2018-05-13 -  A while ago I wrote a post about using Python to parse tcpdump output for domains and URLs. Recently, I started to wonder if I could take that a step further. What if the DNS requests I saw could be checked against a blacklist in real time? And what if...

2018-05-07 -  Welcome to what might be a new regular post series, which I’m going to nickname “Stuff I only posted to Instagram and haven’t had a chance to write about yet”. Basically, I’m making an effort to make more of my weekends, and if I start writing about it I’m probably...

2018-04-29 -  The life of a SOC analyst – as is the case with many other jobs – can involve a lot of repetitive tasks, including the process of writing tens of similar emails each day. But what if this could be automated, saving time and reducing the potential for error? The...

2018-04-08 -  Part of my time at the SANS Cyber Retraining Academy covered the incident response methodology and how to identify what’s wrong and how to fix it. But theory is quite different to the real thing, so I thought it would be useful to make a cheat sheet with a few...

2018-03-17 -  I’ve just arrived back in the UK after spending nearly two weeks travelling across Japan, visiting Tokyo, Nagoya, Osaka and Kyoto. Before I get back to work and the memories start to fade, I wanted to put pen to paper and share some experiences, thoughts, and photos. I have a...

2018-02-23 -  I have a confession to make: I’ve never liked the way the Apple Watch looks. I’ve owned a range of Apple products over the last decade and I’ve always thought they were beautiful and well-polished, but wearing a big silver box on my wrist has never appealed to me. Unfortunately,...

2018-01-20 -  It’s almost a year to the day that I left my journalism job and started at the SANS Cyber Retraining Academy, and I’ve written a lot of blog posts about how much I enjoyed the experience and how valuable and life-changing it was. But now I’ve been in the industry...

2017-12-28 -  It’s the Christmas break, and in between family gatherings and travelling up and down the country I’ve finally found time to get stuck into a few good games and books. What I’ll be playing in 2018 My new work commitments mean I don’t get as much chance to play games...

2017-12-18 -  There’s a lot more to most websites than meets the eye these days, and I thought an interesting Python project to take on at the start of my Christmas break would be to uncover the extra requests hidden below the surface with some help from tcpdump. The challenge? Tcpdump’s output...

2017-11-30 -  After I managed to pull data from Twitter’s API using Python, I got thinking about what my next step would be. Then it hit me – I could draw data from external sources and find a nice extension to visualise it in some pretty graphs. Plotly is that extension. My...
