A security flaw in the Unity game platform could allow unauthorized code execution in Android games, posing a risk to mobile cryptocurrency wallets. The vulnerability, present since 2017, primarily affects Android devices, with lesser impacts on Windows, macOS, and Linux. Unity is distributing fixes to partners, and a public guide is expected early next week. Google has advised developers to update their apps immediately, although no malicious apps exploiting the flaw have been detected on the Play Store. Users are encouraged to update Unity-based games, avoid third-party app stores, and keep crypto wallets separate from gaming devices to mitigate risks.
