Have I Been Pwned

Inside the Cit0Day Breach Collection

It's increasingly hard to know what to do with data like that from Cit0Day. If that's an unfamiliar name to you, start with Catalin Cimpanu's story on the demise of the service followed by the subsequent leaking of the data. The hard bit for me is figuring out whether it's pwn-worthy enough to justify loading it into Have I Been Pwned (HIBP) or if it's just more noise that ultimately doesn't really help people make informed decisions about their security posture. More on that shortly, let's start with what's in there and we're looking at a zip file named "Cit0day.in_special_for_xss.is.zip" that's 13GB when compressed: A couple of folders down are two more folders named...

Welcoming the Canadian Government to Have I Been Pwned

Following in the footsteps of many other national governments before them, I'm very happy to welcome the Canadian Centre for Cyber Security to Have I Been Pwned. The Canadian Centre for Cyber Security now has full and free access to query all Canadian federal government domains across both past and future breaches. Canada's inclusion in the service brings the total to 11 federal governments across North America, Europe and Australia. I hope to include more parts of the world in the coming months....

I'm Open Sourcing the Have I Been Pwned Code Base

Let me just cut straight to it: I'm going to open source the Have I Been Pwned code base. The decision has been a while coming and it took a failed M&A process to get here, but the code will be turned over to the public for the betterment of the project and frankly, for the betterment of everyone who uses it. Let me explain why and how. HIBP is a Community ProjectI've been giving a great deal of thought to how I want this project to evolve lately, especially in the wake of the M&A process that ended earlier this year right back where I'd started: with me being solely responsible for everything. The single...

How BeerAdvocate Learned They'd Been Pwned

I love beer. This comes as no surprise to regular followers, nor should it come as a surprise that I maintain an Untappd account, logging my beer experiences as I (used to 😢) travel around the world partaking in local beverages. When I received an email from someone over that way who happened to be a happy Have I Been Pwned (HIBP) user and wanted some cyber-assistance, I was intrigued. You'll never believe what happened next... The tl;dr is that someone with a BeerAdvocate account was convinced the service had been pwned as they'd seen evidence of an email address and password they'd used on the service being abused. They reached out to my guy (we'll call him that for...

10B

Nearly 7 years ago now, I started a little pet project to index data breaches and make them searchable. I called it "Have I Been Pwned" and I loaded in 154M breached records which to my mind, was rather sizeable. Time went by, the breaches continued and the numbers rose. A few years later in June 2016 on stage at NDC Oslo, I pushed HIBP through 1B records: Whoa, we're there, past a billion!There was much applause which I countered with "is it a joyous moment, because it's kinda sad as well?" But what's even sadder than 1B breached records is 10B breached records: New data breach now loading into @haveibeenpwned that'll push it *well* over 10,...

Pwned Passwords, Version 6

Today, almost one year after the release of version 5, I'm happy to release the 6th version of Pwned Passwords. The data set has increased from 555,278,657 known compromised passwords to a grand total of 572,611,621, up 17,332,964‬ (just over 3%). As with previous releases, I've made the call to push the data now simply because there were enough new records to justify the overhead in doing so. Also as with previous releases, version 6 not only introduces a heap of new records but also updates the prevalence count on the existing ones. For example, the old favourite "P@55w0rd" has gone from 2,929 occurrences to 3,069 so still a terrible password,...

The Unattributable "Lead Hunter" Data Breach

Pwned again. Damn. That's me who's pwned again because my personal data has just turned up in yet another incident from a source I can't attribute. Less than 3 weeks ago I wrote about The Unattributable "db8151dd" Data Breach which, after posting that blog post and a sample of my own data, the community quickly attributed to Covve. My hope is that this blog post helps myself and the 69 million other people in this one work out who collected and then exposed their personal information. So, data first, here's what they have on me: Similar deal to last time in that it was an exposed Elasticsearch instance and it was sent over to me by Dehashed. Turns out it's...

Analysing the (Alleged) Minneapolis Police Department "Hack"

The situation in Minneapolis at the moment (and many other places in the US) following George Floyd's death is, I think it's fair to say, extremely volatile. I wouldn't even know where to begin commentary on that, but what I do have a voice on is data breaches which prompted me to tweet this out earlier today: I'm seeing a bunch of tweets along the lines of "Anonymous leaked the email addresses and passwords of the Minneapolis police" with links and screen caps of pastes as "evidence". This is almost certainly fake for several reasons: — Troy Hunt (@troyhunt) May 31, 2020 I was CC'd into a bunch of threads that were redistributing the...

The Unattributable "db8151dd" Data Breach

I was reticent to write this blog post because it leaves a lot of questions unanswered, questions that we should be able to answer. It's about a data breach with almost 90GB of personal information in it across tens of millions of records - including mine. Here's what I know: Back in Feb, Dehashed reached out to me with a massive trove of data that had been left exposed on a major cloud provider via a publicly accessible Elasticsearch instance. It contained 103,150,616 rows in total, the first 30 of which look like this: The global unique identifier beginning with "db8151dd" features heavily on these first lines hence the name I've given the breach. I've had to give...

Welcoming the Icelandic Government to Have I Been Pwned

Hot on the heels of onboarding the USA government to Have I Been Pwned last month, I'm very happy to welcome another national government - Iceland! As of today, Iceland's National Computer Security Incident Response Team (CERT-IS), now has access to the full gamut of their gov domains for both on-demand querying and ongoing monitoring. As with the USA and Iceland, I expect to continue onboarding additional governments over the course of 2020 and expanding their access to meaningful data about breaches that impact their departments....
