Malicious LLM's: A Practical Guide
Understanding the Threat Vectors:
Malicious LLMs like FraudGPT and WormGPT possess capabilities reported to encompass writing malicious code, creating ‘undetectable malware’, generating phishing pages, crafting hacking tools, identifying vulnerable targets, and more. While much has been exaggerated about their malware-writing capacity, MaLLMs do pose tangible risks to organisations, albeit through known threat vectors. Therefore, organisations should have mechanisms in place for detection, containment, and recovery from MaLLM threats.
Now, let's delve into the heart of the matter by mapping these threat vectors to the MITRE ATT&CK framework.
Mapping Threat Vectors to MITRE ATT&CK:
While the increasing arsenal of MaLLM's available to threat actors raises concerns, you'll find reassurance in knowing that your security program is well-equipped to detect and defend against many of these LLM threat vectors. In this section, you are presented a comprehensive matrix designed to:
Understanding Malicious LLM Threats-Highlight specific threat vectors, such as 'Crafting Spear Phishing Email'
Mapping to MITRE ATT&CK-Show how these threats align with the MITRE ATT&CK framework for better recognition and categorization.
Highlight MITRE Tactics-Delve into the tactics involved, like 'Initial Access,' to provide a comprehensive view of the MaLLM threat landscape.
Understanding Downstream Risks-Explore the downstream potential losses associated with each threat vector.
Effective Mitigating Controls-Cover potential mitigating controls.
The Impact of Known Attack Vectors
While it's true that malicious LLMs do not presently provide threat actors with entirely new attack vectors, they are increasing the potential quality and volume of threats. This, in turn, could result in costly impacts on organisations globally. To illustrate this point, let's review some relevant data from the 2023 IBM Ponemon: Cost of a Data Breach report, which highlights the significant financial repercussions of known initial attack vectors.
Conclusion
In summary, keeping pace with Malicious LLMs is no small task. However, this pragmatic approach to mapping threat vectors to mitigating controls through MITRE ATT&CK can significantly reduce susceptibility to MaLLM-driven attacks.
Consider these key takeaways:
- MaLLMs amplify known threat vectors, warranting vigilant defence.
- Your security program likely has the tools to detect and mitigate these threats.
- Regularly assess your defences, verify mitigating controls, and adapt to evolving risks.
