Premoum hive defender3/11/2023 ![]() In the case of this malware, the activity groups strongly associated with Winnti are BARIUM and LEAD. Microsoft labels activity groups using code names derived from elements in the periodic table. Microsoft Threat Intelligence associates Winnti with multiple activity groups-collections of malware, supporting infrastructure, online personas, victimology, and other attack artifacts that the Microsoft intelligent security graph uses to categorize and attribute threat activity. To test how Windows Defender ATP can help your organization detect, investigate, and respond to advanced attacks, sign up for a free trial. We then discuss how centralized response options, provided as enhancements to Windows Defender ATP with the Windows 10 Creators Update, can be used to quickly stop threats, including stopping command and control (C&C) communication and preventing existing implants from installing additional components or from moving laterally to other computers on the network. We go through the Winnti implant installation process and explore how Windows Defender ATP can capture such attacker methods and tools and provide visualized contextual information that can aid in actual attack investigation and response. To show how this breach and similar breaches can be mitigated, we look at how Windows Defender Advanced Threat Protection (Windows Defender ATP) flags activities associated with BARIUM, LEAD, and other known activity groups and how it provides extensive threat intelligence about these groups. We look at how these activity groups introduce the implant to various targets and techniques used by Microsoft researchers to track the implant. In this blog, we look at the Winnti malware implant as used by two known activity groups BARIUM and LEAD. According to the German press, the intruders used the Winnti family of malware as their main implant, giving them persistent access to the conglomerate’s network as early as February 2016. When a Germany-based industrial conglomerate disclosed in December 2016 that it was breached early that year, the breach was revealed to be a professionally run industrial espionage attack.
