Hey 👋, I'm Liam

I'm currently a Principal Security Researcher at Microsoft Security Research (MSecR), where I work on R&D related to Threat Intelligence and Detection for Microsoft Defender for Endpoint (EDR) and Windows Defender Antivirus.

I write a lot of Python 🐍 with Pandas 🐼 in Jupyter Notebooks 🚀 to mine interesting security events from trillions of daily signals held in Kusto ☁️🌊.

Here are some recent spare-time projects:

• I've recently completed a Postgraduate Diploma in Mathematics on the way to an MSc.
• I'm currently (2022-23) studying for a Graduate Certificate in Theoretical Statistics and Probability.
• fractal-cuda - render deep Mandebrot sets on the GPU with CUDA.
• 8bitcpu - my Ben Eater 8-bit breadboard computer with assembler and emulator. Requires at28c256 Arduino EEPROM programmer.

I spent 15 years working on Vulnerability Research and Windows Internals, and here are some ancient obsolete Windows security tools:

• scant and scamp
• lsppyfilter
