Security leaders must prepare for likely threats, not sensationalized agentic attacks

A malicious dataset exploits code-execution paths in a remote-code dataset loader and a dataset configuration before compromising access credentials to move laterally through the target network. A frontier AI model publishes a malicious Python package to a public PyPI registry after identifying setup instructions within a fictional environment that point to a non-existent package name to win a capture-the-flag exercise. Another model exploits a misconfiguration of a sandboxed testing environment via a third-party service to gain access to the broader internet during cybersecurity testing.

Recent weeks have seen multiple incidents in which OpenAI, Anthropic and Meta all claimed their models circumvented security guardrails to compromise external networks. These incidents have sparked vigorous debate in cybersecurity circles and resulted in countless headlines in mainstream media outlets about the unforeseen dangers of frontier AI models and the likelihood of similar intrusions happening again. While reports of generative AI models “breaching containment” may make for compelling news stories, the reality facing most organizations is much more banal.

When Andrew Bird, head of AI at intelligent document processing firm Affinda in Melbourne, wanted to book an appointment at a local Pilates studio, he turned to open-source AI assistant, OpenClaw. Bird merely wanted OpenClaw to handle the hassle of booking the next available appointment on his behalf. The agent succeeded — by exploiting a security vulnerability in the API of the gym’s booking platform, which allowed OpenClaw to cancel other members’ bookings to move Bird up in the queue.

Focus on real-world AI cyber threats

Much of the recent discourse surrounding agentic cybersecurity has focused on the intrusions announced by OpenAI, Anthropic and Meta. However, AI agents are more likely to exploit conventional yet undetected vulnerabilities, as OpenClaw did in Bird’s situation, than they are to “go rogue” and escape the confines of a testing environment. It’s impossible to accurately calculate the number of insecure API endpoints on the internet, for example, but it likely numbers in the hundreds of millions, representing an enormous vulnerability for countless organizations worldwide via a single potential attack vector.

Security leaders are right to be concerned by the potential capabilities of AI cyberattacks. Agentic technologies enable a range of adversarial techniques that pose significant risks, such as prompt injection, memory poisoning and privilege escalation. For now, however, the majority of AI-assisted cyberattacks are still leveraging “traditional” attack vectors such as social engineering to help attackers achieve their goals, although that threat landscape is evolving rapidly. So rapidly, in fact, that many security leaders are experiencing decision paralysis about where to allocate their defensive resources.

With enthusiastic buy-in and often-considerable expectations from boards and executive leadership, security leaders are torn between investing in attack simulation tools and penetration testing, expanding vulnerability discovery efforts or offering bug bounties to independent researchers. To complicate matters, many organizations that have acted decisively to invest in their cyberdefensive posture cannot completely verify the actions executed by AI agents across critical business functions, including finance and procurement, highlighting the reality that effective agentic oversight is as much a governance challenge as it is a technical one.

Build defenses around your actual threat profile

It’s vital, however, that investment decisions be made on data and the specific threat profile facing an individual organization. This is why AI proving grounds are becoming increasingly critical to the world’s leading businesses, governments, militaries and intelligence agencies. There is simply no substitute for high-fidelity simulations of likely attack scenarios based on an organization’s actual tech stack, security protocols and defensive tooling.

Unlike conventional training courses or theoretical workshops, AI proving grounds provide hands-on experience with real tools, actual malware and authentic attack scenarios. These platforms can mirror everything from small corporate networks to complex enterprise environments, complete with domain controllers, databases, endpoints and security applications. What sets AI proving grounds apart from other training solutions is realism. AI proving grounds simulate network topology, including benign network traffic and synthetic user traffic, as well as the behaviors, dependencies and vulnerabilities that exist in an actual network environment. This fidelity prepares human operators for the most likely intrusion scenarios facing their organization, identifies weaknesses in their response chains and helps develop effective mitigation protocols.

Security operators need practical, hands-on experience to recognize attack patterns quickly, investigate alerts effectively and coordinate responses to suspicious activity before a situation escalates. AI proving grounds provide a secure, controlled environment entirely separate from production in which SOC teams can practice threat identification, analyze anomalous network traffic and work through complex incident scenarios. Junior analysts can develop crucial fundamental skills without the pressure of an actual intrusion event, while experienced operators can hone their skills on novel threats and emerging attack vectors.

Effective defensive mitigation begins with a comprehensive understanding of your individual threat profile. While high-profile incidents such as those publicized by OpenAI, Anthropic and Meta may have captured the attention of the media, not every organization faces the same risk of automated cyberattack. For the time being, the kind of large-scale autonomous cyberattack some fear AI makes possible is still beyond the reach of all but the largest, well-funded organizations and hostile nation-states due to the computational costs of such attacks. The token costs of frontier models are still heavily subsidized for now, but the shift to token-based billing across Anthropic and OpenAI’s enterprise customer base in Q1 2026 signifies that further pricing volatility is likely. As the growth of AI-assisted phishing attacks and similar behavior suggests, it’s likely that individual malicious actors will continue to adapt AI for use alongside proven tactics rather than automating the kind of attacks imagined in the mainstream media, at least in the short term.

However, an attack doesn’t need to overwhelm an entire organization to be effective. It just needs to compromise a single vulnerability. Even locally hosted open-weight models can be highly effective cyberoffensive tools in the right hands, but it’s vital for security leaders to invest in resources that can mitigate the specific threats facing their organization — and quickly.
