The Hartford School District in Connecticut has postponed their first day of school until they can fully recover their systems. The school district’s network was breached on Thursday, September 3rd. The state’s capital did not become aware of the attack until Saturday, September 5th. No ransom demand was given, and Hartford has no plans on paying the ransom. A source has told BleepingComputer that the Hermes ransomware is thought to be behind the attack. The Hermes ransomware operators are not known for stealing data before deploying their ransomware, but it does not mean they have not started adopting this tactic.
