Have I Been Pwned

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. Regardless, the answer has always been "no", I'm not going to redistribute data to you. In fact, the requests were happening so frequently that I even wrote the blog post No, I cannot share data breaches with you [https://www.t...

Earlier today, Have I been pwned [https://haveibeenpwned.com/] (HIBP) appeared on a British TV show called The Martin Lewis Money Show [http://www.moneysavingexpert.com/]. 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 week (Monday 28 Nov, 8pm, ITV) saying it's a good way to check if your data has been compromised. I thought it best to let you know in case you need to put extra resour...

It's hard to believe it, but Sunday 4 December will mark 3 years since I launched Have I been pwned [https://www.troyhunt.com/introducing-have-i-been-pwned/]. A huge amount has happened in that time, not just for HIBP but for the industry and indeed for me personally. I certainly didn't expect it to become what it is, not in terms of the amount of data or the number of people visiting and subscribing and certainly not the media attention it's drawn from all over the world. That's posed some real...

One of the things I'm finding with running Have I been pwned [https://haveibeenpwned.com/] (HIBP) is that over time, my approach is changing. Nothing dramatic thus far, usually just what I'd call "organic" corrections in direction and usually in response to things I've learned, industry events or changes in the way people are using the service. For example, the Ashley Madison hack led to the concept of a sensitive breach [https://www.troyhunt.com/heres-how-im-going-to-handle-ashley/] which meant...

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. My data. Probably your data if you're in the software industry. Millions of people's data. On Saturday, a character in the data trading scene popped up and sent me a 594MB file called geekedin.net_mirr...

I have multiple Yahoo data breaches. I have a Twitter data breach. I have Facebook data breaches. I know they are data breaches from those sources because people told me they are, ergo, they're data breaches. Except they're not - they're all fake. Problem is though, fake data breaches don't make for a very good headline nor do they give you something worth trading; for many people, it's not in their best interests to establish what's fake and what's not. Earlier this year I wrote about how I ve...

We're now going on almost 3 years since I introduced the Have I been pwned (HIBP) API [https://www.troyhunt.com/have-i-been-pwned-you-can-now-ask-api/]. In fact it was one of the first things I did after creating HIBP in the first place because I wanted to make the data as accessible as possible and create an ecosystem of third party apps. However, over time I've also had to deal with the API being used in ways I never intended. For example, I recently introduced the rate limit [https://www.tro...

I wrote recently about how Have I been pwned (HIBP) had an API rate limit introduced and then brought forward [https://www.troyhunt.com/content-images-2016-09-a-one-week-traffic-snapshot-1-png/] which was in part a response to large volumes of requests against the API. It was causing sudden ramp ups of traffic that Azure couldn't scale fast enough to meet and was also hitting my hip pocket as I paid for the underlying infrastructure to scale out in response. By limiting requests to one per every...

Three weeks ago today, I wrote about implementing a rate limit on the Have I been pwned (HIBP) API [https://www.troyhunt.com/the-have-i-been-pwned-api-rate-limiting-and-commercial-use/] and the original plan was to have it begin a week from today. I want to talk more about why the rate limit was required and why I've had to bring it forward to today. As I explained in the original post, there were multiple reasons for the rate limit including high volumes of API calls impacting system performan...

Earlier today, Motherboard reported on what had been rumoured for some time, namely that Dropbox had been hacked [http://motherboard.vice.com/read/hackers-stole-over-60-million-dropbox-accounts] . Not just a little bit hacked and not in that "someone has cobbled together a list of credentials that work on Dropbox" hacked either, but proper hacked to the tune of 68 million records. Very shortly after, a supporter of Have I been pwned [https://haveibeenpwned.com] (HIBP) sent over the data which o...
