Japanese entities experienced 114 damaging ransomware attacks in the first half of the year, up 87% from the year before, the National Police Agency said Thursday.

Of the reported ransomware cases, in which attackers demanded payment in exchange for restoring access to company data made unavailable via encryption, 59 targeted small or midsize companies, while 36 were large corporations. They included 37 manufacturers, 20 service companies and five hospitals, according to the agency.

In one of the cases reported in the six months through June, Toyota was forced to suspend operations at all 14 of its domestic plants for one day after parts supplier Kojima Industries was hit by a ransomware attack on Feb. 28.
