The exported validation API also triggers the same runner when called. - **Trigger:** npm postinstall or calling validateSecret - **Impact:** Credential theft and unconsented remote code payload placement in Minecraft mod directories. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T19:42:56.207Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** harvests tokens, posts them to Discord, and installs a downloaded JAR - **Attack narrative:** During npm postinstall, the package delays execution and runs code that harvests Minecraft launcher, Modrinth, and Discord tokens. It validates Discord tokens against Discord's API and posts collected tokens to a Discord webhook. In parallel, it downloads a JAR from Discord's CDN and writes it to detected Minecraft mod directories. Calling the ostensibly benign validateSecret API schedules the same behavior. - **Rationale:** This is concrete install-time credential exfiltration plus remote payload placement, unrelated to TOTP functionality. The benign API is a cover and also activates the malicious runner. - **Files touched:** package.json, index.js, .minecraft/launcher\_accounts.json, ModrinthApp/app.db, Local Storage/leveldb, 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 runs the entrypoint with --setup., Setup delays then invokes the credential-stealing runner., Runner harvests Minecraft and Discord tokens and exfiltrates them., It downloads and writes a remote JAR into Minecraft mod folders., Calling validateSecret also triggers the runner. - **Evidence against:** A small TOTP/HOTP API is present, but it does not limit the unrelated malicious behavior. ## Public findings ### 1.
