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...

Hacking Grindr Accounts with Copy and Paste

Sexuality, relationships and online dating are all rather personal things. They're aspects of our lives that many people choose to keep private or at the very least, share only with people of our choosing. Grindr is "The World's Largest Social Networking App for Gay, Bi, Trans, and Queer People" which for many people, makes it particularly sensitive. It's sensitive not just because by using the site it implies one's sexual orientation, but because of the sometimes severe ramifications of fitting within Grindr's target demographic. For example, in 2014 Egypt's police were found to be using Grindr to "trap gay people" which was particularly concerning in a country not exactly up to speed with LGBT equality. Another demonstration of how valuable...

Padlocks, Phishing and Privacy; The Value Proposition of a VPN

I want a "secure by default" internet with all the things encrypted all the time such that people can move freely between networks without ever needing to care about who manages them or what they're doing with them. I'm a massive proponent of Let's Encrypt's and Cloudflare's missions to secure the web and of browser paradigms such as HSTS and upgrade-insecure-requests via content security policies to help make it a reality. Yet I also find myself constantly using VPNs for a variety of security and privacy related reasons and it got me thinking - why? I mean what's the remaining gap? Last month I announced I've partnered with NordVPN as a strategic adviser and as part of that effort, I...

We Didn't Encrypt Your Password, We Hashed It. Here's What That Means:

You've possibly just found out you're in a data breach. The organisation involved may have contacted you and advised your password was exposed but fortunately, they encrypted it. But you should change it anyway. Huh? Isn't the whole point of encryption that it protects data when exposed to unintended parties? Ah, yes, but it wasn't encrypted it was hashed and therein lies a key difference: Saying that passwords are “encrypted” over and over again doesn’t make it so. They’re bcrypt hashes so good job there, but the fact they’re suggesting everyone changes their password illustrates that even good hashing has its risks. https://t.co/21V6Vte6Wa — Troy Hunt (@troyhunt) September 2, 2020 I see this over...

I'm Partnering with NordVPN as a Strategic Advisor

I love security. I love privacy. Consequently, it will come as no surprise that I love tools that help people achieve those objectives. Equally, I have no patience for false promises, and I've been very vocal about my feelings there: But one of them is literally called “Secure VPN”, how is this possible?! “Are You Using These VPN Apps? Personal Info Of 20 Million Users Leaked: That’s 1.2TB Data” https://t.co/BPDww70Pgo — Troy Hunt (@troyhunt) July 20, 2020 VPNs are a great example of where a tool can be used to enhance security and privacy but often, they fall short of delivering on the promise. When you use a VPN, you're trusting a third party with...

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...

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...
