Antivirus & Firewall: The 10 Most Dangerous Internet Attacks

In the night from May 6th to 7th, 2020, the IT department of the Ruhr University Bochum noticed massive disruptions in network traffic, which indicated a hacker attack. The security officers then shut down the servers in the university’s central administration to prevent the virus from spreading further and damaging and deleting data. The Exchange and Sharepoint servers were particularly affected by the virus attack, but the VPN access to the university systems also temporarily stopped working. As a result of the attack, the university’s internal mail system failed, and numerous services were no longer available to students working externally. Since the university was only online because of the corona crisis, teaching was severely restricted.
