Constant-Time Data Processing At a Secret Offset, Privacy and QUIC

Introduction NCC Group Cryptography Services team assessed security aspects of several implementations of the QUIC protocol. During the course of their reviews, the team found a number of recurrent cryptography side channel findings of arguably negligible privacy risk to users, across these implementations. However, repetition in itself makes these findings somehow worth having a deeper … Continue reading Constant-Time Data Processing At a Secret Offset, Privacy and QUIC →

Writing FreeBSD Kernel Modules in Rust

At present all major operating system kernels are written in C/C++, languages which provide no or minimal assistance in avoiding common security problems. Modern languages such as Rust provide better security guarantees by default and prevent many of the common classes of memory safety security bugs. In this post we will take a brief look … Continue reading Writing FreeBSD Kernel Modules in Rust →

Implementing the Castryck-Decru SIDH Key Recovery Attack in SageMath

Introduction Last weekend (July 30th) a truly incredible piece of mathematical/cryptanalysis research was put onto eprint. Wouter Castryck and Thomas Decru of KU Leuven published a paper "An efficient key recovery attack on SIDH (preliminary version)" describing a new attack on the Supersingular Isogeny Diffie-Hellman (SIDH) protocol together with a corresponding proof-of-concept implementation. SIDH is … Continue reading Implementing the Castryck-Decru SIDH Key Recovery Attack in SageMath →

Tool Release – Ghostrings

Introduction Ghostrings is a collection of Ghidra scripts for recovering string definitions in Go binaries with P-Code analysis. A well-known issue with reverse engineering Go programs is that the lack of null terminators in Go strings makes recovering string definitions from compiled binaries difficult. Within a compiled Go program, many of the constant string values … Continue reading Tool Release – Ghostrings →

Mining data from Cobalt Strike beacons

Since we published about identifying Cobalt Strike Team Servers in the wild just over three years ago, we’ve collected over 128,000 beacons from over 24,000 active Team Servers. Today, RIFT is making this extensive beacon dataset publicly available in combination with the open-source release of dissect.cobaltstrike, our Python library for studying and parsing Cobalt Strike … Continue reading Mining data from Cobalt Strike beacons →
