Cities: Skylines

Late Monday evening, an outside actor pushed an update to the mod, which includes a .dll file which we believe is malicious.

If you have played using the affected version, please check your local files. If you have any malicious files installed, you will find them here; %localappdata%low\Colossal Order\Cities Skylines II.cache\Mods\mods_subscribed\ inside the folder 80095_13

Note that it is only specifically the 80095_13 folder that will contain malicious files; if you do not see this folder, you do not have the compromised version of the mod.

If you do locate this folder, use an antivirus or antimalware program to quarantine it and/or remove it from your system, and run a thorough scan of your drives.

As a precaution, we recommend changing your passwords.
