Third US College Hit with Ransomware Attack in a Week

Columbia College, Chicago has become the third US college in a week to fall victim to a cyber-attack involving the Netwalker family of ransomware. The Illinois educational establishment, along with Michigan State University and the University of California, San Francisco, was targeted by cyber-criminals and given six days to pay a ransom to recover its files.





Netwalker, also known as Mailto or as an updated version of Kokoklock ransomware, was first observed operating in September 2019. The malware works by encrypting data and renaming files with the developer’s email address and an extension made up of the victim’s unique ID.


Like the attack on the University of California, the assault on Columbia occurred on June 3, exactly one week after Michigan State University was hit. On the Netwalker blog, the cyber-criminals claimed to have exfiltrated “very highly sensitive data like social security numbers and other private information” from Columbia.
