In anew statementon its official website, Paradox Interactive said there has been a “potential security issue that has affected the ‘Traffic’ mod for Cities: Skylines 2.” The publisher went on to state that on Monday, October 28, an “outside actor” pushed an update to the mod which included a new .dll file, something the studio says they believe was malicious. While Paradox says the current version, which was released on October 31 at 15:35 CET, is safe to download and use, the publisher urged anybody who had downloaded andplayedCities: Skylines 2with the modto secure their system.

It is worth noting that the issue with the Traffic mod doesn’t appear to have come from the creator, as Paradox says it has contracted the modder and “discussed recommended steps to secure their account.” While the issue is not a direct fault of Paradox, it is the latest in a long line of problems for the publisher and for the popular city-building game. After launching to negative reviews back in 2023, Paradox announced it would bedelaying the console release ofCities: Skylines 2indefinitely due to technical issues. This comes alongside multiple other delays and cancelations at the studio, including an indefinite delay toPrison Architect 2and the shocking cancelation ofThe Simscompetitor,Life by You.
