Problem

Proprietary ReversingLabs malware detection algorithms have determined that the software package contains one or more malicious files. The detection was made by a machine learning model. This malware detection method is considered proactive, and can typically identify the malware threat type. The detection is strongly influenced by behaviors that software components exhibit. Behaviors similar to previously discovered malware and software supply chain attacks may cause some otherwise benign components to be detected as malicious.

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

Software components sometimes need to interact with higher privilege parts of the operating system, often requiring administrative access to accomplish a task. Operating systems include a complete network stack with many services that allow the machine to connect to the internet. Some of these services are used to secure network access. For that reason, attackers often aim to tamper with system network settings. Disabling firewalls and other network security features enable the malicious code to execute without being blocked. While the presence of code that tampers with system network settings 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 network settings. One example of acceptable use for such functions is allowing specialized applications to use non-standard network ports by updating the firewall allowlist.

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. Open source communities depend on the work of thousands of software developers that volunteer their time to maintain software components. Software developers build up the reputation of their open source projects by developing in public. Modern source code repositories have many social features that allow software developers to handle bug reports, have discussions with their users, and convey reaching significant project milestones. It is uncommon to find open source projects that omit linking their component to a publicly accessible source code repository.

Problem

Control Flow Guard (CFG/CFI) protects the code flow integrity by ensuring that indirect calls are made only to vetted functions. This mitigation is detected as enabled, but its effectiveness is impacted by the use of outdated precompiled code. It was determined that the application had been linked against static libraries produced by multiple toolchain versions. Because some of them predate the general availability of the control flow guard vulnerability mitigation, it is likely that protection coverage gaps exist.
