Wroba Trojan Resurfaces, Targets U.S. Users

SHARE
Banking Trojan

For the most part, Wroba Trojan activities were limited to the Asian countries. But very recently, researchers at Kaspersky Labs are seeing the mobile banking Trojan now targeting Android and iPhone users in the U.S with fake package-delivery notification. According to Kaspersky, during the Wroba Trojan campaign cybercriminals try to lure customers by sending them a text message. The message reads, “Your parcel has been sent out. Please check and accept it.”

Once an unsuspecting user clicks on the link, it goes either of the two ways depending on the OS on the mobile device.

If a user of an Android device clicks “OK,” they are redirected to a malicious site that reads, “Your browser is out-of-date and needs to be updated.” If the user clicks “OK,” the malicious application is downloaded onto the device. For iPhone users, the download doesn’t work. Instead, the iPhone users are greeted with a phishing page designed to look like Apple’s login page — in a bid to steal the credentials of the users.

Once the Trojan is installed on a device, it can perform several nefarious activities like sending fake SMSs, access financial transaction data, check installed packages, and steal contact list and credentials for financial data.  According to Kaspersky, Wroba belongs to a family of malware that attempts to steal mobile banking accounts as well as one-time passwords sent by banks for client authentication.
