App Store-Aided Mobile Attacks
Trailrunner7 sends along a ThreatPost.com piece that begins "The pace of innovation on mobile phones and other smart wireless devices has accelerated greatly in the last few years. ... But now the attackers are beginning to outstrip the good guys on mobile platforms, developing innovative new attacks and methods for stealing data that rival anything seen on the desktop, experts say. This particular attack vector — introducing malicious or Trojaned applications into mobile app stores — has the potential to become a very serious problem, researchers say. Tyler Shields, a security researcher at Veracode who developed a proof-of-concept spyware application for the BlackBerry earlier this year, said that the way app stores are set up and their relative lack of safeguards makes them soft targets for attackers. ... 'There are extremely technical approaches like the OS attacks, but that stuff is much harder to do,' Shields said. 'From the attacker's standpoint, it's too much effort when you can just drop something into the app store. It comes down to effort versus reward. The spyware Trojan approach will be the future of crime. Why spend time popping boxes when you can get the users to own the boxes themselves? If you couple that with custom Trojans and the research I've done, it's super scary.'"
here are at least 185,000 third-party applications officially available on the App Store
If wonder how many there are if you exclude things that should not need an app - e.g. newspaper apps that provide the same content you can see on the website.
