Europe’s DMA raises new security worries for mobile ecosystems

Help Net Security

A new report from the Center for Cybersecurity Policy and Law raises concerns about mobile security as the European Union's Digital Markets Act (DMA) takes effect. The DMA mandates that major platform providers allow third-party developers access to key software and hardware features for better interoperability. While this aims to foster competition, experts warn it could weaken the security controls that have traditionally protected mobile devices. As apps and services become more interconnected through these new regulations, there is a risk that vulnerabilities could be introduced, potentially exposing user data and device integrity. This shift could affect millions of users across various mobile ecosystems, raising urgent questions about how security will be maintained in a more open environment.
