This is a public service announcement for all BlazBlue: Central Fiction. An exploit has been discovered for the 2016 2D fighter from Arc System Works (makers of both the BlazBlue and Guilty Gear franchises) that makes lobby-hosting computers vulnerable.
According to multiple warnings being posted on Discord and social media, this exploit affects those hosting games in Steam lobby servers. The exploit allows someone who connects to your lobby to send a payload that downloads and executes files on the host computer. This means a hacker could freely install malware to the host computer, letting them steal passwords or provide them remote access.
The payload disguises itself as "iDmacDrv32.dll," a dll file that's already present in a base install of BlazBlue: Central Fiction. Hosting lobbies makes the host vulnerable, so the best way to stay safe is to keep your lobbies to invite only. It’s also recommended that you ensure your antivirus software is up to date and running.
If someone joins your game and it crashes, you can get rid of the payload by verifying the game files. Just go into your Steam library, right-click BlazBlue: Central Fiction, then click “properties,” “local files,” and then “verify the integrity of game files.”
However, the time it takes to verify the files might already give hackers enough time to install malware, so be sure to have your antivirus software running as well. Arc System Works has already been notified of the vulnerability, so expect a patch to fix this exploit shortly.
In a less harmful but far stranger hack, GTA Online players are sometimes logging into servers only to find the entire map is folding in on itself. Like Dr. Strange and the Multiverse of Madness, the skybox is actually just more of the city flipped upside-down. It’s trippy, but this random act of online vandalism also makes aerial traversal somewhat more difficult than usual thanks to all the floating debris.
