Security

It's finally time: it's time the pendulum swings further towards the "secure by default" end of the scale than what it ever has before. At least insofar as securing web traffic goes because as of this week's Chrome 62's launch, any website with an input box is now doing this when served over an insecure connection: It's not doing it immediately for everyone [https://textslashplain.com/2017/10/18/chrome-field-trials/], but don't worry, it's coming very soon even if it hasn't yet arrived for yo...

A couple of years ago, I was heavily involved in analysing and reporting on the massive VTech hack [https://www.troyhunt.com/when-children-are-breached-inside/], the one where millions of records were exposed including kids' names, genders, ages, photos and the relationship to parents' records which included their home address. Part of this data was collected via an IoT device called the InnoTab which is a wifi connected tablet designed for young kids; think Fisher Price designing an iPad... th...

We all jumped on "the Equifax dumpster fire bandwagon" recently and pointed to all the things that went fundamentally wrong with their disclosure process. But it's equally important that we acknowledge exemplary handling of data breaches when they occur because that's behaviour that should be encouraged. Last week, someone reached out and shared a number of data breaches with me. Breaches I'd never seen before. Some of them were known by the companies who'd previously made public disclosures; R...

I was wondering recently after poring through yet another data breach how many people actually use multi-step verification. I mean here we have a construct where even if the attacker has the victim's credentials, they're rendered useless once challenged for the authenticator code or SMS which is subsequently set. I went out looking for figures and found the following on Dropbox: > "less than 1% of the Dropbox user base is taking advantage of the company’s two-factor authentication feature": htt...

Last week I was contacted by someone alerting me to the presence of a spam list. A big one. That's a bit of a relative term though because whilst I've loaded "big" spam lists into Have I been pwned (HIBP) before [https://www.troyhunt.com/have-i-been-pwned-and-spam-lists-of-personal-information/], the largest to date has been a mere 393m records and belonged to River City Media [https://haveibeenpwned.com/PwnedWebsites#RiverCityMedia]. The one I'm writing about today is 711m records which makes i...

As best I understand it, one of the most effective SEO things you can do is to repeat all the important words on your site down the bottom of the page. To save it from looking weird, you make the text the same colour as the background so people can't actually see it, but the search engines pick it up. Job done, profit! I think this is the way we did it in 1999. I don't know, I can't recall exactly, but I know I don't know and I'll happily admit to being consciously incompetent in the ways of SE...

Edit 1: The following day, I loaded another set of passwords which has brought this up to 320M. More on why later on. Edit 2: The API model described below has subsequently been discontinued [https://www.troyhunt.com/enhancing-pwned-passwords-privacy-by-exclusively-supporting-anonymity/] in favour of the k-anonymity model [https://www.troyhunt.com/ive-just-launched-pwned-passwords-version-2/] launched with V2. Last week I wrote about Passwords Evolved: Authentication Guidance for the Modern E...

Only a couple of months ago, I did a talk titled "The Responsibility of Disclosure: Playing Nice and Staying Out of Prison". The basic premise was to illustrate where folks finding security vulnerabilities often go wrong in their handling of the reporting, but I also wanted to show how organisations frequently make it very difficult to responsibly disclose the issue in the first place. Just for context, I suggest watching a few minutes of the talk from the point at which I've set the video below...

In the beginning, things were simple: you had two strings (a username and a password) and if someone knew both of them, they could log in. Easy. But the ecosystem in which they were used was simple too, for example in MIT's Time-Sharing Computer [https://www.wired.com/2012/01/computer-password/], considered to be the first computer system to use passwords: We're talking back in the 60's here so a fair bit has happened since then. Up until the last couple of decades, we had a small number of...

Last week I wrote about how Life Is About to Get a Whole Lot Harder for Websites Without HTTPS [https://www.troyhunt.com/life-is-about-to-get-harder-for-websites-without-https/]. Somewhere in the comments there, the discussion went off on a tangent about commercial CAs, the threat Let's Encrypt poses to them and subsequently, the value (or lack thereof) posed by extended validation (EV) certificates. That discussion boiled over onto Twitter with many vocal opinions from different camps. This pos...
