Latest news: Phishing

There have been a number of reports in the press recently about attempts to defraud online banking users by “phishing” – or “password fishing”.

How to keep your logon data safe from spies

In this scam, Internet users receive an e-mail purported to be from their bank, requesting them on some pretext or other to log on at their online banking site via a link provided in the mail.

However, the link takes the recipient to a fake Internet site that is virtually identical to the genuine article. Visitors are then requested to enter their user number, PIN and possibly also a TAN.

Once users have entered this data and confirmed the transfer, the logon information is communicated to an unauthorised computer, usually out of the country. The data can then be used unlawfully.

This is how you protect yourself

First, you can be sure that the Commerzbank will never ask you by e-mail to log on for an update of your personal data or similar.

You can therefore safely ignore e-mails such as this. Never use the links specified in such mail. If in doubt, contact our help desk.

Phone +49 (0)40 3 76 95 100 (Monday to Friday from 8.00 am to 7.00 pm) or fill in the contact form.

You are also welcome to send us your message via fax to the following fax number: +49 (0) 40 - 3 76 95 400.

We also recommend the following procedure for logging on:

  • Key the address in the browser window manually, or use an entry you have previously created in the “Favourites” menu.
  • Do not use any links sent in e-mails, even if the mail appears to be from a trusted source.
  • Do not fill in electronic forms in e-mails that ask you to provide logon data.
  • Use a current browser. You can obtain security updates from the producer of your operating system, for example from for Windows operating systems.

If the worst happens: what to do if you’ve navigated to the link

If you think you’ve fallen victim to a ”phishing” mail and your logon data has been compromised by fraudsters, here’s what to do:

  • If you have made known your logon data, please immediately disable your access in the Online Banking/Administration menu and contact your Commerzbank branch or the help desk.
