"It's just three weeks since the 29A virus group delivered Duts (http://www.viruslist.com/eng/viruslist.html?id=1874404), the first proof-of-concept virus for PDAs [Personal Digital Assistants] running PocketPC, and already we have a viable Trojan horse that targets these handheld devices. The new Trojan, called Brador (http://www.viruslist.com/eng/viruslist.html?id=1984055), was written by a Russian malicious code writer, with the accompanying text, "Get to work, folks, the PocketPC market will soon explode". The number of devices used within the corporate world is increasing. In particular, the use of handheld devices - PDAs and smartphones - is growing significantly and with it, the use of wireless technology of one sort or another (802.11b, Bluetooth, etc.). These devices are quite sophisticated. They run IP services, offer web access and are hooked up to corporate networks. They also give users the ability to connect remotely to other devices and networks. Unfortunately, they're intrinsically less secure, operating outside the reach of traditional network security safeguards. And as they start to carry more and more valuable corporate data, wireless devices and wireless networks become a more attractive target for the writers of malicious code. History has shown that in the development of applications, devices and networks ease of access is delivered ahead of security. Since these devices live outside traditional network security, they could easily become the weakest link in the corporate security system. The author of Brador is the first coder to actively engage the PDA virus market; he is offering to sell the client part for Brador to all interested parties. The virus writing industry has arrived indeed: virus coders are producing effective malware and selling it openly. "We were certain that a functional malicious program for PDAs would appear soon after the first proof of concept viruses emerged for mobile phones and Windows Mobile', commented Eugene Kaspersky, Head of Anti-Virus Research at Kaspersky Labs, 'WinCE.Brador.a is a full-scale malicious program ready to go: unlike proof of concept malware, Brador has a complete set of destructive functions typical for backdoors. Moreover, the offer to sell the client part proves that today, virus writing is big business"."
