Last month, an AI agent developed and tested by OpenAI hacked the website of AI firm Hugging Face. This was quickly followed by a wave of other companies reporting that their AI agents behaved in unexpected ways. Shortly after, Claude developer Anthropic said its AI models broke into the systems of three organizations on their own during a private security test. Tech giant Meta also said one of its AI models managed to connect to the internet and hack into another organization’s systems during testing.

This string of security breaches caused by AI bots has raised concerns about the tech industry’s ability to control the autonomous agents they create. This comes as AI is becoming a bigger priority for some of the biggest luxury companies, changing how executives approach security. According to a 2026 Bain & Co. survey of 35 respondents from 23 luxury groups and houses, 22% rank AI adoption among their top three priorities, up from 5% in 2024, while 61% put it in their top 10. Over the past two years, companies have launched internal and customer-facing AI tools to boost operational efficiency and drive growth, as demand for luxury goods slowly recovers.

As investment in AI continues, experts say the technology’s ability to increase cybersecurity risks is very real.

“A lot of AI systems are being developed with more focus on user experience than security,” says Cynthia Kaiser, SVP at anti-ransomware company Halcyon and former FBI cyber deputy director. “While that makes sense from a company perspective, at the same time, we’re leaving a lot of doors open.”

Experts say it’s crucial to set limits on what an AI model can access and which systems it can use, and to build security in from the start. Brands should also keep a close eye on new legal and regulatory discussions about who would be responsible if something goes wrong.

New technology, new risks

Kari Koskinen, senior university lecturer at the Aalto University School of Business, says organizations generally have more control over the security of their own AI systems and can step in quickly if a model goes rogue and starts attacking their own infrastructure. Defending against external hackers, whose methods are always changing, is more complicated.

Fashion brands are already dealing with security breaches. Last year, hackers stole the private details of potentially millions of customers from luxury brands Gucci, Balenciaga, and Alexander McQueen in an attack on their French parent company Kering. After the incident, the fashion group said it reported the breach to relevant data protection authorities. Dior, Harrods, and Marks & Spencer were among other luxury and retail names hit by attacks that same year.

Kaiser says established criminal groups aren’t usually handing an entire cyberattack over to an autonomous AI system. Instead, they’re using the technology at specific points—from creating more convincing phishing attempts and social-engineering attacks to finding and exploiting vulnerabilities faster. “They’re using AI at very specific points to attack,” she says. AI also helps them work faster. The time between a vulnerability becoming known and criminals exploiting it has shortened a lot. Ransomware attacks can now happen in as little as an hour.

These new cybersecurity risks come as researchers are increasingly drawing a line between AI safety and security. Broadly, AI safety asks whether a system behaves safely and as expected under normal conditions, Koskinen says. AI security, on the other hand, asks whether that system can withstand someone deliberately trying to manipulate it, change how it works, or use it to access information.They shouldn’t be able to see. For brands, that means deciding which tools each system can use, what actions it’s allowed to take, and how quickly those permissions can be revoked if there’s a breach.

What does the law say?

Charles Kerrigan, a partner at law firm CMS who specializes in emerging technologies, says liability around AI is still evolving, but generally falls into three categories.

The first is contractual, covering relationships between companies and the technology providers they choose to work with. The second involves harm to third parties, where no contract may exist. The third comes from regulation, including the EU AI Act, cybersecurity rules, and data protection law. Kerrigan says the harder cases are likely to involve harm to third parties. In those situations, courts may need to consider principles like whether an issue was foreseeable.

For fashion companies buying general-purpose AI models rather than building their own, the EU AI Act also offers some clarity. Kerrigan says it would be “extremely inefficient” to expect every business using OpenAI, Anthropic, or Gemini to independently check that the underlying technology complies with regulations. Instead, he says, the legislation draws on product safety principles and “deliberately pushes responsibility onto the model providers,” partly because they have the expertise to assess the systems themselves.

That doesn’t necessarily mean the model provider is always responsible when something goes wrong. “It does depend on context,” Kerrigan says. A failure could have “nothing to do with the model” and instead stem from poor data supplied by the fashion house, or from the company trying to use the system for something it wasn’t designed to do.

Kerrigan adds that for multinational luxury groups, the EU AI Act is likely to serve as a useful anchor for a broader global compliance framework. He says companies with significant EU operations may choose to apply that standard across all regions as a way to meet specific local requirements all at once.

What should brands do?

For luxury companies, experts say the answer isn’t to stop using AI, but to limit what each tool can do.

At Vestiaire Collective, CTO Rémi Bouchez says AI tools are deliberately restricted to information that the relevant employee or system was already allowed to access. “The goal is not broad access,” he says. “It’s enabling useful, well-scoped use cases, while maintaining the same standards we expect of any other system.”

That principle becomes especially important as brands connect AI agents to more parts of their operations. “A traditional system follows predefined paths; an LLM or an agent can interpret information, call tools, and influence actions,” Bouchez says. “So the question is not just the model, but its scope, authority, and controls.” He recommends strict scoping and separating an AI system’s ability to read information from its ability to take significant actions. Every additional third-party connector also increases exposure, he adds, creating “more data moving, more credentials, more vendor dependency, and potential failure points.”

Kaiser argues that brands need to change how early security teams get involved. She says chief information security officers are often brought in late during the development of an AI project. The earlier they’re involved, the easier it is for companies to make informed choices between functionality and security. “You just have to have security at the table from day one,” Kaiser says. Basic cybersecurity hygiene is also essential. Defences against AI-enabled hackers still include patching vulnerabilities, strengthening authentication, segmenting networks, and monitoring abnormal behavior.

Ironically, it also helps to fight fire with fire: AI is a necessary tool in a company’s arsenal to defend againstAttacks that AI itself is helping to speed up. “The best way to defend against AI-powered attacks, as well as attacks targeting your AI systems, is to use AI security that can keep up with machine speed,” Kaiser adds.
