University College London, one of the U.K.’s prestigious public research universities, has closed off access to personal and shared drives after a ransomware attack was detected late Wednesday afternoon.
University officials said this morning that this was a web-based infection, reversing claims made in the early hours of the attack that the ransomware was executed via a phishing email attachment.
“Our current hypothesis is that the malware infection occurred through users visiting a website that had been compromised rather than being spread via email attachments,” university officials said. “However this remains unconfirmed at the moment.”
