The Exhibit A why no one will ever convince me to turn off my ad blocker or switch away from Firefox. It's a great feeling to just not have to worry about this entire class of exploits.

Or use a computer without a mic/webcam permanently embedded or attached. I'm glad I'm constantly reminded that not having such peripherals can be a good thing.

Still leaves the fingerprinting vector.

In my experience, with tools like Cover Your Tracks (apparently this is the new name for Panopticlick), the more you try and thwart fingerprinting, the more unique you appear. Although I still do everything I can to block and filter everything conceivable, I've given up on trying to figure out how identifiable I am on the web because it seems useless. If you don't try then you're identifiable, and if you do then you…

Fingerprinting with any accuracy is hard. As a legitimate use case, I had a corporate client who wanted their management software only accessible to sub-management employees from certain on-site locations. And they wanted this without sending those employees through a VPN or having a static IP for each location. So what I allowed them to do was to let a manager clear a given device's browser fingerprint (e.g. on the…

But isn’t this exactly what client-side certificates are invented for?

I think this sounds more like some sort of fingerprinting attempt. It good to see that random access to these kind of resources fails due to new(er) browser controls. However, this does not mean that the fingerprinting actually failed. There is probably some way to determine if the request was denied automatically by the browser or manually by the user (e.g., time to get "response"), which is definitely something whi…

That phenomenon is called the Streissand effect

This is not google, but a third party ad network serving ads through google. Google tries to sandbox the creatives in an attempt to prevent issues exactly like this, and develops browser features to prevent issues exactly like this. This is likely a script that somehow avoided google's malware scanning pipelines. This is definitely not google's malintent. Disclaimer: Ex googler, worked in ads, dealed with problems li…

IMO, if you serve content to the user, you're responsible for making sure you're not serving malware, e.g. by not allowing parties you cannot trust to serve arbitrary code. And this doesn't apply just to the ad network, it also applies to the publisher. I'd really like the publishers to be held liable for malvertising they serve. There is nothing inherently hard about serving safe ads, we've gotten pretty good at sep…

The browser is the main defense here. Google serves ads through iFrames. Browsers control resource access.

> I doubt you actually work there given your last sentence, What is your logic? My company uses Meet and it's "mandated" in the sense that it is used for all company meetings. I'm in a position that I might get us to switch if I pushed it, but Teams and Zoom aren't much better. I assure you I work at my company.

I meant not working for Google. I'm not sure about Teams, but Zoom lets you use a standard SIP client to join meetings.

Why do you think they claimed to work for Google? I didn't get that at all.

My company is now giving us those to use in our company laptops: https://m.media-amazon.com/images/I/61l+gnZORVL._AC_SY355_.j... They're pretty convenient and look nice

Our HP laptops have that built in

newer thinkpads do as well

Have you never built a computer before?

"In my experience, with tools like Cover Your Tracks (apparently this is the new name for Panopticlick), the more you try and thwart fingerprinting, the more unique you appear." In the interest of fair balance, I have had the opposite experience. "I've given up..." That's probably what "tech" companies are hoping you will do. I see this response repeatedly on HN when the fingerprinting topic comes up. I am wondering…

You don't have "googlesyndication.com" blocked?

Does anyone have first-hand experience with a company using fingerprinting in practice for the more standard marketing uses?

How does it work? What value does it provide? Who are the major players?

I work in marketing but feel like it’s a completely other world.

Hey, if you want, you can give me $200k/month and I'll scan your ads to make sure they're just flat fucking image files without any arbitrary bullshit code

It took 10 seconds of searching to find a flat fucking image file exploit. I even skipped the recent NSO group zero-click exploit. Enjoy - https://www.bleepingcomputer.com/news/security/new-stegano-e...

Doesn't seem like a great example since the image itself is perfectly safe. The exploit still needs JavaScript to extract and execute the payload embedded in the image, and then relied on Flash to install malware. Without JavaScript it's just an image like any other.

The NSO group iMessage exploit is a more interesting example, essentially turning a poorly bounded JBIG2 decompressor into a virtual machine.
