National Security Alert Issued After Hackers Leak CIA's Top-Secret Claude Code

The US Federal Bureau of Investigation (FBI) has issued a warning after hackers posted the long-theorized “Claude” code online as part of a leak that also included sensitive information about a wiretap tool used by the agency. The hackers, who have been linked to a series of high-profile cyberattacks in recent months, claim to have accessed highly classified information through the FBI’s vulnerability management system. The attack is being described as one of the most significant breaches of national security seen in years, with experts warning that the leak poses a major risk to sensitive intelligence gathered by the CIA and other US spy agencies. The hackers also posted additional tools and malware, including Cisco source code stolen from the company’s repositories, suggesting an ongoing supply chain attack. The FBI has confirmed that it is investigating the breach, but has yet to disclose further details about what exactly was compromised or how the attackers managed to gain access to sensitive information.
