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. However, per that story: Cybernews couldn’t confirm the authenticity of the data. We reached out to Accor for clarification and are awaiting a response. I couldn't confirm the authenticity of the data either and I wro...

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 for AT&T (in my non-legal but "hey, I'm the data breach guy" opinion), will be their denial of a breach in 2021 and the subsequent years in which tens of millions of social security numbers were floating around. As much as it's hard for the victim...

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, we have one of the highest rates of skin cancer in the world with apparently about two-thirds of us being diagnosed with it before turning 70. At present, the bits they cut off me were entirely unremarkable (small dot about an inch over my left eye if you're reall...

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 during the live stream and according to the AI, it's permissible "when properly quoted": "john|doe"@example.com Give that a go and see how far you get in an input of type "email". Mind you, that example allows a pipe wh...

I hate having to use that word - "alleged" - because it's so inconclusive and I know it will leave people with many unanswered questions. (Edit: 12 days after publishing this blog post, it looks like the "alleged" caveat can be dropped, see the addition at the end of the post for more.) But sometimes, "alleged" is just where we need to begin and over the course of time, proper attribution is made and the dots are joined. We're here at "alleged" for two very simple reasons: one is that AT&T is sa...

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 around now...?" The weeks leading up to this trip were especially chaotic and to be honest, I simply forgot all about work once we landed here. And when you see the pics in the thread below, you'll understand why: Tokyo time! 🍣 pic.twitter.com/dG0...

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 Security Unit who now have full access to their government domains. We provide this support to governments to help those tasked with protecting their national interests understand more about the threats posed by data breaches, and we loo...

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 "fast, good and cheap - pick 2" saying, but there's a lot more nuance to it than that, of course. I mean Table Storage was all 3 of those, just so long as we never needed to restore at all, let alone to a point in time. Or geo-replicate. Or do ad hoc queries an...

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 service, courtesy of their CERTBund department. This access now provides them with complete access to the exposure of their government domains in data breaches. With the unabated flood of data breaches, we're happy to provide this...

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 here" claim that I find particularly fascinating; the truth is always sitting there in the data and it doesn't take much to bring it to the surface. Ah well, as I always end up lamenting, with behaviour like this it's a good time to be in...
