Furthermore, the file represents a "wild west" of security. Unlike official games distributed via Steam, a random Wmmt6.7z file found on a forum or a torrent site is a prime vector for malware. The .7z format is excellent for compression, but it is also opaque; you cannot see what is inside until you open it. For every enthusiast looking for the thrill of driving a Nissan GT-R at 340 km/h, there is a malicious actor looking to hide a keylogger inside the game's launcher. The file is a digital gamble.

At first glance, it looks like a standard file. The ".7z" extension indicates a high-compression archive (similar to a .zip file), created by the 7-Zip software. The "Wmmt6" part promises the sixth installment of Bandai Namco's legendary highway racing arcade game.

But what exactly is inside this file? Is it the full PC port of WMMT6? A virus? A private server emulator? Or just a desperate hoax?
