Re: [mailop] Cloud hosts for responsible mail servers?

Hi Tony, Gone are the days when you could just throw a Linux box up in a colo and expect to get your mail delivered. You can easily become the unwitting victim of being in a bad IP neighborhood through no fault of your own. Although this advice is painful, I recommend using a service for final

Hi Slavko The UCEPROTECT list has a large bark, but very little bite. We have never seen serious problems relating to a listing on their service. It is, however, widely seen as having major significance by ISPs, particularly those located in Asia. I have no idea why this is the case. Regards Ken

Re: [mailop] Phishing and 2FA auth

Hi Slavko Not all 2FA approaches are equal. The most robust 2FA systems are ones in which both the service and the second-factor client robustly authenticate each other. Two-way authentication eliminates the possibility that someone can sit in the middle of the second-factor exchange to gain

PayPal is best positioned to solve this problem because it can police the logo images its customers upload. That being said, this type of platform abuse, while not entirely new, seems to be increasing. Please get in touch with me if you are interested in testing our computer vision API that

Re: [mailop] [EXTERNAL] Really good paypal phishing email this morning

Hi Michael, I've seen the raw email; it did come from PayPal. PayPal needs to get better at recognizing brand images so that this kind of impersonation is more difficult on their platform. No doubt they are already working on that. Ken On Fri, Nov 18, 2022 at 11:32 AM Michael Wise via mailop

Hi Jarland, Yes, we see this as well - since this morning Pacific Time. They are snow-shoeing too, sending just one or two submissions per web form, presumably to keep a low profile. Same pattern of recipients as you are seeing. I'm trying to track down the victim software, which seems to be a
