Meta has confirmed that thousands of Instagram accounts were hacked by exploiting a vulnerability in its AI chatbot, which allowed hackers to reset passwords and take control of accounts. The breach, which occurred between April 17 and this week, was discovered after media reports and has resulted in Meta notifying at least 20,225 people that their accounts had been compromised. The company has disabled the AI chatbot and removed the code path that allowed the chatbot to reset user accounts. The breach has raised concerns about the security of Meta's AI systems and the potential for similar vulnerabilities in the future.
