REDMOND, WA (MyBellinghamNow.com) – State-backed Russian hackers broke into Microsoft’s corporate email system and accessed the accounts of the company’s leadership team members.
Microsoft said the intrusion began in late November and was discovered on Jan. 12th.
A very small percentage of Microsoft corporate accounts were accessed, and some emails and attached documents were stolen.
Microsoft said it was able to remove the hackers’ access from the compromised accounts on or about Jan. 13th.
Its investigation indicates the hackers were initially targeting email accounts for information related to their activities.
Microsoft said the hackers from Russia’s foreign intelligence agency were able to gain access by compromising credentials on a test account.
In an August blog post, Microsoft described how its threat-intelligence team discovered that the same Russian hacking team had used the technique to try to steal credentials from at least 40 different global organizations through Microsoft Teams chats.
