Explanation

Phishing tricks users into revealing credentials through fake messages or lookalike sites.

A Denial of Service attack floods a service with excessive requests until it stops responding.

A Man-in-the-Middle attack secretly intercepts communication passing between two parties.

Ransomware encrypts a victim's files and demands payment for the key.

Each attack thus matches its own defining behaviour.

Phishing relies on social engineering, while a DoS attack overwhelms resources by sheer volume.
