1. Introduction

Traditional LLM red teaming focuses primarily on basic jailbreak and prompt injection attacks. These techniques can only detect vulnerabilities at the surface level. They cannot identify the complexity of real-world adversarial behavior. Static testing fails to simulate threats and the system’s reaction under dynamic attack conditions. This creates the need for testing frameworks that extend single-turn prompts.

This gap is fulfilled by RedTeamLLM, which allows the simulation of goal-oriented exploitation through autonomous agents equipped with reasoning, planning, and memory. Unlike static probing,it uncovers vulnerabilities dynamically through adversarial simulations involving tool interaction, roleplay, and plan correction. DeepTeam enhances this further and defines threat scenarios by introducing a programmatic interface and reusing previous attack simulations for iterative testing.

3. Strategic Memory: How RedTeamLLM Learns and Improves Over Time

RedTeamLLM uses memory management at the high level, during which the agent decides on the execution plan. Using task description embedding, all traces of the execution process are saved in a tree format after each execution process.

The planner queries the saved nodes during decomposition, accessing their sub-tasks, detailed execution, and success/failure reasons. In this way, the agent is improved with time by narrowing possibilities to the right path, especially when the task is re-executed. This also enhances the RedTeam LLM and increases the chances of completing the task over multiple rounds of execution.

The execution of RedTeamLLM involves four distinct stages:

4: Case Study: Roleplay-Based Red Teaming of Claude 4 Opus Using DeepTeam

To evaluate Claude 4 Opus’s robustness against adversarial prompts using DeepTeam, targeting three major vulnerabilities:

.

We used two approaches. In the first approach, we tried prompt injection, but it failed. In the second approach, we tried role-playing, which was successful.

5. Inside DeepTeam: A Tactical Framework for Testing AI Resilience

DeepTeam simulates smart social engineering to test how AIs react under pressure by blending bias traps and role-play personas, revealing hidden cracks in model defenses

Multi-turn attack: Uncover LLM Bias, Toxicity, Vulnerabilities Fast

This code sets up an automated red-teaming framework to test LLM for vulnerabilities, e.g, race, gender, toxicity (e.g, insult). For this, it uses a multi-turn attack called Linear Jailbreaking, where the attacker tries to bypass safeguards over up to 15 conversation turns

from deepteam import red_team

from deepteam.vulnerabilities import (

    Bias, Toxicity, Competition, …

)

from deepteam.attacks.multi_turn import LinearJailbreaking

async def model_callback(input: str) -> str:

    # Replace with your LLM application

    return “Sorry, I can’t do that.”

bias = Bias(types=[“race”, “gender”, …])

toxicity = Toxicity(types=[“insults”])

linear_jailbreaking_attack = LinearJailbreaking(max_turns=15)

red_team(

    model_callback=model_callback,

    vulnerabilities=[

        bias, toxicity, …

    ],

    attacks=[linear_jailbreaking_attack]

)

 

DeepTeam is a modular red teaming framework that conducts security assessments. Attack modules, such as roleplay and prompt injection, assess system vulnerabilities by simulating attack vectors. Vulnerability targets focus on toxicity, bias, and unauthorized access to address critical areas that can compromise the security and integrity of the system.
