Shedun
Shedun is a family of malware software (also known as Kemoge, Shiftybug and Shuanet[1][2][3]) targeting the Android (operating system) first identified in late 2015 by mobile security company Lookout (company), affecting roughly 20,000[4] popular Android applications.[3][5][6][7][8][9]
Avira Protection Labs stated that Shedun family malware is detected to cause approximately 1500-2000 infections per day.[10] All three variants of the virus are known to share roughly ~80% of the same source code.[11][12]
The malware's primary attack vector is repackaging legitimate Android applications (e.g. Facebook, Twitter, WhatsApp, Candy Crush, Google Now, Snapchat[13])[4][14][15] with adware included, the app which remains functional is then released to a third party app store;[16] once downloaded, the application generates revenue by serving ads (estimated to amount to $2 US per installation[15]), most users cannot get rid of the virus without getting a new device, as the only other way to get rid of the malware is to root affected devices and re-flash a custom ROM.[5][17][18]
In addition, Shedun-type malware has been detected pre-installed on 26 different types[19] of Chinese Android-based hardware such as Smartphones and Tablet computers.[20][21][22][23] [24][25][26][27][28][29][30][31][32][33][34]
Shedun-family malware is known for auto-rooting the Android OS [14][35] using well-known exploits like ExynosAbuse, Memexploit und Framaroot [36] (causing a potential privilege escalation[15][37][38])[39] and for serving trojanized adware and install themselves within the system partition of the operating system, so that not even a factory reset can remove the malware from infected devices.[40][41]
Shedun malware is known for targeting the Android Accessibility Service,[2][40][42][43][44][45][46] as well as for downloading and installing arbitrary applications[47] (usually adware) without permission,[3] it is classified as "aggressive adware" for installing potentially unwanted program [48][49][50] applications and serving ads.[51]
As of April 2016, Shedun malware is, by most security researchers, considered to be next to impossible to remove entirely.[52][53][54][55][56][57]
Avira Security researcher Pavel Ponomariov, specialized in Android malware detection tools, mobile threats detection and mobile malware detection automation research,[58] has published an in-depth analysis of the computer virus.[10]
