The subjects seem to vary; but appear to involve animals, sex and cute
women in various orders (apologies to anyone offended by that).
Content is a one-liner link to porn sites.
I agree with the RIPE DB scrape - the From: line on one of these is
From: "Registry ripenotify" <info@audiovisualcs.com>
and the CC line contains our notify: E-mail (plus a load more of this
junk to noc|peering|named contacts).
These seem to be botted machines sending mails 'legitimately' ie:
headers appear to show that the first hop was relayed out through a
normal route rather than just port 25 spray. Some are even kindly
pre-marked as spam.
We've had >250 turn up since 23:34 UTC yesterday (12 April). Appears to
have slowed/stopped around 05:00 UTC today (13 April).
Paul.
