Prompts used in large language models (LLMs) are emerging as critical indicators of compromise (IOCs) in cybersecurity, highlighting how threat actors exploit these technologies for malicious purposes. The article reviews a recent report from Anthropic detailing various misuse cases of the AI model Claude and emphasizes the need for threat analysts to focus on prompt-based tactics, techniques, and procedures (TTPs) for effective monitoring and detection. The author proposes the NOVA tool for detecting adversarial prompts tailored to specific threat scenarios.

Google has launched Sec-Gemini v1, an experimental AI model aimed at enhancing cybersecurity by providing advanced reasoning capabilities and real-time knowledge to support cybersecurity workflows. This model outperforms existing benchmarks and is available for research collaboration with select organizations to help shift the balance in favor of cybersecurity defenders.

AI is transforming the cybercrime landscape by enhancing existing attack methods rather than creating new threats, making cybercriminal activities more efficient and accessible. The panel at RSA Conference 2025 emphasized the importance of adapting defense strategies to counter AI-driven attacks, highlighting the need for international cooperation and innovative security frameworks. As AI continues to evolve, both defenders and threat actors will need to adapt rapidly to the changing dynamics of cyber threats.
