Report each domain to the major browser vendors so they can update their list of suspicious sites?
I believe the default configuration for suspected spam and phishing and other malicious sites is that the user gets a red warning page that they have to click through first. Website owner would either get notifications from users or notice the drop off in traffic?
Yeah, this is probably the right answer. Immediately protects users, and website owners would quickly find out as well. :-)
Primary obligation is to the users, not the owners of websites that got themselves infected.
This is it. Its hopeless now. I had a horrible realization a couple weeks ago with a small (single) person business. I showed them that their website was completely owned, crypto-miners ,malware, gambling pop-ups the works.
When I showed and asked who maintains her site, she said it regard to the malware, "All sites look like this"
That was when it hit me. They have won. The web is so full of garbage to the average person that they cannot even recognize it as it feeds on them.
The webadmin is some Chinese guy on upwork.
Why not try to warn the owners first? Taking the site off of those lists is a pain.
Bingo. Protect the users first. For example, you can report the websites to Google Safebrowsing: https://safebrowsing.google.com/safebrowsing/report_phish/
Quote from TFA:
> Supply chain - a third-party script file that a site loads is infected with malware, and is then loaded on to the site, exposing all visitors.
I already know many will disagree, but this is far too vague for your answer to make much sense. The list of 15k websites isn't given.
Most websites have at least one analytics script. Some of the biggest vendor names in that space have known XSS issues via nonce reuse that they aren't going to fix because it threatens their entire business model.
You usually get the whole clown car as soon as you allow one 3rd-party script for relatively innocent use cases like wanting a heatmap of user interaction.
You should fully expect that such a blacklist would take out most, if not all, of the websites you use every day. The security model for 3rd party scripts tends to be "trust me bro, we're $bigname"
I run a website where people can upload files. Not everyone uploads nice files. Every time someone downloads such a file from my site with their antivirus enabled, it's now my problem to discover which fifteen block lists the whole domain has newly been put on. People don't treat big tech this way; you don't think "oh, there's malware on Github, let me just report github.com as a suspicious website that nobody should be able to visit anymore"
The correct answer is probably the abuse contact shown in the WHOIS data. That's programmatically accessible and thus scales
