The FBI has arrested another person it believes is tied to ShinyHunters, the hacking group that broke into the bureau's jobs website and stole data about its workers.

"This is the latest arrest this FBI has made in a matter of days involving this network," FBI Director Kash Patel said Friday. He did not name the suspect.

A U.S. official and another source told CBS News the suspect was detained in Pennsylvania. A law enforcement source said he is a Canadian citizen who is believed to be directly involved in the hack. Canada's national police said they were aware of the arrest but would not comment.

The hack happened in September. The group said it took 2 to 3 terabytes of data about FBI workers by using a weakness in Oracle PeopleSoft, a human resources program, CBS News reported. Some veteran agents have called it the worst breach of a federal system since a 2015 hack exposed more than 22 million government records. An internal FBI memo said officials were assuming all current and former employees were exposed, USA Today reported, citing Reuters.

Earlier this week, the FBI said a contractor had failed to install a security fix on the system that was attacked, and that the contractor was removed.

The bureau says ShinyHunters often breaks into outside vendors that run cloud services, steals data and then threatens to publish it unless victims pay. FBI Assistant Director Brett Leatherman said the group has breached more than 140 organizations and taken at least $70 million in payments, USA Today reported.

Other suspects have been caught recently. Dutch police arrested a 24-year-old man in Amsterdam in September, and Jordanian authorities detained another suspect last weekend. Officials say others are still at large.
