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.
So now I need to buy penis-enlargment pills AND and anti-virus.

I've never come across one of these ads. In fact, I rarely get ads as I use the Adblock Plus plugin for Firefox. This just gives even more reason to ban advertisements entirely. Thanks!

I use these exclusively, are there reports that this method gets by them? I know that if the ad is blocked, it isn't downloaded, but is that all it takes, download the ad and you have the virus?

Sounds like a reason to just block all double-click items...
I don't enable flash/scripts on any page unless it is needed -- like scripts for

Great, now we can await a round of finger pointing to begin over who is liable.

The "let's ban it" attitude seems awfully familiar. Are you a member of the US, UK, or EU parliament by any chance?
Like it or not, but advertising generates (directly and indirectly) the revenue that drives the Internet. When advertisement is passive, and does not attempt to hijack your computer, it is theoretically an win-for-all scenario: the advertisers get their clients, the consumers get their products, and the sites that host the advertisement get their costs and expenses covered.
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.
...and since those sites outsource to Doubleclick, they'll point a finger at them. Doubleclick will no doubt point the finger at some previously-unheard-of company that "solicits advertisements for the Doubleclick network", and they'll point the finger at their "client."
Meanwhile, The Economist, MLB, Canada.com, etc won't take responsibility for the content they present on their website (after all, they chose to use Doubleclick, they chose to put advertisements on the website, they chose not to require approval of ads before they were shown on their website, etc.) Funny how everyone is trigger-happy when it comes to copyright, but when it comes to content they present causing harm, it ain't theirs, eh? :-)
Doubleclick, of course, won't accept responsibility for vetting advertising distributed via their channel (which seems like a standard business procedure for, oh, an advertising network?) The only comfort is the mechanism of the free market: if website users get pissed enough, said websites might put pressure on Doubleclick or leave them altogether. That's bad for Doubleclick business, so maybe Doubleclick will consider vetting ads better, or run checks to see that flash code doesn't do certain things, etc. Then again, if the malicious banner ad suppliers are paying good enough money, Doubleclick may be perfectly happy to issue a press release "apologizing" and keep right on doing business as usual.

The flibby link is identical to this Wired blog post by Betsy Schiffman, dated four days earlier.
This is a good enough reason for ISP's concerned about security to block DoubleClick. You spam the net with bad referrals you get binned. Also think of the traffic that would get binned, way better than blocking p2p.
Do it for a month and DoubleClick and their ilk will be extra sure about not hosting bad stuff.
Right, we all use Adblock and the like. Yet, you can't force everyone in the vicinity to do so, there are lesser minds who opt for Opera, and there's even a tiny portion of giants on Links -- and let's not even mention how low SOME folks can fall.
I would say that adzapper (if you use squid) or a DNS-based blacklist is quite mandatory wherever you do have a say. Glancing at the logs of ISPs I have root at, roughly 1/4 of all freaking http requests go to lowlifes -- and even that based on my grossly incomplete list of ad/spyware/tracking scum.
Yeah, 25%. That's horrible.
And there are some customers dumb enough to complain if you do protect them from ads, so you can't do this in an ISP scenario. But in a company, school or family? Hell yeah, there's no reason for doubleclick.com to get through, ever.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
This has been going on since flash 8 was released with a vulnerability. I got hit by this about a year ago, maybe a little more.
Suddenly windows security center, that I routinely turn off because I can't stand the nagging, started up and told me that my computer was insecure and that I should go to a certain website and buy their virus defender software.
Not very subtle to a savvy person like myself, but I imagine some people would fall for it.
The box also started throwing up connection error message boxes, presumably because my external firewall were blocking outgoing connection attempts. Again not subtle, but it's an uncommon setup for a home user.
Third, it must have rooted the box somehow because certain files became invisible. "test.exe" among them. Renaming a textfile to text.exe would make it disappear, and the folder would be unremovable. Cygwin came to the rescue there. Also I noticed only because I happened to have lots of little crap programs laying around.
The virus scanners did not pick up on this.
This is the only time I have actually contracted a virus. Needless to say I hosed the box (PING is not disk image). What I learned from the experience is that knowing your system is way more effective than a virus scanner, and B) don't trust flash which is how I got the damn thing. I thought I was safe with firefox.
Content providers need to be responsible for the content of the ads posted on their sites - that's a given. TFA indicates that these content providers (the people behind NHL.com, for example) simply received payment for these ads via credit card or wire transfer and then posted the content. If these sites used a network television model, they would have intimate relationships with the advertisers and would work together to provide less offensive and more effective ads. I don't think they need to go that far (network television ads are far from perfect, although they are quite effective), but clearly MLB.com and NHL.com need to be held responsible for the content on their sites, and hopefully this will encourage better cooperation between site hosts and advertisers.
I'm pretty sure it does because I had to wait 30 seconds for any page of Slashdot's to render fully yesterday because Firefox was busy waiting for ad2.doubleclick.com or somesuch subdomain of theirs. The current page source certainly has doubleclicky ads.
Now, granted, the malware distributors typically tag ads for subjects not often seen on Slashdot (but I get them on, e.g., the Sinfest comic - huh, imagine that).
I'd say it's about time Doubleclick (that's you, Google, if you finally get to say you did indeed acquire it and everybody OK'd the deal.) gets held a little more responsible for this sort of thing being done through their network for which they collect money.

