Australia has become the latest country to ban government officials from using software made by Russian cybersecurity firm Kaspersky, arguing that the software poses an “unacceptable security risk.” Government agencies have until April 1 to remove all existing instances of Kaspersky software on government systems and devices. The move sees Australia become the latest member of the Five Eyes intelligence pact of countries to announce restrictions on Kaspersky software, joining Canada, the United Kingdom, and the United States.
