There are numerous malware detection and antivirus apps for mobile devices running the Android operating system. However, a team in China introduces a new approach that can detect malicious activity at the source code level. They provide details in the International Journal of Information and Computer Security.

Junaid Akram, Majid Mumtaz, Gul Jabeen, and Ping Luo of The Key State Laboratory of Information Security at Tsinghua University, explain how their approach is not only scalable but offers self-optimisation of the signature set as it detects malicious apps by reading their source code. The team has developed a prototype of their software, DroidMD.

They have tested it against almost 30000 applications of which 3,670 are already identified as malware. It is reliable because it analyzes only the code and has a high detection accuracy of 95.5%.

"In our future work, we will make DroidMD more resilient for minimizing the obfuscation and improving its run time. Meanwhile, we will extend it for other programming languages to detect malware or malicious code fragments from source code to overcome security threats," the team writes.
