11816855855406387555” wants access to control “Safari.app

I keep getting this message: “11816855855406387555” wants access to control “Safari.app”. Allowing control will provide access to documents and data in “Safari.app”, and to perform actions within that app.

Is this something I should allow? I have recently been plagued with malware so I am cautious. I cannot find anything about this message.

Any ideas?
