Russian State-Sponsored Hackers Breach Microsoft Executive Emails

Russian intelligence group Nobelium, responsible for the SolarWinds breach, accessed some of Microsoft's top executives' email accounts in a recent attack. The group exfiltrated emails and documents from a small percentage of corporate email accounts, including those of senior leadership and employees in cybersecurity and legal functions. Microsoft does not believe customer data, production systems, or proprietary source code were accessed. The attack comes amidst ongoing conflict between Russia and Ukraine, and follows new U.S. requirements for disclosing cybersecurity incidents. Microsoft is continuing its investigation and working with law enforcement and regulators.
