Have I Been Pwned

In running Have I been pwned? (HIBP) [https://haveibeenpwned.com/], I often get asked – “Can I trust you with my email address?” – which I find to be a very odd question. It’s odd because for the most part, we never really think about how trustworthy a website is before we enter the address. What I mean by this is that we all sign up for dozens if not hundreds of services ranging from shopping to social to professional and enter a whole heap of data, including our email address all the time. We...

If you’re reading this, it’s possible I directed you here with little more than a mere URL in my reply to you. It’s likely that you asked for data that has been breached from an online system. Perhaps it was your data you asked for, perhaps it was other people’s data you were seeking but regardless, the response is the same. No, I cannot. In running Have I been pwned? [https://haveibeenpwned.com/] (HIBP) I obviously come across a lot of data breaches with a lot of sensitive data. I understand t...

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 I been pwned? [https://haveibeenpwned.com/] (HIBP) which allows people to discover where their personal data has been compromised on the web. When a breach hits the public airwaves, I load in the email addresses and those who subscribe to the service (it’s free) get noti...

I’m a big proponent of the content security policy paradigm (CSP) supported by modern browsers. In fact I’m so keen on them I even wrote a Pluralsight course: Introduction to Browser Security Headers [http://www.pluralsight.com/courses/browser-security-headers]. (Sidenote: I’m enormously happy with how well this course has been received, seems there’s an appetite for securing our things after all!) Now if you’re not sure what all the fuss is about, have a quick read of my launch blog post for...

I’ve always written very publicly about how Have I been pwned [https://haveibeenpwned.com/] (HIBP) was conceived, built and indeed how it performs. If ever there was a time to look back at that performance, it’s in the wake of the first few days after loading in the Ashley Madison breach. I want to share the “warts and all account” of what I observed over the three days of utter chaos that ensued. I first learned of the incident at about 6am local on Wednesday which was very shortly after the t...

To date, I’ve avoided commenting on the other Ashley Madison search services and have invested my efforts purely in keeping Have I been pwned? [https://haveibeenpwned.com/] (HIBP) ticking along. I’ve seen them come and indeed I’ve seen some of them go too. I’ve seen many that enable you to get confirmation about the presence of an email in Ashley Madison, others that return everything about the user. Publicly. To anyone. But something I saw today struck a very different chord with me, something...

I found myself in somewhat of a unique position last week: I’d made the Ashley Madison data searchable for verified subscribers of Have I been pwned? [https://haveibeenpwned.com/] (HIBP) and now – perhaps unsurprisingly in retrospect – I was being inundated with email. I mean hundreds of emails every day with people asking questions about the data. Not just asking questions, but often giving me their life stories as well. These stories shed a very interesting light on the incident, one that mos...

This was always going to be a huge incident given not just the scale of the number of accounts impacted by the Ashley Madison breach [https://krebsonsecurity.com/2015/08/was-the-ashley-madison-database-leaked/] (well over 30M), but the sensitivity of the data within it. However the interest has surprised even me – I loaded the breached data into Have I been pwned? [https://haveibeenpwned.com/] (HIBP) about 8 hours ago and I’m presently seeing about 30k visitors an hour to the site. I’ve had a c...

I’ve often received feedback from people about this SSL Labs test of Have I been pwned? [https://haveibeenpwned.com/] (HIBP): Just recently I had an email effectively saying “drop this cipher, do that other thing, you’re insecure kthanksbye”. Precisely what this individual thought an attacker was going to do with an entirely public site wasn’t quite clear (and I will come back to this later on), but regardless, if I’m going to have SSL then clearly I want good SSL and this report bugged me....

This morning I was reading a piece on the Ashley Madison hack [http://www.inquisitr.com/2281408/ashley-madison-hack-customer-service-impact-team-complaints-was-he-on-ashley-madison-site-down-as-users-turn-to-private-investigators/] which helped cement a few things in my mind. The first thing is that if this data ends up being made public (and it’s still an “if”) then it will rapidly be shared far and wide. Of course this happens with many major data breaches, but the emergence already of domain...
