Great. Just great. Now there are ad networks using banners to install malware.
The article from Netcraft goes on to say that some phishing attacks are using banners to install keystroke loggers and other spyware. So now, just by using an insecure browser* to click on the link in a message claiming to be from your bank can make it possible for hackers to steal your passwords, credit card numbers, etc., even if you realize the site’s a scam and don’t fill in the form. Fun, fun, fun!
Time to look into those alternative browsers again…
* Yes, security holes have been found in Mozilla, Opera, etc. With the rise in popularity of Firefox, some attackers are starting to target Mozilla. But aside from looking at the sheer number of holes in IE compared to other browsers, just about everyone seems to have a better track record at fixing vulnerabilities than Microsoft does.
