Spotting Fake Phishing Emails

Red FAKE stamp and title Spotting Fake Phishing Emails from ezraharris.com over a blurred scam email screenshot

Yesterday I checked my Gmail spam folder, and I saw this email:

Email inbox row from sender info with the subject line You have an outstanding payment, beside checkbox, star and tag icons

Screenshot of the email header

The contents of the email are a general threat of a typical phishing email with the following:

It threatened to lock your various email accounts and asked for $950 sent to a BTC wallet. This is a pretty obvious scam in many ways, including that I have no actual email client setup, just a forwarding address. One interesting thing is that Gmail showed that it came from my email address.

Email header details: sent from and to info@stonesoftheearth.com, Jan 20, 2023, subject You have an outstanding payment.

(in this case, [email protected]). I wanted to see if it's easy enough to tell how it was spoofed. One way of doing this is viewing the original message, an unprocessed backend version of the email, including the email server logs, when Gmail receives it.

Using that, you can check whether or not the email was spoofed, aka an email coming from an email address but making it look like it's from your email. You can find out if it's spoofed or not usually by checking this line in the original message; you can see mine here:

Email header showing SPF softfail: stonesoftheearth.com does not designate 27.5.210.91 as a permitted sender

Showing that the original IP does not certify the email because it isn't allowed. I'm pretty sure Gmail checks for that line and sees if it's a legitimate email, then throws it into spam if it gives a soft fail. And if you grab the IP location, its somewhere in India:

IP lookup result with map pin near Sholinganallur, Chennai, showing ISP Hathway, Tamil Nadu, India, area code 600002.

IP details of email

In general, you never want to click on any links or follow any instructions given by an email that looks suspicious; make sure you check the message by googling it first; I found many forum posts saying they got the same copy-paste email as I got, just a different email.

And also, check that it's not spoofed, as I mentioned before, or a lookalike email, for example:

From: [email protected]

faking the email with minor changes, it seems like it's from [email protected].

One more thing I found interesting is that in the original message, the email said it was from [email protected] but right after said: "Using Preegsr tmraipj" not sure what that means, and I can't find any client called that; I'm guessing its a name, but it's clumsy for someone to leave that in the "from" section.
