Sometimes the discussion around extended validation certificates (EV) feels a little like flogging a dead horse. In fact, it was only September that I proposed EV certificates are already dead [https://www.troyhunt.com/extended-validation-certificates-are-dead/] for all sorts of good reasons that have only been…
It's finally time: it's time the pendulum swings further towards the "secure by default" end of the scale than what it ever has before. At least insofar as securing web traffic goes because as of this week's Chrome 62's launch, any website with an input box
This content is now available in the Pluralsight course "Secure Account Management Fundamentals" [http://www.pluralsight.com/courses/secure-account-management-fundamentals] Recently I’ve had a couple of opportunities to think again about how a secure password reset function should operate, firstly whilst building this…
tl;dr - a collection of nearly 3k alleged data breaches has appeared with a bunch of data already proven legitimate from previous incidents, but also tens of millions of addresses that haven't been seen in HIBP before. Those 80M records are now searchable, read on for the full story:
It's fascinating to see how creative people can get with breached data. Of course there's all the nasty stuff (phishing, identity theft, spam), but there are also some amazingly positive uses for data illegally taken from someone else's system. When I first built Have I Been Pwned
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 @digicert [https://twitter.com/
Many people will disagree with this post, not so much because it's flat out wrong but because there are so many different approaches one can take. It's a very subjective realm but I'm going to put forward some suggestions, make some considered arguments and leave it at
Back in August, I pushed out a service as part of Have I Been Pwned [https://haveibeenpwned.com/] (HIBP) to help organisations block bad passwords from their online things. I called it "Pwned Passwords" and released 320M of them from real-world data breaches [https://www.troyhunt.com/introducing-306-
That's it - I'm calling it - extended validation certificates are dead. Sure, you can still buy them (and there are companies out there that would just love to sell them to you!), but their usefulness has now descended from "barely there" to "as good as non-existent". This change
Let me make it crystal clear in the opening paragraph: this incident is not about any sort of security vulnerability on GitHub's behalf, rather it relates to a trove of data from their site which was inappropriately scraped and then inadvertently exposed due to a vulnerability in another service.
Allow me to be controversial for a moment: arbitrary password restrictions on banks such as short max lengths and disallowed characters don't matter. Also, allow me to argue with myself for a moment: banks shouldn't have these restrictions in place anyway. I want to put forward cases for
So the Sony saga continues. As if the whole thing about 77 million breached PlayStation Network accounts [http://www.theage.com.au/digital-life/games/playstation-privacy-breach-77-million-customer-accounts-exposed-20110427-1dvhf.html] wasn’t bad enough, numerous other security breaches…
Do you ever hear those stories from your parents along the lines of "when I was young..." and then there's a tale of how risky life was back then compared to today. You know, stuff like having to walk themselves to school without adult supervision, crazy stuff like that
A few months back I got a call one evening which was clearly a virus call centre scam; you know, the ones that call you out of the blue, tell you your PC is infected with all sorts of nasties and offer to fix it for you? Or maybe you
We all jumped on "the Equifax dumpster fire bandwagon" recently and pointed to all the things that went fundamentally wrong with their disclosure process. But it's equally important that we acknowledge exemplary handling of data breaches when they occur because that's behaviour that should be encouraged. Last week,
It seems that there is no limit to human ingenuity when it comes to working around limitations within one's environment. For example, imagine you genuinely wanted to run a device requiring mains power in the centre of your inflatable pool - you're flat out of luck, right? Wrong! Or
I'll start this post where I start many of my talks - what does a hacker look like? Or perhaps more specifically, what do people think a hacker looks like? It's probably a scary image, one that's a bit mysterious, a shady character lurking in the hidden depths
In the beginning, there was the web and you accessed it though the browser and all was good. Stuff didn’t download until you clicked on something; you expected cookies to be tracking you and you always knew if HTTPS was being used. In general, the casual observer had a
I get a lot of requests from people for data from Have I been pwned [https://haveibeenpwned.com/] (HIBP) that they can analyse. Now obviously, there are a bunch of people up to no good requesting the data but equally, there are many others who just want to run statistics.
The short version: I'm loading over 1 billion breached accounts into HIBP. These are from 2 different "combo lists", collections of email addresses and passwords from all sorts of different locations. I've verified their accuracy (including my own record in one of them) and many hundreds of millions
Almost one year ago now, I declared extended validation certificates dead [https://www.troyhunt.com/extended-validation-certificates-are-dead/]. The entity name had just been removed from Safari on iOS, it was about to be removed from Safari on Mojave and there were indications that Chrome would remove it
I got a rather odd invoice via PayPal the other day, it looks like this: Naturally the first thing I did was to look for spoof email indicators, but none of the usual suspects were showing up: 1. It was from member@paypal.com.au 2. The mail headers were
Last week I wrote about how Life Is About to Get a Whole Lot Harder for Websites Without HTTPS [https://www.troyhunt.com/life-is-about-to-get-harder-for-websites-without-https/]. Somewhere in the comments there, the discussion went off on a tangent about commercial CAs, the threat

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't Hacked blog post
Yesterday I had a bunch of people point me at a tweet from a politician in the UK named Nadine Dorries [https://twitter.com/NadineDorries]. As it turns out, some folks were rather alarmed about her position on sharing what we would normally consider to be a secret. In this
It happened again last week. No, not Yahoo! Voices [https://www.troyhunt.com/2012/07/what-do-sony-and-yahoo-have-in-common.html], not the Phandroid Android forums [http://www.zdnet.com/android-forums-hacked-1-million-user-credentials-stolen-7000000817/] , not NVidia [http://www.zdnet.com/nvidia-confirms-
The first time I ever wrote publicly about a company's security vulnerabilities, my boss came to have a word with me after seeing my name in the news headlines. One of the worst days I've ever had was right in the middle of the Have I Been Pwned
I’ve been considering purchasing one of these t-shirts: This shirt would announce to everyone who crosses my path that I am, in fact, the world’s greatest lover. They would know this because I have a t-shirt that tells them so and it would give them enormous
It’s a bit hard to even know where to begin with this one, perhaps at the start and then I’ll try and piece all the bits together as best I can. As you may already know if you’re familiar with this blog, I run the service Have
