Dive Brief:
Microsoft plans to make significant changes to its internal security practices after disclosing a hack by the state-sponsored threat group Midnight Blizzard, which stole emails and other data from senior-level Microsoft executives and other employees, the company said Friday in a filing with the Securities and Exchange Commission.
The hackers compromised a legacy non-production test tenant account to gain access to the company, Microsoft said. The threat actor used the account’s permissions to reach a “very small percentage” of emails and attachments of senior executives and employees in the cybersecurity, legal and other departments.
The actor, formerly known as Nobelium, was behind the 2020 Sunburst attacks against SolarWinds and other companies. U.S. authorities raised alarms about Midnight Blizzard in December after the actor was found exploiting unpatched vulnerabilities in JetBrains TeamCity servers across the globe.
