You Don't Need to Burn off Your Fingertips (and Other Biometric Authentication Myths)

111 years ago almost to the day, a murder was committed which ultimately led to the first criminal trial to use fingerprints as evidence. We've all since watched enough crime shows to understand that fingerprints are unique personal biometric attributes and to date, no two people have ever been found to have a matching set. As technology has evolved, fingers (and palms and irises and faces) have increasingly been used as a means of biometric authentication. I'm writing this on a PC that uses a Verifi fingerprint reader. I'll probably continue to draft it from a comfy spot later on using my Lenovo laptop that has a built in reader. I'll also go backwards and forward between my iPhone and...

Hello CISO - Brought to You in Collaboration with 1Password

Today I'm really excited to announce a big piece of work 1Password and I have been focusing on this year, a totally free video series called "Hello CISO". This is a multi-part series that launched with part 1 and when I say "free", I don't mean "give us your personal data so we can market to you", I mean here it is, properly free: This is intended to be a very practical, broadly accessible series and whilst it has "CISO" in the title, we expect it'll be relevant well beyond the pointy end of the infosec ladder. Part 1 on the downfall of on-prem security is a perfect example of that; all of us in the industry have heard the...

Why No HTTPS? The 2021 Version

More than 3 years ago now, Scott Helme and I launched a little project called Why No HTTPS? It listed the world's largest websites that didn't properly redirect insecure requests to secure ones. We updated it December before last and pleasingly, noted that more websites than ever were doing the right thing and forcing browsers down the secure path. That's the good news, the bad news is that there are still some really wacky, unexplainable anti-HTTPS views out there, but those voices are increasingly less relevant as the browsers march forward: Beginning in M94, Chrome will offer HTTPS-First Mode, which will attempt to upgrade all page loads to HTTPS and display a full-page warning before loading sites that don’t...

Data Breaches, Class Actions and Ambulance Chasing

This post has been brewing for a while, but the catalyst finally came after someone (I'll refer to him as Jimmy) recently emailed me regarding the LOQBOX data breach from 2020. Their message began as follows: I am currently in the process of claiming compensation for a severe data breach which occurred on the 20th February 2020Now I'll be honest - I had to Google this one. There are so many data breaches today that I have trouble keeping track of them and there was nothing noteworthy whatsoever about this one that caused it to stick in my memory. Turns out there were a bunch of tweets mentioning me in this context in Feb 2020, but that was all. The...

I Now Own the Coinhive Domain. Here's How I'm Fighting Cryptojacking and Doing Good Things with Content Security Policies.

If you've landed on this page because you saw a strange message on a completely different website then followed a link to here, drop a note to the site owner and let them know what happened. If, on the other hand, you're on this page because you're interested in reading about the illicit use of cryptomining on compromised websites and how through fortuitous circumstances, I now own coinhive.com and am doing something useful with it, read on. You know how people don't like ads? Yeah, me either (at least not the spammy tracky ones that invade both your privacy and your bandwidth), but I also like free content on the web and therein lies the rub; how do content...

Gab Has Been Breached

I've investigated hundreds of data breaches over the years (there are 514 of them in Have I Been Pwned as I write this), and for the most part, the situation with Gab is just another day on the internet. But Gab is also different, having grown dramatically in recent months as an alternative to mainstream incumbent platforms such as Twitter and Facebook and drawing a crowd primarily focused on right wing American politics. A couple of days ago, I posted a thread about their alleged breach. I want to go back through that thread here, explain the thinking further and then provide some commentary on the actual data that was exposed. It all began here: So, the @getongab data breach...

IoT Unravelled Part 3: Security

In part 1 of this series, I posited that the IoT landscape is an absolute mess but Home Assistant (HA) does an admirable job of tying it all together. In part 2, I covered IP addresses and the importance of a decent network to run all this stuff on, followed by Zigbee and the role of low power, low bandwidth devices. I also looked at custom firmware and soldering and why, to my mind, that was a path I didn't need to go down at this time. Now for the big challenge - security. As with the rest of the IoT landscape, there's a lot of scope for improvement here and also just like the other IoT posts, it gets...

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...

I've Joined the 1Password Board of Advisers

Almost a decade ago now, I wrote what would become one of my most career-defining blog posts: The Only Secure Password is the One You Can't Remember. I had come to the realisation that I simply had too many accounts across too many systems to ever have any chance of creating decent unique passwords I could remember. So, I set out to find a password manager and 10 Christmas holidays ago now, I spent the best 50 bucks ever: I chose 1Password way back then and without a shadow of a doubt, it has become one of the most important pieces of software I have ever used. Since that date in 2011, I doubt there's been a single day I...

Humans are Bad at URLs and Fonts Don’t Matter

Been a lot of "victim blaming" going on these last few days. The victim, through no fault of their own, has been the target of numerous angry tweets designed to ridicule their role in internet security and suggest they are incapable of performing their duty. Here's where it all started: This is a great example of how bad people are at reading and understanding even the domain part of the URL then making decisions based on that which affect their security and privacy (see the answer under the poll) https://t.co/Ati2ndKvGI — Troy Hunt (@troyhunt) October 24, 2020 Let me include a screen grab of the poll NordVPN posted in that tweet because for reasons that will become...
