Kaspersky Lab has published its IT Threat Evolution Report for Q2 2013, which analyses IT security incidents and trends. According to the report, mobile malware was the most significant statistical category for the second quarter, in both quantity and complexity. Not only are cybercriminals developing more malware targeting mobile platforms, they’re also advancing the programs’ capabilities and behaviours. In addition to mobile malware, cybercriminals focused heavily on implementing campaigns designed for illegal bitcoin mining and theft as the digital currency’s value rapidly increased during the second quarter. With mobile malware, the malicious code is modified to infect legitimate mobile applications. The common procedure for cybercriminals is to download legitimate applications and modify them by adding the malicious code. Cybercriminals then redistribute the modified” and now malicious – applications to sites where they can be downloaded by users, such as third-party app stores. Malicious code samples are being inserted into the modified applications using cloud-based technologies, heuristics and antivirus signatures. While the most prevalent mobile malware category has traditionally been SMS-Trojans, this trend declined in the second quarter as Trojans designed for mobile platforms started to incorporate more capabilities and flexibility. In the second quarter, Backdoor Trojans had the largest amount of modifications added. In terms of mobile malware capabilities, cybercriminals are now adding obfuscation techniques to evade analysis while frequently compiling programs that carry multiple payloads, which can generate money using several types of illegal business models. New variants can also extract larger amounts of stolen data from users’ devices while also being able to download and install additional malware onto infected devices.
