Zeus malware variant begins targetting BlackBerry users
The trojan installs silently and then notifies its administrators that the compromised device is ready to receive instructions. Trend notes that an infected BlackBerry can be forced to block calls and phone numbers, add administrator accounts, turn the device on or off, and forward, delete, and display SMS messages.
While BlackBerry devices seem to be the primary target, Zeus variants have also been spotted on Symbian and Windows Mobile phones.
As is the case with desktop malware, vigilance and knowledge is the best defense: don't install untrusted apps and don't visit links you're unsure of on your mobile device.
