Hackers Use Banner Ads on Major Sites to Hijack Your PC

The worst-case scenario used to be that online ads are pesky, memory-draining distractions. But a new batch of banner ads is much more sinister: They hijack personal computers and bully users until they agree to buy antivirus software. And the ads do their dirty work even if you don't click on them.The malware-spiked ads have been spotted on various legitimate websites, ranging from the British magazine The Economist to baseball's MLB.com to the Canada.com news portal. Hackers are using deceptive practices and tricky Flash programming to get their ads onto legitimate sites by way of DoubleClick's DART program. Web publishers use the DoubleClick-hosted platform to manage advertising inventory." CT: Link updated to original source instead of plagerizer.

What are these "ads" you're talking about ?

That's why Firefox+NoScript+AdBlock Plus+Flashblock were invented

Adding insult to disgust to injury...

PayPal has a "Virtual Debit Card" that you can use to access your PayPal account. Prior to downloading the software, you're asked to verify your system requirements. If everything checks out, you can then download and install the software.

Here's the rub - when you click on the "Download Now" button, it actually sends you to DoubleClick.net site. Then the DoubleClick.net site redirects you back to the PayPal site and starts downloading the application. If you have DoubleClick.net blocked in your hosts file, like I do, then you can't download the software.

Why?

It is so that DoubleClick.net can plant a first-party cookie, spy on your activities, direct advertisements to you... PayPal has just submitted ALL your information AND the fact that you use PayPal, AND the fact that you purchase stuff online, AND, AND, AND... Then DoubleClick.net can target you for highly targeted advertisements.

This is just unconscionable. PayPal deserves all the flame they're gonna get over this one.
