We explain below how to recognize the majority of phishing emails. Please report suspicious mails or mails you are not sure about. Send them as an attachment to postmasterspam prevention@uni-tuebingen.de
Emails can be forwarded as an attachment in the following ways:
Outlook (Windows): The selected email can be forwarded as an attachment using the keyboard shortcut CTRL + ALT + F.
Outlook (Mac): Right-click on the email and select “Forward as Attachment”.
Thunderbird: Right-click on the email and select “Forward and Redirect” / “As Attachment”.
Webmailer: Right-click on the email and select “Forward” / “As Attachment”.
Subject lines such as "Warning/ Warnmeldung", "account upgrade/ Konto-Upgrade", "mailbox full/ Mailbox über Größenbeschränkung" are meant to make the message sound important.
Usually, the email contains a threat (in poor German or English) to close or delete the account. This is meant to make you respond immediately – without taking time to think.

You can easily see that this email was not really sent from "webmaster@uni-tuebingen.de" and that the reply goes to an external address.
How do I identify the actual sender address of an email?
Outlook (Windows): Hover the mouse over the sender’s name – the full email address will be displayed.
Outlook (Mac): Click on the sender’s name to view the full email address.
Thunderbird: In the opened email or the preview pane, hover the mouse over the sender’s name to see the address.
Webmailer: Hover the mouse over the sender’s name – the full email address will be displayed.
The University IT center (ZDV) never asks for your password via email!
Expressions like "F-Secure" and "password secure/ Passwort ist verschlüsselt" are meant to give the appearance of security. This is a sham!

Even though a "uni-tuebingen.de" sender address was used, this email did not originate
webmaster@uni-tuebingen.de.
Sender’s addresses can easily be falsified.
As in the first example, the answers go to an external address.

This phishing email tries to lure unsuspecting users with a link to a form in which you are supposed to enter your access data. In the webmailer you can easily see the quota status (circled in green).

This is an example of a form linked via a phishing email.
The source locator (URL) indicates that this is not a University of Tübingen web page.

This is an example of a form created by the phisher using Google Docs. The data is transferred securely (https) – but not to the University of Tübingen.
Browsers mark encrypted links in various ways (e.g. on a colored background, with a “locked” symbol), but this only means the data is encrypted when it is sent. You must check the addressee if you transmit sensitive data!
