CEH Practical: Gathering Target Information: Reconnaissance And Competitive Intelligence
CEH Exam Objectives:
Describe Reconnaissance.
Describe aggressive/competitive intelligence.
Reconnaissance
Reconnaissance is the process of gathering informative data about a particular target of a malicious hack by exploring the targeted system. Basically two types of Reconnaissance exist i.e. Active and Passive. Active reconnaissance typically related to port scanning and observing the vulnerabilities about the targeted system (i.e., which ports are left vulnerable and/or if there are ways around the firewall and routers). Passive reconnaissance typically you will not be directly connected to a computer system. This process is used to gather essential information without ever interacting with the target systems.Understand Aggressive Intelligence
Competitive intelligence means information gathering about competitors' products, marketing, and technologies. Most competitive intelligence is non intrusive to the company being investigated and is benign in nature. It's used for product comparison or as a sales and marketing tactic to better understand how competitors are positioning their products or services.Online tools to gather competitive intelligence
Exercise 1.1
Using KeywordSpy
To use the KeywordSpy online tool to gather competitive intelligence information:- Go to the www.keywordspy.com website and enter the website address of the target in the search field
- Review the report and determine valuable keywords, links, or other information.
Exercise 1.2
Using spyfu
- Go to your browser and type www.spyfu.com and enter the website address of the target in the search field.
Exercise 1.3
Using the EDGAR Database to Gather Information
1. Determine the company's stock symbol using Google.
2. Open a web browser to www.sec.gov.
3. On the right side of the page, click the link EDGAR Filers.
2. Open a web browser to www.sec.gov.
3. On the right side of the page, click the link EDGAR Filers.
4. Click the Search For Filings menu and enter the company name or stock symbol to search the filings for information. You can learn, for example, where the company is registered and who reported the filing.
5. Use the Yahoo! yellow pages ( http://yp.yahoo.com ) to see if an address or phone number is listed for any of the employee names you have located.

Linux Command Line Hackery Series: Part 2
Welcome back to Linux Command Line Hackery, yes this is Part 2 and today we are going to learn some new skills. Let's rock
Let us first recap what we did in Part 1, if you are not sure what the following commands do then you should read Part 1.
mkdir myfiles # make a directory (folder) with myfiles as name
cd myfiles # navigate to myfiles folder
touch file1 file2 file3 # create three empty files file1, file2, file3
ls -l # view contents of current directory
echo This is file1 > file1 # write a line of text to file1
cat file1 # display contents of file1
echo This is another line in file1 >> file1 # append another line of text to file1
cat file1 # display the modified content of file1
Command: cp
Syntax: cp source1 [source2 ...] destination
Function: cp stands for copy. cp is used to copy a file from source to destination. Some important flags are mentioned below
Flags: -r copy directories recursively
-f if an existing destination file cannot be opened, remove it and try again
Let us make a copy of file1 using the new cp command:
cp file1 file1.bak
what this command is going to do is simply copy file1 to another file named file1.bak. You can name the destination file anything you want.
Say, you have to copy file1 to a different folder maybe to home directory how can we do that? well we can do that like this:
cp file /home/user/
I've used the absolute path here you can use whatever you like.
[Trick: ~ has a special meaning, it stands for logged in user's directory. You could have written previous command simply asNow you want to create a new directory in myfiles directory with the name backup and store all files of myfiles directory in the backup directory. Let's try it:
cp file1 ~/
and it would have done the same thing.]
mkdir backup
cp file1 file2 file3 backup/
this command will copy file1 file2 file3 to backup directory.
We can copy multiple files using cp by specifying the directory to which files must be copied at the end.
We can also copy whole directory and all files and sub-directories in a directory using cp. In order to make a backup copy of myfiles directory and all of it's contents we will type:
cd .. # navigate to previous directory
cp -r myfiles myfiles.bak # recursively copy all contents of myfiles directory to myfiles.bak directory
This command will copy myfiles directory to myfiles.bak directory including all files and sub-directories
Command: mv
Syntax: mv source1 [source2 ...] destination
Function: mv stands for move. It is used for moving files from one place to another (cut/paste in GUI) and also for renaming the files.
If we want to rename our file1 to file1.old in our myfiles folder we'll do the follow:
cd myfiles # navigate first to myfiles folder
mv file1 file1.old
this command will rename the file1 to file1.old (it really has got so old now). Now say we want to create a new file1 file in our myfiles folder and move the file1.old file to our backup folder:
mv file1.old backup/ # move (cut/paste) the file1.old file to backup directory
touch file1 # create a new file called file1
echo New file1 here > file1 # echo some content into file1
Command: rmdir
Syntax: rmdir directory_name
Function: rmdir stands for remove directory. It is used for removing empty directories.
Let's create an empty directory in our myfiles directory called 'garbage' and then remove it using rmdir:
mkdir garbage
rmdir garbage
Good practice keep it doing. (*_*)
But wait a second, I said empty directory! does it mean I cannot delete a directory which has contents in it (files and sub-directories) with rmdir? Yes!, you cannot do that with rmdir.
So how am I gonna do that, well keep reading...
Command: rm
Syntax: rm FILE...
Function: rm stands for remove. It is used to remove files and directories. Some of it's important flags are enlisted below.
Flags: -r remove directories and their contents recursively
-f ignore nonexistent files and arguments, never prompt
Now let's say we want to delete the file file1.old in backup folder. Here is how we will do that:
rm backup/file1.old # using relative path here
Boom! the file is gone. Keep in mind one thing when using rm "IT IS DESTRUCTIVE!". No I'm not yelling at you, I'm just warning you that when you use rm to delete a file it doesn't go to Trash (or Recycle Bin). Rather it is deleted and you cannot get it back (unless you use some special tools quickly). So don't try this at home. I'm just kidding but yes try it cautiously otherwise you are going to loose something important.
Did You said that we can delete directory as well with rm? Yes!, I did. You can delete a directory and all of it's contents with rm by just typing:
rm -r directory_name
Maybe we want to delete backup directory from our myfiles directory, just do this:
rm -r backup
And it is gone now.
Remember what I said about rm, use it with cautious and use rm -r more cautiously (believe me it costs a lot). -r flag will remove not just the files in directory it will also remove any sub-directories in that directory and there respective contents as well.
That is it for this article. I've said that I'll make each article short so that It can be learned quickly and remembered for longer time. I don't wanna bore you.

