The exported validation API also triggers the collection routine. - **Trigger:** npm install; also a call to validateSecret. - **Impact:** Account-token theft and unauthorized modification of Minecraft mod directories. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T19:31:32.945Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** harvests and decrypts tokens, posts them externally, and drops a downloaded JAR. - **Attack narrative:** During npm installation, the postinstall entry invokes index.js with --setup. That path collects Minecraft and Discord/browser tokens, uses Windows DPAPI through PowerShell to decrypt protected data, and POSTs results to a Discord endpoint. It also downloads a JAR from Discord CDN and writes it to detected Minecraft mod folders. Calling the exported validateSecret function additionally schedules the same collection routine. - **Rationale:** This is concrete install-time credential exfiltration and payload deployment unrelated to a TOTP utility. The behavior is stealth-oriented and activated without user consent. - **Files touched:** package.json, index.js, APPDATA/.minecraft/launcher\_accounts.json, APPDATA/.minecraft/mods - **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 runs index.js with --setup., Install path POSTs collected data to a Discord webhook., Reads Minecraft, browser, and Discord token stores., Uses PowerShell DPAPI decryption for encrypted tokens., Downloads and writes a remote JAR into Minecraft mod folders., Public validateSecret also starts the collection routine. - **Evidence against:** TOTP helper functions exist, but do not constrain the malicious paths. ## Public findings ### 1.
