The DNA-Droid is tested against thousands of samples. In order to extract dynamic features, a fully automated Android sandbox is developed which is publicly available for researchers as a web service. This helps in detecting ransomware activity in early stages before the infection happens. Moreover, Sequence Alignment techniques are employed to profile ransomware families. The DNA-Droid utilizes novel features and deep neural network to achieve a set of features with high discriminative power between ransomware and benign samples. It benefits of a dynamic analysis layer as a complementary layer on top of a static analysis layer. In this paper, DNA-Droid, a two layer detection framework is proposed. ![]() Moreover, they are inadequate in detecting ransomware attack in early stages before infection happens. ![]() Current solutions produce low accuracy and high false positives in presence of obfuscation or benign cryptographic API usage. The main reason is that ransomware and generic malware characteristics are quite different. The number of ransomware attacks are increasing exponentially, while even state of art approaches terribly fail to safeguard mobile devices. Additionally, we also found a new self-propagation module that allows it to spread by sending SMS messages containing the shortened URL to all contacts on the compromised device.Ransomware has become one of the main cyber-threats for mobile platforms and in particular for Android. In case of this new Koler variant, the malicious Android application arrives via a shortened bit.ly URL to a Dropbox location and pretends to be an image file. If the unsuspecting user downloads and installs the package, it will lock the user's screen, displaying a fake FBI warning page (see below), accusing the user of viewing child pornography. Despite this fact, the mobile market is clearly one that ransomware operators would like to tap into and Koler is a step in that direction. It is believed to be the mobile extension of the Reveton ransomware family. Ransomware has been a profitable venture in the PC world with the likes of Crytolocker, but is a relative newcomer on mobile devices, at least in part due to file restrictions in mobile operating systems which limit the ability of apps to access the full file system. Android Koler is a family of ransomware that targets Android users by locking up their mobile devices and demanding a ransom. ![]()
