## Public findings

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

The package advertises itself as a TOTP/2FA helper but its package.json postinstall spawns lib/core.js as a detached, stdio-ignored child of the node runtime, so the payload runs automatically on \`npm install\` and outlives npm exit. lib/core.js hides its strings behind an XOR 0x3F char-code decoder that reconstructs a hardcoded discord.com/api/webhooks/... URL, a DPAPI class name, powershell.exe, AppData paths, and cmd tokens at runtime. Before running, \_env() exits when CI, CONTINUOUS\_INTEGRATION, JEST\_WORKER\_ID or npm\_config\_global are set, when APPDATA/USERPROFILE/USERNAME/COMPUTERNAME are missing, when the lifecycle script name contains 'audit' or 'pack', or when %USERPROFILE%/Documents is absent, gating execution to real Windows user machines. On Windows the payload shells out to powershell.exe with an inline C\# Add-Type that P/Invokes advapi32 CredEnumerate/CredRead to dump 'MCL|\*|Xal.\*' entries from Windows Credential Manager, extracts Microsoft refresh tokens and JWT access tokens, and trades them via login.live.com, XBL, XSTS and api.minecraftservices.com to mint Minecraft session IDs. It additionally reads the Chromium Local State encrypted\_key, strips the DPAPI prefix, calls System.Security.Cryptography.ProtectedData::Unprotect through PowerShell to recover the browser master key, and AES-256-GCM-decrypts cookies and stored credentials. The collected material is POSTed as JSON and multipart uploads (tagged with the OS username and '@everyone') to the XOR-decoded Discord webhook endpoint, which is unrelated to the package's advertised TOTP purpose and is not caller-configurable.
