Banks. They screw us on interest rates, they screw us on fees and they screw us on passwords. Remember the old "bank grade security" adage? I took this saying to task almost a decade ago now but it seems that at least as far as password advice goes, | Continue reading
"More Data Breaches Than You Can Shake a Stick At". That seems like a reasonable summary and I suggest there are two main reasons for this observation. Firstly, there are simply loads of breaches happening and you know this already because, well, you read my stuff! Secondly, Ther … | Continue reading
Data breach verification: that seems like a good place to start given the discussion in this week's video about Accor. Watch the vid for the whole thing but in summary, data allegedly taken from Accor was published to a popular hacking forum and the headlines inevitably followed. … | Continue reading
I suggest, based on my experiences with data breaches over the years, that AT&T is about to have a very bad time of it. Class actions following data breaches have become all too common and I've written before about how much I despise them. The trouble | Continue reading
A serious but not sombre intro this week: I mentioned at the start of the vid that I had the classic visor hat on as I'd had a mole removed from my forehead during the week, along with another on the back of my hand. Here in Australia, | Continue reading
Let's get straight to the controversial bit: email address validation. A penny-drop moment during this week's video was that the native browser address validator rejects many otherwise RFC compliant forms. As an example, I asked ChatGTP about the validity of the pipe symbol durin … | Continue reading
I hate having to use that word - "alleged" - because it's so inconclusive and I know it will leave people with many unanswered questions. But sometimes, "alleged" is just where we need to begin and over the course of time, proper attribution is | Continue reading
I'm in Japan! Without tripod, without mic and having almost completely forgotten to do this vid, simply because I'm enjoying being on holidays too much 😊 It was literally just last night at dinner the penny dropped - "don't I normally do something | Continue reading
Over the last 6 years, we've been very happy to welcome dozens of national governments to have unhindered access to their domains in Have I Been Pwned, free from cost and manual verification barriers. Today, we're happy to welcome Liechtenstein's National Cyber Sec … | Continue reading
Let me begin by quoting Stefan during the livestream: "Turns out having tons of data integrity is expensive". Yeah, and working with tons of data in a fashion that's both fast and cost effective is bloody painful. I'm reminded of the old | Continue reading
Back in 2018, we started making Have I Been Pwned domain searches freely available to national government cybersecurity agencies responsible for protecting their nations' online infrastructure. Today, we're very happy to welcome Germany as the 35th country to use this s … | Continue reading
How on earth are we still here? You know, that place where breached companies stand up and go all Iraqi information minister on the incident as if somehow, flatly denying the blatantly obvious will make it all go away. It's the ease of debunking the "no breach | Continue reading
It's just been a joy to watch the material produced by the NCA and friends following the LockBit takedown this week. So much good stuff from the agencies themselves, not just content but high quality trolling too. Then there's the whole ecosystem of memes that have | Continue reading
I've been getting a lot of those "your parcel couldn't be delivered" phishing attacks lately and if you're a human with a phone, you probably have been too. Just as a brief reminder, they look like this:These get through all the | Continue reading
It's a short video this week after a few days in Sydney doing both NDC and the Azure user group. For the most part, I spoke about the same things as I did at NDC Security in Oslo last month... except that since then we've had | Continue reading
Somehow, an hour and a half went by in the blink of an eye this week. The Spoutible incident just has so many interesting aspects to it: loads of data that should never be returned publicly, awesome response time to the disclosure, lacklustre transparency in their disclosure, som … | Continue reading
Ever hear one of those stories where as it unravels, you lean in ever closer and mutter “No way! No way! NO WAY!” This one, as far as infosec stories go, had me leaning and muttering like never before. Here goes:Last week, someone reached it to me | Continue reading
I told ya so. Right from the beginning, it was pretty obvious what "MOAB" was probably going to be and sure enough, this tweet came true: Interesting find by @MayhemDayOne, wonder if it was from a shady breach search service (we’ve seen a bunch shut down | Continue reading
I've always thought of it a bit like baseball cards; a kid has a card of this one player that another kid is keen on, and that kid has a card the first one wants so they make a trade. They both have a bunch of cards they& | Continue reading
I spent longer than I expected talking about Trello this week, in part because I don't feel the narrative they presented properly acknowledges their responsibility for the incident and in part because I think the impact of scraping in general is misunderstood. I suspect many … | Continue reading
They're an odd thing, credential lists. Whether they're from a stealer as in this week's Naz.API incident, or just aggregated from multiple data breaches (which is also in Naz.API), I inevitably get some backlash after loading them: "this doesn't | Continue reading
It feels like not a week goes by without someone sending me yet another credential stuffing list. It's usually something to the effect of "hey, have you seen the Spotify breach", to which I politely reply with a link to my old No, Spotify Wasn' | Continue reading
Geez it's nice to be back in Oslo! This city has such a special place in my heart for so many reasons, not least of which by virtue of being Charlotte's home town we have so many friends and family here. Add in NDC Security this | Continue reading
