FBI Reports Third ShinyHunters Arrest as AI Raises Questions About the Future of Hacking Crews

The Register · 12 Oct 2026
Key Takeaway Treat personal and staff data as a prime target for extortion groups, and keep software patched quickly, because AI-assisted discovery of flaws may shorten the time between a bug being found and being exploited.

The FBI has announced what appears to be a third arrest in its investigation of ShinyHunters, a cyber extortion group. According to The Register's podcast discussion, the FBI director said agents had arrested another suspected co-conspirator of the group. The announcement was made on X and emailed to news reporters. One earlier arrest was reportedly made at the end of last month.

The arrests relate to a late September breach of FBI systems. The hosts say the stolen data included details about agents and people who wanted to be hired by the Bureau, such as names, jobs, physical locations and emergency contact information. The source excerpt does not say how many people were affected.

The episode also covers a second vulnerability found by Anthropic's Mythos model that has been exploited in the wild. The Register describes it as a flaw humans probably would not have discovered, and the hosts ask how important human attackers will be in the future of cybercrime. The excerpt is only the opening of the discussion, so further detail on the bug and the arrests is not covered here.
