Problem

Data Execution Prevention (DEP/NX) is a vulnerability mitigation option that prevents data from being interpreted as code anywhere within the application. This mitigation protects the application stack, heap and other memory data ranges. Executable files that fail to implement this mitigation expose the user to increased risks of malicious code injection.

Problem

Uniform Resource Locators (URLs) are structured addresses that point to locations and assets on the internet. URLs allow software developers to build complex applications that exchange data with servers that can be hosted in multiple geographical regions. URLs can commonly be found embedded in documentation, configuration files, source code and compiled binaries. One or more embedded URLs were discovered to link to raw files hosted on GitHub. Attackers often abuse popular web services to host malicious payloads. Since code-sharing services URLs are typically allowed by security solutions, using them for payload delivery increases the odds that the malicious code will reach the user. While the presence of code-sharing service locations does not imply malicious intent, all of their uses in a software package should be documented and approved. An increasing number of software supply chain attacks in the open source space leverages the GitHub service to deliver malicious payloads.

Problem

Address Space Layout Randomization (ASLR) is a vulnerability mitigation option that forces software components to load on a different memory base address each time they are used. This mitigation is detected as enabled, but rendered ineffective since the set load base address forces the 64-bit image to load within the lower 32-bit memory range. Having a smaller memory range makes ASLR more predictable, and it is therefore easier for malicious code to bypass it.

Problem

Control Flow Guard (CFG/CFI) protects the code flow integrity by ensuring that indirect calls are made only to vetted functions. This mitigation protects dynamically resolved function targets by instrumenting the code responsible for transferring execution control. Because the code flow integrity is verified during runtime, malicious code is less likely to be able to hijack trusted execution paths.

Problem

Control Flow Guard (CFG/CFI) protects the code flow integrity by ensuring that dynamic calls are made only to vetted functions. Trusted execution paths rely on the ability of the operating system to build a list of valid function targets. Certain functions can intentionally be disallowed to prevent malicious code from deactivating vulnerability mitigation features. A list of such invalid function targets can include publicly exported symbols. Applications that enhance control flow integrity through export suppression rely on libraries to mark their publicly visible symbols as suppressed. This is done for all symbols that are considered to be sensitive functions, and to which access should be restricted. It is considered dangerous to mix applications that perform export suppression with libraries that do not.
