2021 Microsoft Exchange Server data breach

A global wave of cyberattacks and data breaches began in January 2021 after four zero-day exploits were discovered in Microsoft Exchange Servers, giving attackers full access to user emails and passwords on affected servers.

In March 2021, it was estimated that 250,000 servers fell victim to the attacks, including servers belonging to around 30,000 organizations in the United States, 7,000 servers in the United Kingdom,[1] as well as the European Banking Authority, the Norwegian Parliament, and Chile's Commission for the Financial Market (CMF).[2][3][4][5][6][7]
