Memory Injections - CompTIA Security+ SY0-701 - 2.

3

o One technique used by rootkits to gain this deeper level of access is a DLL injection

 DLL Injection

 Technique used to run arbitrary code within the address space of


another process by forcing it to load a dynamic-link library
 Dynamic Link Library (DLL)

 Collection of code and data that can be used by multiple programs


simultaneously to allow for code reuse and modularization in software

Buffer Overflows - CompTIA Security+ SY0-701 - 2.3


Buffer Overflows

o Software vulnerability when more data is written to a memory buffer than it can hold

Race Conditions - CompTIA Security+ SY0-701 - 2.3


 Race Conditions

o Software vulnerabilities related to the order and timing of events in concurrent


processes

 Exploiting race conditions allows attackers to disrupt intended program


behavior and gain unauthorized access

o Understanding Race Conditions

 Race conditions occur when multiple threads or processes access and


manipulate shared resources simultaneously

 Dereferencing

 Software vulnerability that occurs when the code attempts to remove


the relationship between a pointer and the thing that the pointer was
pointing to in the memory which allows changes to be made

 Vulnerabilities stem from unexpected conflicts and synchronization issues

o Exploiting Race Conditions

 Attackers exploit race conditions by timing their actions to coincide with


vulnerable code execution

 Exploitation may lead to unauthorized access, data manipulation, or system


crashes
