If your into OT security, we have just released LINICS, our new free ICS testing distribution. This includes a number of tools, including some we have built ourselves!
Please do get in touch if you have any questions, or would like to contribute!

“Before I was fired tonight, I was in charge of information security for VA.gov, which has millions of users per month and stores and processes huge amounts of veterans' personal information. I've been told by people I've worked with that I'm the best at what I do of anyone they've ever worked with. Now there will be _no one_ in charge of information security for VA.gov. Does this seem like improving government efficiency? #politics #USPol #DOGE #USDS #VA #infosec”

Oh. Good. That won’t be a problem.

New AI app DeepSeek poses ‘severe’ safety risk, according to new research A fresh University of Bristol study has uncovered significant safety risks associated with new ChatGPT rival DeepSeek.

We believe this is the first practical demonstration of fine tuning attacks on a chain-of-thought (CoT) LLM.

New AI app DeepSeek poses ‘severe’ safety risk, according to new research A fresh University of Bristol study has uncovered significant safety risks associated with new ChatGPT rival DeepSeek.

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?

No they were excellent!

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

Not too bad here so far. We're right on the edge of the red area so hopefully should avoid the worst of it!

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

Doesn't start until today!

Slowly getting there, but now the "good" knee keeps locking so have an MRI on that next week!

I'm hoping it recovers enough, so there is potential for doing something like it down the line...

I can just about do 20-30 mins of low resistance on the bike now though which is something!

I had a plan after seeing the Bristol half marathon and 10k in may this year to train up and take part in 2025 for charity, as the cardio had been going well in the gym. Dislocated my knee a month later and the other has been damaged by compensating. My running career was over before it started 🤣

I can't see my past tweets properly until the hopefully unsuspend my account, but for me it was the posts around the cow collar work and the pun storm from the vx-underground and anonymous posts tagging me.

Yeah I only watched it recently. I thought it was a new show then discovered it had been going 2 years with 4 seasons! Apple are awful at advertising their shows. Especially of that quality!

Must have been 😂

Oh no they are here!

More just an annoyance as I still follow people on there who haven't moved over to here. Seems like it may be a bug though as I can see anything on there

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 😅

Is that cafe republic?

Yes this is a pain - even the external magic keyboard seems to just hold onto finger marks. The macbook screens also seem to just absorb fingerprints into the glass!

Bristol is just very wet 😢

An edit button would be nice (and without a paywall)

And the MFA can just be SMS. For most people that works with their threat model.
