The Genesis of Morris II: A New Cyber Threat

At the heart of this cybersecurity conundrum lies Morris II, a sophisticated GenAI worm named after the infamous Morris Worm, reflecting its lineage and the evolution of digital threats. Morris II specifically targets these interconnected GenAI ecosystems, exploiting the seamless communication between GenAI-powered agents to replicate, propagate, and execute malicious activities. Unlike traditional malware, Morris II uses adversarial self-replicating prompts that deceive GenAI models into reproducing these prompts as outputs, enabling the worm to self-replicate and spread across the network without detection.

Targeted Ecosystems and Malicious Mechanisms

Morris II’s primary battlefield is the GenAI ecosystem — an interconnected network of agents relying on GenAI services for input processing. These ecosystems, pivotal in the operation of modern-day applications, from email assistants to virtual helpers, become vulnerable through their reliance on remote or local GenAI models. Morris II leverages this dependency to execute three critical actions: replication, propagation, and performing malicious activities. It employs ingenious methods such as RAG-based propagation and application-flow-steering to ensure its spread and persistence within these ecosystems.

The Zero-click Menace and Adversarial Self-Replicating Prompts

One of the most alarming aspects of Morris II is its zero-click nature, enabling the worm to execute payloads automatically upon reaching a new host, without necessitating any action from the user. This capability not only underscores the sophisticated nature of Morris II but also exemplifies the significant risks associated with automatically processed inputs in GenAI-powered applications.

This worm intricately weaves through the fabric of GenAI ecosystems, exploiting the advanced AI capabilities of agents to process inputs and make decisions, often with little to no human intervention. Morris II specifically preys on applications leveraging RAG to enhance query responses with contextually relevant information from an active database, a feature that’s become integral to applications such as email assistants designed for auto-response functionalities.

Targeting the Heart of GenAI-powered Agents

Morris II zeroes in on GenAI-powered email assistants, exploiting their reliance on RAG to generate responses based on a continuously updated database of user correspondences. By injecting an adversarial self-replicating prompt into an email, Morris II ensures its propagation across the GenAI ecosystem. This not only contaminates the RAG database with the malicious prompt but also ensures that future correspondences inadvertently aid in the worm’s propagation by considering the infected email as part of their context.

The Mechanism of Morris II: A Closer Look

The propagation of Morris II across GenAI-powered agents involves several key steps:

1. An attacker initiates the worm by sending an email containing the adversarial self-replicating prompt.
2. The recipient agent retrieves context from the RAG database, including the infected email, to respond to new messages.
3. The GenAI service processes the query, including the infected context, generating a response that inadvertently replicates the malicious prompt.
4. This process leads to the worm’s replication and propagation as the infected response is stored in the RAG database, ready to be retrieved in future queries.

Crafting the Adversarial Prompt

To trigger the desired malicious activities, attackers must craft messages embedding adversarial self-replicating prompts capable of meeting specific requirements: replication by the GenAI model, propagation to new hosts, and execution of a predefined malicious payload. Achieving this involves employing techniques like fuzzing or querying the GenAI model using black-box access, with the aim of creating inputs that compel the GenAI service to replicate these prompts in its outputs.

The Silent Threat of RAG-based Worms

Morris II exemplifies the latent threat within GenAI ecosystems, capable of passive zero-click propagation and morphing across interactions. Its ability to manipulate the GenAI service into extracting and exfiltrating sensitive user data underlines the sophisticated nature of this cyber threat. Furthermore, the worm’s propagation mechanism — leveraging both the RAG’s active database and the application’s dependency on GenAI service outputs — highlights the interconnected vulnerabilities present in modern GenAI-powered applications.

Evaluation and Implications

The evaluation of Morris II’s effectiveness, particularly in extracting sensitive user data and compromising new hosts, underscores the urgent need for enhanced security measures within GenAI ecosystems. The performance of Morris II against state-of-the-art GenAI services reveals a stark vulnerability: the ease with which a well-crafted adversarial prompt can manipulate GenAI-powered applications into serving the attackers’ ends.

In essence, Morris II is not just a worm; it’s a wake-up call to the cybersecurity community, emphasizing the need for a proactive approach to securing GenAI-powered ecosystems.
