How Keyloggers Work

Keyloggers play the same role, although they are spread in different ways. Furthermore, Keyloggers record all the information you enter into your device and convey the same to the recipients.

Below, we highlighted a few examples that will help you understand how keyloggers work:

Social engineering

Phishing is to trick victims into divulging confidential information, a form of social engineering. Furthermore, cybercriminals pretend to be trusted contacts to convince recipients to download malware or open an attachment.

Downloaded software that cannot be identified.

Internet users can embed keyloggers in software they download from the internet. Unknowingly, whenever you download software, you also download keylogging software.
