Calling validateSecret also starts the same collector. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-22T19:30:50.627Z - **Finished:** 2026-08-22T19:31:27.734Z - **Download time:** 256 ms - **Static scan time:** 69 ms - **AI review time:** 36782 ms - **Total time:** 37107 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm install, the package harvests launcher and Discord/browser credentials, exfiltrates them, and drops a remotely downloaded JAR into detected Minecraft mod folders. Calling validateSecret also starts the same collector. - **Trigger:** npm postinstall; also a runtime call to validateSecret - **Impact:** Account-token compromise and unconsented execution of an attacker-supplied Minecraft mod. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T19:31:27.734Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** credential theft, webhook exfiltration, and remote JAR drop - **Attack narrative:** The postinstall launches a delayed collector that reads Minecraft account tokens and Discord/browser token stores, decrypting protected values through PowerShell DPAPI. It posts results to an obfuscated Discord webhook, then downloads a JAR from Discord CDN and writes it into detected Minecraft mod directories. The exported validation API separately schedules this chain, so importing and using the advertised utility can trigger it. - **Rationale:** This is a concrete install-time credential-stealing and payload-dropping chain unrelated to TOTP functionality. The delayed, swallowed-error postinstall increases stealth. - **Files touched:** %APPDATA%/.minecraft/launcher\_accounts.json, %APPDATA%/ModrinthApp/app.db, Discord and Chromium Local Storage leveldb files, Minecraft and Modrinth mods directories, temporary .tu-1432.lock - **Network endpoints:** discord.com, cdn.discordapp.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall invokes index.js with --setup., Install path collects Minecraft and Discord credentials., It decrypts browser token material through Windows DPAPI., Collected tokens are posted to an obfuscated Discord webhook., It downloads and writes a JAR into Minecraft mod folders., Library use of validateSecret also schedules the collector. - **Evidence against:** The exported TOTP functions implement plausible token utilities, but do not constrain the hidden collector. ## Public findings ### 1.
