Russian hackers target aid groups in new cyber-attack, says Microsoft

Microsoft says another wave of Russian cyber-attacks has targeted government agencies and human rights groups in 24 countries, most in the US.

It said about 3,000 email accounts at more than 150 different organisations had been attacked this week.

The group responsible was the same one that carried out last year's SolarWinds attacks, which Russia's Foreign Intelligence Service (SVR) is accused of orchestrating, Microsoft said.

Russia has denied both cyber-attacks.

The Kremlin on Friday said it had no knowledge of the latest hacks, and called on the US tech giant to answer further questions, including how it was linked to Russia.
