Two Popup Windows, On A Blog, Is Malware

If there is anything more obnoxious than the FaceBook "Like my blog!" popup window, it's a FaceBook "Like my blog!" window, preceded by a generic popup window.

It's possible that a blog which starts with two popup windows, one followed by a second, represents a blog owner who honestly wants people to enjoy her (his) blog. Even so, a blog that starts out this way is going to present a security analysis challenge, at best.

Seeing the growing popularity of the FaceBook popup (among blog owners, anyway), it's possible that the security scanning processes will, eventually, find a way to bypass the FaceBook code, and continue scanning. This may avoid some spurious malware classifications - if FaceBook developers can find a way to certify a genuine FaceBook popup.

Generic popup windows, on the other hand, need to be dealt with, sternly.

Every IT security consultant, with any experience, has seen the well known advice
Your computer may be infected with xxxxxxx malware. Download yyyyyyy remedy to remove xxxxxxx! OK to install?
That is a generic popup window. In this example, "xxxxxxx" is non existent - the install of "yyyyyyy" is merely the start to installing the "zzzzzzz" botnet member software.

Generic popup windows are suspicious.

Seeing a generic popup window, almost all security scanning processes are going to go into immediate threat detection status. Any blog, hosting a generic popup, should be immediately quarantined - so it can be scanned, through several levels of links, for a malware payload which surely hides somewhere.

A generic popup window, followed by a second popup, is even more suspicious.

Any blog which hosts a generic popup window, followed immediately by a FaceBook "Like my blog!" popup window, must be regarded with even more suspicion. It does not take any amount of paranoia (a mindset normal for all IT security professionals) to imagine a devious malware producer releasing his (her) own bogus FaceBook popup - with a little extra code added.

The generic popup window, preceding a bogus "FaceBook" popup, is then used as a "false flag" device, designed to confuse the security scanning software - so the malware delivered by the bogus FaceBook popup will be ignored.

The two popup windows, one after the other, may conceal malware installation.

Seeing the growing popularity of the FaceBook popup, surely there are malware vendors out there, planning just that technique, to deliver their product - if not already done.

Any blog owner, who adds both popups to her (his) blog needs to expect to receive a locked blog - followed by a locked Blogger account, as a devious / non repentant malware publisher.
