This content is now available in the Pluralsight course "Understanding the Shellshock Bash Bug" [http://www.pluralsight.com/courses/shellshock-bash-bug]Remember Heartbleed [https://www.troyhunt.com/2014/04/everything-you-need-to-know-about.html]? If you believe the hype today, Shellshock is in that league and with an equally awesome name albeit bereft of a cool logo (someone in the marketing department of these vulns needs to get on that). But in all seriousness, it does have the potential to be...

These real world experiences with Azure are now available in the Pluralsight course "Modernizing Your Websites with Azure Platform as a Service" [http://www.pluralsight.com/courses/modernizing-websites-microsoft-azure]This is not what you want to see on your Azure website: Ok, so what are we looking at here? CPU goes up and up and up and then… dramatically down. There are even some additional coloured lines in the middle of that graph indicating that there were more instances put on just to d...

No, I didn’t camp out the front of the Apple store with my sleeping bag and frankly, I think those that did perhaps have what we refer to down here as “a couple of kangaroos loose in the top paddock”. Queues stretching hundreds of metres and adults in tears [http://www.smh.com.au/digital-life/mobiles/student-in-tears-after-being-kicked-out-of-iphone-6-queue-20140919-10j7uq.html] aren’t really my things (incidentally, crying over queue position is not something you do once you have your grown up...

I’ve got 174,451,409 breached accounts in Have I been pwned? [https://haveibeenpwned.com/] (HIBP) as of today which probably sounds like a lot, but it’s not. Why is it not a lot? Because whilst that list spans a lot of the big breaches I could get my hands on, as of the middle of this year (now a couple of months ago already), there were over half a billion accounts breached in just six months [https://www.riskbasedsecurity.com/2014/08/hacking-exposed-78-of-all-records-compromised-in-first-half-...

These real world experiences with Azure are now available in the Pluralsight course "Modernizing Your Websites with Azure Platform as a Service" [http://www.pluralsight.com/courses/modernizing-websites-microsoft-azure]This is the traffic pattern that cloud pundits the world over sell the value proposition of elastic scale on: This is Have I been pwned? [https://haveibeenpwned.com] (HIBP) going from a fairly constant ~100 sessions an hour to… 12,000 an hour. Almost immediately. This is what h...

You may not know this, but an HTTP 403 response when browsing to an empty directory is a serious security risk. What the?! You mean if I go to my website which has a “scripts” folder where I put all my JavaScript and I have directory browsing disabled (as I rightly should) and the server returns a 403 “Forbidden” (which it rightly should), I’m putting my internet things at risks of being pwned?! Yes, because it discloses the presence of a folder called “scripts” which is a common directory. W...

I’ve long held the view that passwords should consist of as many crazy things as the owner deems fit. If I want to create a password that looks like a dog just ate the keyboard and threw up all the keys, then good for me. (Chances are that Fido is going to cough up a pretty unique password too but before PETA gets on my case, try using a password manager like 1Password [https://www.troyhunt.com/2011/03/only-secure-password-is-one-you-cant.html] instead.) Now I’m used to seeing all sorts of ridi...

A few years ago I was taking a look at the inner workings of some mobile apps on my phone. I wanted to see what sort of data they were sending around and as it turned out, some of it was just not the sort of data that should ever be traversing the interwebs in the way it was. In particular, the Westfield iPhone app to find your car caught my eye [https://www.troyhunt.com/2011/09/find-my-car-find-your-car-find.html]. A matter of minutes later I had thousands of numberplates for the vehicles in th...

I will not run web security analysers without first understanding web security. I will not run web security analysers without first understanding web security. I will not run web security analysers without first understanding web security. Are we clear now? Good, because as neat as tools like I’m about to discuss are, nothing good comes from putting them in the hands of people who can’t properly interpret the results and grasp the concepts of what dynamic analysis scanners can and cannot cover....

I know I’ve shared this a number of times now, but no matter how much I see it, it still cracks me up: [https://www.troyhunt.com/2012/07/lessons-in-website-security-anti.html] Make sense? Of course it doesn’t and therein lies the insanity of it all! But let us not single out Tesco alone, there are plenty of British companies that construct responses like this (sorry English people, I don’t know why, they just seem to feature disproportionately to the rest of the world). In fact earlier this w...
