Microsoft accuses 'state-backed' Chinese hackers over email cyber attacks

Microsoft says it has identified a group of hackers with links to the Chinese government that have been waging a cyber attack campaign targeting its Exchange email server software. The tech giant says the Hafnium cyber espionage group has been trying to steal data from businesses and organisations, and is urging all users to update their systems with the latest security patches. But first, British Finance Minister Rishi Sunak is set to unveil the government's next budget, as the country faces the mounting economic cost of the Covid-19 pandemic.
