iPhone 6s notification of being hacked
My sisters phone has recently come up with a notification claiming she has been surfing malicious websites , when she clearly hasn’t as she is young and uses her phone for innocent use and phonecalls etc… it has come up in her calendar that she’s been hacked and her phone will lock in 18 hours , with a link, haven’t clicked the link as I feel suspicious. I think it’s fake , but would rather be sure. Thank you!
