There’s a (Spy)App for That
The proliferation of mobile phones and their accompanying app store ecosystems have made mobile applications an enticing target for malicious developers. Researchers at Lookout discovered the Igexin advertising library contained a backdoor, allowing Igexin to execute arbitrary code.
The advertising library was used by over 500 applications on the Google Play store which were downloaded over 100 million times. The affected applications allowed Igexin to surreptitiously steal call histories, GPS location, and other phone metadata.
In an age where there (apparently) needs to be an app for everything, developers are heavily relying on third party libraries to quickly publish an application. This approach of bolt-on development means there’s plenty of un-vetted code running on users’ devices.
The developers of the affected applications were likely unaware of the backdoor functionality hidden in the Igexin advertising library. In a different case, two malicious apps were spotted on the Google Play store which abuse the Accessibility features to install mobile malware.
Take the following steps to protect yourself:
- Avoid installing unnecessary applications
- Restrict the permissions granted to applications
- Keep your phone’s operating system up to date
- Be cautious with applications requesting accessibility permissions
