Malware has been distributed through multiple maps on the Steam Workshop for Meccha Chameleon. An independent researcher identified the issue on July 24. Developers released a patch the following day while the game's official Discord server was hacked.
An independent researcher named Feint published a report on Medium describing how the map Laser Tag Neon opened a command prompt window and downloaded a script to install malware.
The map was removed after the report but new malicious maps appeared afterward. Developers lemorion_1224 stated that version 3.1.0 of the game fixed the vulnerability.
The official Discord server was compromised on July 25. A system engineer's PC became infected during the malware investigation and a hacker bypassed two-factor authentication to alter permissions and ban staff members.
The game itself remains unaffected. Developers contacted Discord Support and said they would create a new server if the original cannot be recovered.
