It’s a long one this week, in part due to the constant flood of new breaches and disclosures I discuss. I regularly have disclosure notices forwarded to me by followers who find themselves in new breaches, and it’s always fascinating to hear how they’re

The State of Data Breaches, Part 2: The Trilogy of Players

Presently sponsored by: Report URI: Guarding you from rogue JavaScript! Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite

Last week, I wrote about The State of Data Breaches and got loads of feedback. It was predominantly sympathetic to the position I find myself in running HIBP, and that post was mostly one of frustration: lack of disclosure, standoffish organisations, downplaying breaches and the individual breach victims themselves making

Why does it need to be a crazy data breach week right when I’m struggling with jet lag?! I came home from Europe just as a bunch of the Snowflake-sourced breaches started being publicly dumped, and things went a little crazy. Lots of data to review, lots of

The State of Data Breaches

Presently sponsored by: Push Security. Stop identity attacks with a browser-based agent that detects and prevents account takeover. Try it free now.

I’ve been harbouring some thoughts about the state of data breaches over recent months, and I feel they’ve finally manifested themselves into a cohesive enough story to write down. Parts of this story relate to very sensitive incidents and parts to criminal activity, not just on

Presently sponsored by: 1Password Extended Access Management: Secure every sign-in for every app on every device.

Last week, a security researcher sent me 122GB of data scraped out of thousands of Telegram channels. It contained 1.7k files with 2B lines and 361M unique email addresses of which 151M had never been seen in HIBP before. Alongside those addresses were passwords and, in many cases, the

Ah, episode 401, the unauthorised one! Ok, that was terrible, but what’s not terrible is finally getting some serious dev resources behind HIBP. I touch on it in the blog post but imagine all the different stuff I have to spread myself across to run this thing, and

Have I Been Pwned Employee 1.0: Stefán Jökull Sigurðarson

Presently sponsored by: Report URI: Guarding you from rogue JavaScript! Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite

We often do that in this industry, the whole “1.0” thing, but it seems apt here. I started Have I Been Pwned (HIBP) in 2013 as a pet project that scratched an itch, so I never really thought of myself as an “employee”. Over time,
