Keylogger

Understanding Keyloggers

A keylogger, also referred to as keystroke logging software, is a tool employed by hackers to record the keystrokes made by users. Hackers utilize keystroke logging software and hardware keyloggers to capture and access sensitive information of victims, such as bank details, account passwords, private keys, etc., for personal gain.

There are three primary types of hardware keyloggers:

1. Hidden camera loggers, which visually monitor keystrokes.
2. USB-loaded keyloggers that deliver malware containing a keystroke logger to a computer.
3. Keyboard hardware keyloggers that are either built-in or connected to a device via a cable.

Keyloggers can be used to steal digital currencies from users by recording their private keys from their crypto wallets or logging their exchange passwords. To mitigate this risk, it is recommended to use a hardware wallet and enable the two-factor authentication (2FA) feature in exchange accounts, which is supported by most major crypto exchanges.

While keyloggers are often associated with malicious activities, they also have legitimate use cases. For instance, system administrators may utilize keylogging software to track employees’ activities. Keyloggers are also valuable for law enforcement as they can monitor criminals and efficiently send all recorded information to relevant offices.

In the current landscape, keyloggers have evolved from being primarily used by criminals or governmental organizations to becoming a commercial market of their own, allowing individuals to purchase their own copy of keylogging software. A common and less malicious use case of keyloggers is parental control, where parents can monitor their children’s online activities.
