How secure is iCloud mail?

I got the same spam and just deleted it.

Your email name (like mine) was "guessed" by the software used to generate the mass mailing.

Same here. Raspberry Ultradrops.

All my iCloud emails received it. I think it's unlikely that all my addresses were guessed.

Everything in the header is spoofed - to, from, reply... all meaningless:

It's the only spam my iCloud email has received to date. Whatever... spam is just an unavoidable fact of life.

I've had some of those Raspberry Ultradrops emails too, but from different addresses and to aliases as well as my main .mac/.me address, and to my late sister's .mac/.me inbox (which I've had to keep open and migrate to iCloud as there are sometimes legitimate messages to a voluntary group she was involved in).

I've also picked up a LOT of emails this last week or so saying I'm 'on the top' on Youtube, again to all the same addresses. These arel obviously spam as I haven't posted any videos on Youtube!

Spammers could have got my addresses from Yahoo Groups but my sister was never subscribed to Yahoo so that makes me concerned that there could have been a compromise with Apple's iCloud security.

Spam #2:

Whatever the reason, I have no doubt Apple will use this experience to improve their iCloud server - side spam protection. The disease must be observed before a cure can be found.

I've had the DrOz ones as well, and was just deleting at first, but may as well send to spam@me.com.

I've never used my icloud or me.com addresses, not the ones that are getting the spam... so I'm calling security breach.. "undisclosed@icloud.com" does tend to suggest that many many many people are getting this rubbish. Apple needs to clean up, and trap this stuff.

Add me to the list. I have had my .me and dot mac email addresses for as long as I can remember, I have kept it strictly as a personal email address and treated it with the utmost care. Since I switched to icloud it now gets spammed by Dr Oz. So does my wife's and she has had and never used her .mac address.

I don't know how this has happened, but I assume those who say it's been a breach at Apple are likely to be correct. Those who assert, assertively, that it is not an Apple failure and that my email and everyone else's were guessed - I'd like to see the evidence to support that assertion please.

There does seem to be a worrisome problem with the iCloud mail system at present. See this thread:

My husband and I have been receiving these spam emails. At first I just deleted them, then later began marking them as junk. They are from Christine Meyer, Dr.OZ and Dr.Oz Diet. These spam emails are coming to 3 of my me.com addresses, 2 of these addresses have never been used. Two are alias, but the other is my main iCloud address. I can delete an alias, but not my main icloud address.

I hope that Apple is reading our Spam problem and will address it soon. I've never had spam with my Apple mail until this started.

what a pain to be forced to delete aliases though.

How's everyone else going? Since junking and reporting the spam I've had... I have had no more. Its been ~24 hours now. Perhaps the spammers are taking a break, or perhaps Apple has put something specific in place now so many of us have reported this particular campaign.
