'Criminal' Cyberattack Disables Computer Systems at Los Angeles Schools

The massive cyberattack that disabled computer systems across the Los Angeles Unified School District school over the weekend is “criminal in nature,” but most all online services — including key emergency systems — were operating safely, no ransom demands were made and schools opened with only a few glitches, Supt. Alberto Carvalho said. Besides taking the district’s website offline, the attack resulted in staff and students losing access to email.
