This was also presented at BSides Singapore 2020. The slides are here and YouTube link is here. The origins of the Shadowbunny A few years ago, around 2016, I went on a relaxing two weeklong vacation. It was great to disconnect from work.

This year one of my goals was to learn about machine learning and artificial intelligence. I wrote about my journey before - including what classes I took and books I read, the models and systems I built and operationalized, threat modeling it to learn about practical attacks and defenses. My goal is to be knowledge enough in the AI/ML space enough to be able to help bridge the gap between research and operational red teaming - by doing practical things with life systems.

My heritage is Sri Lankan. But, at the age of 15 I moved to France as a refugee, fleeing a civil war. Starting a new life from scratch in France, without speaking French, was certainly an interesting journey. But I was lucky enough to have support from my parents. They lived by the mantra of "when there's a will, there's a way". And that helped get me into the French education system, where I completed high school and University, before moving to the UK to start my professional career in IT.

Overview: How Husky AI was built, threat modeled and operationalized Attacks: The attacks I want to investigate, learn about, and try out Mitigations: Ways to prevent and detect the backdooring threat During threat modeling we identified that an adversary might tamper with model files. From a technical point of view this means an adversary gained access to the model file used in production and is able overwrite it.

Data privacy and security experts tell us that applying the “need to know” principle enhances privacy and security, because it reduces the amount of information potentially disclosed to a service provider — or to other parties — to the minimum the service provider requires to perform a service.  This principle is at the heart of […]
