Phishing
Phishing is a social-engineering attack that uses deceptive messages or pages to make a person reveal information, execute an action, or deliver an attacker-controlled payload.
Mechanism
A message creates urgency or trust, directs the recipient to a deceptive destination, and attempts to capture credentials, induce a payment, or cause execution. The key defensive question is whether the identity, destination, and requested action can be independently verified.
Indicators to watch
Watch for unusual sender domains, look-alike addresses, unexpected login pages, shortened or mismatched URLs, new inbox rules, impossible-travel sign-ins, suspicious OAuth consent, and reports from users.

Defensive controls
Use phishing-resistant MFA where possible, secure email gateways, SPF/DKIM/DMARC, URL and attachment analysis, user reporting, domain protection, browser isolation, and rapid credential/session revocation.
Recommended security control
Email gateway / Microsoft Defender for Office 365
Use an authorized mail-security lab to inspect headers, links, and authentication results. Never send deceptive messages to real users without permission.
