How can I know that I have been the victim of a phishing attack? There various signs that should make you suspicious:

• After entering your login name or credentials and PIN to log in, for example, you will be asked to enter several unused TAN transaction numbers and the corresponding sequential numbers on a manipulated subsequent page. When entering a TAN, please always make sure that it is related to your order (e.g. a bank transfer).
• During the online banking process, a new browser window will open. You will be asked to enter your bank code, PIN and/or one or more TANs.
• You will be prompted to enter one or more TANs during or after completing a transaction. There is often a message that the previously entered TAN has already been used up or is incorrect.
• Your secure connection to online banking is interrupted after you have entered your PIN and TAN.
• Your Internet browser is closed for no apparent reason. A corresponding error message may be displayed.
• After completing a transaction by entering a TAN, your Internet browser displays the error message that online banking is no longer accessible. The message will be displayed repeatedly if you want to start online banking at a later time.

If any of the above anomalies occur or you have any other reason to think or suspect that something is wrong, you should take action immediately:

1. Download another statement of the transactions on your account (or check a paper statement) and immediately block your bank account and your access to online banking. The quickest way is to call up the online banking login screen, for example, and enter the wrong PIN three times in a row. Or call the central blocking emergency number 116 116 (from abroad +49 116 116) and have your access blocked by telephone.
2. Then contact your bank immediately and report the anomalies. If necessary, it may be possible to reverse the transactions on your account.
3. If you have become a victim of a phishing attack using a Trojan, you must professionally clean the malware from your PC.
