Software giant Microsoft revealed in mid-January 2024 that its systems were successfully infiltrated at the end of 2023 by Russia-backed hacking group Midnight Blizzard, as part of a coordinated and targeted information-gathering exercise.
Microsoft confirmed the details of the attack in a statement published online on Friday 19 January 2024, where it revealed the attack was first detected on 12 January 2024 and the immediate activation of its internal response processes meant it was able to immediately remove the hackers from its systems.
“To date, there is no evidence that the threat actor had any access to customer environments, production systems, source code, or AI [artificial intelligence] systems,” said Microsoft in its statement.

This is a key question because a company’s risk profile should be under continuous, ongoing re-assessment in any event, and the flurry of recent Microsoft hacks ought to be on their risk radar.
It is not clear how (or even if) Microsoft will be able to 100% guarantee its entire cloud environment is now clean and free from hackers, and they’ve reported being attacked successfully multiple times by Chinese and Russia-backed hacking groups.
Are we relying on the same security controls as Microsoft do?
Microsoft disclosed the Midnight Blizzard hackers were inside its systems for up to 42 days before they were…
