Following the NCSC and CISA’s detailed joint advisory on the highly sophisticated ‘Snake’ cyber espionage tool, JUMPSEC threat intelligence analysts have provided a condensed blueprint for organisations to start proactively hunting for Snake within their network, contextualising key Indicators of Compromise (IoC), and providing additional methods to validate the effectiveness of Snake detections. Snake’s capabilities The implant dubbed ‘Snake’ has been attributed to Centre 16 of Russia’s state...
The JUMPSEC Lab is a place where the the technical team get creative and showcase their latest security research, publications, interesting news and general thoughts! We love what we do and are passionate about security, with some great upcoming projects planned, bookmark our site and stick around to see what we are working on.
I recently worked on a project focused on log anomaly detection using manageable machine learning pipelines. The pipelines mainly include data collection --- feature extraction --- feature engineering --- detection/prediction --- updating (maintenance). It’s important to have a solid UI to manage the pipelines so I can easily review the chain of pipelines. After much research, I found many engineers recommended Airflow. In airflow, the core concept is the Directed Acyclic Graph...
JUMPSEC investigators recently observed an adversary weaponising PowerShell Jobs to schedule their attack whilst responding to an incident. We discuss what PowerShell Jobs are, how they can be leveraged for malicious purposes, and how defenders can protect, detect, and respond to neutralise the threat.
The Windows registry is a vast and complex topic and cannot be understood and defended in one article. One particular area of interest from a security perspective is registry run keys. In this article, we discuss who uses them, how to uncover abuse, and how to eradicate evil from them.
By Dray Agha The infosec community has been busy dissecting the PrintNightmare exploit. There are now variations of the exploit that can have various impacts on a target machine. When we at JUMPSEC saw that Lares had captured some network traffic of the PrintNightmare exploit in action, I wondered if there was an opportunity to gather network-level IoCs and processes that could offer defenders unique but consistent methods of detection across...
SpecterOps recently released an offensive security research paper that details techniques enabling an adversary to abuse insecure functionality in Active Directory Certificate Service. SpecterOps reports that abusing the legitimate functionality of Active Directory Certificate Service will allow an adversary to forge the elements of a certificate to authenticate as any user or administrator in Active Directory. JUMPSEC has highlighted numerous changes that can be made to Active Directory...
Recently we posted a bunch of advisories relating to Ivanti Unified Endpoint Manager, a couple of which are for vulnerabilities which can be used to achieve local privilege escalation. We will give a brief explanation of the vulnerabilities and an example of Sysmon configuration rules to log exploitation attempts, along with the rationale behind them so you can adapt them to your existing configuration if needed.
Post exploitation is large part of a red team engagement. While many organisations begin to mature and start to deploy a range of sophisticated Endpoint Detection & Response solutions (EDR) onto their networks, it requires us, as attackers to also mature. We need to upgrade our arsenal to give us the capabilities to successfully operate on their networks. That is why today, I am releasing shad0w.
shad0w is a post exploitation framework which is designed to operate covertly on such networks, providing the operator with much greater control over their engagements. Over future blog posts I will go into greater detail on the intricacies of how shad0w works. This blog post will, therefore, serve as an introduction into the usage and features that shad0w has to offer.
