Empire PowerShell is a type of malware, harmful software designed to exploit and damage computer systems. It can infiltrate a system through suspicious downloads, emails, or websites, often unbeknownst to the user. Once inside, it can steal personal information, disrupt operations, or even hold data hostage for ransom. This particular malware was detected as early as September 2017, according to Daron Hartvigsen, a cybersecurity specialist for DFIN. Further Empire PowerShell activity was detected in November 2019, indicating continued unauthorized intrusions.
In 2020, the group responsible for the Empire PowerShell attacks switched their tactics, moving away from the Empire PowerShell framework due to its lack of updates from the original creators. Instead, they began using CobaltStrike for lateral movement activity. This set of domains is used as a Command & Control (C&C) center by the group, leveraging a custom loader to execute their malicious activities.
A customized version of the CobaltStrike loader has been observed, which is possibly intended as a replacement for the previously used Empire PowerShell framework. This shift in tactics suggests an evolution in the group's strategy, making it crucial for organizations to stay updated with the latest cybersecurity threats and mitigation strategies. The continued detection of Empire malware activity underscores the persistent nature of these threats and the importance of robust cybersecurity measures.
