Payment and identity scams (Phishing, Fake-Inkasso)
Payment and identity scams manipulate the authorization process rather than offering an investment. Attackers impersonate banks, authorities, relatives, shops, or debt collectors; steal credentials; or persuade victims to approve a transfer themselves. The durable defense is channel separation: stop, independently locate the real institution, and verify before sharing data or moving money.
The stop–separate–verify procedure
- Stop: do not click, call the supplied number, disclose a code, install software, or approve a payment.
- Separate: open the official app or find contact details independently from a statement or official website.
- Verify: ask whether the request, invoice, account, and urgency are genuine.
- Contain: if data or money moved, contact the bank immediately through its official channel, secure affected accounts, preserve evidence, and report the incident.
German police guidance explains that stolen identity data can come from phishing messages, fake banking sites, shops, or data leaks [1].
Worked scenario
A caller displays the bank’s name and says a “security transfer” must be approved within five minutes. The caller knows the customer’s address and recent transaction amount.
Caller ID and personal details are not independent proof; both can be spoofed or stolen. The request fails channel separation. Ending the call and contacting the bank through the app tests the claim without using the attacker’s route.
Check yourself
A caller claiming to be the bank demands a security transfer. What is the next step?
Credentials may have been disclosed. Which containment steps apply? Select all that apply.
The caller ID shows the bank's name and the caller knows the customer's address. Is that independent verification?
Which action preserves channel separation?
