Sophos issues advice about Brador Pocket PC backdoor Trojan horse

PDA users need not panic as no reports of Trojan in the wild

Researchers at Sophos have reported the discovery of a backdoor Trojan horse for the Pocket PC PDA platform.

Troj/Brador-A runs on the Pocket PC operating system, opening a backdoor which could allow hackers to take remote control of compromised PDAs. Brador is not a virus, and does not replicate itself via email. It can only work on PDAs running the Pocket PC operating system on an ARM processor.

"With no reports of this PDA Trojan in the wild it seems like this is more of a storm in a teacup rather than a threat which should give system administrators sleepless nights," said Graham Cluley, senior technology consultant for Sophos. "The real and present danger is the numerous virus attacks which are happening every day on desktop computers running good old fashioned Windows. That's where businesses should be focusing their attention right now when it comes to securing their systems."
