The University of California San Francisco (UCSF) suffered a Netwalker ransomware attack that was discovered in early June when the operators behind Netwalker posted to their leak site about it. Information from the school of medicine was accessed and some was encrypted. In an announcement by the school they stated, “we quarantined several IT systems within the School of Medicine as a safety measure, and we successfully isolated the incident from the core UCSF network. Importantly, this incident did not affect our patient care delivery operations, overall campus network, or COVID-19 work.” While the investigation is still being carried out, UCSF has decided to pay $1.14 million USD to the Netwalker operators in exchange for the stolen data and the tools to decrypt the data that was encrypted during the attack.
