This is not really aimed at Adobe in particular, because it's happened to other companies too, but I think that the breach that got Adobe is going to have some long term affects on their products and customers...
My biggest concern is the security now with Adobe Acrobat Reader. Granted I stopped using this program a long while back (in favor of FoxIt's PDF Reader) but I do still have to use Adobe Creative Suite at work, and am concerned about rogue updates coming through, especially those for Acrobat. It just concerns me because if the source code is still floating around out there, wouldn't it be much easier for someone to write a "Fake" bogus update for Adobe that is in fact malware? Sure, AV apps should be able to catch them, but if they are using things such as Digital Signatures from Adobe (that could possibly have been stolen as well), wouldn't this put all Adobe users at risk?
I'm just concerns. I like their products (except Acrobat reader because it's such a resource hog), espeically Photoshop and Dreamweaver, but now whenever an update notice comes through for any Adobe product, I'm a bit wary. I mean, I'm always careful about updates, and usually will not use automatic updates to actually install updates, but only to alert me that there are updates, and then I go to the developer's site and download and install the update myself, but the problem with Adobe is that this is realy the only way you can get updates (is through an auto-update service) for most of its products.
