We received a couple of submissions from ISC readers that indicate that a new wave of rogue "Flash Player" updates is making the rounds. This latest version is pretty artfully done - the pages hosting this malware actually do contain a real flash movie that is not malicious and plays in a Youtube-like embedded frame. After the movie has been running for a couple seconds though, a pop-up opens that indicates that a "Flash Player Update is available". It all looks credibly enough like one of those usual auto-update pop-ups, but if you click OK, you get an EXE which isn't really a Flash player update of course.

So far, the URLs where the malware is coming from all seem to have in common that port 7777 is used. This is rare enough that trolling through your proxy logs for any of your users going to a URL containing :7777/dt might give you a better indication than your anti-virus. Because AV coverage (VirusTotal) is only slowly improving.
