In the first nine months of the year, ransomware infections have hit over 500 US schools, according to a report published last week by cyber-security firm Armor.

In total, the company said it found and tracked ransomware infections at 54 educational organizations like school districts and colleges, accounting for disruptions at over 500 schools.

To make matters worse, the attacks seem to have picked up in the last two weeks, with 15 school districts (accounting for over 100 K-12 schools) getting hit at the worst time possible — in the first weeks of the new school year.
