What is email spoofing?
Email spoofing is a cyberattack technique used to falsify the sender of an email by modifying its address to make it appear to be from a trusted source. Cybercriminals then change the email header to make the message appear genuine, attempting to trick recipients into opening the email, downloading malicious files, or sharing sensitive information.
This is a very worrying problem, as it can be carried out with great ease and has great potential to cause significant damage. It is a technique that can lead to various forms of fraud . An example is phishing , where cybercriminals pretend to be financial institutions, in order to steal personal or financial information. It can also be used to distribute malware or to carry out targeted attacks against a specific organisation.
