The Lapsus$ hacker syndicate adds to the long list of victims, after claiming to have successfully hacked Nvidia, Samsung, et al, now they are also claiming to have successfully hacked Microsoft.
They showed off a file containing some of Microsoft's Bing and Cortana source code that was up to 37GB in size, we quoted from The Verge.
Microsoft then investigated the claims and found that a syndicate they referred to as DEV-0537 hacked into a single account and stole some of the sources of some of their products.
In a post on Microsoft's security blog, investigators have been detecting the Lapsus$ syndicate for several weeks, and reveal a number of methods used to infiltrate victims' systems.
According to the Microsoft Threat Intelligence Center (MSTIC), the main purpose of the DEV-0537 is to gain access through stolen credentials that allow them to steal data, as well as carry out destructive attacks on certain organizations, which often leads to extortion.
Microsoft also ensured that the impact of the theft of the source code was not too fatal and their security team claimed to have succeeded in stopping the hackers while they were in action.
Lapsus$ has recently become a dangerous syndicate targeting a number of large companies. Call it Samsung and Nvidia, whose important data was successfully stolen.
Meanwhile, for Microsoft, this is not the first time they have conceded the source code. Previously there was a SolarWinds attack, where Microsoft also claimed that the source code was successfully accessed by hackers.
According to Lapsus$, they only get 45% of the source code for Bing and Cortana, and about 90% of the source code for Bing Maps.
For now, Microsoft said they would continue to monitor the movement of Lapsus$ regarding possible follow-up attacks on Microsoft customers.
