What is a typical target of a trojan on a Linux system?

A trojan on a Linux system commonly targets kernel modules because these components are integral to the operating system's functionality and can provide deep access to system resources. Kernel modules operate at a low level within the system and can manipulate core operations, making them attractive targets for malicious code aiming to gain elevated privileges or compromise system integrity.

By targeting kernel modules, a trojan can achieve significant control over the system, allowing it to execute malicious actions without detection. This can include intercepting system calls, altering operating behaviors, or even installing additional malicious software.

In contrast, shared libraries, while important, are typically not the primary focus for trojans aiming to gain complete system control. Boot sector files are more relevant to systems like Windows, and System32 DLL files specifically pertain to the Windows operating system rather than Linux. Thus, the focus on kernel modules highlights the specific vulnerabilities and operational structure of Linux environments.
