Details:
     There's a security issue in the implementation of virtual-keyboard.

As we all know virtual-keyboards should prevent from "keyloggers". In GlobeTrotter Mobility Manager [GTMM] implementation of virtual-keyboard when we "click" on some figure [for example when we are typing our PIN code] we can see effect of "active button", so good keylogger which can makes screenshoots will "sniff" that codes even when there's a virtual-keyboard.

Good virtual-keyboard shouldnt change view/size/depth/color/etc of button when someones is "clicking" on it [it should have "stoned-face"]. That issue/problem was mentioned many times, for example on SecurityFocus [publication, arts].

When I was making tests, my own short-coded keylogger easily "catched" [via screenshoots] all PIN codes that I was typing throught "bad" implementation of virtual-keyboard [in GlobeTrotter implementation of virtual-keyboard when we "click" on button it changes its color + we can see depth-effect]. As soon as it's possible Option Wireless Technology should fix that issue in software. When we have a good implementation of virtual-keyboard, when we click on some button that button doesnt change color/size or other effects of "active button". So even if keylogger is making a good screenshoots we do know nothing about typing password (especially when user likes to "fly-only"  [even unintentionally] over many buttons, but click only 4 of them).


Developers should read this: http://www.securityfocus.com/infocus/1829 [section Preventing Keystroke Capture.]


BTW. I didnt published it earlier because I thought that vendor will quickly fix it, but when I saw on the Internet that many "bad programms" are already waiting for GTMM, I decided to inform all of You (especially GTMM users). Beware :-D
