Microsoft Threat Actor is ‘Sourgum’ from Israel Bringing Malware to Windows, Who Are They?

Microsoft identified “Sourgum” from Israel as the threat actor behind its Windows malware and zero-day, which plagued its computer operating system in the past weeks. The particular problem has only been solved recently by Microsoft, and it gave them the struggle to fix with different users saying that it was not effective for their experience.

Microsoft: Threat Actor is ‘Sourgum’ from Israel

According to Microsoft’s blog post, the company’s investigation in their recent cyberattack and zero-day vulnerability was from an Israeli private sector company, “Sourgum.” The said company is known to be a PSOA or a private sector offensive actor, which has a purpose to sell “cyberweapons” to its clients, with the intentions of hacking them.

Another group name they were discovered to be is known as “Candiru,” and they have been related to Sourgum with regards to the recent Microsoft attack. While the intentions of Candiru remain unknown, it is a direct threat against Microsoft and would be subject to an investigation, catching the criminal behind the attack. 

Bill Marczak and other authors from Citizen Lab have detailed how they caught Candiru and other threat actors which have taken part in the attack on Microsoft.

Speculations that both are the same company ensues, but it was a different discovery for Microsoft and Citizen Lab.

Who is ‘Sourgum?’

Is Microsoft Windows Safe Now?

The attack cost Microsoft a lot, and it has been known to be immune to several of its emergency patch releases which failed when its users and the public needed it most. That being said, this threat was a massive deal for Microsoft, especially as the company has struggled to protect its operating systems and return to normal proceedings. 

Currently, Microsoft’s systems have been given a patch to protect themselves from the vulnerabilities, and will soon add more layers of protection.
