Wordpresscan is a Wordpress CMS security auditing tool which is rewritten WPScan in Python and implemented some idea of WPSeku by swissky. However, the original copy in Github is still in alpha version and dated Oct 15, 2017.
Wordpresscan is then forked by Samiux on Apr 19, 2018 and some improvements as well as bugs fix on it. The modified version is released in Open Source under GPLv3 by Samiux.
It is well tested on Parrot Security OS 3.11 and it can run right away on Parrot without installation.
