More and more people are falling victim to fraudulent bank calls, where scammers pose as employees of well-known banks. The goal is to obtain sensitive information, such as push TANs, to carry out transfers.
Recently, reports have increased about fraudulent calls where criminals pose as bank employees. This scam, highlighted by the Consumer Center Hamburg, aims to obtain sensitive bank data by pretending to curb suspicious account activity. They particularly target the so-called push-TAN, which enables transactions.
Fake Bank Calls and Their Dangers
The Consumer Center Hamburg reports that the perpetrators pose as employees of well-known banks such as Haspa, Solarisbank, Commerzbank, Deutsche Bank, or Postbank. Their approach appears highly professional and convincing, leading many victims to disclose personal information. The danger lies in the potential financial loss from sharing these details.
The fraudsters often use fake phone numbers that closely resemble those of the banks. In one documented case, the displayed number matched the Haspa hotline except for the last digit. However, banks emphasize that they never call customers unsolicited or ask for personal data. Unlike direct debits, transactions authorized by TAN are generally irreversible.
