Tracking down bugs in software is a pain that all of us who write code must bear. When we're talking about outright errors in a web page, you typically have something to get you started (such as output in the console), but that wasn't the case here: Sure! Reboots don't help :) Here are the two error screens which show up. pic.twitter.com/w2dmZcVyHk — Peter Vogel (@PeterVogel) July 11, 2025 That's on a Chromebook, and it's the first user report we had about the issue back in early July. Th...

It was the Synthient threat data that ate most of my time this week, and it continues to do so now, the weekend after recording this video. Data like this is equal parts enormously damaging to victims and frustratingly noisy to process. I have to be confident enough that it's new enough, legit enough and impactful enough to justify loading and that the value presented to breach victims sufficiently offsets the inevitable chorus of "what am I meant to do with this, tell me exactly what password w...

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're not going to believe this - the criminals that took the Qantas data ignored the injunction 😮 I know, I know, we're all a bit stunned that making crime illegal hasn't appeared to stop it, but here we are. Just before the time of writing, I was contacted by someone who received a breach alert from a similar service to HIBP in another part of the world and while it didn't explicitly say "Qantas" (side note: I hate it when other services redact the name), it sure as hell sounded like them ba...

This week's video was recorded on Friday morning Aussie time, and as promised, hackers dumped data the following day. Listening back to parts of the video as I write this on a Sunday morning, pretty much what was predicted happened: data was dumped, it included Qantas, and the injunction did nothing to stop it. I knew that in advance, and I'm also certain Qantas did too, but that hasn't stopped their messaging from implying the contrary: This wording remains worrying: "we have an ongoing inju...

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...

This probably comes through pretty strongly in this week's video, but I love the vibe at CERN. It's a place so focused on the common good of science that all the other cultural attributes that often put people at odds these days fade into the distance. That hit me more than it did on my last visit in 2019, perhaps because of the world events of late that have become so divisive. So, I'm exceptionally happy to give CERN the same level of access to HIBP data as we have the dozens of other national...

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...

I'm so happy to finally be getting those HIBP demos out! The first couple are simple, but as I say in this week's vid, it's the simple questions we're still dealing with. As if to taunt me (or prove my point), we got this ticket just a couple of hours ago: I’m looking at 10-12k api calls per year. Do you have a custom package that will fit this range? Now, let's see what happens if you drop that exact text into the chatbot on support.haveibeenpwned.com: There's literally a dedicated KB articl...

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...
