TrustGo Mobile Inc., a mobile security company today released its Q4 Mobile Mayhem Report. The report which reveals the status and trends in mobile app security highlighted app-based threats as a major problem in the Android system.

After doing extensive research from the collected data (information on 2.27 million apps found on 187 marketplaces worldwide), the organization analyzed all new apps uploaded to monitored marketplaces via TrustGo’s Secure App Finder Engine (SAFE) and classified each app into one of the below mentioned categories:

  1. Certified (Safe to download)
  2. Malicious (Containing a virus, Trojan, spyware, etc.)
  3. High Risk (Containing code that leverages granted permissions to create a security risk)
  4. Low Risk/Noisy (Has potential to annoy users with excessive notifications or advertisements)

Xuyang Li, founder and CEO of TrustGo believes malware continues to be a problem around the world, hence, different categories for apps to help you distinguish between ‘High Risk’ apps and ‘Safe’ apps. It is ‘High Risk’ apps in which the growth of malicious activity is most observed.
