SophosLabs researchers see rise in cross-platform mobile malware
People are always looking to save time and money, and hopefully both, with technology. Businesses and consumers love smartphones and computers because they are massively multi-functional, super-fast and efficient. We’ve been doing this for a long time – the spork, that funny looking multi-purpose utensil, dates back to 1874!
More recently, mobile application developers have used cross-platform development tools to increase efficiency in churning out apps that work in all three of the major mobile operating systems – Android, iOS and Windows.
Malware authors are no different. At SophosLabs, we have seen an increase in malicious apps written with cross-platform development tools such as PhoneGap, Titanium, Unity, Xamarin and Cocos2d.
SophosLabs researchers William Lee and Xinran Wu explain in a new research paper – Cross-Platform Mobile Malware: Write Once, Run Everywhere – that security researchers will face greater challenges analyzing and detect these pieces of mobile malware, as cybercriminals increasingly make use of multi-platform tools to hide their malicious code.
Their research demonstrates that malware authors are using cross-platform development tools “to hide their malicious code in HTML files or specific containers loaded by cross-platform frameworks instead of the platform’s native binaries.”
This fascinating research paper (presented earlier this month at the Virus Bulletin International Conference) explores in depth the feasibility of new cross-platform mobile malware and examines the package structures of these malware.
Finally, our researchers suggest a solution for identifying an application’s framework type and writing detection signatures for malware based on those frameworks.
