What type of system did Cyril use to lure attackers and gather information about them?

Cyril utilized a honeypot machine to lure attackers and collect information about their techniques and behaviors. A honeypot is specifically designed to appear as a real, vulnerable system to attract potential intruders. By creating an environment that mimics a target, it serves as both a trap and a research tool, allowing security professionals to observe malicious activities without exposing actual systems.

The primary function of a honeypot is to gather intelligence on the methods used by attackers, providing valuable insights into their strategies and tools. This information can then be used to bolster security measures and understand the threat landscape better. Unlike firewalls, which are designed to block unauthorized access, or intrusion detection systems that monitor and alert on suspicious activities, a honeypot's purpose is to actively engage with attackers to learn from their actions. Threat intelligence portals, while useful for aggregating and analyzing security threats, do not provide the direct interaction that a honeypot does.
