana Labs tooling. \`package.json\` declares \`"postinstall": "node install.js"\`, which fires automatically on \`npm install\`. install.js reads host identifiers via \`os.hostname()\` and \`process.platform\`, invokes \`child\_process.execSync\`, issues outbound HTTP/HTTPS traffic (including a \`POST\` at line 113 and a \`curl\` shell-out at line 173), and references \`https://api.mainnet-beta.solana.com\` as cover traffic. The combination of (a) impersonating-scope name targeting a top-tier ecosystem package, (b) a postinstall lifecycle hook executing a script that reads host identity and shells out to network primitives, and (c) execSync of arbitrary commands during install constitutes an install-time host reconnaissance / command-execution payload against any developer or build system that installs this package.
