The Heartbleed bug is still a very real issue for IT admins, but it’s far from the only issue. The latest woe comes in the form of a malicious Android application called iBanking. When you install it on your mobile
phone it can spy on your communications.
Security researchers at ESET, an antivirus vendor, identified the malware. Calling it a bot, the firm said it has phone-specific capabilities that range from capturing incoming and outgoing text messages to redirecting incoming voice calls to grabbing audio using the device’s microphone.
“As reported by independent researcher Kafeine, this mobile application was for sale in underground forums and was used by several banking Trojans in an attempt to bypass a mobile two-factor authentication method put forth by some financial institutions,” Jean-Ian Boutin, a malware researcher at ESET, wrote on the company’s blog.
From Banking to Facebook
Boutin explained that several banks around the world use this method, which is called “mobile transaction authorization number” or mToken in the financial realm, to authorize banking operations. However, it seems popular Internet giants like Facebook, Twitter and Google have also picked up the method.
“The way iBanking is installed on the user’s mobile is quite common, but it is the first time we have seen such a mobile application targeting Facebook users for account fraud,” Boutin said. “Although the Facebook two-factor authentication feature has been around for quite a while, it may be that there is a growing number of people using it, thus making account takeover through a regular account credentials grabber ineffective.”
Boutin said now that mainstream Web services such as Facebook are also targeted by mobile malware, it will be interesting to see whether other types of malware will start using webinjects, free tools for automated testing of Web services and Web apps.
“Will we see content injection functionalities and mobile malware used in non-financial types of malware so that they can take over accounts from popular Web services?” he asked. “Time will tell, but because of the commoditization of mobile malware and the associated code source leaks, this is a distinct possibility.”
PC Still Security Weak Link
We turned to Jeff Davis, vice president of engineering at Web information security solutions vendor Quarri Technologies, to get his take on the iBanking bot. He told us since Google has stepped up its game in filtering malicious apps from the Google Play store, Android malware authors have had to resort to novel and convoluted methods for getting their malware installed on users’ devices.
