Abstract:

With the popularity of smart devices such as smartphones and pads, the attack of Android ransomware is becoming increasingly serious. Compared with other malicious software, ransomware is widely favored by hackers because of hard restoration and the directness of obtaining benefits, which also brings serious spiritual and property damage to users. To protect our smart devices from ransomware and reduce threats and losses, researchers conduct a lot of research on Android ransomware and propose many practical detection schemes. This paper first summarizes the characteristics of Android ransomware, and then summarizes the existing research work on detecting and safeguarding against ransomware on the Android platform and makes a comprehensive analysis and comparison on them. Finally, we point out the remaining problems of these solutions, put forward corresponding suggestions and discuss future research directions.

Key words: ransomware, Android, detection, safeguard
