PowerShell Jobs

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.

Introduction I recently researched modern algorithms used by keyfobs to open cars. Since most of the blogs online talking about the topic are unfortunately quite old and in general and do not precisely describe the exact path followed in detail, nor the code used. I thought that talking about my experience could be interesting and inspiring for other researchers. I won’t go in depth on certain...

PRINTNIGHTMARE NETWORK ANALYSIS

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...

Securing against new offensive techniques abusing active directory certificate service

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...

Overcoming Issues Using Custom Python Scripts with Burp Suite Professional

Summary / TL:DR I recently encountered some issues when using Burp Suite Professional which led me to playing around with the Python Scripter extension. The extension allows running custom Python scripts on every request/response processed by Burp, including those generated by functionality such as Burp's active scanner. This has a number of potential use cases, but I found it particularly...

Detecting known DLL hijacking and named pipe token impersonation attacks with Sysmon

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.
