Problem

Operating systems provide multiple integration points for applications to insert themselves in the system startup sequence. Startup sequence is executed in its entirety each time the computer system powers on. For that reason, attackers typically try to register their malicious code in the system startup sequence. When malicious code is registered to start with the operating system, it achieves persistence, as it becomes permanently installed. While the presence of code that modifies the system startup sequence does not necessarily imply malicious intent, all of its uses in a software package should be documented and approved. Only applications that require constant background operation should consider installing themselves as a part of the startup sequence. One exemption to this recommendation would include running the application after the first system reboot to complete the software installation.

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

Software components sometimes need to interact with higher privilege parts of the operating system, often requiring administrative access to accomplish a task. Machine power settings are high privilege functions that can change the power state of the device. This includes the ability to reboot and shutdown computer systems. Attackers often abuse machine power settings to force a system reboot, upon which malicious code can infect the system and gain persistence. While the presence of code that tampers with machine power 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 the machine power state. One example of acceptable use for such functions is prompting users to reboot their system during complex software installations.
