Osaka University suffered from a data breach incident that exposed personal data of 80,000 people. The university's computer system was fraudulently accessed many times from outside using the ID and password of one lecturer. According to the university, a manager's ID was acquired through the access sessions and then used to install malware that stole data. The compromised information includes names, identification numbers and email addresses. The stolen information also contained lists of donors to the university and pay records. They investigated the incident and all computer system users changed their password as a countermeasure.
