What is Keylogger
A key stroke logger is a program that you can install on your computer that logs every keystroke that’s made on the system. This means that you can log people’s passwords etc. Anything that is typed on the computer get’s logged so that the administrator of the key stroke logging tool can login later to see what someone else typed. Be careful using KSLs. They are illegal in some states and it’s considered a federal offense if used illegally. I believe as long as the computer belongs to you and you’re just logging for security purposes then you’re ok, but you should definitely talk to a legal professional in your state before attempting to use one.
There’s alot of different keyloggers Heres some examples:
Hypervisor-based: The keylogger can theoretically reside in a malware hypervisor running underneath the operating system, which remains untouched. It effectively becomes a virtual machine. Blue Pill is a conceptual example.
Kernel-based: This method is difficult both to write and to combat. Such keyloggers reside at the kernel level and are thus difficult to detect, especially for user-mode applications. They are frequently implemented as rootkits that subvert the operating system kernel and gain unauthorizedaccess to the hardware, making them very powerful. A keylogger using this method can act as a keyboard device driver for example, and thus gainaccess to any information typed on the keyboard as it goes to the operating system.
API-based: These keyloggers hook keyboard APIs; the operating system then notifies the keylogger each time a key is pressed and the keylogger simply records it.
Form grabbing based: Form grabbing-based keyloggers log web form submissions by recording the web browsing on submit event functions.
Packet analyzers: This involves capturing network traffic associated with HTTP POST events to retrieve unencrypted passwords.
A keylogger is normally used for recording information such as credit card numbers, bank account numbers, passwords, and a bunch of other stuff
normally keyloggers are associated with viruses that send the passwords and things to some hacker somewhere. If you want to get rid of a keylogger, you absolutely need to remove keylog.
