AdaptiveMobile recommends mobile operators step-up security for their subscribers, as it witnesses a steady rise in virus attacks.

Recent analysis of data from AdaptiveMobile’s mobile operator customers suggests that two virus variants – CommWarrior and Beselo – are causing particular damage. While CommWarrior only affects Nokia Series 60 phones, Beselo attacks all smartphones, spreading via Bluetooth and MMS as a Symbian SIS installation file and is growing at four times the rate of CommWarrior.
