Hi all,since a couple of days, I'm seeing an influx of spam mails sent via Zendesk tickets.
The spammers open fraudulent tickets at companies using Zendesk and either spoof the headers or enter random (e.g. mine and from a couple of others I talked to) mail address as contact address.
They seemingly had this issue in the past, and somehow resolved it, but even though I sent a mail to security@ two days ago, the influx of spam mails _increased_.
I have DKIM, SPF and DMARC in place, so either their check is broken and accepts spoofed headers or there is something else going on.
Has anyone on-list seen the same issue or even better a direct contact I could forward my 50+ samples to?
Thanks! All the best Lothar
