How to Protect Against Phishy Top-level Domains, Part 2

In a previous article, we explained that risk-averse organizations routinely adopt TLD blocking as a defense against cyber-attacks.

We EMPHASIZED why this is a last resort measure and offered examples of TLDs that were persistently associated with major phishing and scam attacks in CY2025. We also describe how to make an informed TLD blocking decision.

In our earlier post, we explained how organizations or individuals could use Cisco’s OpenDNS service to adopt TLD blocking. Today, we’ll be taking a look at how NextDNS could be used to block TLDs.

We really love that the Block CloudFlare MITM Attack (#BCMA) Add-on for #Firefox (and #TorBrowser) is finally offered by Mozilla.

Its not perfect, but it is version 1.0.0. 😃

We are concerned that the "Block request immediately" option could be used to fingerprint a person as a BCMA user. We are supportive of #blocklisting for min 6 months (currently it only stores the last 500 #MITM'd domains, but sites could get dropped from the list in a matter of weeks, given the preponderance of CF sites).
