New research shows that the Christmas Day attack, which affected the United States and Britain, was orchestrated by Russia.
The attack was also designed to damage American business and national pride, the research suggests.
A report published in the British Journal of Political Science on Tuesday found that the cyberattack occurred on December 19, 2016, in response to the United Kingdom’s decision to leave the European Union.
“Our research has identified an important Russian influence operation in which Russian military-technical experts used cyberwarfare techniques to conduct the attack against the United Sates,” lead author Nicholas Carr, a researcher at the University of Sussex, said in a statement.
“The attack targeted UK and US government websites.
The attackers also exploited vulnerabilities in the UnitedS.
public internet infrastructure to target US government and corporate websites.”
The attack affected over 6 million users in the US, UK, Canada, Germany, Australia, New Zealand, and South Africa, and affected up to 30,000 other sites, according to the researchers.
The researchers also found that Russian military intelligence had also taken part in the attack, as well as the development of other cyberwarcraft attacks, including a DDoS (distributed denial of service) attack that targeted a number of US and British websites.
The report is the latest research on Russian cyberattack capabilities, following a separate study published in February.
