After nearly four years into my role, I am stepping down as NCC Group’s SVP Global Head of Research. In part just for myself, to reflect on a whirlwind few years, and in part as a thank you and celebration of all of the incredible researchers with whom I have had the privilege of working, […]

New Microcorruption challenges created by Nick Galloway and Davee Morgan Today we are releasing several new challenges for the embedded security CTF, Microcorruption. These challenges highlight types of vulnerabilities that NCC Group’s Hardware and Embedded Systems practice have discovered in real products. The new challenges provide a simple interface to explore these vulnerabilities without having […]

In June 2022, IOV Labs engaged NCC Group to perform a review of powHSM. Per the project documentation: “Its main role is to safekeep and prevent the unauthorized usage of each of the powPeg’s members’ private keys. powHSM is implemented as a pair of applications for the Ledger Nano S, namely a UI and a Signer, […]

Six years ago, NCC Group researchers Tim Newsham and Jesse Hertz released TriforceAFL – an extension of the American Fuzzy Lop (AFL) fuzzer which supports full-system fuzzing using QEMU – but unfortunately the associated whitepaper for this work was never published. Today, we’re releasing it for the curious reader and historical archives alike. While fuzzing […]

During the summer of 2022, Penumbra Labs, Inc. engaged NCC Group to conduct a cryptographic security assessment of two items: (i) the specification and two implementations of the decaf377 group, and (ii) a methodology and implementation of parameter generation for the Poseidon hash function. Decaf377 is a prime-order group obtained by applying the Decaf construction […]

This paper collects a set of notes and research projects conducted by NCC Group on the topic of the security of Machine Learning (ML) systems. The objective is to provide some industry perspective to the academic community, while collating helpful references for security practitioners, to enable more effective security auditing and security-focused code review of ML systems. Details of specific practical attacks and common security problems are described. Some general background information on the broader subject of ML is also included, mostly for context, to ensure that explanations of attack scenarios are clear, and some notes on frameworks and development processes are provided.
