AT&T's USB-based 3G broadband adapter uses an application called the "AT&T Connection Manager". I installed it today in order to use the USB adapter I borrowed from a friend. This evening I was surprised by the following spyware'y looking dialog.

This is a really scary update dialog. Nowhere in the form does it indicate what the updates are for, who they are coming from... nothing. Additionally, it doesn't show up in the taskbar. Anybody who would blindly click anywhere on that form is an idiot.
I popped up the task manager and the dialog showed under the "Applications" tab as ...

I right clicked it and tracked it down to its 'process', which is 'ATTCM.exe'...

Apparently either AT&T doesn't give a rip about computer security or they expect their broadband widget will only be used by power users. So, if you buy a USBConnect 881 device, you need to be a power user who knows how to validate an application window's identity, or you should just wildly click on vague applications and give them permission to continue; otherwise you may not get critical security updates!
