FBI reports another ShinyHunters arrest as AI finds exploited vulnerability
The FBI says it has arrested another suspected co-conspirator linked to the ShinyHunters cyber extortion group.
The arrest appears to bring the number connected to the investigation to three.
The case concerns a late-September breach of FBI systems that exposed information about agents and people seeking FBI jobs, including names, work details, locations and emergency contacts.
ShinyHunters claimed it had taken data from everyone, but that claim has not been confirmed.
Separately, Anthropic’s Mythos AI model found a second software vulnerability that was later exploited in real attacks.
The discussion raised the possibility that AI could find weaknesses human hackers might miss, changing the role of people in cybercrime and cybersecurity.
The FBI has not provided further details about the latest arrest in the information described here.
