The computer crime authorities around the globe are becoming more experienced at tracking down hackers and virus writers, and given this latest arrest, malware authors should be asking themselves whether it's really worth taking the risk."
Earlier this year, a survey conducted by Sophos revealed that 81 percent of IT administrators said that they were concerned that malware and spyware were targeting mobile devices and will become a significant threat in the future.
However, nearly two-thirds (64 percent) admitted that they have no solution in place to secure company phones and PDAs.
