How Does InvisiMole Spyware Works
Initially, InvisiMole Spyware launching through hijacking the DLL(Dynamic-link Library) using the method called DLL Hijacking.
It has both 32-bit and 64-bit versions of the malware and both variant using persistence technique to working with both architectures.
Apart from the DLL Hijacking it using another entry point by exporting the function called GetDataLength which help to launch the payload.
Malware authors cleverly set to zero values PE timestamps manually so the exact time of the compilation is unknown.
Attackers encrypting the strings, internal files, configuration data and network communication to make it more stealthy and maintain the Persistence.
Later the module communicate with its C&C server even if there is a proxy configured on the infected computer and it also has an ability to communicate with C2 server using locally-configured proxies if the connection is unsuccessful.
According to ESET, After successfully registering the victim with the C&C server, additional data are downloaded, which are to be interpreted on the local computer as backdoor commands.
Commands will perform to collect some basic system information and it added the spyware future into the system.
