My book on #AdversarialAI is now available on Amazon. Written for #cybersecurity professionals and any builder or defender with in-depth hands-on walkthrough of #AI threats and how to safeguard against them using @NIST , @MITREcorp and @owasp guidance amzn.eu/d/07EyqxJx
🚨 The UK is demanding backdoor access to Apple’s encrypted iCloud data, setting a dangerous global precedent. If one government weakens encryption, others will follow.

Writing a book on a complex subject like AI security is hard work. But it becomes easier with a welcoming place to write and the support of great people. @NeroUK your team at Bromley, High Street are amazing,.Thank you.

Well actually a lot of credit needs to go to a young Rebecca Thomson who first broke the story in @ComputerWeekly in what must have been one of her very first major assignments.

I've spent several years studying machine learning security with the goal of making ML reliable before it is used in more and more important contexts. Unfortunately, ML capabilities and adoption are growing much faster than ML robustness. safe.ai/statement-on-ai-risk
Amazing technology can be used for both good and evil. We should resist the temptation to halt progress. But we should also go beyond the current "oh wow"s and develop appropriate safeguards and defenses businessinsider.com/gpt4-ope… #ai #security #trustworthyai #ChatGPT #openai
We should not halt the bold march of progress but we must not ignore the warnings of wise people either. Regulating #AI and defending it from #adversarial attacks is the next frontier theguardian.com/technology/2…

Josephine sets a great example to us all by postponing her birthday party until we have sent coronavirus packing.
Together we can beat this. In the meantime let's all wish her happy birthday (twice) whilst washing our hands. #BeLikeJosephine #StayHomeSaveLives
ALT Happy birthday! I am glad to hear you are staying at home, though I am sorry to hear about your party! We have all got to do our bit to protect the NHS and save lives, and that is exactly what you are doing, so well done! You are setting a great example. If we can work together we can send coronavirus packing. And once we have done that, you can DEFINITELY have a party with your friends!

The Microsoft <> OpenAI news is much bigger than we first thought:
- $10 billion investment in the works, with Microsoft getting 75% of revenue until it recoups all $10b
- GPT in Office, not just Bing
