CNN —Russian state-backed hackers gained access to some of Microsoft’s core software systems in a hack first disclosed in January, the company said Friday, revealing a more extensive and serious intrusion into Microsoft’s systems than previously known.
Hackers with access to source code can use it for follow-on attacks on other systems.
Microsoft first revealed the breach in January, days before another Big Tech company, Hewlett Packard Enterprise, said the same hackers had breached its cloud-based email systems.
The hacking group was behind the infamous breach of several US agency email systems using software made by US contractor SolarWinds, which was revealed in 2020.
US officials have attributed the hacking group to Russia’s foreign intelligence service.
