摘要： An exemplary method for preventing exploitation of byte sequences that violate compiler-generated instruction alignment may comprise: 1) identifying instantiation of a process, 2) identifying an address space associated with the process, 3) identifying, within the address space associated with the process, at least one control-transfer instruction, 4) determining that at least one byte preceding the control-transfer instruction is capable of resulting in an out-of-alignment instruction, and then 5) preventing the control-transfer instruction from being executed. In one example, the system may prevent the control-transfer instruction from being executed by inserting a hook in place of the intended instruction that executes the intended instruction and then returns control flow back to the instantiated process. Corresponding systems and computer-readable media are also disclosed.

摘要： A method for preventing subversion of address space layout randomization (ASLR) in a computing device is described. An unverified module attempting to load into an address space of memory of the computing device is intercepted. Attributes associated with the unverified module are analyzed. A determination is made, based on the analyzed attributes, whether a probability exists that the unverified module will be loaded into a number of address spaces that exceeds a threshold. The unverified module is prevented from loading into the address space if the probability exists that the unverified module will be loaded into a number of address spaces that exceeds the threshold.

摘要： When a program is loaded for execution, all code pages of the program except the one containing the entry point are set to be non-executable. When the executing program attempts to jump between code pages, an exception is thrown. Responsive to such an exception, a control flow graph of the program is examined, to determine if the attempted jump between code pages is expected. If the attempted jump is not expected, it is determined that the program is attempting a malicious activity. If the attempted jump is expected, the code page to which the program is attempting to jump is set to be executable, and control is returned to the program such that the jump executes.
摘要翻译：当程序加载执行时，除了包含入口点的程序之外，程序的所有代码页都被设置为不可执行。当执行程序尝试在代码页之间跳转时，抛出异常。响应于这种异常，检查程序的控制流程图，以确定是否期望在代码页之间尝试跳转。如果不希望尝试跳转，则确定程序正在尝试恶意活动。如果尝试跳转，程序尝试跳转的代码页被设置为可执行，并且控制返回到程序，使得跳转执行。

摘要： Computers are monitored for malware communicating directly with the NIC. The infection of computers with NIC level malware is detected. Operating system level network packet transmission statistics are monitored, as are transmission counters maintained by the NIC. The operating system level transmission statistics are compared to the NIC level transmission counters for a given period of time. If the NIC counters indicate the occurrence of a greater number of transmissions than as is indicated by the operating system level statistics, it is concluded that the computer is infected with NIC level malware.

摘要： A DRM server parses a request received from a client for a content identifier and client classification information. The content identifier identifies the requested content and client classification information describes the capabilities of the client. The DRM server determines a policy for the requested content. The policy specifies rules for determining access rights for the content responsive to the capabilities of the client. The DRM server determines access rights for the requested content responsive to the capabilities of the client and the policy. The DRM manager then provides the requested content and the determined access rights to the client.
