2.1 Hollow Process Injection Steps

The following steps describe how malware normally performs process hollowing. Let’s assume that there are two processes, A and B. In this case, process A is the malicious process and process B is the legitimate process (also known as a remote process) such as explorer.exe:

• Process A starts a legitimate process, B, in the suspended mode. As a result of that, the executable section of process B is loaded in the memory, and the PEB (Process Environment Block) identifies the full path to the legitimate process. The PEB structure's ImageBaseAddress field points to the base address where the legitimate process executable is loaded.
• Process A gets the malicious executable that will be injected into the remote ...
