PowerShell is an interactive command-line shell offering flexibility to system administrators. Simply put, WBEM makes it easier for you to remotely manage many computers by standardizing how system management information is retrieved. WMI is the Microsoft implementation of Web-Based Enterprise Management (WBEM), which is a technology used in enterprise environments for accessing management information.

Subscribing to Windows Management Instrumentation (WMI) events. The updated scripts can leverage two PowerShell methods to maintain persistence: Let’s cover each category a bit more to see how these different stages unfold, then focus on some takeaways from each phase. The Turla group updated the scripts to include three main characteristics maintaining persistence, decryption, and loading embedded executables or libraries into memory. Previously, researchers from Kaspersky have seen the Turla group use PowerShell loaders based on an open-source project called Posh-SecMod. I’m going to break down how these attack works. They have a very notable line up of victims as highlighted in their post. Turla, the attackers in this case, are a force to be reckoned with. This post delves into Eset’s research and the foul usage of Windows’ PowerShell scripting language, which attackers often use for fileless malware. We believe this prediction came true early. The WatchGuard Threat Lab predicted a general rise of fileless malware during 2019, but more specifically forecasted that you would see fileless malware incorporate automatic network spreading techniques to create a new threat we call a vaporworm. #POWERSHELL CRYPTO LOCKER SOFTWARE#
Fileless malware is malicious software that only runs directly in computer memory, making it more difficult for traditional malware products to detect. Eset researchers recently revealed some rather sophisticated fileless malware samples that cyber criminals use.