It's another weekly update from the other side of the world with Scott and I in Rome as we continue a bit of downtime before hitting NDC Security in Oslo next week. This week, Scott's sharing details of how he and Joe Tiedman registered a domain | Continue reading
We're in Paris! And feeling proper relaxed after several days of wine and cheese too, I might add. This was a very impromptu end of 2023 weekly update as we balanced family time with doing the final video for the year. On the cyber side, the constant theme | Continue reading
It's that time of the year again, time to head from the heat to the cold as we jump on the big plane(s) back to Europe. The next 4 weekly updates will all be from places of varying degrees colder than home, most of them done with | Continue reading
I'd say the balloon fetish segment was the highlight of this week's video. No, seriously, it's a moment of levity in an otherwise often serious industry. It's still a bunch of personal info exposed publicly and that suchs regardless of the nature | Continue reading
10 years later... 🤯 Seriously, how did this thing turn into this?! It was the humblest of beginning with absolutely no expectations of anything, and now it's, well, massive! I'm a bit lost for words if I'm honest, I hope the chat with Charlotte | Continue reading
A decade ago to the day, I published a tweet launching what would surely become yet another pet project that scratched an itch, was kinda useful to a few people but other than that, would shortly fade away into the same obscurity as all the other ones I'd | Continue reading
I'm irrationally excited about the new Prusa 3D printer on order, and I think that's mostly to do with planning for the NDC Oslo talk I plan to do with Elle, my 11-year old daughter. I'm all for getting the kids exposure not just | Continue reading
For a weekly update with no real agenda, we sure did spend a lot of time talking about the ridiculous approach Harvey Norman took to dealing with heavy traffic on Black Friday. It was just... unfathomable. A bunch of people chimed into the tweet thread and suggested it may have | Continue reading
Think about it like this: in 2015, we all lost our proverbial minds at the idea of the Kazakhstan government mandating the installation of root certificates on their citizens' devices. We were outraged at the premise of a government mandating the implementation of a model th … | Continue reading
Allegedly, Acuity had a data breach. That's the context that accompanied a massive trove of data that was sent to me 2 years ago now. I looked into it, tried to attribute and verify it then put it in the "too hard basket" and moved onto | Continue reading
Most of this week's video went on the scraped (and faked) LinkedIn data, but it's the ransomware discussion that keeps coming back to mind. Even just this morning, 2 days after recording this live stream, I ended up on nation TV talking about the DP World | Continue reading
Edit (1 day later): After posting this, the party responsible for leaking the data turned around and said "that was only a small part of it, here's the whole thing", and released records encompassing a further 14M records. I've added those into HIBP and | Continue reading
Yes, the Lenovo is Chinese. No, I'm not worried about Superfish. Yes, I'm running windows. No, I don't want a Framework laptop. Seemed to be a lot of time this week gone on talking all things laptops, and there are clearly some very differing | Continue reading
My mate Lars Klint shared this tweet the other day: Your password is not unique. pic.twitter.com/ga4GwxtzrQ — Lars Klint (@larsklint) April 16, 2017 Naturally, I passed it on because let's face it, that's some crazy shit going on right there. To which the Twitters responde … | Continue reading
How best to punish spammers? I give this topic a lot of thought because I spend a lot of time sifting through the endless rubbish they send me. And that's when it dawned on me: the punishment should fit the crime - robbing me of my time - which means | Continue reading

How many times have you heard the old adage about how nothing in life is free: If you're not paying for the product, you are the productFacebook. LinkedIn. TikTok. But this isn't an internet age thing, the origins go back way further, originally being used to describe TV viewers … | Continue reading
Four and a half years ago now, I rolled out version 2 of HIBP's Pwned Passwords that implemented a really cool k-anonymity model courtesy of the brains at Cloudflare. Later in 2018, I did the same thing with the email address search feature used by Mozilla, 1Password and a handfu … | Continue reading

Earlier today, Have I been pwned (HIBP) appeared on a British TV show called The Martin Lewis Money Show. A producer had contacted me about this last week: I Just wanted to get in contact to let you know we're featuring 'have I been pwned?' on the programme next | Continue reading
Over the last 4 years, I've onboarded 28 national government CERTs onto Have I Been Pwned (HIBP) and given them free and open access to APIs that enable them to query and monitor their gov domains. This doesn't give them access to any information they can't already access via the | Continue reading
I have lots of little ideas for various pet projects, most of which go nowhere (Have I Been Pwned being the exception), so I'm always looking for the fastest, cheapest way to get up and running. Last month as part of my blog post on How Everything We're Told About | Continue reading
I have a vehement dislike for misleading advertising. We see it every day; weight loss pills, make money fast schemes and if you travel in the same circles I do, claims that extended validation (EV) certificates actually do something useful: Why are you still claiming this @digic … | Continue reading
A decade and a bit ago during my tenure at Pfizer, a colleague's laptop containing information about customers, healthcare providers and other vendors was stolen from their car. The machine had full disk encryption and it's not known whether the thief was ever actually able to ac … | Continue reading
In the last month, there were 1,260,000,000 occasions where a service somewhere checked a password against Have I Been Pwned's (HIBP's) Pwned Password API. 99.7% of the time, that check went no further than one of hundreds of Cloudflare edge nodes spread around the world (95% | Continue reading
