Been hanging around warez again ?

Well, if you downloaded and installed a pirated copy of Photoshop 6 or 7, get ready for a visit from the FBI. This article is self explanatory.

Homing Device Found In Photoshop 6 and 7
It was announced today by Adobe, Inc. that the upgrade to Photoshop 6.1 and Photoshop 7 added a special devices that 'phones home' the registration number and collected computer data to create a unique # (similar to what is found in Windows XP).

Obviously, this was a move to collect a list of its pirated software. Adobe has been compiling the list since the release of their free 6.1 upgrade last July. CNN reports that the list has been sent to the FBI, more here:

Adobe Systems, Inc, makers of the popular computer graphics program Photoshop, announced on Friday that they have compiled and submitted a list of more than 25,000 Internet Protocol (IP) addresses with duplicate serial numbers for versions six and seven of their product. A spokesman from Adobe says "We installed what is called a 'callback' on Photoshop to try and curb piracy. It essentially sends installation information to our servers upon first use." The FBI plans to work with national and local Internet Service Providers (ISP) to find and convict those responsible.

I know Flash MX and others are rumored to have these devices too. Pirates beware, it looks like the companies are coming after you.
Although it doesn't state it above, the adobe device only calls in once, during an idle period.
