Security and privacy are key challenges for every computer user. While various security mechanisms, such as anti-virus, anti-spyware, updates and patches, are extensively applied, they cannot provide total security. Software keyloggers represent a fast-growing class of malware. Keylogging software records the user's typed keystrokes and saves them to a log file, and is therefore capable of logging sensitive information such as passwords, usernames, PINs and so on.1 It can also record user activities such as online chat, capture screenshots, note URLs visited and more. Moreover, some keyloggers can upload the log file directly to attackers through remote connections.2
