There are two Linux system calls for loading a kernel module - init_module and finit_module. By leveraging init_module, I bypassed a filesystem-based SELinux rule that prevented me from loading a kernel module through traditional means (e.g., insmod).

and remediation operations. This success is a problem
for attackers, and malicious actors have worked to
find new ways to evade EDR detection capabilities.
The huge profits of ransomware have led to a rapid evolution and professionalization of the wider cyber crime industry, and the rapid growth of a supporting underground marketplace of products and service providers.
