Microsoft has disclosed that it's detected a spike in credential-stealing attacks conducted by the Russian state-affiliated hacker group known as Midnight Blizzard.
The intrusions, which made use of residential proxy services to obfuscate the source IP address of the attacks, target governments, IT service providers, NGOs, defense, and critical manufacturing sectors, the tech giant's threat intelligence team said.
Midnight Blizzard, formerly known as Nobelium, is also tracked under the monikers APT29, Cozy Bear, Iron Hemlock, and The Dukes.
The group, which drew worldwide attention for the SolarWinds supply chain compromise in December 2020, has continued to rely on unseen tooling in its targeted attacks aimed at foreign ministries and diplomatic entities.
