Windows Defender ATP thwarts Operation WilySupply software supply chain cyberattac

Earlier this week, the research team which is part of Windows Defender Advanced Threat Protection system, detected several attacks being carried out against a software’s update system whose name has not yet been revealed – All that is known about the software is that it is a well-known editing application and that the creator or vendor of the software also experienced attacks.

The consequences of the attack: It is said that the attackers, by hacking the software update system, were able to gain remote access to certain targeted computers. They were then able to execute malware without the victim knowing about the infection.
