Currently, there are increasing numbers of phishing e-mails with the goal of capturing sensitive information such as access data and also distributing male software. They are disguised as an alleged e-mail from the University Library and contain the notice that the validity of your library account is supposed to expire soon.
However, this is a malicious e-mail that was not sent by the University Library, but aims to get you to click on the link it contains. The URL of the link leads to a website that can infect your computer with malware.
The Siegen University Library does not send any e-mails indicating that your libraty account is about to expire.
Further information and advice on how to protect yourself can be found on the information security website of the University of Siegen.
