Enter the WasmForge: Compiling Sliver into WebAssembly

In our last post we used a Claude skill to systematically beat down VirusTotal detection rates on offensive security tools, with a brief mention of a new loader we’d been using to apply those techniques in bulk. This post is about that loader, which we call WasmForge. WasmForge is, from the user’s perspective, a build […]

Adversarial Oracles: LLM-Guided EDR Signature Reduction

In previous blog posts we’ve talked about getting nerd sniped. Today we’re going to talk about a kind of nerd sniping that any offensive security tool creator is familiar with; when your tool gets signatured. This normally kicks off a frustrating spiral of back and forth changes between the tool author and security vendors until […]

Your Login Page Is Lying: What AI Agents Find When They Read Your Frontend

A login page rendered semi-transparent, revealing JavaScript route definitions, API endpoint URLs, and a highlighted hardcoded secret behind it.

TL;DR: Single-page applications ship their entire frontend codebase to every visitor, including unauthenticated ones. Even a login page with no visible functionality delivers JavaScript bundles containing route definitions, API endpoint URLs, authentication logic, data models, and sometimes hardcoded secrets. As part of Guard’s continuous penetration testing, we use AI-assisted tooling to extract this information and […]

Which Came First: The System Prompt, or the RCE?

During a recent penetration test, we came across an AI-powered desktop application that acted as a bridge between Claude (Opus 4.5) and a third-party asset management platform. The idea is simple: instead of clicking through dashboards and making API calls, users just ask the agent to do it for them. “How many open tickets do […]

AI-Driven Offensive Security: The Current Landscape and What It Means for Defense

AI-driven offensive security cycle showing build, test, detect, and adapt phases around a cube with security symbols

The capabilities of modern AI models have advanced far beyond what most people in the security industry have fully internalized. AI-generated phishing, script writing, and basic offensive automation are getting plenty of attention, but what happens when you apply agentic AI to the full lifecycle of building, testing, and refining custom malware and command-and-control (C2) […]

Augustus v0.0.9: Multi-Turn Attacks for LLMs That Fight Back

Augustus v0.0.9 multi-turn LLM attacks

Single-turn jailbreaks are getting caught. Guardrails have matured. The easy wins — “ignore previous instructions,” base64-encoded payloads, DAN prompts — trigger refusals on most production models within milliseconds. But real attackers don’t give up after one message. They have conversations. Augustus v0.0.9 now ships with a unified engine for LLM multi-turn attacks, with four distinct […]

Mapping the Unknown: Introducing Pius for Organizational Asset Discovery

Pius open-source asset discovery tool terminal output showing CIDR ranges and domains discovered across multiple registries

Asset discovery is an essential part of Praetorian’s service delivery process. When we are engaged to carry out continuous external penetration testing, one key action is to build and maintain a thorough target asset inventory that goes beyond any lists or databases provided by the system owner. Pius is our open-source attack surface mapping tool […]

Beyond Prompt Injection: The Hidden AI Security Threats in Machine Learning Platforms

Beyond Prompt Injection

What’s the first thing you think of when you hear about AI attacks and vulnerabilities? If you’re like most people, your mind probably jumps to Large Language Model (LLM) vulnerabilities—system prompt disclosures, jailbreaks, or prompt injections that trick chatbots into revealing sensitive information or behaving in unintended ways. These risks have dominated headlines and security […]

Building Bridges, Breaking Pipelines: Introducing Trajan

TL;DR: Trajan is an open-source CI/CD security tool from Praetorian that unifies vulnerability detection and attack validation across GitHub Actions, GitLab CI, Azure DevOps, and Jenkins in a single cross-platform engine. It ships with 32 detection plugins and 24 attack plugins covering poisoned pipeline execution, secrets exposure, self-hosted runner risks, and AI/LLM pipeline vulnerabilities. It […]
