Finished keylogger in C#
by Arxleol on Sunday 01.11.2009, under C#, hack, tutorial, windows
OK we have finally reached till the end of road on how to write keylogger in c#. Here are all classes you require and all previous tutorials merged together. Some things were not explained because I think that it is common knowledge or will be explained in some future tutorials.Hook for hooking to keyboard and listening for keys. Hook.cs

And for running all this you should use Program.cs
using System; using System.Collections.Generic; using System.Linq; using System.Windows.Forms; namespace KeyHookSucks { static class Program { /// /// The main entry point for the application. /// [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } } }

I guess that there is something wrong because project works. So either I copied content wrongly, or you haven’t created objects correctly.

hi
in form1.cs give an error for:
if (secretWord.CompareTo(“”)==0)
this is error:
Object reference not set to an instance of an object.

The code is clean and almost perfect. Most of the errors are related to html entities such as “greater than” and “AND”.
The following error
if (secretWord.CompareTo(“”)==0)
Is related to the file path secret.krs
You have three options
1) to create the files manually and asign the correct path for example (@”C:\secret.krs”)
2) use if does not exist, create the file
3) Use the resources and serialization meaning the files are including during the build up.
Note you have to change the paths of all the files.
I will customise the code so the application can send the log file via ftp and also I will get rid of the user interface and make it hidden.
Thanks for this wonderful code. This tutorial made me understand how the keylogger work. I am advanced php web programmer in LAMP. I sometimes use C# for windows Asp.net and windows forms.

Thanks for the post if you intend to publish changes to the program make sure to provide backlink
Another idea I had but never had time to implement was screen capture might prove useful when people are over protective and use on screen keyboard.

Key Logger Spyware is substantially more damaging than many individuals believe. It is a great way of taking identities for vicious attackers which could leave you in significant debt which could be avoided definitely with Spyware Removal Tools

Errors out everytime i compile it X.x

My knowledge is also very limited in C# and I only figured how to do this with the source provided on msdnaa blogs. Because in fact I needed it. However, learning from example is also very useful.
Sunday 30.05.2010 on 10:41
I have extended the keylogger app & will post an article in the next few days.
Wednesday 02.06.2010 on 01:17
Thanks a lot man for this Code , “R.E.S.P.E.C.T” !
it compiles perfectly , just a question , I had try to add Filestream in place of Stream
public void writeToFile(String writing)
{
FileStream f = new FileStream(“logs.krs”, FileMode.Append);
TextReader tr = new StreamReader(“logs.krs”);
// read a line of text
String secr = tr.ReadToEnd();
// close the stream
tr.Close();
// create a writer and open the file
StreamWriter s = new StreamWriter(f);
// write a line of text to the file
s.Write(secr+writing);
s.Close();
// close the stream
f.Close();
}
my goal is to make logs.krs generation automatic ,
When I execute the exe it generate the log and after that it BUG’s ,
Any proposition please ??
after that I’ll work to send the log when size == 100000
the fonction of mailing I had done it fine , but the comparation and sender not yet
Any way , thanks for the verrrryyy educational source

When will you publish the project!!!
Wednesday 09.06.2010 on 20:15
Project is published and there is recent post about extended keylogger.

Hey Guys!
According to the HTML syntax some characters have to be masked. It seems to me, like this has happened here automatically. In order to refloat the project you simply to change three things:
Search for the characters an replace them in each file. Do not copy the quotation marks!
“>” means greater than. change each to “>”
“<” means lower than. change each to “<"
"&" is the "and". change each to "&"
Make sure you have created a "Windows Application"!
Now it'll work, have fun!
