receive a request, from a client device and intended for a server device, to provide a resource,
the resource being associated with information stored by the server device;
the client device executing a malicious script that performs one or more undesirable tasks directed to the server device,
the request being transmitted by the client device based on the client device executing the malicious script;

one or more other requests received from the client device,
a quantity of requests, received from the client device, within a particular amount of time, or
a score indicating a probability that the request is associated with the malicious script;
receive, from the server device, a response to the request,
the response including information associated with the resource;
