Oh, we didn't say they solved the issue.. here it is mainly 'Do you want
to buy a list of users' spam..
But percentage wise, we are seeing a lot less than say a couple weeks ago..
Again, what you are seeing, or what we are seeing.. pretty easy to
stop.. at the source.

Really? I'm seeing a constant stream of fake dating spam from apparently
compromised O365 accounts, with no end in sight.
Many of them use link shorteners (mostly tinyurl.com), content text has
so little variation that good old regex rules get all of them, so it
seems to be just a single spamming operation. Targets are german, so
that may be a reason you're not seeing those.
Looks like either password databases have been leaked somehow (although
I consider that very unlikely) or the tenants get to implement their own
password policies (which seem to be mostly "anything goes") so that
newly created accounts get fixed or easily guessable passwords. I've yet
to read another plausible explanation for this wide-spread compromising.
Cheers,
Hans-Martin
