Abstract
A new system service table is dynamically generated to allow dynamic insertion of code between the caller of a native operating system function, in user or kernel mode, and the operating system's implementation of the native operating system function. The dynamically inserted code has full access to the function parameters, such as arguments. The new system service table has encoded values that are relative to the base address of the new system service table and which include the function addresses of the native operating system functions corresponding to original system service table entries in the original system service table.
