Sandboxing Restrictions
Sandboxing isolates applications from each other and the core system to prevent malicious activities. Bypassing sandboxing allows applications to access resources and data outside their designated areas. This may enable an app to access system settings or modify other application data, which are normally forbidden. Breaking the sandbox can facilitate broader system-level control, but also increases the risks of vulnerabilities.
-
Address Space Layout Randomization (ASLR)
ASLR randomizes the memory addresses of critical system components, making it difficult for exploits to predict where to inject malicious code. Bypassing ASLR typically involves information leaks or memory corruption techniques to discover the location of key memory regions. By successfully predicting memory locations, attackers can bypass ASLR’s intended defense and execute arbitrary code within a compromised system.
-
Kernel Patch Protection (KPP)
KPP, also known as “integrity protection,” monitors the kernel for unauthorized modifications. Bypassing KPP allows changes to be made to the kernel without triggering security alerts or system shutdowns. This is critical for installing kernel-level tweaks or modifications that fundamentally alter the operating system’s behavior. Circumventing KPP requires complex exploitation techniques and is often the most difficult hurdle to overcome.
