That recent Flash attack (smart.dll aka cn91x) reminded me of many things, it carried a very potent payload in its ability to bypass security, no doubt the best I'd seen for FFXI. When SE announced that our accounts were in jeopardy, the way they wrote it hinted that this was not just a keylogger. And in fact this payload could read running process memory and extract both POL login and passwords for your current account... it was written for WoW as well, written from the ground up so that antivirus and malware scans also failed to pick up its signature. People first detected it only through process/browser scanners and careful monitoring of NoScript, I imagine some poor souls could have even whitelisted the misspelled version of playonline.com...
A week later it all seems different. My normal antivirus picks it up right away, the current version of Flash (which was available over 2 months ago, hope you upgraded) is no longer susceptible to the buffer overflow error, and everyone by now has seen SE's warnings. Doesn't mean we're safe at all. If you got hacked, hope you changed some fundamental protocols and from now on devote time to keep abreast of security developments and keeping your machines updated.