Voodoo-Kali - Kali Linux Desktop On Windows 10
How it works?
* Kali Linux with XFCE Desktop Environment in Windows Subsystem for Linux (WSL)
* VcXsrv X Server for Windows is doing the hard GUI lifting
* XFCE is started natively in WSL and displayed by VcXsrv
Install Voodoo-Kali:
1, Enable WSL and install Kali Linux from the Microsoft Store. Read Install Kali Linux desktop on Windows 10 from Microsoft Store
2, To start Kali Linux in Windows 10, open Command Prompt and enter the command: kali
3, Enter this commands:
apt install wget -y
wget https://raw.githubusercontent.com/Re4son/WSL-Kali-X/master/install-WSL-Kali-X
bash ./install-WSL-Kali-X
4, Download and install VcXsrv Windows X Server from SourceForge
5, Start VcXsrv, accept change in firewall rules, exit VcXsrv
Run Voodoo-Kali:
Start kali in Windows as normal user (that's default), and launch Voodoo-Kali:
* as normal user: ./start-xfce
* as root: sudo /root/xtart-xfce
Run Kali Desktop in an RDP session:
In Kali Linux WSL, type: sudo /etc/init.d/xrdp start
In Windows 10, open Run and enter mstsc.exe and connect to "127.0.0.1:3390"
Status: Voodoo-Kali is in its infancy and it is far from being elegant. I'm working on it though and step by step I'll push out improvements. Below a snippet of the To-Do list:
* Clean up and comment the scripts
* Make for a cleaner exit
* Better error handling and dependency checking (get rid of sleep, etc.)
* Improve stability of Java programs
* Improve the looks??
* …
Any help is truly appreciated, in any shape or form – from tips to pull requests.
Why don't you join the forums to discuss?

Web Hacking Video Series #4 MySQL Part 2 (Injection And Coding)
Video Lesson Topics:
Part 2 of Mysql covers the topic of injecting a simple SQL injection example. Starts out slow then combines techniques and moves into more advanced topics. Prior to attempting this lesson make sure you have watched the videos in the previous blog or understand both SQL and basic python coding. I will show how to automate the injection process via python utilizing simple HTML processing abilities of beautiful soup. I will cover many python libraries for encoding data and calling web based applications. I also talk about how to deal with encrypted data and methods of enumerating files and folders looking for possible implementation issues and attack points to decrypt sensitive data via PHP/Python interaction with whats available on the server. This is the 2nd part of a 3 part series on MySQL for attacking web applications.
