On 1 March 2016, the U.S. Attorney’s Office posted information that the leader of global cybercrime campaigns known as "Unlimited Operations," targeting global financial institutions (including an Omani bank), had pleaded guilty to "Computer Intrusion And Access Device Fraud Conspiracies". The defendant was identified as Ercan Findikoglu, a 34 year old Turkish citizen also known by the online nicknames “Segate,” “Predator,” and “Oreon.".
I encourage you to read the redacted indictment (posted here) for further information about modes of operation.
