An attacker is ready to trigger the goal’s iPhone, Apple Watch, or Mac to show system-level password change approval texts time and again, with the hope that the particular person being focused will mistakenly approve the request or get bored with the notifications and click on on the settle for button. If the request is accredited, the attacker is ready to change the Apple ID password and lock the Apple consumer out of their account.

When attackers are unable to get the particular person to click on “Permit” on the password change notification, targets usually get cellphone calls that appear to be coming from Apple. On these calls, the attacker claims to know that the sufferer is underneath assault, and makes an attempt to get the one-time password that’s despatched to a consumer’s cellphone quantity when making an attempt a password change.
In Patel’s case, the attacker was utilizing info leaked from a folks search web site, which included title, present tackle, previous tackle, and cellphone quantity, giving the particular person making an attempt to entry his account ample info to work from.
