The Microsoft logo is seen at its local headquarters in Beijing on July 20, 2021, the day after the US accused Beijing of carrying out cyber attack on Microsoft and charged four Chinese nationals over "malicious" hack in March.
The tech giant has earlier begun its investigation of a potential hacking incident involving its cloud platform, Azure.
On top of that, before Microsoft started its investigation LAPSUS$ claimed to have hacked the tech giant. It simultaneously leaked some screenshots of sensitive data supposedly belonging to the Windows maker.
Microsoft Confirms LAPSUS$ Hack
As per a news story by The Verge, the extortion group behind the recent massive hacking incident involving Samsung and Nvidia has posted 37GB worth of files, which the gang claims to be source code for the search engine of Microsoft, Bing, and its virtual assistant, Cortana.
This time around, upon the investigation of Microsoft, it now confirms that "a single account" got compromised, allowing the hackers, dubbed by the tech firm as DEV-0537, to steal some source code of its services.
However, the giant firm said that the said account only granted the hackers "limited access." It also added that its cybersecurity team had already contained the compromised "single account," preventing further hacking activities.
The Microsoft logo is illuminated on a wall during a Microsoft launch event to introduce the new Microsoft Surface laptop and Windows 10 S operating system, May 2, 2017 in New York City. The Windows 10 S operating system is geared toward the education market and is Microsoft's answer to Google's Chrome OS.
What's more, the software tech giant went on to assure the public that both the code and data of its customers are not part of the recent hacking incident based on the investigation of the firm.
Microsoft also explained that exposing its source code to the public eye does not carry any risk, noting that it "does not rely on the secrecy of code as a security measure."
Microsoft and LAPSUS
It also turns out that the tech behemoth has been tracking the LAPSUS$ hacking group for weeks already, The Verge noted in the same report.
In fact, Microsoft has already learned some of the ways of the extortion group in infiltrating its targets. The tech firm even disclosed it in its recent security blog post.
