I just discovered 15 email messages in my Sent mailbox that I didn't send. Each message is addressed to 3 different contacts from my Address Book, and each is a spammy 'make money online' type of message with a link. Each one is different but they were all sent on the same date (May 18). I have an iMac with Mac OS X Lion 10.7.4 (11E53), and am using an firstname.lastname@example.org email address with an iCloud mailbox that syncs to my iPhone 4S. There haven't been anymore mystery messages since May 18th.
Does this sound like a worm or is it more likely that my me.com email account has been hacked?
Any advice on what I can do to prevent this from happening again?
I appreciate any advice/suggestions you can share.
To Rebuild just use Mail's Menu>Mailbox>Rebuild at the bottom.
I don't think you need Sophos at all, & I do think that is where/why those 15 messages went out, haven't found out how it works yet butperhaps this could prevent it, not sure though...
Little Snitch, stops/alerts outgoing stuff...
