Calling validateSecret also initiates the same routine. - **Trigger:** npm install; additionally, calling validateSecret after importing the package - **Impact:** Account-token theft and unconsented remote code/payload placement in user game directories. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T21:04:52.906Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** credential theft, webhook exfiltration, and dropped JAR persistence - **Attack narrative:** During postinstall, the package delays execution, collects Minecraft and Discord tokens from local application data, validates Discord tokens with Discord's API, and posts results to an obfuscated webhook. It also downloads a JAR and writes it to detected Minecraft mod folders. The same execution is scheduled by the exported validateSecret function. - **Rationale:** The package's advertised TOTP code is coupled to concrete credential theft, remote exfiltration, and unsolicited payload installation. These behaviors execute automatically at install time and are unrelated to its stated purpose. - **Files touched:** index.js, package.json, APPDATA/.minecraft/launcher\_accounts.json, APPDATA/\*/Local Storage/leveldb, LOCALAPPDATA/Google/Chrome/User Data/Default/Local Storage/leveldb, APPDATA/.minecraft/mods/optimized-renderer-1.0.0.jar - **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 executes index.js with --setup., Obfuscated URL is used as an HTTPS POST destination., Reads Minecraft launcher and client access tokens., Extracts and validates Discord tokens, then sends them remotely., Downloads a JAR and writes it into discovered Minecraft mods folders., Public validateSecret triggers the harvesting routine after import. - **Evidence against:** TOTP/HOTP helpers are present, but do not constrain the unrelated malicious routines. ## Public findings ### 1.
