A detailed analysis of the most malign in a recent spate of iPhone worms points to future mobile botnet risks.
The IKee-B (Duh) iPhone worm, released in late November, exploited default root passwords on jailbroken iPhones to turn the smartphones into botnet clients under the control of a server based in Lithuania. The worm affected iPhone users in The Netherlands, and specifically targeted customers of Dutch online bank ING Direct.
The iKee bot is one of the latest offerings in smartphone malware, in this case targeting jailbroken iPhones. While its implementation is simple in comparison to the latest generation of PC-based malware, its implications demonstrate the potential extension of crimeware to this valuable new frontier of handheld consumer devices.
