Oh. Good. That won’t be a problem.

We've released some preliminary research today demonstrating fine tuning attacks which can bypass the safety mechanism of DeepSeek-R1. These simple attacks show that DeepSeek's safety can be easily removed to provide harmful content, and potentially to a worse extent to non-reasoning LLMs.

First day of the first full week of three of teaching ICS security!

12 Allen Bradley teaching boxes delivered today ready for the first week of our cyber MSc ICS security unit next week. With the 6 we already have and 4 more being built we will have 22 Allen Bradley boxes to go with our 25 Siemens boxes, and will soon expand to 20 IoT/IIoT boards to go with them!

What in the actual hell?

Excited! I've been wanting to see Del Amitri for years. My dad is a long time fan and also his first time seeing them

First time getting one of the UK emergency mobile alerts that isn't a test!

Do you or your company require Industrial Control Systems security training, up-skilling or re-skilling? We have example courses on our website, but will work with you to create a training programme that best suits your needs - hacktonics.io/courses

AI chatbot startup WotNot leaks 346,000 files, including passports and medical records https://www.bitdefender.com/en-us/blog/hotforsecurity/ai-chatbot-startup-wotnot-leaks-346-000-files-including-passports-and-medical-records

Oh no they are here!

For some reason I've been suspended on Twitter. No idea why as I haven't posted in a week!

Today is water plant cleaning day! It was due a full water change and clean of the tanks. I love doing OT security research but this is definitely the less glamorous side 😅

Weekly summary is out... ctoatncsc.substack.com/p/cto-at-ncs...

That awkward moment when you find a paper has fully plagiarised one of your own published works, and you only discover it by the plagiarisers making the fatal mistake of citing the paper they copied!

Prototype of a new little demo I'm working on. Process manipulation of a running ICS process from an android phone on the wifi. Simple app for identifying IPs, Siemens devices then using library to interact with device and cause boxes to be incorrectly sort! Now to apply it to the water plant...

Twitter is becoming unusable, so let's give this one another shot!

Let's see how this one goes then!
