ESET , the pioneer of positive protection, released its white paper "The Rise of Android Ransomware". The credit report tracks the developing pattern of this especially insidious malware. Whether through encryption capabilities (as discovered by ESET in 2014 with Simplocker), with PIN locking capabilities (as LockerPin found by ESET in 2015) or simply lockscreen capability, this type of malware increasingly endangers Android users and continues in keeping our researchers hectic.

As the authors of the paper-- ESET scientists Robert Lipovsky, Lukas Stefanko and Gabriel Branisa-- conclude, ransomware is a growing issue for users of mobile phones. Lock-screen types and file-encrypting "crypto-ransomware", both which have actually been causing major financial and information losses for years, have actually made their way to the Android platform. Like other types of Android malware-- SMS trojans, for example-- ransomware risks have actually been developing over the past couple of years and malware writers have actually been adopting a number of the very same strategies that have actually shown to be reliable in regular desktop malware.

Both on Windows and on Android, lock-screens are nowadays generally of the "authorities ransomware" kind, aiming to frighten the victims into paying up after (falsely) charging them of harvesting prohibited material on their gadgets. As with the notorious Windows Cryptolocker ransomware family, crypto-ransomware on Android began utilizing strong cryptography, which meant that impacted users had no useful method of restoring the hijacked files. And since everyday information, such as images, for example, are now continued smartphones rather than PCs by a lot of individuals, the hazard of losing this data is now greater than ever.

One interesting observation that we have actually made is that the assaulters' center of focus is no more just Eastern European countries. A number of recent households, such as Android/Simplocker and Android/Lockerpin, for instance, have been targeting victims mostly in the USA.

The graph below programs the enhancing pattern in Android ransomware detections because April 2014, with the pattern reaching a peak of detections in August and September 2015, as recorded by ESET LiveGrid telemetry.

"With consumers continuing to switch from PCs to mobile, increasingly more important data is being kept on these devices that people bring around. For this reason, Android ransomware is becoming ever more worthwhile for aggressors," states Robert Lipovsky, ESET Researcher.

"For users of Android gadgets it's crucial to be knowledgeable about ransomware hazards and to take preventive measures along with having actually security solution installed. Among the most essential active measures to take are preventing unofficial app shops and having a mobile security app set up and kept up to this day. Additionally, it is essential to have a functional backup of all of crucial information from the gadget," includes Lipovsky.

"Explosive usage of the mobile technology and absence of security have actually made mobile phones such as smartphones and tablets incredibly vulnerable to exploitation and breaches by malicious cybercriminals, including information breaching, malware and spyware attacks and more.

"Addressing mobile security must be top priority for any organisation. Sound IT structure should be formulated to secure organisations from a number of unsafe cyber-attacks to offer solid protective guard must any security crisis happen," stated Mohamed Djenane, Security Specialist - ESET Middle East.
