Ruhr University Bochum (RUB) forced to shut down large parts of its central IT infrastructure after a ransomware attack. RUB suspects that the attackers used Windows malware to infect the university’s systems. Students and employees are advised to limit the usage of Windows-based applications to the most necessary communication processes, not to open any email attachments, and to send documents that need to be shared as PDFs. It is currently unknown if any data belonging to students, employees, or researchers was accessed or exfiltrated.
