Introduction
In a recent alert to the public and industry, OpenAI has raised the alarm over the growing cybersecurity risks posed by its upcoming AI models. As these systems become more powerful and autonomous, the company is acknowledging that they might enable a new class of cyber threats — and is calling on the community to prepare.
Summary of the Report
OpenAI’s latest internal evaluations show a rapid jump in the cyber-capabilities of its frontier AI models. For example, the model GPT‑5 scored just 27% on a “capture-the-flag” (CTF) cybersecurity exercise in August 2025, but its successor, GPT‑5.1-Codex-Max, reached 76% in a similar test last month.

Because of this steep improvement, OpenAI warns that future models could soon reach what it defines as “High” levels of cybersecurity capability. In non-technical terms, that means they might be able to discover real zero-day vulnerabilities, craft remote exploits against well-defended systems, or assist in complex intrusion operations — including attacks on industrial or enterprise infrastructure.

Recognizing this “dual-use” nature — where the same tools could help defenders or attackers — OpenAI says it’s ramping up its internal security posture. The company is investing in building defensive tools, offering secure-access programs for vetted cybersecurity professionals, developing infrastructure hardening, and launching an advisory group called the Frontier Risk Council. This council will bring together experienced cyber-defense experts and security practitioners to guide risk assessment and mitigation efforts.

At the same time, OpenAI says it still cannot guarantee when — or which — of its future models will officially be classified as “High risk,” or what shape those models might take.

What Undercode Say:
The decision by OpenAI to publicly flag the cybersecurity risk of its own models is a double-edged moment for the industry. On one hand, it signals maturity — a recognition that AI isn’t just about convenience, creative tools, or productivity boosters anymore. These are powerful systems whose misuse can have serious, real-world consequences. By warning the public proactively, OpenAI helps shift the conversation from reactive patchwork to proactive defense and awareness.
But this is also a wake-up call. The leap — from 27% to 76% performance on a CTF benchmark — suggests the pace of progress is not just significant; it’s exponential. That means traditional cybersecurity strategies, often built around human-led code reviews, penetration tests, and threat hunting teams, might soon be outpaced by AI-driven attackers. Cybersecurity professionals and policy makers should understand that the attack surface is expanding — not just in quantity, but in sophistication.
Moreover, the fact that OpenAI feels the need to build an advisory council tells us that even those creating the technology are not fully confident about where its power could lead. The “defensive AI tools” they promise may help, but they assume widespread adoption, rigorous oversight, and rapid deployment — challenges in the fragmented and fast-moving world of cybersecurity.
We also should not overlook the possibility of a “race to the bottom.” As AIs get more capable, other labs or malicious actors might skip the safeguard steps. The pressure, incentives, and sometimes commercial competition may lead to newer models being released without sufficient scrutiny. Theoretical checks and frameworks — even well-designed ones — lose effectiveness if they aren’t adopted industry-wide.
In short: AI is now firmly in the domain of cybersecurity. Those who ignore it — companies, governments, or individuals — could be caught off guard.
Fact Checker Results:
OpenAI indeed reported improved cybersecurity performance from GPT-5 to GPT-5.1-Codex-Max (from 27% to 76%) on capture-the-flag tests.

The “High” risk categorization refers to the potential for zero-day exploits and complex intrusion assistance, not necessarily an immediate guarantee that any model will act maliciously.

OpenAI is putting in place multiple mitigation measures — including a Frontier Risk Council, defensive tooling for defenders, and infrastructure hardening — as part of its risk-management strategy.

Prediction
Looking ahead, we expect a few developments: first, an increase in AI-powered cybersecurity tools — from automated vulnerability scanning to AI-driven patch suggestions — as defenders leverage the same tools that can be used offensively.
Second, regulatory pressure and industry standards will likely intensify. As the risks become more visible, governments and international bodies may push for stricter rules on AI release, monitoring, and dual-use oversight.
Third, we may see a growing market for “AI-hardened infrastructure” — networks, software, and services explicitly built to resist AI-enabled attacks. Companies that move early to adopt these protections will likely gain competitive advantage.
Finally, the race will accelerate. As defensive tools improve, attackers — state or non-state actors — will seek to harness AI’s power, forcing security teams into a constant game of cat and mouse. The only sustainable advantage may come from collaboration: shared threat intelligence, community standards, and cross-industry cooperation.
