# This tool connects to the given Exchange's hostname/IP address and then
|
|
# by collects various internal information being leaked while interacting
|
|
# with different Exchange protocols. Exchange may give away following helpful
|
|
# during OSINT or breach planning stages insights:
|
|
# - Internal IP address
|
|
# - Internal Domain Name (ActiveDirectory)
|
|
# - Exchange Server Version
|
|
# - support for various SMTP User Enumeration techniques
|
|
# - Version of underlying software such as ASP.NET, IIS which
|
|
# may point at OS version indirectly
|
|
#
|
|
# This tool will be helpful before mounting social engieering attack against
|
|
# victim's premises or to aid Password-Spraying efforts against exposed OWA
|
|
# interface.
|
|
#
|
|
# OPSEC:
|
|
# All of the traffic that this script generates is not invasive and should
|
|
# not be picked up by SOC/Blue Teams as it closely resembles random usual traffic
|
|
# directed at both OWA, or Exchange SMTP protocols/interfaces. The only potentially
|
|
# shady behaviour could be observed on one-shot attempts to perform SMTP user
|
|
# enumeration, however it is unlikely that single commands would trigger SIEM use cases.
|
|
#
|
|
# TODO:
|
|
# - introduce some fuzzy logic for Exchange version recognition
|
|
# - Extend SMTP User Enumeration validation capabilities
|
|
#
|
|
# Requirements:
|
|
# - pyOpenSSL
