Risk to Business: 2.337 = Severe

The Lapsus$ gang has released 37GB of source code that they snatched in a brazen hit on Microsoft’s Azure DevOps server. Microsoft confirmed the incident, saying that the threat actors gained access through a compromised employee account. The source code looks to pertain to various internal Microsoft projects, including for Bing, Cortana and Bing Maps. Microsoft made a blog post about its recent operations to track and potentially interfere with Lapsus$ last week. The company was quick to state, “Microsoft does not rely on the secrecy of code as a security measure and viewing source code does not lead to elevation of risk.” Lapsus$ is known to be a ransomware outfit, but no ransom activity was disclosed in this incident.

Risk to Business: 1.299 = Extreme

Lapsus$ also pulled off another high-profile attack, this time against access management company Okta. Lapsus$ announced that it had breached Okta’s security in January on March 22. Supporting the claim, the group published screenshots related to Okta’s internal apps and systems. This one had a bit of a bumpy acknowledgment process by Okta who originally said no customer data was accessed but later clarified, saying “a small percentage of customers – approximately 2.5% – have potentially been impacted and (their) data may have been viewed or acted upon.” A third-party service provider’s previous breach likely also played a part in the incident. No specifics on the data were given. As we stated above, Lapsus$ is typically involved in ransomware operations but no details of any ransomware activity have been reported.

Russian meat wholesaler Miratorg Agribusiness Holding has suffered a major cyberattack that encrypted its IT systems.
