Two days ago, we told you about an attack on jailbroken iPhones that compromised the accounts of some 220,000 iCloud users. New details have since emerged about the breach, that confirm what we initially speculated in the post on Tuesday evening.

The vast majority, if not all of the accounts, were of Chinese origin. On Wednesday morning, I personally confirmed this with someone directly in the know about the attack.

To that extent, a website has been created for potential victims of the attack to see if their account was compromised. That website is in Chinese, further emphasizing the origin and the region that was affected by this recent breach.

In all, there are a whopping 105,275 valid iCloud accounts out of the 220,000 compromised. That means that nearly half of those accounts captured contain active username and password combinations.

As speculated, this was indeed the result of a jailbreak tweak, but it was also self-inflicted, meaning users installed both the repo and the tweak responsible for the intrusion.
