Have an iPad that a client has brought in believes the devices has been compromised by a remote scammer. He believed he was talking with Amazon customer support until they claimed to have over credited his account by $500 and required him to go to town and get $500 worth of Target gift cards. Obviously this was a scam. He googled the phone number for Amazon, and the person had an Indian accent. That person was allowed to remote into the iPad mini, but cannot confirm if he was able to make changes or only view things. He has closed the CC accounts (He gave them the full CC # and last 4 of his social security), and contacted Social Security administration (He is retired and collecting from SS). But what we have never had to deal with is an IOS device used in a scam. What apps or process should be used to clean and verify the tablet?
