+## **Agent Perry**
+
+### **Challenge description**
+
+
+"Oh! Hey Agent P, so, this is your 100th battle with Doofenshmirtz. We planted a spyware in Evil Incorporated's network so that we could trace something. We sense he's planning something dangerous. You know what to do, good luck! [Monogram Out]
+"
+
+### **Short writeup**
+
++ Access Doof's evailbank IP after network scan
++ Dump the .git folder
++ Retrieve Doof's fileserver pasword from older commit
++ Login via FTP, upload reverse shell
++ Using `sudo -l` list all the commands the user can execute
++ Use sed to edit `/etc/passwd`
+  - `sed -i "$ a norm ALL=(root) NOPASSWD:ALL" /var/blueprints/../../../etc/sudoers`
++ Login to root and get the flag

+# This is the main Apache server configuration file.  It contains the
+# configuration directives that give the server its instructions.
+# See http://httpd.apache.org/docs/2.4/ for detailed information about
+# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
+# hints.
+#
+#
+# Summary of how the Apache 2 configuration works in Debian:
+# The Apache 2 web server configuration in Debian is quite different to
+# upstream's suggested way to configure the web server. This is because Debian's
+# default Apache2 installation attempts to make adding and removing modules,
+# virtual hosts, and extra configuration directives as flexible as possible, in
+# order to make automating the changes and administering the server as easy as
+# possible.
+
+# It is split into several files forming the configuration hierarchy outlined
+# below, all located in the /etc/apache2/ directory:
+#
+#       /etc/apache2/
+#       |-- apache2.conf
+#       |       `--  ports.conf
+#       |-- mods-enabled
+#       |       |-- *.load
+#       |       `-- *.conf
+#       |-- conf-enabled
+#       |       `-- *.conf
+#       `-- sites-enabled
+#               `-- *.conf
+#
+#
+# * apache2.conf is the main configuration file (this file). It puts the pieces
+#   together by including all remaining configuration files when starting up the
+#   web server.
+#
+# * ports.conf is always included from the main configuration file. It is
+#   supposed to determine listening ports for incoming connections which can be
+#   customized anytime.
+#
+# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
+#   directories contain particular configuration snippets which manage modules,
+#   global configuration fragments, or virtual host configurations,
+#   respectively.
+#
+#   They are activated by symlinking available configuration files from their
+#   respective *-available/ counterparts. These should be managed by using our
+#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
+#   their respective man pages for detailed information.
+#
+# * The binary is called apache2. Due to the use of environment variables, in
+#   the default configuration, apache2 needs to be started/stopped with
+#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
+#   work with the default configuration.
+
+
+# Global configuration
+#
+
+#
+# ServerRoot: The top of the directory tree under which the server's
+# configuration, error, and log files are kept.
+#
+# NOTE!  If you intend to place this on an NFS (or otherwise network)
+# mounted filesystem then please read the Mutex documentation (available
+# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
+# you will save yourself a lot of trouble.

+# identification number when it starts.
+# This needs to be set in /etc/apache2/envvars
+#
+PidFile ${APACHE_PID_FILE}
+
+#
+# Timeout: The number of seconds before receives and sends time out.
+#
+Timeout 300
+
+#
+# KeepAlive: Whether or not to allow persistent connections (more than
+# one request per connection). Set to "Off" to deactivate.
+#
+KeepAlive On

+#
+# MaxKeepAliveRequests: The maximum number of requests to allow

+# HostnameLookups: Log the names of clients or just their IP addresses
+# e.g., www.apache.org (on) or 204.62.129.132 (off).
+# The default is off because it'd be overall better for the net if people
+# had to knowingly turn this feature on, since enabling it means that
+# each client request will result in AT LEAST one lookup request to the
+# nameserver.
+#
+HostnameLookups Off
+
+# ErrorLog: The location of the error log file.
+# If you do not specify an ErrorLog directive within a <VirtualHost>
+# container, error messages relating to that virtual host will be
+# logged here.  If you *do* define an error logfile for a <VirtualHost>
