Several of my contacts have received emails that appear to have come from me, but with an address that is obviously spam eg tbanks2709 <firstname.lastname@example.org>
What is more of a concern is that the spam content appears to have been added to an original genuine email from me, as though the email has been " Replied" to with the original content underneath.
That says to me that the original email was in someway intercepted. Given that I use secure links to the VM servers, that require a password for send and receive, how could this happen?
I have no reason to think my password has been hacked, and have changed it just in case. I run two different malware and virus scanners, both are showing no threats.
I would welcome some thoughts on how this situation has come about, and what else can be fine to stop it.
Intercepted… another possible explanation is that one (or more) recipient(s) maybe the source of the compromise?
