When using a shared computer at work, the morning after a colleague had stayed late after hours to “catch up on some work”, we discovered the Internet Explorerer Favourites crammed full with fairly unnerving hard-core porn sites.
(2) Porn sites now manage to use some nasty javascript-type-thing that automatically bookmarks them when you visit. (Like the endless series of pop-ups when you try to close a porn site window).
If you look in the folder called “cookies” there should be dozens of them for the sites he’s been to. Also, there might be some “history” left of the visits.
Usually they trick you into running their applet somehow. Just like email viruses try and trick you into opening attachments.
You can bookmark the page through javascript, but IE will pop up a confirmation box asking you to verify. The problem is that the person writing the javascript can put a message in that says “Click ‘Yes’ to enter the site”. So you get a popup box that says:
And apparently that fools people into clicking yes. They also do this to try and trick you into setting your homepage.
They even do the same thing with java applets that install things on your system (ALL BAD). People that don’t know better click yes when asked for authorization to access their local machine.
