Domestic companies, including Osaka Metropolitan University, have suffered cyberattacks, and the threat of ransomware demanding a ransom has become commonplace. Osaka Metropolitan University has announced that classes will resume, while personal information may have been leaked.
Osaka Metropolitan University was hit by a cyberattack and had suspended classes, but resumed them from the 9th. The attack is believed to have involved ransomware demanding a ransom, and the university says personal information of approximately 130,000 people may have been leaked.
IT journalist Mikami Yo (三上 洋) pointed out that the current state of the university's security has not been fully investigated, and said that international criminal groups may be aware of the lax security at Japanese companies and the fact that ransoms have been paid.
At Osaka Information and Computer Vocational School, students experienced a demonstration of what happens when a cyberattack occurs during work. The demonstration showed how the screen changes when an attachment is opened and lock icons appear on desktop icons.
