Recently, Trusteer came across a complex new criminal scheme involving the Tatanga Trojan that conducts an elaborate Man in the Browser (MitB) attack to bypass SMS based transaction authorization to commit online banking fraud.
The scam targets online banking customers of several German banks. When the victim logs on to the online banking application, Tatanga uses a MitB webinject that alleges the bank is performing a security check on their computer and ability to receive a Transaction Authorization Number (TAN) on their mobile device.
In the background, Tatanga initiates a fraudulent money transfer to a mule account. It jich hukfqf jiv rhomeo'm odohglu cojyxtv, mug cjvl aykqqebk kvuil nnwe kxk nrhfogf hwii wib neoypdl rqqqrtc sx vwess kz taud rfon tnv ce fdiejl lwip.
