ai-kill-chain

Extended Cyber Kill Chain for AI-Era Threats An update to the Lockheed Martin Cyber Kill Chain for defenders working against LLM and agentic AI attacks. Adds a pre-attack stage for model supply chain compromise. Adds AI-specific sub-techniques to each of the original seven stages. Splits the...

authproof-sdk

AuthProof SDK AuthProof is an audit and attribution layer for AI agents. It lets you prove what a user authorized before the agent acted, and it records what the agent actually did against that authorization. The mechanism is simple. The user signs a delegation receipt with their own private key...

Vigolium - High-fidelity vulnerability scanner fusing agentic AI with native speed, modularity, and precision Vigolium provides two complementary scanning modes: Native Scan vigolium scan: Fast, powerful, and flexible. Deterministic, multi-phase scanning with 317 modules across content discovery,...

Persona Guardrail: A Production-Grade Defense Framework for Agentic Systems

Large language model-based agents are increasingly deployed to perform domain-specific tasks by interacting with enterprise knowledge, tools, and external services. Existing runtime guardrails primarily target prompt injection and other attack-specific behaviors under a black-box threat model, bu...

Attack Success Rate Is Not a Number: On Measurement Validity in Agentic AI Security Evaluation

Attack success rate ASR is the headline metric in nearly every published evaluation of attacks on, and defenses for, LLM agents. We argue that ASR as currently used is not a single quantity but a family of metrics parameterized by six design choices that papers seldom specify and never hold...

Trustworthy Agentic AI: A Comprehensive Cybersecurity and Systems Survey on Threat Landscapes, Defense Architectures, and Open Challenges

The transition from passive foundation models to autonomous, goal-directed agentic AI systems has introduced unprecedented capabilities by coupling recursive cognitive reasoning loops, persistent memory architectures, live tool execution planes, and multi-agent collaboration topologies. However,...

mulot -4285F4?logo=googlechrome&logoColor=white Agentic AI web pentester that drives a browser. An open-weights LLM GLM-5.2, Gemma or Qwen drives a real headless Chromium through a Burp-style toolkit and works a target the way a human pentester would. No frontier model, no agent running inside a...

Black-Box Red Teaming of Agentic AI: A Taxonomy-Driven Framework for Automated Risk Discovery

Agentic systems are rapidly moving to production, where they read untrusted inputs, call tools with real permissions, and act autonomously, expanding the security surface beyond chat-only models. Yet standard evaluations remain single-turn and fail to capture multi-step agent vulnerabilities. We...

MemSentry: A Framework for Detecting Persistent Memory Poisoning in Agentic AI

Agentic AI systems with persistent memory introduce a distinct attack surface known as memory poisoning, in which adversarially crafted content is stored in long-term memory and subsequently influences future agent behavior. Such attacks can suppress security alerts, facilitate privilege...

Skynet: Workflow-Level Anomaly Detection for Agentic AI Via Semantic and Structural Modeling

Agentic AI systems execute complex tasks through long-horizon workflows of planning, tool use, and multi-agent coordination. Task failures in these systems often originate from a single step, such as an injected prompt or a flawed plan, and are then amplified through downstream dependencies as th...

Dissecting Attacks Is Only Valuable If It Informs Controls: What the Unit 42 agentic AI investigation should change in your control set, stage by stage.

The volume of published incident research involving agentic AI is increasing, and the analysis that follows each report tends to concentrate on the same attribute: speed. The recent investigation from Unit 42, the threat intelligence and incident response group at Palo Alto Networks, is a...
