Perhaps it's just the time of year where we all start to wind down a bit, or maybe I'm just tired after another massive 12 months, but this week's vid is way late. Ok, going away to the place that had just been breached (ironic!) didn't help, but I think in general the pace we've maintained this year just needs to come back a bit. That said, I'll try to get this week's and next week's out on time, then it's off on travels for the next four weeks after that. Stay tuned for more IoT problems in a...

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...

Twelve years (and one day) since launching Have I Been Pwned, it's now a service that Charlotte and I live and breathe every day. From the first thing every morning to the last thing each day, from holidays to birthdays, in sickness and in heal... wait a minute - did we marry each other or a data breach service?! We decided to do a 12th-birthday special together today to give everyone a bit more insight into what she does and what life is like running this service. It's a different weekly vid, a...

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...

Well, I now have the answer to how Snapchat does age verification for under-16s: they give an underage kid the ability to change their date of birth, then do a facial scan to verify. The facial scan (a third party tells me...) allows someone well under 16 to pass it easily. So, is that control "reasonable"? I guess that will depend on whether this case is an outlier or a much more common scenario, and a sample set of one isn't particularly scientific. Either way, I expect that what we're seeing...

I gave up on the IoT water meter reader. Being technical and thinking you can solve everything with technology is both a blessing and a curse; dogged persistence has given me the life I have today, but it has also burned serious amounts of time because I never want to let a problem go unsolved. But sometimes, common sense and the ROI of my time have to prevail, so I packed up all the gear and went back to processing data breaches. If you happen to solve this problem in a way that doesn't require...

This week, it was an absolute privilege to be at Europol in The Hague, speaking about cyber offenders and at the InterCOP conference and spending time with some of the folks involved in the Operation Endgame actions. The latter in particular gave me a new sense of just how much coordination is involved in this sort of operation, all the way down to some of the messaging in the videos they've since released. I've seen some social commentary on these already, check them out and see what you think,...

What. A. Week. It wasn't just the preceding weeks of technical pain as we tried to work out how to get this data loaded, it was all the subsequent queries we had to deal with too. Some of them are totally understandable, whilst others just resulted in endless facepalms 🤦‍♂️ But we got there in the end with the worst of it just being a 24-hour period where we ended up on a SpamCop block list, for reasons I still don't understand. We are still on the very tail end of sending individual notificati...

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...

The 2 billion email address stealer log breach I talk about this week is almost ready to go at the time of writing. It's been massively time-consuming, massively expensive (we turned the cloud up to 11) and enormously frustrating. I've written about why in the draft blog post, but once you get to the point of inserting billions of records into a system with lots of billions of records, most of the usual way we'd do things totally goes out the window. I think we're looking at Wednesday morning Eu...
