  • Methods and systems for preventing security breaches
    Patent number: 9332021
    Abstract: A security payload is attached to a received binary executable file. The security payload is adapted to intercept application programming interface (API) calls to system resources from the binary executable file via export address redirection back to the security payload. Upon execution of the binary executable file, the security payload replaces system library export addresses within a process address space for the binary executable file with security monitoring stub addresses to the security payload. Upon the binary executable computer file issuing a call to a given API, the process address space directs the call to the given API back to the security payload via one of the security monitoring stub addresses that is associated with the given API. The security payload then can assess whether the call to the given API is a security breach.
