Cowrie is a silly-looking shell that is sometimes used to play dress-up or as a toy. But in the computer world, cowrie is also a type of software called a honeypot.
A honeypot is like a pretend computer that is set up on purpose to attract bad guys (called hackers) who want to do bad things to real computers. The idea is that the hackers will try to break into the honeypot instead of a real computer, and then the people who set up the honeypot can learn how the hackers did it and maybe find ways to protect real computers from those attacks.
Cowrie is a specific type of honeypot that looks like a pretend computer that bad guys might want to break into. Like the shell that it's named after, the cowrie honeypot is small and white, and it sits quietly on a network waiting for hackers to try and break in. When a hacker tries to get in, cowrie records what the hacker is doing, like what password they tried to use or what commands they entered.
Cowrie is a helpful tool for computer security experts who are trying to make the Internet a safer place for everyone.
