Public API changes

During March 2022 we received a significant spike in bot-based abuse of our public APIs, forcing us to implement some pretty harsh rate limiting while we got a handle on the situation. This rate limiting also impacted some of our legitimate users, especially through the last two weeks of March.

The silver lining is this abuse pushed us take greater advantage of CloudFlare's "edge" computation and DoS protection, and in migrating the majority of our public API endpoints to CloudFlare we were able to make a number of significant performance and quality updates too.

The "fuzz" and "parked" routes received the greatest improvement, the former with a 100-fold performance increase and the latter benefiting from improvements to our parked-website detection algorithm.

This might result in some requests returning slightly different responses than before, but those responses are now more accurate which we're sure you'll appreciate!

Welcome to 2022!

From all of us at dnstwister we hope you've had a pleasant Christmas and New Year, and we wish you all a safe year ahead.

Through the end of 2021 we released a number of small updates and bugfixes including extending our public API's "fuzzing" endpoint to include common phishing TLDs (a feature already available on our paid subscription plans) and publishing a transparent security page.

In 2022 we're planning to push out a lot more tools to support our subscribers with alert-response and we're continuing to broaden the tooling on this site too. As always please don't hesitate to let us know if there's something we can do to help you with your dnstwister use-case.

Feature Announcements

Since the last update we've been working hard on two updates to STIX2 indicators and a light UI refresh.

STIX2 indicators

We have just launched our first Threat Intelligence integration - STIX2.1 indicators for all search results.

For each result you can view or download (via permalink) a STIX2.1 indicator for the domain in question, the domain's IPv4 Address or URLs starting with that domain.

We're hoping to add further indicators in the future as you let us know what would help you. Right now STIX2 indicators can be accessed off any dnstwister search result and will be coming to paid-tier subscriptions and APIs soon!

These is an exciting new feature so if you've got any feedback - and as always - please don't hesitate to let us know.

UI updates

Since the last update we've also rolled out a refreshed UI with improved search progress and a number of other layout and mobile consistency improvements, hopefully you're also finding easier on the eyes and easier to use.

Feature Announcement: Alerts History

We're excited to announce that that all paid-tier subscribers now receive 30-day retention of their dnstwister alerts.

Every alerted-for domain in your emails now links back to its last 30 days of DNS A and MX record resolution history.

We're hoping this will be especially useful for subscribers who have hidden all alerts except those for new registrations when they experience a domain known to be registered becoming temporarily unresolvable and then re-alerting as "new" when it is next resolved without the critical context of why they are seeing it again.

This is an exciting new feature so if you've got any feedback please don't hesitate to let us know.
