Because it’s been zero days since the security flaw was last exploit, the attack is termed as zero-day exploit or zero-day attack. Organized, skilled, and well-funded attackers exist. An exploit is a program or piece of code that finds and takes advantage of a security flaw in an application or system so that cybercriminals can use it for their benefit, i.e., exploit it. The shell code is the payload of the exploit -- software designed to run once the target system has been breached. With that said, however, there are several different types of exploits, each of which works in a different way. PoC exploits are not meant to cause harm, but to show security weaknesses within software. This is music to an attacker's ears, as they make good use of machines like printers and cameras which were never designed to ward off sophisticated invasions. What it does is open a channel that cyber criminals can use to communicate with your system and feed it codes which include different types of commands. “Ransomware, data breaches, phishing and security exploits are the top threats to cyber security.
