Have I Been Pwned

I love cutting-edge tech, but I hate hyperbole, so I find AI to be a real paradox. Somewhere in that whole mess of overnight influencers, disinformation and ludicrous claims is some real "gold" - AI stuff that's genuinely useful and makes a meaningful difference. This blog post cuts straight to the good stuff, specifically how you can use AI with Have I Been Pwned to do some pretty cool things. I'll be showing examples based on OpenClaw running on the Mac Mini in the hero shot, but they're appli...

For a hobby project built in my spare time to provide a simple community service, Have I Been Pwned sure has, well, "escalated". Today, we support hundreds of thousands of website visitors each day, tens of millions of API queries, and hundreds of millions of password searches. We're processing billions of compromised records each year provided by breached companies, white hat researchers, hackers and law enforcement agencies. And it's used by every conceivable demographic: infosec pros, "mums a...

Remember the Ashley Madison data breach? That was now more than a decade ago, yet it arguably remains the single most noteworthy data breach of all time. There are many reasons for this accolade, but chief among them is that by virtue of the site being expressly designed to facilitate extramarital affairs, there was massive social stigma attached to it. As a result, we saw some pretty crazy stuff: 1. Various websites were stood up to publicly disclose the presence of people in the data and out...

The sheer scope of cybercrime can be hard to fathom, even when you live and breathe it every day. It's not just the volume of data, but also the extent to which it replicates across criminal actors seeking to abuse it for their own gain, and to our detriment. We were reminded of this recently when the FBI reached out and asked if they could send us 630 million more passwords. For the last four years, they've been sending over passwords found during the course of their investigations in the hope...

Normally, when someone sends feedback like this, I ignore it, but it happens often enough that it deserves an explainer, because the answer is really, really simple. So simple, in fact, that it should be evident to the likes of Bruce, who decided his misunderstanding deserved a 1-star Trustpilot review yesterday: Now, frankly, Trustpilot is a pretty questionable source of real-world, quality reviews anyway, but the same feedback has come through other channels enough times that let's just sort...

I hate hyperbolic news headlines about data breaches, but for the "2 Billion Email Addresses" headline to be hyperbolic, it'd need to be exaggerated or overstated - and it isn't. It's rounded up from the more precise number of 1,957,476,021 unique email addresses, but other than that, it's exactly what it sounds like. Oh - and 1.3 billion unique passwords, 625 million of which we'd never seen before either. It's the most extensive corpus of data we've ever processed, by a significant margin. Ed...

Where is your data on the internet? I mean, outside the places you've consciously provided it, where has it now flowed to and is being used and abused in ways you've never expected? The truth is that once the bad guys have your data, it often replicates over and over again via numerous channels and platforms. If you're able to aggregate enough of it en masse, you end up with huge volumes of "threat intelligence data", to use the industry buzzword. And that's precisely what Ben from Synthient has...

You see it all the time after a tragedy occurs somewhere, and people flock to offer their sympathies via the "thoughts and prayers" line. Sympathy is great, and we should all express that sentiment appropriately. The criticism, however, is that the line is often offered as a substitute for meaningful action. Responding to an incident with "thoughts and prayers" doesn't actually do anything, which brings us to court injunctions in the wake of a data breach. Let's start with HWL Ebsworth, an Aust...

It's hard to explain the significance of CERN. It's the birthplace of the World Wide Web and the home of the largest machine ever built, the Large Hadron Collider. The bit that's hard to explain is, well, I mean, look at it! Charlotte and I visited CERN in 2019, nestled in there between Switzerland and France, and descended into the mountainside where we saw the world's largest particle accelerator firsthand. I can't explain this! The physics are just mind-bending. A few months ago, we headed...

One of the most common use cases for HIBP's API is querying by email address, and we support hundreds of millions of searches against this endpoint every month. Loads of organisations use this service to understand the exposure of their customers and provide them with better protection against account takeover attacks. Many also use it to support customers who've already fallen victim - "hey, did you know HIBP says you're in 7 data breaches, any chance you've been reusing passwords?" Some compan...
