Email header forgery
Email header forgery is a common technique used in phishing attacks to make fake emails look legitimate.
Email header forgery is when someone changes the information in an email's headers to make it appear as though the message came from a different sender. Headers include details like the sender's email address, the route the email took, and the domain it came from. Attackers can modify these to make a phishing email look like it came from a bank, a colleague, or another trusted source.
Why it matters is that it can trick people into revealing sensitive information or clicking on malicious links. For example, a scammer might forge an email header to make it look like a message from your bank asking for your login details.
To deal with email header forgery, use tools like mailcheck to verify the authenticity of incoming emails. Also, always check the sender's email address carefully, and look for signs like mismatched domains or unusual requests. Never respond to emails asking for personal or financial information unless you're certain they're genuine.
