https://virustotal.com/domain/media.rockstargames.com/information I did a scan for this domain this after visiting Steam's offical GTA V group and scanning an URL of one of the group's offical news message's image, and somehow it appears to be connected to (downloaded file analysis) couple of years old .exe.htm file that users claim to be malicious:

However, point is that where as it gave me http version when I copied the image's link from the Steam client itself, as when I visited GTA V Steam group on mobile Firefox, it showed the copied link of the image as https. Just copy the original scanned link into VT but switch http to https and you'll probably get the same result as I did where it shows the result being completely clean image file without any downloads with alerts.
