There’s Always Something: Secrets Detection at Engagement Scale with Titus
TL;DR: Titus is an open source secret scanner from Praetorian that detects and validates leaked credentials across source code, binary files, and HTTP traffic. It ships with 450+ detection rules and runs as a CLI, Go library, Burp Suite extension, or Chrome browser extension — putting secrets detection everywhere you already work during engagements. Say you find […]
Ghost Calls: Abusing Web Conferencing for Covert Command & Control (Part 2 of 2)
In part one, we discussed the architecture of web conferencing applications, with a specific focus on Zoom’s architecture to support web conferencing at a massive global scale. Part two will discuss the approach we developed to support tunneling traffic through Zoom and Microsoft Teams using the TURN protocol. Let’s start with a quick recap of […]
Hunting for Secrets in Plain Sight: Leveraging Internal Logging and Monitoring Services
In penetration testing and red teaming, success often lies in uncovering hidden paths of least resistance. While sophisticated exploits and zero-days frequently capture headlines, highly effective attack opportunities often hide in plain sight – like within internal logging and monitoring platforms. At Praetorian, we’ve observed first-hand the value of targeting internal logging and monitoring platforms […]
Agent of Chaos: Hijacking NodeJS’s Jenkins Agents
Relationships are complicated. When multiple DevOps platforms work together to execute pipelines for a single GitHub repository, it begs the question: Do these platforms get along? Node.js, the most popular JavaScript runtime in the world, uses a set of triplets to execute its CI/CD pipelines: a GitHub App, GitHub Actions workflows, and Jenkins pipelines. Like […]
ELFDICOM: PoC Malware Polyglot Exploiting Linux-Based Medical Devices
A high severity vulnerability in DICOM, the healthcare industry’s standard file protocol for medical imaging, has remained exploitable years after its initial disclosure. The flaw enables attackers to embed malicious code within legitimate medical image files. While previous research demonstrated this vulnerability’s impact on Windows-based medical systems, Praetorian’s new proof of concept, ELFDICOM, extends the […]
An Improved Detection Signature for the Kubernetes IngressNightmare Vulnerability
Wiz recently published a detailed analysis of a critical vulnerability in the NGINX Ingress admission controller—what they’ve dubbed IngressNightmare (CVE-2025-1097, CVE-2025-1098, CVE-2025-1974, CVE-2025-24514). The vulnerability stems from insufficient input validation during configuration file processing, allowing an attacker to inject arbitrary code into the NGINX process. Wiz’s writeup is excellent and covers the technical nuances thoroughly, […]
CodeQLEAKED – Public Secrets Exposure Leads to Supply Chain Attack on GitHub CodeQL
A potential supply chain attack on GitHub CodeQL started simply: a publicly exposed secret, valid for 1.022 seconds at a time. In that second, an attacker could take a series of steps that would allow them to execute code within a GitHub Actions workflow in most repositories using CodeQL, GitHub’s code analysis engine trusted by […]
Analyzing the SonicWall Custom Grub LUKS Encryption Modifications
Overview Recently, we decided to perform some reverse engineering of the SonicWall NSv appliance to identify any potential remote code execution vulnerabilities within the appliance. During our initial analysis of a virtual machine image for the application, we discovered a customized LUKS encryption mechanism meant to hinder reverse engineering of the application. We were able […]
