Wait – it’s Tuesday already?! When you listen to this week’s (ok, last week’s) video, you’ll probably get the sense I was a bit overloaded. Yeah, so that didn’t stop, and the stealer log processing and new feature building just

We’re now eyeball-deep into the HIBP rebrand and UX work, totally overhauling the image of the service as we know it. That said, a guiding principle has been to ensure the new looks is immediately recognisable and over months of work, I think we’ve achieved that.

We’re heading back to London! And making a trip to Reykjavik. And Dublin. I talked about us considering this in the video yesterday, and just before publishing this post, we pulled the trigger and booked the tickets. The plan is to pretty much repeat the US and Canada

If I’m honest, I was in two minds about adding additional stealer logs to HIBP. Even with the new feature to include the domains an email address appears against in the logs, my concern was that I’d get a barrage of “that’s useless

TL;DR — Email addresses in stealer logs can now be queried in HIBP to discover which websites they’ve had credentials exposed against. Individuals can see this by verifying their address using the notification service and organisations monitoring domains can pull a list back via a new
