events of the keyboard and save into log file, therefore, it is able to
intercept sensitive information such as usernames, PINs, and passwords, thus
transmits into malicious attacker without attracting the attention of users. Using
this approach, an attacker can obtain valuable data without cracking into a
hardened database or file server. Keylogging presents a special challenge to

keyloggers are all but impossible to detect.
