I like to start long blog posts with a tl;dr, so here it is: We've ingested a corpus of 1.5TB worth of stealer logs known as "ALIEN TXTBASE" into Have I Been Pwned. They contain 23 billion rows with 493 million unique website and email address pairs, affecting 284M unique email addresses. We've also added 244M passwords we've never seen before to Pwned Passwords and updated the counts against another 199M that were already in there. Finally, we now have a way for domain owners to query their en...

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 absolutely swamped me. Plus, I spent from then until now in Sydney at various meetings and events which was great, but didn't do a lot for my productivity. Be that as it may, we're now less than 12 hours off launching this all so, in the interests of not having me stay up...

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. I'm holding off sharing anything until we're far enough down the road that we're confident in the direction we're heading, and then I want to invite the masses to contribute as we head towards a (re)launch. Whilst I didn't talk about i...

I think what's really scratching an itch for me with the home theatre thing is that it's this whole geeky world of stuff that I always knew was out there, but I'd just never really understood. For example, I mentioned waveforming in the video, and I'd never even heard of that let alone understood that there may be science where sound waves are smashed into each other in opposing directions in order to cancel each other out. And I'm sure I've got that completely wrong, but that's what's so fun ab...

It's IoT time! We're embarking on a very major home project (more detail of which is in the video), and some pretty big decisions need to be made about a very simple device: the light switch. I love having just about every light in our connected... when it works. The house has just the right light early each morning, it transitions into daytime mode right at the perfect time based on the amount of solar radiation in the sky, into evening time courtesy of the same device and then blacks out when...

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 trip we did in September and spend the time meeting up with some of the law enforcement agencies and various other organisations we've been working with over the years. As I say in the video, if you're in one of these locations and...

It's hard to find a good criminal these days. I mean a really trustworthy one you can be confident won't lead you up the garden path with false promises of data breaches. Like this guy yesterday: For my international friends, JB Hi-Fi is a massive electronics retailer down under and they have my data! I mean by design because I've bought a bunch of stuff from them, so I was curious not just about my own data but because a breach of 12 million plus people would be massive in a country of not muc...

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 information" messages like I normally do when I load stealer logs! Instead, the feedback was resoundingly positive. This week I'm talking more about the logic behind this, some of the challenges we faced with it and what we might see in the future. Stay tuned, because...

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 API. Nasty stuff, stealer logs. I've written about them and loaded them into Have I Been Pwned (HIBP) before but just as a recap, we're talking about the logs created by malware running on infected machines. You k...

This week I'm giving a little teaser as to what's coming with stealer logs in HIBP and in about 24 hours from the time of writing, you'll be able to see the whole thing in action. This has been a huge amount of work trawling through vast volumes of data and trying to make it usable by the masses, but I think what we're launchung tomorrow will be awesome. Along with a new feature around these stealer logs, we've also added a huge number of new passwords to Pwned Passwords not previously seen befo...
