As I have been exploring the accelerative power of AI in various forms over the past few months, I have been arriving at the conclusion that this is a form of grand sorcery. I jest … sort of … but in some respects I think this is an apt analogy.

Like all grand sorcery, AI is powerful stuff. But also, like all grand sorcery, we don't understand it well. It is becoming pretty clear that, in many respects, at this stage, we don't know what we don't know.

This applies, in particular, to securing AI in our enterprises.

There is a growing tension between our desire to use this powerful technology and the need to do so with the appropriate guard rails. To complicate things, emerging regulatory frameworks (the EU AI Act, for example) now have to be adhered to. The challenge for many enterprises in securing their companies and adhering to these frameworks is whether they have the technologies in place to help them meet these obligations.

The rise of Generative AI (GenAI) introduces a range of new vulnerabilities that malicious actors can exploit. As we integrate AI more deeply into our business operations, monitoring our use of AI, and understanding the security risks accompanying this powerful technology is crucial.

Let me give you some examples.

The Invisible Threat: Unicode Exploitation

A fascinating yet concerning aspect of AI security involves the exploitation of invisible text through quirks in the Unicode standard. AI models can recognize these invisible characters but remain unseen by human users, creating a covert channel for attackers to conceal and exfiltrate sensitive data. This vulnerability opens the door to prompt injection attacks, where hidden commands can be injected into AI prompts, potentially compromising confidential information.

The GenAI Attack Chain

To better understand how these vulnerabilities manifest, it’s essential to explore the GenAI attack chain, which outlines the steps attackers may take to exploit AI systems:

1. Bypassing Guardrails: Attackers often begin by circumventing the model’s built-in safeguards. Techniques such as encoding and token manipulation allow them to mask malicious inputs, making it easier to exploit system vulnerabilities.

2. Privilege Escalation: Once attackers bypass these defences, they can escalate their privileges through direct and indirect prompt injections. This enables unauthorized control over the model, leading to potential security compromises.

3. Security Compromise: The culmination of these actions can result in severe consequences, including sensitive data leakage, phishing attacks, and operational disruptions. Attackers can access critical systems, spread malicious code, and disrupt business operations.

Real-World Implications

Proof-of-concept attacks have demonstrated how invisible text can extract sensitive data from AI tools, such as Microsoft 365 Copilot. These incidents highlight the urgent need for organizations to prioritize understanding these security challenges. It's also becoming clear that sensitive data, including personally identifiable information (PII) and corporate secrets, can be exploited for identity theft or corporate espionage, leading to significant financial and reputational damage.

Addressing the Risks

As leaders, we must strike the right balance here. Find ways to embrace and leverage this technology while ensuring robust security measures and keeping people informed and well-educated about potential vulnerabilities. Understanding the GenAI attack chain and the risks associated with invisible text exploitation is critical for safeguarding sensitive information.

Conclusion

I'm pretty excited by AI's transformative capability. However, as we start to harness its potential, it’s imperative that we collectively understand and address the risks inherent in this new form of sorcery.
