Have you ever been the target of an email spoofer? This can be a difficult question to answer, especially if you don’t know what you’re looking for. Email spoofing can appear to be from legitimate sources, but the most important indicator is if the message looks like spam or fishy in general. If you ever receive a message like this, you might wonder why your spam filter didn’t catch such an obvious trap.
Email spoofing is when a hacker sends you a message that’s disguised as someone else, particularly someone you know or are associated with. This doesn’t necessarily mean that your contact has been hacked (though it could be possible), but it’s still a problem on your end. It’s up to you to identify and delete messages before you inevitably fall for one of these phishing scams. The only way to eliminate the threat of hackers is to take them seriously, and approach scams in an educated and informed manner.
How Email Spoofing Works
Email spoofing is a simple process that sounds like a lot of work, but the reality is that anyone with the proper tools can pull it off. All a spoofer needs is access to what’s called a Simple Mail Transfer Protocol (SMTP) server, and an email software. SMTP servers are fairly simple to find for free, which makes it easy to spoof names. The one on the receiving end will still see the true email address, but it will appear to be from the address or name that the spoofer enters.
Despite how easy it is to attempt an email spoofing campaign, there are still plenty of checks available that make it more challenging to pull off these days. The most notable check is called Sender Policy Framework (SPF), which takes the IP address of the sending server and then compares it to the SPF record of the appropriate domain. If the two don’t match, the receiving server denies the message. The Huffington Post describes how this works using the following example:
Let’s say someone tried to spoof Bill Gates ([email protected]): They would send an email on his behalf > the recipient server would then talk back to microsoft.com and say “Hey, I have an email that is coming from 220.127.116.11 stating that it was sent from [email protected].”; > microsoft.com would then tell the recipient server, “No, sorry, it should be coming from 18.104.22.168.” and the message would never get delivered.
What You Can Do Against Spoofing
Email spoofing, while easy to pull off, often can’t make its way through modern email solutions like Gmail and Outlook. Even if it does make it through a spam filter, spoofed messages can still be somewhat tricky to identify at times. In particular, a spoofer who has researched their target, and who they’re posing as (i.e., “phishing”), can represent a significant risk. What you want to do is look at the email address that sent the message. If it’s different from the email address you have on file, you know it’s a spoofer.
Another obvious way to spot a spoofer is if they make absolutely no attempt to disguise themselves, or if they pose as an institution that you regularly attend. If the message holds any suspicious links or attachments, make sure that you don’t click on them. Chances are that you could be walking right into a phishing scam. If the message asks you to confirm your credentials, don’t do as they ask. Organizations like banks or government agencies will never ask you to confirm information through email. Never log into a website using the links provided in an email unless you’re absolutely positive it’s not a spoofer. Instead, try to navigate to the website through your web browser using their normal URL.
