Email header spoofing
Email header spoofing is when someone changes the sender's address in an email to trick you into thinking it's from a trusted source.
Email header spoofing is when a hacker alters the sender's information in an email to make it appear as though the message came from a different person or organization. This is done by modifying parts of the email header, which is the technical information that travels with an email. The goal is to deceive the recipient into believing the email is legitimate, often to steal sensitive information or spread malware.
Why it matters is that spoofed emails can be used in phishing attacks, where the attacker pretends to be a bank, colleague, or service provider to trick you into revealing passwords or clicking on harmful links. A common example is an email that looks like it's from your bank, asking you to click a link to "verify your account," which actually leads to a fake login page.
To deal with email header spoofing, use email security tools like mailcheck to verify the authenticity of incoming emails. Also, always check the sender's email address carefully, look for signs of urgency or requests for personal information, and avoid clicking on links in suspicious emails.
