For the record, this has been going on for some months now..
We have been even keeping track of the phone numbers used in this scam, but we already notice that they are attempting to obfuscate the phone numbers..

As Louis pointed out, it's the 'sellers note' that is being abused.. as well as the underlying invoice system itself, to change the destination email address for the invoice..

For those of you who have NOT yet seen one of these, including a snapshot as an attachment..

Aha!

That makes perfect sense - and I'm not sure how I overlooked that detail.

Much appreciated for clarifying that.

I too have had no luck getting PayPal to do anything about it, although I didn't point out the phishing part as I honestly hadn't noticed that.   I just looked at the headers to see if the email was legitimately from PayPal and not the content...  rookie mistake.

Thank you,

I've been getting these as well. They get DKIM signed messages and then resend them to another recipient. Could be automatic forwarding, but they could also be manually resending it. They do not alter the message, so DKIM passes. So, what's the deal, you ask?

Inside the "seller's note" is a text about contacting PayPal at some phone number if you don't recognize the transaction, which is where you'll get phished. As at that point you're calling the phisher.

So yes, it's phishing. No, DKIM isn't at fault here. If PayPal didn't allow user generated content in these emails, this issue would not exist. It's completely on PayPal side. I've already reported this instance to them on Thursday, but I remember many months ago we had the exact topic. PayPal must be aware, they're just not doing anything about it.


Groetjes,

    Are they modifying the message as a part of the relay to adjust
    the phone number?

    Isn’t DKIM supposed to prevent in-flight modification of emails?

    It looks like based upon the headers provided - the original
    message is dkim signed.

    Maybe it’s being stripped out when it’s relayed?

    Regardless - when we reached out to PayPal we couldn’t manage to
    get anyone to understand what was happening.  Microsoft has been
    even less helpful.
