We wanted to build a mechanism to capture all the passwords used (successful or not) against RDP to ascertain potential sources of credential theft and if they are organisation specific. This post provides the background on an approach and the steps to build such a system.
One true constant (until someone schools me) is that threat actors need executable memory of some kind to operate from for their endpoint implant even if fleeting. Given this we've released an open source Microsoft Windows Service that aims to facilitate detection of anomalous executable memory
CVE-2020-5902 was disclosed on July 1st, 2020 by F5 Networks in K52145254 as a CVSS 10.0 remote code execution vulnerability in the Big-IP administrative interface. This blog looks at the root causes of both the exploit paths discovered which boil down to subtle configuration issues and differences in behavior between Apache httpd and Apache Tomcat when dealing with an uncommon URI element called matrix (or path) parameters.
The Thinkst Canary is best described as a digital tripwire for physical and virtual environments. It sits there waiting for a threat actor to tip you off they are mooching around your environment. What is less appreciated however is it is extensible with custom user modules. This post is the first in a series detailing our experiments in extending the product.
tl;dr Today we've released a whitepaper on the key techniques that continue to enable us to breach the largest and most sophisticated organisations on the planet. Organisations that prioritize these areas, and the mitigations we outline, will thwart attacks while making threat actors work harder and ultimately fail more often. Objective The purpose of this … Continue reading Paper: Thematic for Success in Real-World Offensive Cyber Operations – How to make threat actors work harder and fail more often
Earlier last month saw the publication an IETF draft NCC Group co-wrote with the UK's National Cyber Security Center titled 'Indicators of Compromise (IoCs) and Their Role in Attack Defence'

Because they wanted to measure what the impact of NotPetya would have been. Below, you’ll find part one of the story… When you dodge a … Continue reading EternalGlue part one: Rebuilding NotPetya to assess real-world resilience
