Warning after Cities: Skylines mod spreads malware
Valve has banned a modder for including malicious code in Cities: Skylines mods, and although no keyloggers were found Valve still recommends unsubscribing from the offending mods immediately.
The modder went by the aliases Holy Water and Chaos, and the malicious mods were simply copies of popular mods that had been modified and reuploaded as original works.
- Harmony (redesigned) needs to be removed
- Network Extensions 3 removal can break save files
- Alternate mods may be able to “rescue cities” from mod
- Malicious code was obscured to prevent discovery
Mod PSA: “We recommend in the strongest possible terms that you unsubscribe from all items published by this author and do not subscribe, download, or install any mods, from any source, that may be published by this individual in future,” reads a statement on Reddit.
Unsubscribe: A user called Crete put together a Steam Workshop collection named No Chaos to help users quickly identify the malicious mods and unsubscribe from them.
