An Anatomy Of A Hack – Weak ROOT Password

So a peaceful Sunday night, I get an odd bandwidth warning for a development/testing server that a developer recently created. It was doing some fairly immense traffic, peaking at 80mb a second and averaging about 8mb/s – definitely not normal. I tried to access the server via SSH but couldn’t connect at all, port 22 […]

An Introduction To Information Security – OpenCoffeeClubKL #31

So I gave a talk about infosec stuff in July at OpenCoffeeClub KL, as it’s what I used to do for a living – people were always asking me to share a little more about it. The timing is a little odd again, as it happens. In 2011 I did 2 talks in the same […]

Building Scalable Web Apps – LVL.UP KL – July 2014

So the most recent LVL.UP KL meeting was about Internet Architecture (my speciality! yay) – and we had an amazing line-up of speakers – plus me. It wasn’t my most coherent talk, due to my wife just giving birth (7 weeks early..) – so I was pretty tired and did the slides at 5am – […]

Yah I Got Hacked – Facebook & Hotmail – Don’t Save Passwords!

So almost a year ago I got hacked, hacked real bad in fact and I literally (almost) pooped my pants – it was scary watching your whole online life disappearing before your eyes. Ironic in a way as I spend my time securing other people’s sites and lives – but often forget about my own. […]

A New Annoyance – Twitter Favourite Spam

I’ve noticed a lot of favourites on odd tweets lately, mostly my check-ins to beers from Untappd – then I started noticing some patterns. I get a whole flood of favourites on a single tweet, all of them have innocuous looking twitter handles (A name and a couple of letters, or two names) – mostly […]

Facebook Like Box Button Flyout Getting Cut Off – Woothemes Canvas

I’ve had this problem with a few themes, most recently with Woothemes Canvas and the social sharing plugin Digg Digg. Having used Digg Digg many times, and never having had this problem before I was a little confused. I tried dozens of tweaks in the css to try and fix it, tried all the different […]

Error Reading PID From File (0 Byte) With Monit After Service Crash

Sometimes services crash badly, in this case I was trying to stabilize an old server running nginx and PHP via Fast-cgi. It crashes quite often, so I set up monit on it – but I noticed monit has stopped doing it’s job due to the following batch of errors: Now the problem was, the PID […]

monit For Wowza on Ubuntu 12.04 LTS

So Wowza is a cool media streaming server, but sometimes it crashes..for no apparent reason – or perhaps sometimes you’ve just got the memory limit set too high for the machine and the process gets reaped. Either way it’s pretty important to keep it running, my favourite tool for this kind of job (process monitoring, […]

Intermittent MongoDB [conn5] assertion 16550 not authorized for query Error After Upgrade to 2.4

So I recently upgraded the main MongoDB replica set from 2.2.x to 2.4.x for performance and mostly for security after the recent major MongoDB vulnerability. Setting up the replica set in the first place wasn’t too troublesome, but maintaining has been a pain in the butt on and off, MongoDB does have some peculiarities. Once […]
