The website allows you to download an application, which will Apple Support to be able to view and record your screen as part of your support session but cannot access your files or control your computer. But, although ara.apple.com is legit, there are scammers who have created fake domain names looking similar to it.

If someone contacts you or you receive a message from someone claiming to be an Apple technical support representative, asking you to go to a website and download an application in order to help you, please do not follow the person's instructions. Remember, technical support does not call you, you call them. And, if the person claims he/she is actually from Apple, go directly to ara.apple.com, which is legit. And, never let the person tell you which website to go to because there is no way to tell if the caller is a scammer or not.
