 # et-tu-brute
-A fast CSRF token-fetching bruteforce tool
+### It's March 15th, Julius CSRF.
+Unhappy with the slowness of available Python token-fetching bruteforcers, I created et-tu-brute to allow for easy, ultrafast multithreaded attacks on CSRF-protected login portals.
+
+Tested against a Proving Grounds machine with a CSRF-protected web portal, et-tu-brute clocked ~120,000 password attempts in 9 minutes. Add it to your toolkit to directly attack CSRF logins at a rapidfire rate, no proxy or long wait required. 
+
+It also handles huge wordlists well, loading 1gb+ password lists with no slowdown or long initial wait.
+## Usage
+```
+./ettubrute <login_url> <csrf_htmlname> <wordlist> <postdata_nocsrf> <username> <errormsg>
+```
+Here's an example with the values filled in:
+```
+./ettubrute http://10.10.11.77/login csrf_token /usr/share/wordlists/rockyou.txt 'user=^USER^&password=^PASS^&submit=Login' admin 'Your username and password mismatch.'
+```
+The tool will automatically try to grab cookies from the login page as well. It was developed for a single PHPSESSID cookie, so multiple cookies set on the token grab might break that functionality; I'll need to test it against login pages that set multiple cookies to see how it performs.
+## Compiling
+I've provided a compiled amd64 binary. If you'd like to compile the tool yourself, run the following:
+```
+git clone https://github.com/the-emmon/et-tu-brute
+cd et-tu-brute
+nim c --threads:on --opt:speed --app:console --gc:boehm -d:release ettubrute.nim
+```
+Be sure to compile with the options listed to avoid glitches and "illegal filesystem access" crashes.
+
+If you'd like to directly mirror the release builds, strip the executable like this:
+```
+strip ettubrute && upx --best --strip-relocs=0 ettubrute
+```
