Hackers Tweak Tactics to Maximize Profits, Send Android Malware Soaring


Malware on Google’s (GOOG)  Android grew 35% in the second quarter, the fastest pace since early 2012, as  hackers infiltrated systems using malicious apps and SMS stealing and tweaked  tactics to maximize profits, according to Intel’s (INTC) McAfee.

The security division’s research arm, which unveiled its second-quarter  threats report on Wednesday, also registered an alarming increase in mobile  ransomware samples in the second quarter and said spam continued to accelerate,  with more than 5.5 trillion spam messages being sent representing roughly 70% of  total global email volume.

“The mobile cybercrime landscape is becoming more defined as cybergangs  determine which tactics are most effective and profitable,” said Vincent Weafer,  senior vice president of McAfee Labs. “As in other mature areas of cybercrime,  the profit motive of hacking bank accounts has eclipsed the technical challenges  of bypassing digital trust.”

Among the primary methods used by thieves through Android devices were  SMS-stealing banking malware, fraudulent dating and entertainment apps,  legitimate apps laced with malicious weaponry and malicious apps posing as  useful tools.

The banking scheme takes advantage of commercial banks’ two-factor  authentication, capturing the traditional usernames and passwords then  intercepting the SMS that contains a log-in code so that hackers gain direct  access to accounts.

Fraudulent dating and entertainment apps dupe users into signing up for  non-existent services. Hackers augment profits by selling user information and  other personal data stored on devices.

Outside of mobile threats, the second quarter recorded a 16% increase in  suspicious URLs, a 50% increase in digitally-signed malware samples and notable  events in the cyber-attack and espionage areas.

The report comes amid ongoing attacks on the digital currency Bitcoin and  Operation Troy’s targeting of  U.S. and South Korean military assets,  McAfee said, as well as a resurgence of reported denial of service attacks  against major U.S. banks as well as an onslaught of attacks that have downed the  sites of several mainstream media outlets, including Washington Post and  CNN.

The increased pace of infiltration is a reflection of hackers adapting their  tactics to stay ahead of evolving security mechanisms and tweaking schemes to  drive the greatest profit.

Part of that includes using more ransomware, a type of extortion where  malware restricts access to the system it infects and demands ransom paid to the  creator. The number of new samples of ransomware exceeded 320,000 last quarter,  more than twice as many in the previous period.

It’s a “creative combination of disruption, distraction and destruction to  veil advanced targeted attacks,” McAfee said in the report.
