Sideloading a malicious DLL via a legitimate, signed executable.
Once the DLL is loaded, it typically performs the following:
: Archives or folders located in %APPDATA% or %TEMP% .
: The malicious payload. Because it shares the same name as a dependency the .exe expects, the OS loads this local file instead of the legitimate one in C:\Windows\System32 .
Upon extraction, the archive typically reveals three primary files designed to work in tandem:
: Because the process ( wtvlvr.exe ) is a trusted, signed binary, many AV/EDR solutions may not immediately flag the malicious activity occurring within its memory. Payload Behavior
If you are analyzing this on a system, look for these indicators of compromise (IOCs):
