Researchers Defeat Perceptual Ad Blockers, Declare 'New Arms Race' (vice.com)
dmoberhaus writes: Perceptual ad blockers were supposed to be the "superweapon" that put an end to the arms race between advertisers and users. According to new research, however, perceptual ad blockers will come out on the losing side in the war against internet advertisers and expose users to a host of new attack vectors in the process. Researchers at Stanford tricked six different visual classifiers used in perceptual ad blockers with adversarial ads designed to trick the ad blockers by making nearly imperceptible changes to the ads. "The researchers tried several different adversarial attacks on the perceptual ad blockers' visual classifiers," Motherboard reports. "One attack, for example, slightly altered the AdChoices logo that is commonly used to disclose advertisements to fool the perceptual ad blocker. In another attack, the researchers demonstrated how website publishers could overlay a transparent mask over a website that would allow ads to evade perceptual ad blockers."
"The aim of our work is not to downplay the merits of ad-blocking, nor discredit the perceptual ad blocking philosophy, which is sound when instantiated with a robust visual ad detector," the researchers concluded. "Rather, our overarching goal is to highlight and raise awareness on the vulnerabilities that arise in building ad blockers with current computer vision systems."

If you want to get rid of ads, you shouldn't be looking to completely prevent them from loading because that's an eternal game of cat and mouse. Instead, you should be looking to poison advertisers click-though information. Basically, fooling ads into thinking you have clicked them and loading things in the background (after you have loaded the page excluding the ads) would have a very negative effect on advertisers because it spoils the very thing they keep track of: who clicks-through to a site. If most people provided a completely false click-through and browsing information it would diminish the value of ads entirely.
Honestly, people are fighting ad networks all wrong.
Anons need not reply. Questions end with a question mark.
That's how I do it. I use NoScript, and rarely ever see ads. The ads themselves are all being served up from some other site anyway, so even if I allow the scripts coming from the site itself, the ads are still blocked, which is fine by me.
If advertisers really want me to see ads, the simple solution is to stop being assholes. Stop using tricks like native advertising to deceive users, stop redirecting to God knows which questionable and potentially malicious sites, stop advertising scams, and in general stop being so hostile. They'll piss and moan about how I'm taking away advertising revenue, when really, all I want to do is keep myself and my machine safe. You guys are the ones who started the hostile behavior, not me, so don't be surprised when I react accordingly.
If they really want me to see ads, it is simple. Have an image, using standard basic Img tag, saying 'Drink Brand X Cola!' or whatever, clearly linking to brandXcola.com. There, simple. No scams, no malware, no tricks, transparent and honest. If they don't want to do that, then it's not my problem if someone's unethical behavior bites them in the ass.
>" don't know why ad blockers don't then just implement the obvious: Load the ad. Load the javascript. Just turn all the pixels that you display for those ads to white, and all the sound to zero volume. [...]What are the obvious flaws to this design that I am missing?"
1) Because that still causes the page to load very, very slowly. Try it- the speed difference is almost unbelievable on many sites. Many sites that load and render in 3 seconds suddenly take 6, 10 or even more seconds.
2) Because it doesn't help prevent tracking and spying.
3) Because it doesn't reduce bandwidth/date usage.
4) Because it doesn't reduce memory, CPU, and power/battery usage.
