(CNN) — The passwords on iPhones can be hacked, giving someone the ability to make calls, listen to your recent messages and tinker with your contact list, according to a new video posted to YouTube.
The apparent security flaw is shown on an iPhone 5 and can be exploited on phones running Apple’s iOS 6.1, the most recent version of its mobile operating system, and some earlier versions.
The technique was posted by a Spanish-speaking user with the account name “videosdebarraquito,” who has posted other videos that show what appear to be ways to tweak settings on the iPhone. CNN is not linking to the video, which was published January 31 but recently discovered by tech bloggers.
It involves using another phone placed nearby to make a call to the phone, canceling it, then answering with the targeted phone and fiddling with the power button.
According to the user who posted the video, it can’t be used to access other parts of the phone. And he urged anyone who used it to play nice.
Use the bypass “to joke with your friends. To do a magic show. To win a harmless bet among friends in a PUB. Perhaps, to retrieve a phone number in case you don’t remember the password, or just to be warned that exists,” the user wrote.
“Use it as you want, at your own risk, but… please… use responsibly, do not use this trick to do evil !!!”
Apple did not immediately respond to a request for comment Thursday morning.
The folks at tech blog The Verge tried out the technique, and said they were also able to access photos on the phone by attempting to add a photo to a contact. They were able to access an iPhone 5 that was running iOS 6.1 in the UK, they said.
Similar bugs have been pointed out in previous versions of Apple’s mobile operating system. Usually, the company issues a quick update to fix the problem.
