A "watering hole" attack is a security exploit in which the attacker seeks to compromise a specific group of end users by infecting websites that members of the group are known to visit.

The goal is to infect a website that members of a targeted community frequently use with malware. Once a user visits the compromised website, malware can be delivered to the user’s system, exploiting vulnerabilities on their device.

This attack vector is used in scenarios where attackers want to breach secure environments indirectly by targeting less secure points in a network's ecosystem, such as third-party software used within the organization.

Code Red is not ICS specific malware; it was a famous worm that targeted computers running Microsoft's IIS web server. Unlike Flame, Havex, and Stuxnet, which were specifically designed to target industrial control systems or perform espionage related to ICS environments, Code Red was aimed at exploiting vulnerabilities in internet-facing software to perform denial-of-service attacks and other malicious activities.References:

TCP (Transmission Control Protocol) is a connection-oriented protocol used in the majority of internet communications.

Connection-oriented protocols like TCP require a connection to be established between the communicating devices before data is transmitted. This ensures reliable and ordered delivery of data.

TCP manages this by establishing a handshake mechanism (TCP three-way handshake) to set up the connection prior to transmitting data and properly terminating the connection once the communication session has completed.
