Malicious apps in the Google Play store grew 388 percent from 2011 to 2013, while the number of malicious apps removed annually by Google has dropped from 60 percent in 2011 to 23 percent in 2013, new research said.
Apps for personalizing Android phones led all categories as most likely to be malicious. The most downloaded malicious app in 2013 was Talking Angela, according to the research by RiskIQ.
For this survey, RiskIQ only counted Android apps in the Google Play store as malicious if they are/contain spyware and (SMS) Trojans that:
• Collect and send GPS coordinates, contact lists, email addresses etc. to third parties
• Send SMS messages to premium-rate numbers
• Subscribe infected phones to premium services
• Record phone conversations and send them to attackers
• Take control over the infected phone
• Download other malware onto infected phones.
“The explosive growth of mobile apps has attracted a criminal element looking for new ways distribute malware that can be used to commit fraud, identity theft and steal confidential data,” said Elias Manousos, chief executive of RiskIQ.
“Malicious apps are an effective way to infect users since they often exploit the trust victims have in well known brands and companies they do business with like banks, insurance companies, healthcare providers and merchants. Our unique visibility directly into App Stores allows us to shine a light on this problem and prevent attackers from impersonating brands to exploit their customers,” Manousos said.
