BCP, as easy as ABC?

by Matt Lawrence | Dec 2, 2024 | Incident Response

A Business Continuity Plan (BCP) is a strategic playbook created to help an organisation maintain or quickly resume business functions in the face of disruption. (Pratt, Tittel, Lindros, 2023) Be honest now. Who really has a truly effective Business Continuity Plan in 2024? Not the compliance-driven plan that has not been reviewed or tested properly for years. Or the “oh no, this supplier questionnaire is asking for a BCP… quick, write one” plan that won’t be much help in reality. Who has an effective plan that will be genuinely useful to their organisation in a time of crisis? Not many organisations do and it’s understandable. We are not aiming to criticise anybody's hard work here. We get it. To put it mildly, the sheer amount of items on any organisation's to-do list combined with budget and resource constraints often lead to things like Business Continuity Planning being...

Active Cyber Defence – Taking back control

by Umair Qamar | Oct 15, 2024 | Detection, Incident Response

Every good cybersecurity article needs a Sun Tzu quote, here is one lesser known quote from Sun Tzu to start us off. What Happened? Recently, JUMPSEC’s Detection and Response Team (DART) caught a Red Team inside one of our MxDR clients' networks using a honeypot server. The honeypot server was set up using Thinkst Applied Research’s project called OpenCanary. This open-source project...

NTLM Relaying – Making the Old New Again

by David Kennedy | Sep 17, 2024 | Red Teaming

I am old enough to remember that it was not always possible to get domain admin within the first hour of a test via Active Directory Certificate Services (ADCS) misconfigurations or over permissioned SCCM NAA accounts. At present we are spoilt for choice in regards to privilege escalation vectors within the on-premise AD environment's, but I wanted to take a look at some of the other...

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...

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...

How to Handle Development Projects in a Pentest Company

by Bjoern Schwabe | Aug 6, 2024 | Jumpsec, Research

If you are a pentester you probably never really think about programming. Instead you are testing what others have developed. However, every now and then a quick python or bash script is needed to exploit some stuff you have found, or automate a certain process you are using. Things become interesting when you are in a penetration testing company that has many strong penetration testers and...

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...
