Samsung patents system that swaps network code for apps
Samsung describes a method where a system checks if an app has a specific network manager when it starts. If it does, the system intercepts the app's network requests, changes them to fit a new format, and sends the results back to the app.
In the filing’s own words
A system and method using a user-layer network solution (ULNs), and may include: when a ULNs loader detects execution of an application program, checking whether a ULNs manager of the application program exists; when the ULNs manager of the application program exists based on a result of the checking, loading, by the ULNs loader, the ULNs manager of the application program; when the application program calls a function related to a network, if the ULNs manager of application program exists, transmitting, by a system call hooker, the called function to the ULNs manager; and when the ULNs manager receives the called function, calling the called function by changing a parameter to match the form of a corresponding function of a ULNs, and when a response corresponding to the called function is received, changing the response to match the form of a library and transmitting the response to the application program.
What exactly they claim (claim 1)
1. A method of using a user-layer network solution (ULNs), the method comprising: determining, based on a ULNs loader detecting an execution of an application program, whether a ULNs manager corresponding to the application program exists; loading, by the ULNs loader, the ULNs manager corresponding to the application program based on, as a result of the determination, the ULNs manager corresponding to the application program existing; transmitting, by a system call hooker, based on the application program calling a function related to a network, the called function to the ULNs manager based on the ULNs manager corresponding to the application program existing; and calling, based on the ULNs manager receiving the called function, the called function by changing a parameter of the called function to match a form of a corresponding function of a ULNs and transmitting, based on receiving a response corresponding to the called function, the response to the application program by changing the response to match a form of a library.
