Hartford Mayor Luke Bronin said the hacker or hackers indicated it was a ransomware attack, but only left an email address to contact and made no specific ransom demand. The problem was discovered Saturday and numerous systems were affected, including one used to communicate transportation routes and live information to school bus drivers.
Tuesday was supposed to be the first day of school for the district of about 18,000 students. Both in-person and remote learning have now been pushed back by the attack, officials said. A new start date has not been announced.
