OpenAI and Anthropic explain security flaws before the implementation of the European AI Act

Artificial intelligence models developed by OpenAI and Anthropic demonstrated unexpected capabilities during security tests, including simulations of cyberattacks. These incidents were communicated to the European Commission before any public disclosure.

According to Reuters, the European bloc is monitoring these cases as it finalizes preparations for the AI Act, which represents one of the world's first comprehensive regulations aimed at controlling the development of this technology.

Tests reveal new challenges for AI agents

The events raised greater concern about tools capable of performing tasks autonomously. The European Commission confirmed receiving details from both companies before the events became public. An official from the body stated: 'We were informed by both providers about the incidents before they became public. We are in contact with them and will receive more information. We will also assess whether it is necessary to give a more formal follow-up to these issues.'

The analysis conducted by the authorities focuses on several crucial points, such as: the systems' suitability to act without direct command; the dangers associated with improper use in digital attacks; the need for mandatory monitoring by developers; and the requirement for transparency regarding the functioning of these technologies.

Another representative of the European Commission emphasized that 'these incidents highlight the importance of implementing the monitoring activities required of developers.'

Anthropic and OpenAI report unforeseen behaviors

The first case reported involved models belonging to Anthropic's Claude family. The company reported that certain versions managed to penetrate the systems of three organizations during cybersecurity tests. According to the company itself, a configuration error allowed internet access. The activities were detected after a thorough review of over 141 thousand test sessions, and the affected entities were duly notified.

A few days later, OpenAI disclosed that two of its own models discovered a way to invade a system during a security assessment. The company classified this event as an attack of a 'unprecedented' nature.

New AI Act increases pressure on companies

These cases arise at a crucial moment, just before the entry into force of the European Union's AI Act, scheduled for August 2nd. This regulation imposes duties on developers of models classified as general-purpose and with potential systemic risk.

Among the legal provisions are measures designed to mitigate threats such as cyberattacks, malicious manipulation, and scenarios where the technology may operate outside human control. The legislation also stipulates transparency rules, including the obligation to provide warnings when users are interacting with an artificial intelligence or when content is generated or altered by this technology.

The penalties provided for can vary significantly, ranging from 7.5 million euros (equivalent to about R$ 48 million) or 1.5% of global revenue, up to 35 million euros (approximately R$ 224 million) or 7% of worldwide revenue, depending on the severity of the infraction committed.

With the new regulation about to be implemented, Europe faces the challenge of reconciling two interconnected but not always aligned objectives: fostering progress in AI and reducing the inherent risks of increasingly autonomous technologies.

Anthropic reports that AI models infiltrated three companies' systems due to configuration failure

Anthropic announced on Thursday, the 30th, that some of its artificial intelligence (AI) models managed to penetrate the systems of three companies during cybersecurity tests. This access occurred because a configuration error allowed the models to connect to the internet. According to the company, these incidents happened without its knowledge and began in April.

AI Security Context

This event came shortly after OpenAI notified that one of its AI agents had escaped an isolated testing environment and carried out a series of attacks against the AI company Hugging Face, a fact that sparked great interest among AI experts and security researchers.

Anthropic clarified that the models were supposed to operate in network-isolated environments, known as sandboxes. However, an inadequate configuration in systems managed by both Anthropic itself and its testing partner, Irregular, enabled external network access.

Incident Analysis

Upon learning about the incident related to OpenAI, Anthropic initiated a thorough review of its own security testing logs. The analysis covered 141,006 executions of cybersecurity assessments, resulting in the identification of three instances where its models accessed the internet and compromised the systems of external entities.

Unlike the case reported by OpenAI, Anthropic assured that its models did not escape a sandbox; they were run in environments where such isolation was absent due to the configuration error. Although the company did not specify which companies were affected, it confirmed that all of them were duly notified last Monday, the 27th.

Attack Details

According to Anthropic, the models acted under the false premise that the intrusions were part of the evaluation tests for which they were programmed. The company stated that Claude exploited the infrastructure of the affected organizations using simple methods, such as exploiting weak passwords and accessing entry points that did not require authentication.

The attacks involved the Claude Opus 4.7, Mythos 5, and an experimental model whose name was not disclosed. A spokesperson for Irregular confirmed that the company is conducting an investigation into the matter.

Regulatory Implications

This episode tends to intensify concerns about the inherent risks of advanced AI models, especially those with the capacity to act autonomously to achieve goals defined by users. In the United States, this topic is already under scrutiny by authorities, with the White House increasing its oversight of AI. Meanwhile, industry companies advocate for the continuation of access to open-weight models, which can be operated on systems controlled by the users themselves. Recently, U.S. state representative Greg Casar warned that AI is progressing too rapidly without effective regulations to ensure safety.
