# Exploit: Advanced Host Monitor 11.92 beta - Local Buffer Overflow (EggHunter) #

# Date: 2019-03-18 #

# Author: Peyman Forouzan #

# Tested Against: Winxp SP2 32-64 bit - Win7 Enterprise SP1 32-64 bit - Win10 Enterprise 32-64 bit #

# Software Download #1: https://www.ks-soft.net/download/hm1192.exe #

# Software Download #2: https://www.ip-tools.biz/download/hm1192.exe #

# Version: 11.92 beta #

# The Program also has SEH Overflow, Which can be implemented in a similar way #

# Special Thanks to my wife #

# Steps : Open the APP --> Tools --> Trace (or Telnet) --> paste in contents from the egg.txt into "Host" --> Start --> Close #

# Advanced Host Monitor --> Options --> Startup --> paste in contents from the egghunter-winxp-win7.txt or #

# egghunter-win10.txt (depend on your windows version) into "load specific HTML file" --> Save --> Wait a litle --> #

# Shellcode (Calc) open #

#------------------------------------------------------------------------------------------------------------------------------------#

# "Egg" shellcode into memory --> Egghunter field overflow: EIP overwrite #
