For my fellow exim users: https://github.com/mxroute/da_server_updates/commit/953e4f3f4384010dbd0691a776a166675f17f0ed

One more path closed for the phishing crew.

Sorry if I missed part of the discussion, but now they're circumventing the SRS headers and Microsoft is straight up spoofing PayPal envelope senders. First catch of this for me was today. Here's a look: https://mxbin.io/89sXAc

The logs showing the envelope sender quite clearly as well:

2024-12-13 19:22:25 1tMBF2-0000000F7eV-386r <= serv...@paypal.com H=mail-koreacentralazlp17013079.outbound.protection.outlook.com (SEYPR02CU001.outbound.protection.outlook.com) [40.93.138.79] P=esmtps X=TLS1.3:TLS_AES_256_GCM_SHA384:256 CV=no S=51168 DKIM=paypal.com id=CE.66.22381.7B87C576@ccg01mail10 T="You've got a money request" from <serv...@paypal.com> for jarl...@mxroute.com

Someone at Microsoft needs to get on this ASAP, and PayPal needs to have more faith in their SPF record and trade that soft fail. This is looking pretty bad. I'm considering this a friendly nudge to anyone watching this mailing list from both companies.

Ouch.. getting even harder for recipient spam protections to catch this guy, given that o365 is also a 'too big to block'..

Standard Paypal Phone Scam we have seen coming from PayPal's own infrastructure.. But now via o365.. redaccted headers below..

(PayPal should have stopped this at the source long ago)

Maybe someone from o365 can confirm this..

(Also, a duplicate Return-Path problem)
