is rumored to have said:
We're getting a crap-tonne of garbage mailings from 162.217.160.0 -
162.217.167.255 which is all Electronic Transaction Consultants
Corporation (etcc.com) now owned by Quarterhill - publicly traded on
the TSX.
Tens of thousands of messages per day, we've blocked the entire range.
Again, I will recommend using the Spamhaus DROP list.
https://check.spamhaus.org/faqs/do-not-route-or-peer-drop/
We're going to start publishing our email intelligence findings
starting with this one, it's just odd given the public nature of the
operator.
Anybody know anything about them in terms of their mailing practices?
I feel no need to investigate entities that reliable parties who do that
all the time have determined to be intentional bad actors.
(I have messaged their ARIN contact - if this is a network compromise,
it's basically everything)
Good luck with that...
