Tech giant Microsoft has confirmed that one of their employees was compromised by the Lapsus$ hacking group, allowing the threat actors to access and steal portions of their source code.

The Lapsus$ gang released 37GB of source code stolen from Microsoft’s Azure DevOps server. The source code is for various internal Microsoft projects, including for Bing, Cortana, and Bing Maps.

In a new blog post published tonight, Microsoft has confirmed that one of their employee’s accounts was compromised by Lapsus$, providing limited access to source code repositories.

“No customer code or data was involved in the observed activities. Our investigation has found a single account had been compromised, granting limited access. Our cybersecurity response teams quickly engaged to remediate the compromised account and prevent further activity,” explained Microsoft in an advisory about the Lapsus$ threat actors.

“Microsoft does not rely on the secrecy of code as a security measure and viewing source code does not lead to elevation of risk. The tactics DEV-0537 used in this intrusion reflect the tactics and techniques discussed in this blog.”

“Our team was already investigating the compromised account based on threat intelligence when the actor publicly disclosed their intrusion. This public disclosure escalated our action allowing our team to intervene and interrupt the actor mid-operation, limiting broader impact.”

While Microsoft has not shared how the account was compromised, they provided a general overview of the Lapsus gang’s tactics, techniques, and procedures (TTPs) observed across multiple attacks.
