Simple explanation

Understand it

Scam messages often borrow a familiar situation: a parcel, unpaid bill, job offer or account alert. Good spelling, a familiar sender name or a company logo does not make a message genuine.

Pause when a message demands immediate payment or sign-in. Open the company’s app or contact it using details you already trust. A real problem should be verifiable outside that message.

Technical explanation

Under the hood

Display names, spoofed sender information, compromised accounts and redirects can all mislead recipients. Email authentication helps verify sending infrastructure but cannot prove that every authenticated message has a benign purpose.

Practitioner explanation

Practitioner perspective

Preserve original message headers and URLs through approved reporting tools. Correlate domain, delivery and account activity; avoid uploading private correspondence to public analysis sites. A passed SPF/DKIM check is supporting context, not a verdict.

Phishing

A person pauses to inspect a friendly-looking parcel that conceals a hook.

The design of a page does not prove who will receive the information.

How to use this example

Inspect components & read every step
  • You

    The person making the decision in this fictional example.

    Example: You decide whether to share information, approve a request or check it first.

  • Fake page

    A page impersonating a legitimate service.

    Example: A copied sign-in page can send your entered password to a scammer.

  • Scammer

    A person using deception to obtain money, information or access.

    Example: They send a misleading link and copy a familiar brand.

  • Real service

    The legitimate service you intended to use.

    Example: You open its known app instead of following a suspicious message link.

Password entered

The design of a page does not prove who will receive the information.

  1. Fake page You: Sign in now. A lookalike page presents an urgent sign-in request.
  2. You Fake page: Password entered. The password is sent to the page you are using.
  3. Fake page Scammer: Secret copied. The scammer can receive the submitted information.

Real service opened

A known independent route avoids letting the message choose where you sign in.

  1. Fake page You: Urgent request. A page asks you to act immediately.
  2. You Real service: Known app. You open the service through your saved app or address.
  3. Real service You: Account status. Review whether the claimed problem exists in the real account.

Typed codes can be stolen too

Ordinary typed MFA codes can be relayed; MFA does not make a fake form safe.

  1. You Fake page: Typed code. A fake page also asks for a current sign-in code.
  2. Fake page Scammer: Code copied. The code can reach the scammer before it expires.
  3. Scammer Real service: Code used. The real service may accept a relayed code; site-bound passkeys work differently.

Urgent message

A parcel is supposedly blocked.

Rushed response

  1. Urgent message. A parcel is supposedly blocked.
  2. Link opened. The page asks for a small fee.
  3. Card entered. Details reach an unverified recipient.

A small amount can disguise a larger information risk.

Independent check

  1. Pause. Do not follow the demand.
  2. Order checked. Open the seller’s known app.
  3. Request verified. Check whether an actual delivery issue exists.

A separate trusted route breaks the message’s control.

What could go wrong

A small delivery fee becomes the reason to enter card details on an unrelated page.

What you can do

  • Check orders through the shop or courier app you normally use.
  • Report suspicious messages through the service or your workplace reporting channel.

Common mistakes

  • Scams need not contain bad grammar.
  • Replying to ask whether a scam is real does not independently verify it.
