Keyloggers are tools that secretly monitor keyboard input to steal sensitive information like passwords or credit card numbers. There are software and hardware keyloggers. Software keyloggers can operate invisibly as kernel drivers or by intercepting API calls, while hardware keyloggers may include keyboard overlays or wireless sniffers. Keyloggers aim to protect the stolen data and avoid detection through techniques like hiding processes and filenames or requiring a password to access stored logs. Users can help prevent keylogging through measures such as enabling detailed task manager views, scanning for suspicious programs, and using alternative input methods when necessary.

 Software Based Key Logger
 Hardware Based Key Logger
Types

6. 
Hypervisor-based: As virtual Machine
e.g. Blue Pills
Kernel-based:difficult to write and detect
e.g. Device Driver
API-based: Easy to write and easy to kill
e.g. Getasynckeystate() function
Form grabbing based :log web form submissions by
recording the web browsing onsubmit event
functions before encryption
Software Based Key Logger

7.  Data is uploaded to a website, database or an FTP server.
 Data is periodically emailed to a pre-defined email address.
 Data is wirelessly transmitted by means of an attached
hardware system.
 The software enables a remote login to the local machine
from the Internet or the local network, for data logs stored on
the target machine to be accessed.
 Clipboard logging
 Screen Logging
Some Extra features

 Keyboard hardware
 Wireless keyboard sniffers:
 Keyboard overlays (Double Layered )
 Acoustic keyloggers(Mobile Kepad Tone )
 Optical surveillance(CC Camera,Spy camera)

(Spy Camera)

11. 
 It is Like a pendrive which is invisible on computer.
 Press hot key to make it visible.
 There are large no of report Files,just open and see the
Reports.
Hardware Keylogger
Report reading Process

12.  Hiding process on Task Manager.
 Giving False Name like
rundll32.exe,svchost.exe,winlogin.exe,IEEXPLORER.e
xe
Running Mutual Monitoring Process side by side.
Writing Driver which prevent it from killing.
Calling dll file using rundll32.exe
Keylogger uses Hot Key and password to protect
their Data.
e.g.
HotKey :- Shift+Alt+S
How Keyloggers protect
Itself from user?

13.  Use Anti-Spyware,Anti-Keylogger .e.g:- Spybot
 Enable “Image Path Name” of Task Manager On windows
 Check startup application , msconfig.exe
 Clear Browser’s cookies after using public Computer.
 Use Live CD while using other’s Computer.
 Use On-screen Keyboard while entering password.
 Use different Keyboard Layout.
 Use Smart Card .
Detection And Prevention

14. 
 Use Speech to Text Services.
 Use Hand writing recognition Tools.
 Type Password randomly
if Your password is a1b2c3d4
then first type 1234 & then click at first position enter a
similar click on other proper position and enter
corresponding
letter ,then Key logger logs seems to be
[click]a[click]b[click]c[click]d
