Honeypots

A honeypot is a computer security mechanism set to detect, deflect, or in some manner, counteract attempts at unauthorized use of information systems.

Detecting Honeypot

When entered target system, then if we felt something is wrong. For example,

• Cannot execute common OS commands e.g. ls, cat, etc.

• There are few files under /home/<user> unnaturally.

• There are few users or uncommon users exist in /etc/passwd unnaturally.

• Found either cowrie-env, cowrie.cfg, tpot.yml, dionaea.cfg in system.

We may be able to suspect the system is a honeypot.
