While the network didn't elaborate on the breach, feds told The Wall Street Journal that it was a ransomware attack. That presumably means some bad actors tried to extort money from the company by holding its system hostage. But since the FBI is still looking into the event, it's still unclear how the hackers infiltrated the channel's system.

Ransomware attacks have become increasingly common these recent years, with hackers attacking and extorting even huge corporations like FedEx and government offices like Atlanta's. Investigators later found that the ransomware used to attack the Georgia capital was also used to extort hospitals, health care companies and state agencies.