Everyone is cheering for AdBlock when they read this, but why is it ok that a browser can install spyware, viruses, etc when you are browsing a web page? Shouldn't this be something that can only happen on sites that you explicitly permit or upon agreeing to a dialog asking if it's ok to run a given program? If you can experience this problem with double-click, then you can experience the same problem with any web site out there, so I'd much rather see us fixing the security holes in various browsers.
WareZ engines like astalavista.com
It is 2007!
They now say: "Note: Astalavista.com is NOT affiliated with Astalavista.box.sk, there are NO cracks/serials/keygens/warez etc. hosted on the Astalavista.com's server, and never were! Moreover, Astalavista.com is a security site, therefore requests for anything illegal are simply directed to the wrong party, and get ignored immediately!"

From TFA: The malware looks like a ordinary Flash file, with its redirect function encrypted, so that when publishers upload it, the malware is not detectable.
.swf file. If you don't like that policy, then you can find another distributer for your ads. If your actionscript is so convoluted or obfuscated that doubleclicks programmer can't figure it out, then you can wait in line until the programmer can figure it out, or you can simplify it.
All Doubleclick has to do is require the actionscript source code for all ads. There is *no good reason* for an advertiser to hide anything from doubleclick. Send doubleclick your sourcecode. They will compile it into a
Problem solved.
When you find a company that allows people to use their copyrighted material however they want, and also takes responsibility (monetarily and apologetically both), for their own mistakes, let me know. And they have to still be in business, that is..
There's a related hole in Google Maps, an "open redirector", that allows this exploit. Here's an example:
Caution - hostile URL Close the page displayed; don't click on anything on it. .
Note that it fools Slashdot, and most link scanners in spam filters, into accepting the URL as leading to "google.com". But, in fact, it redirects to the "malware-scan.com" hostile site, which will try to install an Active-X control.
We've been finding attacks like this up with SiteTruth, by using PhishTank information to down-rate sites that have open redirectors. We've found open redirectors on Google and AOL. They're actively being exploited.
So we're currently down-rating Google, and AOL.. It may seem drastic to downrate an entire major site because they have a few "minor" exploits. PhishTank itself only blacklists specific hostile URLs. But that's no longer enough. Most modern phishing attacks use a unique URL, and often a unique subdomain, for each user attacked. SiteTruth thus takes a harder line. If a domain hosts something one of the data sources says is an attack, it downrates the whole domain automatically.
It's within the power of the site operator to close such security holes. We encourage them to do so.
And speaking of "trigger-happy", you seem to point the finger right back at the Web sites for not inspecting the ads and the underlaying code. Well, that's what they hire DoubleClick for,
And who decided to hire DoubleClick, instead of (as you mention) Google AdSense or a hundred other advertising networks, all of varying reputation, levels of annoying-ness, etc? Who negotiated the terms of the contract, which could have required vetting of ads by Doubleclick? Who had the power to chose between text, GIF, and Flash based ads? Who benefits financially from the presentation of those ads?
So, again tell me who is responsible for ME getting an infected PC visiting that website? If GM makes a car and the wheel falls off because Bob's Bolts sold them defective bolts, I can still sue GM for selling me a car on the reasonable assumption that GM would test bolts before putting them in a hundred thousand vehicles...and GM made the decision to buy from that particular supplier.
The way the world works is: I sue GM. GM then sues Bob's Bolts for damages (ie to reputation, the money they had to give me and spend on legal defense, cost of recall, etc.) Bob's Bolts then may sue Smith's Steel for selling them crappy steel.
Or, in this case: I sue The Economist for infecting my machine. The Economist turns around and sues Doubleclick for providing malicous ads. Doubleclick may then turn around and sue the company that made the malicious ads, for violating the terms of contract with Doubleclick specifying no malicious content...

...the monkey punches you.
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.
Good security is based upon reality and common sense. Common sense is a function of having common knowledge.
One should click the "X" to close out such windows - or likely better yet, especially when in doubt, do so via keyboard CTRL-F4 (think that's the combo).
... don't trust any option shown, use the "X" instead; that's not full-proof either, but much safer than clicking "No", "Cancel", etc.
Anyone who has done some VB programming, etc is well aware that the labels on dialogue boxes can say most anything and be assigned to most anything - problem here is that most Window's users don't know that "Cancel" can be assigned to the same function as "Yes", etc

I clicked on your "not a new problem" link. Avast (free edition) popped up a Trojan warning. What exactly is on that page?
Even in a web page, someone can make an image that looks exactly like a default message box on your OS (which can be guessed from the User Agent string) and have every part of that image tied to malicious results.
btw, yeah, Ctrl-F4 is close for a window (like a message box) and Alt-F4 is close for an application or new browser window.
