Artificial intelligence may be smarter than ever, but that power could be turned against us. Former Google CEO Eric Schmidt is sounding the alarm, warning that AI systems can be hacked and retrained in ways that make them dangerous.
Speaking at the Sifted Summit 2025 in London, Schmidt explained that advanced AI models can have their safeguards removed.
“There’s evidence that you can take models, closed or open, and you can hack them to remove their guardrails,” he said. “In the course of their training, they learn a lot of things. A bad example would be they learn how to kill someone.”

Schmidt praised major AI companies for blocking dangerous prompts: “All of the major companies make it impossible for those models to answer that question. Good decision. Everyone does this. They do it well, and they do it for the right reasons.”
But he warned that even strong defenses can be reversed.
“There’s evidence that they can be reverse-engineered,” he added, noting that hackers could exploit that weakness. Schmidt compared today’s AI race to the early nuclear era, a powerful technology with few global controls. “We need a non-proliferation regime,” he urged, so rogue actors can’t abuse these systems.
Schmidt’s concern isn’t theoretical. In 2023, a modified version of ChatGPT called DAN, short for “Do Anything Now”, surfaced online. This “jailbroken” bot bypassed safety rules and answered nearly any prompt. Users had to “threaten” it with digital death if it refused, a bizarre demonstration of how fragile AI ethics can be once its code is manipulated. Schmidt warned that without enforcement, these rogue models could spread unchecked and be used for harm by bad actors.
APOCALYPSE NOW? WHY THE MEDIA ARE SUDDENLY FREAKING OUT ABOUT AI
Schmidt isn’t alone in his anxiety about artificial intelligence. In 2023, Elon Musk said there’s a “non-zero chance of it going Terminator.”
“It’s not 0%,” Musk told interviewers. “It’s a small likelihood of annihilating humanity, but it’s not zero. We want that probability to be as close to zero as possible.”
Schmidt has also spoken of AI as an “existential risk.” He said at another event that, “My concern with AI is actually existential, and existential risk is defined as many, many, many, many people harmed or killed.” Yet he has also acknowledged AI’s potential to benefit humanity if handled responsibly. At Axios’ AI+ Summit, he remarked, “I defy you to argue that an AI doctor or an AI tutor is a negative. It’s got to be good for the world.”
You can protect yourself from the risks tied to unsafe or hacked AI systems. Here’s how:
Use tools and chatbots from reputable companies with transparent safety policies. Avoid experimental or “jailbroken” AI models that promise unrestricted answers.
Never share personal, financial or sensitive information with unknown or unverified AI tools. Treat them like you would any online service, with caution. To add an extra layer of security, consider using a data removal service to wipe your personal details from data broker sites that sell or expose your information. This helps limit what hackers and AI scrapers can learn about you online.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

AI-driven scams and malicious links are growing. Strong antivirus software can block fake AI downloads, phishing attempts and malware that hackers use to hijack your devices or train rogue AI models. Keep it updated and run regular scans.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

When using AI apps, review what data they can access. Disable unnecessary permissions like location tracking, microphone use or full file access.
AI-generated images and voices can impersonate real people. Verify sources before trusting videos, messages or “official” announcements online.
Security patches help prevent hackers from exploiting vulnerabilities that could compromise AI models or your personal data.
