Understanding endpoint-based attacks

On any corporate network, you will always discover that there are more endpoints (clients) than the total number of network devices and security appliances. For a threat actor, this is like discovering a gold mine with a lot of data to steal, user credentials to obtain, and even an army of potential zombie machines just waiting to be controlled by the attacker. In this section, we will be discussing the most popular types of endpoint-based attacks within the cybersecurity industry.

Buffer overflows

The developers who create the applications and the operating systems we commonly use each day will have also created a special storage unit called a buffer. A buffer is a small area in memory that is used to temporarily store data while an application or the operating system uses it. This buffer is limited in terms of storage size and it's usually small. Once an application or operating system finishes using the data within the buffer, it clears...
