A secure process may be created which does not allow code to be injected into it, does not allow modification of its memory or inspection of its memory. The resources protected in a secure process include all the internal state and threads running in the secure process. Once a secure process is created, the secure process is protected from access by non-secure processes. Process creation occurs atomically in kernel mode. Creating the infrastructure of a process in kernel mode enables security features to be applied that are difficult or impossible to apply in user mode. By moving setup actions previously occurring in user mode (such as creating the initial thread, allocating the stack, initialization of the parameter block, environment block and context record) into kernel mode, the need of the caller for full access rights to the created process is removed. Instead, enough state is passed from the caller to the kernel with the first system call so that the kernel is able to perform the actions previously performed using a number of calls back and forth between caller and kernel. When the kernel returns the handle to the set-up process, some of the access rights accompanying the handle are not returned. Specifically, those access rights that enable the caller to inject threads, read/write virtual memory, and interrogate or modify state of the threads of the process are not returned to the caller.

A dynamic and synchronized real-time captioning system and method for streaming media. A streaming encoder module can provide a code injection to marry textual data and audio/video (AV) data in order to form a text and/or audio stream. A streaming control module can allow an end-user to specify font format utilized to embed into an AV stream. A delay enhancement tool can be adapted to adjust speed of the text and/or audio stream, which allows the end-user to receive the text and/or audio stream at a proper speed. A customized graphical user interface (CGUI) can be adapted to assist with streaming administration to provide an encoding option, caption source location, delay control and slide control. Therefore, the captioning system can be able to synchronize and deliver the textual data and the AV data for live media streaming at an end-user's system.

Systems (100) and methods (400) for protecting data accessed through a network connection. The methods involve transferring security software (150) from an external memory device of a client computer (102) to an internal memory device of the client computer. The security software is operative to protect data communicated to and from the client computer via communication links. The security software is also operative to provide a web browser (110₁, 110₂, . . . , 110_p) which executes in user mode on a trusted secured desktop (904) configured to run simultaneously with an unsecured desktop (902) of the client computer. The security software is further operative to provide a security service to the web browser. The security service includes at least one service selected from the group consisting of a keylogger prevention service, a code injection prevention service, and a screen scraper protection service.

Trustworthy systems require that code be validated as genuine. Most systems implement this requirement prior to execution by matching a cryptographic hash of the binary file against a reference hash value, leaving the code vulnerable to run time compromises, such as code injection, return and jump-oriented programming, and illegal linking of the code to compromised library functions. The Run-time Execution Validator (REV) validates, as the program executes, the control flow path and instructions executed along the control flow path. REV uses a signature cache integrated into the processor pipeline to perform live validation of executions, at basic block boundaries, and ensures that changes to the program state are not made by the instructions within a basic block until the control flow path into the basic block and the instructions within the basic block are both validated.

The present invention provides a method and system for capturing the call stack of a currently-running thread at the time a profiler interrupt occurs. The thread context of the thread is determined before a full push of the thread context is performed by the CPU architecture. The hardware state at the time of the interrupt is used to aid in determining which portions of memory to search for portions of the thread context. Based on the hardware state and the software state of the thread at the time of the interrupt the thread context is captured. Code may also be injected into a thread to capture a thread's call stack. The state of the thread is altered to induce the thread to invoke the kernel's call stack API itself, using its own context.

The invention relates to a method for detecting a code security hole based on constraint analysis and model checking, which can extract the source code of a C program in a constraint way and detect the security hole of the program with the model checking. The main content comprises the following steps: buffer attribute information which is involved in the source code of the C program is extracted with a constraint analysis technology; the corresponding ASSERT sentence information of attribute generation, attribute transmission and attribute constraint is inserted into variable declaration, variable assignment and function call site with the buffer attribute information; the inserted code can be taken as the input of the model checking to judge whether the program is accessible, find whether the dangerous points in the program really has an accessible path and finally find the security hole in the source code. Currently, independent model checking can not detect the security hole of the buffer and the like, the method combines the static detecting technology of the constraint analysis with the model detecting technology to realize the detection of the security hole of the buffer overflow and the like, wherein, the detecting precision of the method is higher than that of the general static detecting technology. By extracting the other dangerous function information of the source code, corresponding inserting process is carried out. The invention also can detect the security holes such as formative character string, code injection, privilege escalation, etc.

An implementation of the inventive concept enables an outside entity to alter user's internet experience on a system-wide level. Specifically, inventive system enables a merchant, a distributor or any other entity to send contextually-relevant messages directly to the user's computer. Upon the receipt of the messages by the controller application residing on the user's computer, the messages are shown to the user by being incorporated into representation of various resources viewed by the user. For example, the received messages are incorporated into web pages viewed by the user by means of code injection. This way, the merchant, distributor or any other entity may provide targeted advertising to the user in a contextually relevant manner. Specifically, the controller application residing on the user's computer may detect requests for specific resources issued by the user in accordance with a predetermined criteria and incorporate the aforesaid received messages into those selected resources.

Method, apparatus, and computer readable medium for monitoring code injection in a computer is described. In some examples, at least one application programming interface (API) call configured to inject data into a process executing on the computer is intercepted. The data is parsed to identify instruction code to be performed by the process. The instruction code is compared with instances of predetermined instruction code to produce a score for the instruction code. The data is prevented from being injected into the process in response to the score satisfying a threshold score. The data may be allowed to be injected into the process in response to the score not satisfying the threshold score.
