After the Android Market, it's now the turn of BlackBerry devices, Trend Micro is reporting that a Zeus trojan variant has begun infecting BlackBerry devices.
The ZeuS malware is currently detected by Trend Micro as BBOS_ZITMO.B. Just like its desktop counterpart, this ZeuS variant doesn't display any GUI that can prompt users about the infection. Instead, it removes itself from the list of apps, in order to effectively stay under the radar.
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.
Zeus variants have also been spotted on Symbian and Windows Mobile phones.
BBOS_ZITMO.B is capable of carrying out the following commands:
- Display SMS: Unmonitored SMS will be treated as a normal SMS and will be displayed on the phone.
- Delete/Drop SMS: SMS from hacker will not be seen by the user.
- Forward SMS: Send SMS to hacker without the user's knowledge.
- Block Calls
- Remove Block Calls
- Set Administrator: Register a new administrator.
- Add Sender
- Remove Sender
- Set Sender
- Block/Unblock Phone Numbers
