Central Piedmont Community College, an institution with 50,000 students in Charlotte, North Carolina, has canceled classes after a cyberattack disabled key systems used for remote learning.

Students, staff and faculty were notified earlier this year that a malicious actor had accessed sensitive data, prompting an upgrade to multi-factor authentication.

The company revised its story last week, but it's still not saying which universities were affected by the cyberattack discovered last May.

Administrators said they were able to restore all encrypted data from backups, but they decided to pay the ransom to prevent student and teacher information from being leaked onto the internet.

Code embedded in an official university website selling Spartan-branded sweatshirts and mugs compromised financial information of about 2,600 customers.

Fraudulent emails claiming to have important information on the current health crisis is installing malware and stealing log-in credentials from universities.

Gadsden Independent School District is working to restore systems after being hit by the same ransomware virus for the second time in less than a year.

Classes began days late on Wednesday as Wallace State Community College and federal authorities investigate what took many of its systems offline.

Students were told to stay home as staff at Richmond Community Schools work to restore functionality to heating, telephone and other critical systems.
