Federal investigators put out a warning late Tuesday to the nation’s school systems after a series of high-profile ransomware attacks on their computer networks.
The most recent publicized incident involved the country’s second-largest school system – the Los Angeles Unified School District. Over the weekend, the district’s IT team recognized an attempted hack on the system and had to quite literally pull the plug to prevent any further data compromise.
“It’s undeniable that, if we had not number one detected this anomaly, and responded by alerting our law enforcement partners, and brought in all the extra police that we have brought on board so quickly, it could have been a catastrophic set of circumstances that we would be facing today,” said Alberto Carvalho, the Superintendent of Los Angeles’ schools.
In a ransomware attack, the perpetrator gains control of data, or even an entire system, and demands a ransom to relinquish control.
