Keyloggers are a small program secretly installed by hackers on users' computers - usually after an attack that allows hackers to control the computer through an operating system security hole or process. Web browsing - aims to record every keyboard operation then send it to hackers.
This year, hackers distributed a total of 6,191 different keyloggers - an increase of 65% compared to the 3,753 of 2004. While that number was only 300 in 2000.
'There has been a strong explosion in integrating keylogger scripts into the most dangerous applications of spyware or phishing e-mails,' Dunham, iDefense's senior engineer said.
The main cause of the powerful explosion of keyloggers is the fact that the keylogger serves to make money for its owner. Once activated, it can record all personal information such as account numbers or login information to a corporate computer network to steal confidential information.
Keylogger does not exist in a completely independent way but is part of a new wave of crime. 'Rootkits are also becoming part of the keylogger technology. Trojans spoof various files to bypass dangerous software-killing applications. Keylogger, ad spyware and rootkits are getting closer. '
The number of keyloggers also means damage caused by increasing numbers. In the past year, keylogger-related criminal activities have caused a loss of about $ 382 million globally due to the theft of personal information such as login-password names, phone numbers, account number….
This proves the danger of keyloggers simply because of their 'quality of operation'.Users cannot stop doing things without knowing it.Everyone knows about viruses or worms but the real threat comes from what they don't know they're infected by a keylogger.
