Microsoft has confirmed ongoing attempts to remove elite Russian government hackers who infiltrated the email accounts of senior company executives in November. The hackers, affiliated with Russia's SVR foreign intelligence service, have been utilizing stolen access data to target customer networks. Microsoft revealed that the hackers leveraged data obtained in the intrusion to compromise source-code repositories and internal systems.
The company refrained from specifying the exact source code accessed or the extent of the hackers' capabilities to further compromise customer and Microsoft systems. It was disclosed that the hackers pilfered cryptographic secrets, such as passwords, certificates, and authentication keys, from email communications between Microsoft and undisclosed customers.
