@JosKleverWebSupport DNS4EU automatically blocks malicious domains discovered by National CERTs, MISP, and OSINT. It employs machine learning and heuristics to detect threats, validating them against whitelists before propagating the block to its resolvers.

If the domain remains blocked, maybe it has been compromised and they cannot accept your request: remove it from your bookmarks and find a different website (or the same website on a different domain).😉

@JosKleverWebSupport you can't possibly know, most web attacks are unnoticeable. While I strongly advice to trust the secure DNS, you can add a DNS exception in your web browser for the specific domains you belive to be false positives.

you have full control: if the problem persists and you are 100% sure that the impacted domain is not malicious or compromised, the settings of Mozilla Firefox (and of other modern web browsers) feature a DNS exception list. Add the domain there and restart the browser.

I can know, because I know the admins of one site and I'm the admin of the other site.

Maintaining websites is my job, including updating and protecting websites and if necessary cleaning up hacked websites. So I know these sites are clean and have been so at least for the last couple of years.

@JosKleverWebSupport depending on your domain's past, two years may not be enough to get out of a permanent DNS blocklist.😅

Send me the domains in private, using the Visibility setting "Private mention", I'll check their status and eventually file a request for you.

Thanks, but if 1 report doesn't help, 2 reports won't help either.

I'm not using it at the moment, so I can't check the current status.

The issue is not these false positives, but the fact that they just don't respond to any channel. Than just don't publish a contact form or email addresses on your site.

@JosKleverWebSupport ok, I've checked the domain and it has been blocked because "the provider didn't act fast enough on SPAM abusers" and because "malware was detected on one of its pages". In fact, DNS4EU blocked it for "malicious content", meaning malware infection.

I've updated some of the online antivirus records.
If the previous conditions no longer subsist, the domains will be unblocked in the following days.👋

@JosKleverWebSupport no 🤣 I've simply checked a few public blocklists and antivirus sites, redo the scans to clear the old public caches results, so the domain no longer appears as compromised for now, and sent new removal requests. DNS4EU (and the other filtering DNSs) source a lot of other websites for their blocklists, which can lead to false positives. It won't be immediate, but if no longer distributes malware, the domain will be unblocked.

Let me know if you need more help.👋

In that case it would be better to let me know on which site(s) you've found an issue, so I or even better the responsible admins could request the removal. Because now we still don't know if there was an issue and how we could solve it.

And again, if DNS4EU based their blocking on another list, they can simply report it back to me on my attempts to reach them.

@JosKleverWebSupport you are simply a user and I couldn't verify you as a security contact or a staffer with adequate security clearance for that website/domain.

It will be unblocked when the threat is over for a while, if legally viable.🙂 👋

What? You know I'm not the admin for that site, but you do make changes based on my signal and you refuse to share publicly available data because of the same reason? That's very weird.

Please make clear what role you have in this, if you are involved with DNS4EU (not as a user) and what you have done using publicly available tools.

@JosKleverWebSupport I'm not special in any ways and I've already told you everything I can (see prev. message). Now, enjoy the good news.🙂

This afternoon a technician at Whalebone has completed the last checks. The domain is no longer blocked in DNS4EU (and soon removed from the global blocklists of the EU, after enough time for propagation).

Please set DNS4EU Protective as your DoH DNS, clear the browser cache, restart your computer and visit that domain you love, it will appear normally.

You didn't tell me everything, because you are keeping the facts to yourself.

Did you remove a blocklisting? Where?

Why mention a BS reason about security clearance? For what?

Why report a false positive you can't verify, but refuse to anything?

DNS4EU apparently replies to requests again, but they didn't for months, so it will take time to restore trust.

And please don't patronize me, by giving beginner instructions. That's insulting.

My requests were normal and friendly. They just don't communicate at all.

Maybe I give it another try later, but for now I'm looking for an alternative that doesn't ignore it's users completely.

"Do not edit your hosts file (it can be difficult to debug if the IP changes), use the exception list of your web browser instead, as it does not depend on a specific IP address."

Don't edit either of those! The Hosts file should only be used to fix bugs on your own LAN.

Add blocked sites to the router.

Absolutely never block by IP, only name.
