NTLM Relaying – Making the Old New Again

by David Kennedy | Sep 17, 2024 | Red Teaming

I’m old enough to remember that it wasn't possible to get ‘Domain Admin’ within the first hour of a test via Active Directory Certificate Services misconfigurations or over permissioned SCCM NAA accounts. As an adversary simulation team we are now spoilt for choice in regards privilege escalation within the on-prem environment. With that in mind I wanted to take a look at some of the other misconfigurations that have proved to be fruitful before the advent of ADCS and SCCM, such as: Lack of...

Adversary at the Door – Initial Access and what’s currently on the menu

by Patryk Zajdel | Aug 20, 2024 | Initial Access, Red Teaming

Based on the data from the Cyber Security Breaches Survey 2024, phishing with malicious links or malware remains the most common initial access vector, followed by impersonation. The challenge with impersonation attacks is that current technology often struggles to accurately determine the purpose of a website. Although checks on domain maturity, reputation, categorization, and certificates are performed, a skilled adversary can still create sophisticated phishing infrastructure that hosts...

SSH Tunnelling to Punch Through Corporate Firewalls – Updated take on one of the oldest LOLBINs

by Sunny Chau | Aug 13, 2024 | Adversary Infrastructure, Initial Access, Red Teaming

In my formative days of learning network hacking, SSH tunnelling was amongst the first tunnelling techniques that I learnt. I still remember trying to repeatedly decode my notes and diagrams on the rather cumbersome syntax of single port forwarding with the -L and -R flags, which at the time was taught as “the way to do it”. If your foothold is (luckily) a Linux server, then you’re blessed with the -D flag to spin up a SOCKS proxy on the foothold itself to access the network via proxychains....

How Cloud Migration is Affecting AppSec – A Red Teamer’s Perspective

by Max Corbridge | Jul 4, 2024 | Application Security, Azure Cloud, Azure DevOps, Cloud Red Team, Initial Access, Jumpsec, Red Teaming

Introduction I’ve recently spoken at several conferences about the changes that are underway within red teaming as a result of cloud migration. My team and I have been delivering majority cloud red team work over the last year and the differences are becoming more apparent by the day. One point I’ve mentioned as ‘controversial’ at several of these events is that cloud migration has actually made AppSec more important than ever. I went some way to trying to explain why I think this is during my...

by Francesco Iulio | May 31, 2024 | Initial Access, Red Teaming

TL;DR This blog post introduces Web Assembly (WASM) as a powerful alternative to traditional web technologies, highlighting its appeal to cybersecurity professionals for evading security measures for initial access. WASM has been observed being leveraged in the wild as a new payload delivery avenue which can land payloads in a hardened email inbox or instant messaging chats. A new tool, W.A.L.K. (Web Assembly Lure Krafter), is released alongside this blogpost to automate the generation of...
