Abstract: In an embodiment, a method comprises intercepting, from a first computer, a first set of instructions that define one or more original operations, which are configured to cause one or more requests to be sent if executed by a client computer; modifying the first set of instructions to produce a modified set of instructions, which are configured to cause a credential to be included in the one or more requests sent if executed by the client computer; rendering a second set of instructions comprising the modified set of instructions and one or more credential-morphing-instructions, wherein the one or more credential-morphing-instructions define one or more credential-morphing operations, which are configured to cause the client computer to update the credential over time if executed; sending the second set of instructions to a second computer.

Abstract: In an embodiment, a method comprises intercepting, from a server computer, a first set of instructions that define one or more objects and one or more operations that are based, at least in part, on the one or more objects; generating, in memory, one or more data structures that correspond to the one or more objects; performing the one or more operations on the one or more data structures; updating the one or more data structures, in response to performing the one or more operations, to produce one or more updated data structures; rendering a second set of instructions, which when executed by a remote client computer cause the remote client computer to generate the updated data structures in memory on the remote client computer, wherein the second set of instructions are different than the first set of instructions; sending the second set of instructions to the remote client computer.

Abstract: In an approach, an apparatus comprises: one or more processors; a processor logic coupled to the one or more processors and configured to: intercept, from a client computer, a request directed to a server computer that identifies a purported user agent executing on the client computer; send, to the server computer, the request from the client computer; intercept, from the server computer, one or more original instructions to be executed by the purported user agent of the client computer; determine one or more features supported by the purported user agent that are not utilized by the one or more original instructions; transform the one or more original instructions into one or more revised instructions which, when executed by the purported user agent, cause the purported user agent to utilize the one or more features; send, to the client computer, the one or more revised instructions.

Abstract: In an embodiment, a method comprises intercepting, from a server computer, a first set of instructions that define a user interface; executing, using a headless browser, the first set of instructions without presenting the user interface; rendering a second set of instructions, which when executed by a client application on a client computer, cause the client computer to present the user interface, wherein the second set of instructions are different than the first set of instructions; sending the second set of instructions to the client computer.

Abstract: In an embodiment, a computer system configured to: generate a first challenge credential to be sent to a client computer; render one or more first dynamic-credential instructions, which when executed by the client computer, cause the client computer to generate a first dynamic credential that corresponds to the first challenge credential; modify a first set of instructions, which define one or more original operations, to produce a second set of instructions, wherein the second set of instructions include the first challenge credential and the one or more first dynamic-credential instructions, and which when executed by the client computer, cause the first challenge credential to be included in the one or more requests sent from the client computer; send the second set of instructions to a second computer.

Abstract: In an embodiment, a method comprises intercepting a first set of instructions from a server computer that define one or more objects and one or more original operations that are based, at least in part, on the one or more objects; modifying the first set of instructions by adding one or more supervisor operations that are based, at least in part, on the one or more objects; transforming the one or more original operations to produce one or more transformed operations that are based, at least in part, on the one or more supervisor operations; rendering a second set of instructions which define the one or more supervisor operations and the one or more transformed operations; sending the second set of instructions to a remote client computer.
