An app based on static analysis for android ransomware

摘要

Ransomware is the most threatening malware which expects payment at the stake of your personal files/folders. Ransomware has been found in Windows, IOS, Android and even in Linux too. And none of them was able to protect its users from its threat. Many detection techniques and analysis tools have been developed to detect ransomware virus. According to the Verizon named American company's report, ransomware hit financial services, healthcare and public sector the most. Verizon also found that small and medium-sized businesses are now the main target of cyber criminals. So, in this paper, we have provided an extension to static text analysis so as to make it powerful. Ransomware attack its users by either by either blocking the screen or by encrypting user data. We try and provide leverage to the user by providing hardware interaction that allows the users to uninstall harmful applications by pressing the power button multiple times. To overcome data encryption, we allow the user to select the directories that contain important data, and as soon as new file is added to any of these directories, we upload the file on an online server, thus enabling the user to maintain a safe copy of all important data.
