Bouncer is a new Google product the company describes as an “automated scanner” designed to automatically check all content uploaded to the Android Market for malicious code, like spyware, trojans and all the other DANGER WORDS associated with recent high-profile Android malware headlines.
There are no additional steps involved for users of apps or the app developers, with Google’s Bouncer simply going about it business, checking apps all by itself as soon as they hit the Market. Here’s a little idea of how it works:
…once an application is uploaded, the service immediately starts analyzing it for known malware, spyware and trojans. It also looks for behaviors that indicate an application might be misbehaving, and compares it against previously analyzed apps to detect possible red flags. We actually run every application on Google’s cloud infrastructure and simulate how it will run on an Android device to look for hidden, malicious behavior. We also analyze new developer accounts to help prevent malicious and repeat-offending developers from coming back.
