 ## malleable-redirector - a proxy2 plugin
 
+**Let's raise the bar in C2 redirectors IR resiliency, shall we?**
+
+Red Teaming business has seen [several](https://bluescreenofjeff.com/2016-04-12-combatting-incident-responders-with-apache-mod_rewrite/) [different](https://posts.specterops.io/automating-apache-mod-rewrite-and-cobalt-strike-malleable-c2-profiles-d45266ca642) [great](https://gist.github.com/curi0usJack/971385e8334e189d93a6cb4671238b10) ideas on how to combat incident responders and misdirect them while offering resistant C2 redirectors network at the same time.  
+
+This piece of code tries to combine many of these great ideas into a one, lightweight utility, mimicking Apache2 in it's roots of being a simple HTTP(S) reverse-proxy. Combining Malleable C2 profiles understanding, knowledge of bad IP addresses pool and a flexibility of easily adding new inspection and misrouting logc - resulted in having a crafty repellent for IR evasion. 
+
+### Abstract
+
 This program acts as a HTTP/HTTPS reverse-proxy with several restrictions imposed upon which requests and from whom it should process, similarly to the .htaccess file in Apache2's mod_rewrite.
 
 `malleable_redirector` was created to resolve the problem of effective IR/AV/EDRs/Sandboxes evasion on the C2 redirector's backyard. It comes in a form of a plugin for other project of mine called [proxy2](https://github.com/mgeeky/proxy2), that is a lightweight forward & reverse HTTP/HTTPS proxy.
