Key-loggers are a serious security threat that can be extremely harmful

to both businesses and consumers. Current mechanisms do not provide

adequate protection to the user from these threats. We discuss a solution

that helps users mitigate the key-logging threat and show how CFA Defender®

can prevent the information leakage to current as well as future key-loggers.

Though PC users are worried about spyware that tracks web site visits, and

crashes their PCs, there are more insidious threats out there. A more powerful

breed of spyware can log keystrokes ( including passwords and credit card numbers)

and send that information to criminals. This type of software is called key-loggers.

A key-logger is a type of surveillance software that has the capability to record

every keystroke you make to a log file (usually encrypted). A key-logger recorder

can record instant messages, e-mail, and any information you type at any time

using your keyboard. The log file created by the key-logger can then be sent to

a specified receiver.

Some key-logger programs will also record any email addresses you use and

Website URLs you visit. This danger was recently highlighted when Sumitomo

Mitsui Banking Corporation discovered a Key-logger installed on its network

in London. There have been other high-profile cases.

Key-logging software was discovered at more than 14 Kinko locations in

New York. The perpetrator installed the software and using it to open bank

accounts with the names of some of the 450 users whose personal information

he collected. Valve Software founder Gabe Newell found the source code to

his company's Half-Life 2 game stolen after someone planted a key-logger

on his computer.

In 2013 the New York Times discovered a key-logger virus collecting data on

their reporters confidential sources. Key-logging is a serious security threat

that can be extremely harmful to both businesses and consumers.

By copying keystrokes, hackers are able to access private financial information such as

bank accounts, credit card numbers, and social security numbers–all of which can be

used for fraudulent activities, that you won’t know are occurring until the effects

show up on a statement, bill or via a phone call which could take days, weeks or

months to surface.

How key-loggers work.. Key-loggers work by hooking the Windows message queue.

It is relatively easy to place a global hook and inspect all the windows messages

(such as keystroke messages) before they are sent to the application.

The key-loggers then log the keystroke messages into a file.

Typically, the key-logger communicates with the hacker via an IRC channel

and delivers the captured keystroke file to the hacker. Many key-loggers also

incorporate stealth mechanisms (using root kit techniques) to hide their existence

so that they cannot be detected by anti-virus software.

Why current tools don’t work All anti-spam and anti-virus tools are based on

scanning a computer for files with a particular signature. The database containing

signatures of known bad files have to be  continuously updated. The major cave

at in this approach is the existence of the signature of a known problematic file.

Spammers and Criminals are currently deploying sophisticated software which

dinamically changes the file signature. Therefore, anti- spam tools are no longer

effective against key-loggers. Also, there is significant time between detecting

a new key-logger on the internet and the anti-key-logging signature being

updated on anti-virus/spyware software.

This time gap can a month to a couple of months. Some of the anti-key-logging

software prevents Windows hooks from being used by key-loggers (Windows

hooks are used by key-loggers to spy on keystrokes sent from the keyboard

to the application ). However, there are not always effective and can be

circumvented by key-loggers in most cases.

How key-loggers are inserted into a computer A key-logger can be inserted

into a victim’s computer via several ways. It can be carried by a virus or spyware.

It can come as an attachment in an e-mail. For example, the Corporate IT Forum ( Tif )

spam email contains a website link, the clicking of which, causes a key-logger

to be loaded into the computer. It can even be embedded in an mp3 file or

delivered via a XSS (Cross Site Scripting) attack.

How does CFA DEFENDER® protects users;

CFA Defender® uses a different approach to defend against key-loggers. Rather

than trying to detect key-loggers, it takes a preventive approach. It takes control

of the keyboard at the lowest possible layer in the kernel. The keystrokes are

the encrypted and sent to the browser via an “ Out-of-Band” channel bypassing

the Windows messaging queue.

Our System has a built in inself monitoring capability. This prevents it from

being bypassed by other software. If our software is tampered with in any

way, it will warn the user of the breach.
