Problem

Software developers use programming and design knowledge to build reusable software components. Software components are the basic building blocks for modern applications. Software consumed by an enterprise consists of hundreds, and sometimes even thousands of open source components. Software developers publish components they have authored to public repositories. While a new software project is a welcome addition to the open source community, it is not always prudent to indiscriminately use the latest components when building a commercial application. Irrespective of the software quality, the danger of being the first to try out a new project lies in the fact that the software component may contain novel, currently undetected malicious code. Therefore, it is prudent to review software component behaviors and even try out software component in a sandbox, an environment meant for testing untrusted code.

Problem

Software components contain executable code that performs actions implemented during its development. These actions are called behaviors. In the analysis report, behaviors are presented as human-readable descriptions that best match the underlying code intent. While most behaviors are benign on their own, some might become important for analysis when observed alongside other capabilities the component exhibits. This issue is reported for files that can enumerate user information and make HTTP requests. While presence of this behavior combination does not imply malicious intent, it is advised that the reported files are reviewed. One example of acceptable use for this type of data collection is the opt-in telemetry for software debugging purposes.

Problem

Software components sometimes need to interact with higher privilege parts of the operating system, often requiring administrative access to accomplish a task. System certificate stores are databases that define the chain of trust for a machine. These databases control the list of websites the machine can securely connect to, and the list of applications that the operating system implicitly trusts. For that reason, attackers often abuse system certificate stores to ensure their malicious code executes without being detected by security solutions. While the presence of code that tampers with system certificate stores does not necessarily imply malicious intent, all of its uses in a software package should be documented and approved. Only select applications should consider using functions that interact with system certificate stores. One example of acceptable use for such functions is adding publisher certificates to the system trust store during software installation.

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. Top-level domains (TLD) are a part of the Domain Name System (DNS), and are used to lookup an Internet Protocol (IP) address of a requested website. There are a few different types of top-level domains. Generic, sponsored and country-code TLDs are generally accessible to the public. Registrars that govern the assignment of domain names within the TLD may choose to sell specific domain names to an interested party. However, some registrars are known to have less strict rules for assigning domain names. Attackers often abuse gaps in governance and actively seek to register their malicious domains in such TLDs. This issue is raised for all domains registered within TLDs that harbor an excessive number of malicious sites. While the presence of suspicious TLDs does not imply malicious intent, all of its uses in a software package should be documented and approved.
