Have I Been Pwned

As we gradually roll out HIBP’s Partner Program, we’re aiming to deliver targeted solutions that bridge the gap between being at risk and being protected. HIBP is the perfect place to bring these solutions to the forefront, as it's often the point at which individuals and organisations first learn of their exposure in data breaches. The challenge for corporates, in particular, is especially significant as they're tasked with protecting entire workforces, often against highly motivated and sophis...

I always used to joke that when people used Have I Been Pwned (HIBP), we effectively said "Oh no - you've been pwned! Uh, good luck!" and left it at that. That was fine when it was a pet project used by people who live in a similar world to me, but it didn't do a lot for the everyday folks just learning about the scary world of data breaches. Partnering with 1Password in 2018 helped, but the impact of data breaches goes well beyond the exposure of passwords, so a couple of months ago, I wrote ab...

This has been a very long time coming, but finally, after a marathon effort, the brand new Have I Been Pwned website is now live! Feb last year is when I made the first commit to the public repo for the rebranded service, and we soft-launched the new brand in March of this year. Over the course of this time, we've completely rebuilt the website, changed the functionality of pretty much every web page, added a heap of new features, and today, we're even launching a merch store 😎 Let me talk...

For many years, people would come to Have I Been Pwned (HIBP), run a search on their email address, get the big red "Oh no - pwned!" response and then... I'm not sure. We really didn't have much guidance until we partnered with 1Password and started giving specific advice about how to secure your digital life. So, that's passwords sorted, but the impact of data breaches goes well beyond passwords alone... There are many different ways people are impacted by breaches, for example, identity fraud...

I love a good road trip. Always have, but particularly during COVID when international options were somewhat limited, one road trip ended up, well, "extensive". I also love the recent trips Charlotte and I have taken to spend time with many of the great agencies we've worked with over the years, including the FBI, CISA, CCCS, RCMP, NCA, NCSC UK and NCSC Ireland. So, that's what we're going to do next month across some very cool locations in Europe: Whilst the route isn't set in stone, we'll...

Today, we're happy to welcome the Gambia National CSIRT to Have I Been Pwned as the 38th government to be onboarded with full and free access to their government domains. We've been offering this service for seven years now, and it enables national CSIRTs to gain greater visibility into the impact of data breaches on their respective nations. Our goal at HIBP remains very straightforward: to do good things with data breaches after bad things happen. We hope this initiative helps support the Gam...

How do seemingly little things manage to consume so much time?! We had a suggestion this week that instead of being able to login to the new HIBP website, you should instead be able to log in. This initially confused me because I've been used to logging on to things for decades: So, I went and signed in (yep, different again) to X and asked the masses what the correct term was: When accessing your @haveibeenpwned dashboard, which of the following should you do? Preview screen for reference:...

Designing the first logo for Have I Been Pwned was easy: I took a SQL injection pattern, wrote "have i been pwned?" after it and then, just to give it a touch of class, put a rectangle with rounded corners around it: Job done! I mean really, what more did I need for a pet project with a stupid name that would likely only add to the litany of failed nerdy ideas I'd had before that? And then, to compress 11 and a bit years into a single sentence: it immediately became unexpectedly popular, I adde...

I think I've finally caught my breath after dealing with those 23 billion rows of stealer logs last week. That was a bit intense, as is usually the way after any large incident goes into HIBP. But the confusing nature of stealer logs coupled with an overtly long blog post explaining them and the conflation of which services needed a subscription versus which were easily accessible by anyone made for a very intense last 6 days. And there were the issues around source data integrity on top of ever...

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...
