This is what I've been driving for the past year! It's an exciting time, with Rust making its way into one of the most critical pieces of software: the core crypto library used in Azure and Windows. With Rust, formal verification becomes easier, and so far, no blockers to Rust adoption.
Prompt Injection is a top risk for use of LLMs, where untrusted data can cause a system to misbehave or leak data. We're hard at work on deterministic solutions to prevent or bound the risk, and just published a paper on our innovative information flow control approach: arxiv.org/pdf/2505.23643
At some point I'll need to stop calling it Oakland
Learn about the risks of hallucination, jailbreaks and prompt injection and current mitigations in our ACM Queue paper:
Yes, they can hallucinate papers that don't exist, discuss results that seem to be imaginary, and can be confusing and inconsistent. But talking to tenured professors may still be helpful
📢Have experience jailbreaking LLMs?
Want to learn how an indirect / cross prompt injection attack works? Want to try something different to an advent of code?
Then, I have a challenge for you!
The LLMail-Inject competition (llmailinject.azurewebsites.net) starts at 11am UTC (that's in 5min!)
📢Internships in AI Security & Privacy
Our Azure Research team in Cambridge (UK) is looking for PhD or outstanding undergrad/MSc students for internships in 2025. Join us to work on defending against emerging security & privacy threats to AI systems.
