Trusteer recently uncovered two online banking fraud schemes designed to defeat one time password (OTP) authorization systems used by many banks. Unlike a previous attack Trusteer discussed that involved changing the victim's mobile number to redirect OTPs to the fraudster's phone, in these new scams the criminals are stealing the actual mobile device SIM (subscriber identity module) card.
In the first attack, the Gozi Trojan is used to steal IMEI (international mobile equipment identity) numbers from account holders when they login to their online banking application. The bank is using a OTP system to authorize large transactions.
