Phishing is an integral part of red teaming. Using documents with
macros and DDE has come to be in bad taste. Luckily, a lot
of companies use MS Exchange as a corporate mail server. The
use EWS makes the users’ life easier and really helps red team
specialists. A regular MS Office document allows the researcher to obtain
a user’s password, as well as to gain complete control
over his MS Exchange mailbox.
This report is about the tool developed by our team, which works with
all modern Microsoft OS versions and allows you to implement an NTLM-relay
attack on MS Exchange Server via both SMB and HTTP. A convenient
logging and flexible configuration systems allows you to produce phishing
campaigns qualitatively and quickly.
