For the second time in a week, Houston County Schools in Alabama had to delay their school year's opening due to a malware attack and the ongoing recovery. It has not been disclosed what type of malware attack they were hit with, but sounds like a ransomware attack based upon the details given.

Originally scheduled to start the school year on August 1st, a malware attack has taken down all of the computer and phone systems, making it difficult to get the school ready to open.
