How Not to Detect Prompt Injections with an LLM LLM-integrated applications and agents are vulnerable to prompt injection attacks, in which adversaries embed malicious instructions within seemingly benign user inputs to manipulate the LLM's intende...

In this work, we formally characterize the KAD scheme and uncover a structural vulnerability in its design that invalidates some core security principles.
We design a methodical adaptive attack, DataFlip, to exploit this fundamental weakness. Read about the details arxiv.org/abs/2507.05630

Recent defenses based on known-answer detection (KAD) have achieved near-perfect performance by using an LLM to classify inputs as clean or contaminated.

LLM-integrated applications and agents are vulnerable to prompt injection attacks, in which adversaries embed malicious instructions within seemingly benign user inputs to manipulate the LLM’s intended behavior.

Translating Legacy Code for a Safer Future: DARPA Backs Effort to Convert C to Rust The C programming language—powering everything from operating systems to aircraft control software—has long been a cornerstone of modern computing. But its flexibility comes at a cost: memory safety i...

Recently, we received a DARPA grant on the problem of LLM-assisted translation of C to Rust. The team consists of amazing set of PIs from UW, Berkeley, UIUC, and Edinburgh. Really excited about what we can do.

SAGAI'25 will investigate the safety, security, and privacy of GenAI agents from a system design perspective. We are experimenting with a new "Dagstuhl" like seminar with invited speakers and discussion. Really excited about this workshop at IEEE Security and Privacy Symposium.

These kind of comparisons are not very useful. Everyone should be charting their own course!

Lorenzo graduated from my group and did some cool work on system and network security during his Ph.D. Congrats, Lorenzo!

Proud of you.

* removes reliance on public datasets, which was assumed in many existing integrity checks.

* enables advanced integrity checks, such as cross-client validation accuracy, which were impossible in prior secure FL approaches. We show these checks are effective under model poisoning attacks and client data distribution shifts.

Why SLVR? Building on secure Multi-party Computation (MPC), SLVR offers a fresh perspective on combining privacy and robustness in federated learning:
* leverages private client data while preserving the privacy guarantee of secure aggregation.

Have you ever wondered: In federated learning, what if we could leverage clients' private data without compromising privacy—what more could we achieve?

🚀 We're excited to introduce SLVR (Securely Leveraging Client Validation for Robust Federated Learning).
