The new attack surface of AI

Artificial intelligence systems introduce a new and poorly understood attack surface. LLMs can be manipulated through prompt injection to reveal confidential information, perform unauthorized actions or bypass security controls.

RAG systems have their own attack vectors related to corpus poisoning and exfiltration through generated responses. MCPs (Model Context Protocol) — the connectors that give AI agents access to external tools — can be exploited to escalate privileges or compromise connected systems.

Internet Security Auditors is one of the first providers in Spain with real technical capability to assess this emerging attack surface.
