How Pop-Ups Could Brand You a Pervert or Crook.
Greetings. A New York Times article today explores the problem of Web-based “pop-up” ads being used to artificially inflate Web traffic.
I’d like to point out a potentially much more serious problem
related to pop-ups that can access arbitrary Web sites — they could be
used for purposes that could get innocent Web users into major legal
problems.
The issue of sites triggering unsolicited access to other sites is not new. In a message over a year ago (“Google’s new feature creates another user privacy problem”),
I discussed how Google’s triggering of top item “prefetch” in returned
search results could result in Firefox browsers visiting the referenced
site — and collecting any associated cookies — without users’
knowledge (I also suggested ways to prevent this behavior).
The essential problem is that Web logs that record users’ access to
sites would record such visits as if they had been voluntarily
initiated by those users. If those destinations happen to be sites with
various forms of “illicit” materials that could be the subject of
government or other investigations that would go digging through
associated access logs… well, you can imagine the possible
complications.
Google’s prefetch behavior is an example of a well-intended feature with unfortunate negative side-effects.
On the other hand, the sorts of nefarious pop-ups described in the
NYT piece have much greater potential for intentionally serious sorts
of damage, since they can be far more flexible and directed than simple
Web prefetches, and so could put innocent consumers at even greater
risk. They might not only access pages that could get people arrested
(perhaps c-porn?), but also download files that could trigger RIAA
and/or MPAA “automatic” lawsuits, or any number of other nightmare
scenarios.
It’s fair to ask why anyone might want to set loose such technical
monsters on innocent victims. The simple answer is that there are quite
a few people out there who just want to score a point — to prove that
they can do it — plus of course the sick minds who enjoy watching
other people suffer.
