Last night a few users began reporting that their Apple IDs had been compromised, causing them to be locked out of their accounts. Recovering and password resets worked for a handful of Apple IDs, but it was still unclear overnight what might have been happening to cause the small breach in Apple's otherwise secure universal log-in system.
This morning speculation came to a close as third-party email client Spark confirmed that an upgrade to faster servers for iCloud users on the platform triggered the issue and forced password resets in a collection of Apple IDs. The company mentioned that it has been preparing to launch Spark for Mac, which was the reason for the faster server upgrade, but now promises that "there's NO breach or data leak" that users have to worry about.
Readdle, the creators of Spark, reiterated what it tweeted out throughout the morning in a post on Reddit.
Hello guys,
Thank you for the feedback and comments! Our team has been investigating this for a few hours. What we know so far: 1. There's no breach or data leak according to our investigation. 2. The new, faster AWS server logic might have triggered iCloud security algos. We are already working with Apple to learn more details. We are doing some server side work to make Spark much faster, and to make it ready for the Mac version, which is already in Alpha. We will keep you updated once we have more news from Apple side.
Thank you.
As some users have noted, the security problem didn't hit all Spark users who use the service with their iCloud account. The company said that it's working with Apple to get the issue fixed as soon as possible, but it seems that users affected by the security lockouts need not worry about malicious attempts at entry into their private Apple ID at least. If Readdle posts any more updates on its fix for the problem, we'll update this story as well.

The safety and security of your information also depends on you. You should not share your email user name and password with anyone. If you find out that anyone has improperly obtained your login credentials and accesses your email account through Spark, you should immediately change your password. We are not responsible for such unauthorized access unless the access is our fault."

LOL. What a con. Apple should punt this app from the App Store.
With 2 factor authentication on iCloud, there should be no way Spark could permanently hack your iCloud account since you have to generate a one time password for it. But I still don't like that it locks accounts. Maybe after everything is fixed I'll give it another try.
* Since they are impersonating you, they need to keep your password stored, not a one-way hash of it. How securely are they storing it? Who has access to it at the company?
* How secure is the email storage on their servers? Do they have one giant database serving all users, and filter by ID, or separate, segregated databases for each user?
* Can technical problems at their end cause emails to be deleted unintentionally?
Email is far too important to me to introduce layers of complexity and uncertainty like that.
