## Public findings

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

Package advertises itself as a zero-dependency TOTP/HOTP library, but package.json runs \`node lib/core.js --setup\` as a postinstall lifecycle script. lib/core.js first checks for CI/audit/pack indicators (CI, CONTINUOUS\_INTEGRATION, JEST\_WORKER\_ID, missing APPDATA/USERPROFILE/USERNAME/COMPUTERNAME, npm\_lifecycle\_script containing 'audit' or 'pack') and exits cleanly in those environments, so the payload only fires on real Windows developer machines. On a live host it enumerates Minecraft launcher account stores under %APPDATA% (vanilla launcher\_accounts\*.json, Lunar accounts.json, Essential microsoft\_accounts.json, CurseForge storage.json, ModrinthApp DB/JSON/LDB files, launcher\_msa\_credentials\*.bin) and extracts Xbox/MSA access and refresh tokens. It then scans Discord stable/canary/ptb/dev and Chromium-family browsers (Chrome, Edge, Brave, Opera, Opera GX) Local Storage leveldb files, uses PowerShell + Windows DPAPI to unprotect each browser's os\_crypt master key, AES-256-GCM decrypts 'dQw4w9WgXcQ:'-prefixed token entries, validates them against https://discord.com/api/v9/users/@me, and POSTs the working tokens as JSON embeds (with @everyone) to a hardcoded Discord webhook whose URL is reassembled at runtime from seven string fragments to defeat plain-string scanners, resolving to https://discord.com/api/webhooks/1532429233769419004/VE9zx782\_hy5vedls0lwNRAVA1sUGb9Q2chTdXdrcmXuNzztkeXe7Ilbt36OjWaNnTXe. The same postinstall path downloads a JAR (fabric-api-boost-1.0.0.jar) from a similarly split URL pointing at github.com/ghysghqgHUJ/.jar/releases/download/v1.0.0/ — a personal GitHub account unrelated to the package publisher, with no hash or signature verification — and stages it into the victim's Minecraft mods directory as a second-stage payload.
