I track US public school cybersecurity incidents and this represents a change in tack for ransomware attackers vis-a-vis schools. Clark County (Las Vegas) is only 1 of 3 school districts since the start of the school year compromised with ransomware alongside the exfilitration of student/employee data. The others include Fairfax County (VA) and Haywood County (NC). Overall, I count 35 instances of ransomware (K-12 districts) for all of 2020; 15 of those publicly disclosed since August 1, 2020.

PS The latest incident, with commentary from the district superintendent: "Got to work this morning, powered up my computer and the first message I got was you’ve been encrypted. Basically, you know, the same old thing…you’ll have to pay us in bitcoin, we’re holding your data ransom, you need to contact this email address."
