Title: Russian Intelligence Agency Accesses Microsoft Executives’ Email System
Microsoft has reported a significant security breach, revealing that a Russian intelligence agency, allegedly involved in the SolarWinds attack, gained unauthorized access to the email system of the company’s executives. The breach, which occurred in late November 2023, affected a small percentage of Microsoft corporate email accounts, including those belonging to senior leadership, cybersecurity personnel, legal teams, and other functions. This intrusion resulted in the exfiltration of some emails and attached documents, with the initial target being information related to the Midnight Blizzard incident.
Details of the Breach:
According to Microsoft’s investigation, the threat actor employed a password spray attack to compromise a legacy non-production test tenant account, which provided them with a foothold into the system. Leveraging the permissions of this compromised account, the hackers managed to access a limited number of email accounts belonging to top-level personnel within the company. It is worth noting that the breach did not compromise Microsoft’s entire email infrastructure, but rather a specific segment of accounts targeted by the attackers.
