Malware using camera on iPhone 6sPlus?

I keep getting texts that I visited a site that installed malware on my iPhone that let a person download all my information and access my to take Incriminating videos of me, and now they’re asking for payment to delete it. I have received several of these over the past couple of days and at first I was like SPAM but the more I get the more paranoid I get. My device is not jail broken so I think I’m safe, but can someone help a girl out and reassure me that the probability of this happening is very slim?
