A spoofed email is an email that appears to be from a legitimate sender, but is actually from an unauthorized sender. Spoofing emails are often used in phishing attacks, which are attempts to trick recipients into clicking on malicious links or opening malicious attachments.
Spoofing emails work by forging the sender’s email address. This can be done by changing the “From” field in the email header. The recipient’s email client will then display the spoofed sender’s address, which may look like a legitimate email address.
How Does Spoofing Work?
Spoofing emails work by forging the sender’s email address. This can be done by changing the “From” field in the email header. The recipient’s email client will then display the spoofed sender’s address, which may look like a legitimate email address.
There are a few ways that spoofing can be done:
- Simple spoofing: This is the most basic form of spoofing. The attacker simply changes the “From” field in the email header to a legitimate email address. This can be done by using a tool like MailSniffer or by manually editing the email header.
- Domain spoofing: This is a more sophisticated form of spoofing. The attacker registers a domain name that is similar to the domain name of a legitimate sender. For example, the attacker might register the domain name “gmail.com.fake”. They would then send emails from this domain, which would appear to come from Gmail.
- IP spoofing: This is the most advanced form of spoofing. The attacker sends the email from an IP address that is spoofed to look like the IP address of a legitimate sender. This can be done by using a tool like ettercap or by manually editing the IP header of the email.
Once the spoofed email has been sent, it will appear in the recipient’s inbox as if it came from the legitimate sender. The recipient may be tricked into clicking on a malicious link or opening a malicious attachment, which could lead to malware infection or identity theft.
There are a few things that can be done to protect against spoofing emails:
- Be aware of the signs of a spoofed email. Some common signs of a spoofed email include:
- The email address in the “From” field does not match the domain name of the website that the email claims to be from.
- The email has poor grammar or spelling.
- The email contains a sense of urgency, such as “Click here now!” or “Your account has been compromised!”
- Do not click on links or open attachments in emails from unknown senders. If you are unsure whether an email is legitimate, you can hover over the link to see the actual URL. You can also scan the attachment with antivirus software before opening it.
- Use a spam filter. A spam filter can help to block spoofed emails from reaching your inbox.
By being aware of the signs of a spoofed email and taking precautions, you can help to keep your computer and personal information safe.
