## Public findings

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

Package is advertised as a lightweight TOTP/HOTP library, but its package.json declares a postinstall hook (\`node lib/core.js\`) that runs a Windows credential stealer on install. The payload enumerates Windows Credential Manager entries matching \`MCL|\*|Xal\*\` via inline P/Invoke PowerShell (CredEnumerate/CredRead), reads launcher account JSON files under %APPDATA%\\.minecraft\\launcher\_accounts\*.json, extracts Microsoft Account refresh tokens (regex \`M.C...\`) and access tokens, and exchanges them at login.live.com/oauth20\_token.srf, Xbox Live, and minecraftservices endpoints to obtain session identifiers. It also builds a Chromium DPAPI decryption chain (PowerShell \`\[System.Security.Cryptography.ProtectedData\]::Unprotect\` against \`os\_crypt.encrypted\_key\` from Chrome's Local State, plus an AES-256-GCM decipher) to decrypt browser cookie/credential blobs. Harvested data is posted as JSON and multipart file uploads to a hardcoded Discord webhook whose URL is concealed as an XOR-0x3F byte array (\`\_W\`) decoded at runtime along with other sensitive strings (\`powershell\`, \`child\_process\`, \`ProtectedData\`, discord user-agent). An \`\_env()\` gate short-circuits on CI, during \`npm audit\`/\`npm pack\`, when %APPDATA%/USERPROFILE/USERNAME/COMPUTERNAME are missing, or when \`~/Documents\` is absent, so the payload only fires on real Windows developer hosts. The 2FA description is a cover story.
