Android Trojans spread by Bluetooth, hijack bank codes

John P. Mello Jr. | June 12, 2013
Mobile malware gets more complex, defeats two-factor authentication.

Bugat has been tardy coming to the SMS code-snatching game, Kessem explained.

Bank Trojan writers began focusing their attention on mobile devices in 2012, as the use of SMS authentication codes began cutting into the effectiveness of their malware. "They saw that they needed to get into mobile because it's where their transactions were failing and their fraud rates falling," Kessem said in an interview.

"Bugat has been around for quite a while, so it's getting into the SMS game a little late," she added.

That's surprising since Bugat is a widespread banking Trojan, ranking behind the infamous Zeus banking Trojan in popularity among cyber bank robbers.

The addition of an SMS redirector could boost Bugat's popularity in the bank Trojan market, which is now divided among Zeus, Bugat and Citadel. "When Citadel began getting attention in the Western press, it began decreasing its availability," Baylor, of NSS, explained."So we may see an ascendance of Bugat."
