Recently I received email from a trusted correspondent and carried on a back-and-forth discussion only to discover that the correspondent had originally started the exchange via a Hotmail account (which supposedly is never used).
Clearly, the correspondent needed to be signed in to send and then receive responses to the e-correspondence and should have been able to tell the difference between the Gmail account (and its GUI) normally used and that of Hotmail.
Alternatively, since an exchange between me and the correspondent ostensibly went to the correspondent's Gmail account, something is even fishier, given that the address used was hotmail.com. When I checked under "Show original" the initial message came via hotmail.com and my response went to hotmail.com — all confirmed as legitimate by Gmail.
To my mind the correspondent's various devices (iMac/iPad/iPhone) must have been hacked and hijacked to disguise that.
I suggested that the correspondent (who is otherwise unsavvy in the ways and wiles of malware and such) go to the Apple store to have the problem investigated.
As I see it and have recommended, the correspondent's devices have been compromised, which means that any sensitive information (including financial info, passwords and such) may be open to being stolen and therefore all such info on all devices should be deleted — although it's likely too late to close the door.
What say the assembled gurus on FTM about this issue?
