A global wave of cyberattacks and data breaches that began in January 2021 after four zero-day vulnerabilities, known collectively as ProxyLogon, were discovered in Microsoft Exchange Server, giving cybercriminals full access to user emails and passwords, administrator privileges on the server, and access to connected devices on the same network. In August 2021, a set of vulnerabilities known as ProxyShell were found.
