Over 250,000 IPs look like candidates ..

That subdomain style, I've been eyeballing that trend for a while. This guy got super mad at me for identifying that trend on a network that hadn't yet started sending spam: https://forum.directadmin.com/threads/rbl_dns_list-suggestion.64780/post-350740

But you see the trend here: https://bgp.he.net/net/5.183.96.0/22#_dns

Ex:

5.183.97.2    pwit.castlerockcompany.org.uk
5.183.97.3    ctran.expeditiondevelopment.org.uk
5.183.97.4    fscanf.acadiainternational.org.uk
5.183.97.5    souvi.acadiainternational.org.uk
5.183.97.6    ahmal.acadiainternational.org.uk

And you see at one of the web pages, this same page gets around a lot on domains that look like those: http://castlerockcompany.org.uk

I wonder if this is a bunch of different actors sharing tools and methods, or if it's a single string running through a metric fuck ton of networks.

Normally, we could simply post this on a blog, but the traffic is
significant enough that other mail operators might be interested..

Last couple of days a LOT of new IP Address abuse from the same actors
using throwaway domains, on the typical suspect hosting providers, but
the sheer volume should be noticible.

Of course, this actor is pretty spammy in nature, and decent filtering
should be catching it anyways, but it is worth noting his methods
given the sheer volume.

(If you wonder about why networks gain bad reputations, most of the
names above are well known to anyone in the threat detection space)

Taking a look at some of the spam does reveal interesting information..

MAIL FROM Style: <el3c0odk...@znane.reticularia.com>
No Trace Headers
DKIM/Domain-Key Signatures (of course, spammers all do that now)

Subject: - An iPhone 14 Pro Max For You -

Typical Snowshoe spamming, old techniques.. Affiliate marketing? Or
malware distribution..

URL Links using dynserv.org.. 302's to known risky hosers, eg..

XonServers/Serverius/MNT-PINSUPPORT

Hosts a single script which uses.. https://www.blank.com/?a=47286

Which ultimately reaches.. wait for it.. boxmode.io again..

However, looking at the headers, and while they 'could' be forged, or
the person's server could be 'hacked', it is an indicator that this
may be a 'proxy' mail attack, and if they were sloppy, from a GoDaddy
server.

host static-ip-69-64-61-29.inaddr.ip-pool.com

(Good that GoDaddy does put up 'rwhois'.. it's the right thing to do)

69.64.61.29, OrgAbuseEmail:  i...@fsend4.com

(Let you play with that, a GoDaddy could confirm traffic behaviors)

You can play with the actual sites located at those IPs..

Simple way to see that they are all related.. (Submit your
Application, port 25/53/80/443)

This has all the hallmarks of setting up SMTP proxies..
