FeaturePhishingSpear phishingVishingSmishing
What sets it apartThe base form: a fraudulent message, usually email, posing as a trusted partyTargeting: aimed at specific people or groups using tailored detailsChannel: a phone call or other voice communicationChannel: SMS or other text messages
Typical lureA link to a fake login page, an attachment, or a request for sensitive dataA request that correctly names a real colleague, project, or processA caller posing as the help desk, a bank, or a managerA text pointing to a deceptive website or phone number
Why it seems trustworthyFamiliar branding and a familiar display nameAccurate personal or organizational detailsA familiar caller ID, which can be spoofedIt arrives on a personal phone
What still exposes itThe real sender address and link destinationThe request itself: credentials, payment, or skipping an approvalAn unsolicited request for a password or a sensitive actionAn unexpected link or callback number inside the text

Cheat sheet

  • Security awareness aims to improve everyday security behavior
  • Visible leadership participation reinforces security culture
  • Security learning includes everyone who uses organizational systems or data
  • Tailored training adds to general awareness for privileged and security roles
  • Security learning must evolve with threats and workplace changes
  • Phishing simulations should support learning rather than public punishment
  • Users need clear expectations for recognizing, responding to, and reporting security concerns
  • AI-assisted identification supports staff reporting under established playbooks
  • Social engineering manipulates people rather than relying only on technical flaws
  • Spear phishing targets particular people or groups
  • Vishing uses voice communication for social engineering
  • Smishing uses text messages to deliver social engineering requests
  • Urgency and emotional pressure are common manipulation cues
  • Verify suspicious requests through an independently trusted contact route
  • Report suspected phishing without interacting with its links or attachments
  • A familiar label or logo does not establish a link's destination
  • AI-generated phishing can be fluent and free of spelling errors
  • Suspected disclosure of credentials requires prompt reporting and protective action
  • Strong passwords combine length with unpredictability
  • Unique passwords limit the spread of a single account compromise
  • A password manager helps users maintain distinct strong passwords
  • A claimed support role does not justify disclosing a password
  • MFA adds protection when a password alone is insufficient
