Microsoft says 'Russia-linked group' is attacking its internal systems again: What is different this time

Microsoft reports ongoing unauthorized access attempts by Midnight Blizzard, also known as Nobelium, targeting internal systems and source code repositories. They are actively investigating and assisting customers in mitigating measures against the attack. Midnight Blizzard is also said to have increased the volume of some aspects of the attack, such as password sprays, by as much as 10-fold in February, compared to the large volume seen in January.
