Hackers Using iCloud's Find My iPhone Feature To Remotely Lock Macs, Demand Ransom Payments (macrumors.com)

AmiMoJo shares a report from Mac Rumors: Over the last day or two, several Mac users appear to have been locked out of their machines after hackers signed into their iCloud accounts and initiated a remote lock using Find My iPhone. With access to an iCloud user's username and password, Find My iPhone on iCloud.com can be used to "lock" a Mac with a passcode even with two-factor authentication turned on, and that's what's going on here. Affected users who have had their iCloud accounts hacked are receiving messages demanding money for the passcode to unlock a locked Mac device. The usernames and passwords of the iCloud accounts affected by this "hack" were likely found through various site data breaches and have not been acquired through a breach of Apple's servers. Impacted users likely used the same email addresses, account names, and passwords for multiple accounts, allowing people with malicious intent to figure out their iCloud details.

      No, it isn't. Because if my data is valuable to others I want to be able to delete it remotely to stop anyone else accessing it. Because my data is valuable to me I backed it up, so wiping one copy doesn't hurt me.

      But let's be honest, if my data were valuable enough that I need to be concerned about my laptop being stolen I wouldn't give a shit about paying for a mere laptop, even if it was a MacBook.

      Well, given you just lost your "2nd factor" for a lot of users, how do you envision implementing 2FA?

      You just lost your phone. You can't have 2FA use an SMS, an app, or any other thing that relies on the phone you just lost.

      And you can't rely on the user having more than one Apple device. Or a replacement phone (which would require the original phone in order to register another trusted device, for obvious reasons).

    iCloud is nice and all but suffers from security concerns. Such a powerful tool needs a stronger security implementation, and has to offer users the way to see when and where connections do come from. Gmail has been doing that for a long time, and Apple is still lagging behind.
