Kremlin hackers accessed Microsoft’s internal systems

Microsoft said on Friday that Russian state-sponsored hacking group Midnight Blizzard have gained access to some of its source code repositories and internal systems, after a hack that was detected by the US company in January.

The hackers have increased the volume of some aspects of the attack by as much as 10-fold in February, compared to the already large volume we saw in January 2024, Microsoft said.

It added that Midnight Blizzard is attempting to use secrets of different types it has found that were shared with customers.

In January, Midnight Blizzard was detected trying to infiltrate the tech giant’s corporate systems.

“The Microsoft security team detected a nation-state attack on our corporate systems on January 12th, 2024, and immediately activated our response process to investigate, disrupt malicious activity, mitigate the attack, and deny the threat actor further access,” Microsoft revealed in the January 19th SEC filing.
