Signs of a phishing campaign against the University of Oldenburg

Dear Sir or Madam,

For several days now, fake e-mails have been sent with a fake sender name of the University of Oldenburg. Please do not click on any links in these emails and do not enter any user names and/or passwords. Opening the links will either take you to external websites and an attempt will be made to obtain your login details or to install malware on your end device.

However, if you have done this, please contact the IT Services service desk immediately and they will take care of restoring your user account and removing the malware. Please also disconnect all network connections (LAN and/or WLAN) immediately.

If you receive unexpected e-mails from internal or external sources, please make a short phone call to check whether the e-mail is from them.

Yours sincerely,

Christoph Pierl

1. Sentinel One (see installation in the green menu on the left)
2. Current system updates, especially Windows updates (see green menu on the left)

What should I pay attention to when working on the Internet?

1. Before filling out a form, make sure that the page is encrypted(https://...)
2. Check the main domain (especially the last two elements of the host name, e.g. https ://mail.uni-oldenburg.de/ , https ://kunden.commerzbank.de/lp/login. Suspicious here would be https ://mail.uni-oldenbug.de/ or https ://mail.uni-oldenburg.com/ or https ://kunden.comerzbank.com/lp/login

3. For links in the browser or in emails, move the mouse over the link(do not click on it!) and pay attention to the link destination displayed (in the bottom left window or in the pop-up display).
