Cyber criminals are starting to move away from Windows and targeting other technologies, says a security report.
The annual report from net giant Cisco suggests that mobile phone operating systems are becoming increasingly popular with hi-tech criminals.
It predicts 2011 will see a significant number of attacks directed at smartphones, mobile software and users.
The trend towards mobile malware took a significant turn in late 2009, says Cisco with the appearance of a virus called Zitmo. This was a mobile version of the Zeus Windows trojan that has proved hugely popular with criminals keen to steal logins to online bank accounts.
