## How to check the web link inserted in an e-mail without clicking on it?
> There is a possibility to move the mouse over the weblink without clicking the link. Then information about the web link will be displayed without calling the link.
1. [ ] I ask the sender of the e-mail for the destination address of the weblink by writing back via "Reply".
> Unfortunately wrong.
2. [x] I move the mouse over the web link without clicking it and check the displayed information about the web address (e.g. in the info field).
> **Right answer!**
3. [ ] Unfortunately this does not work. I have to click on the link.
> Unfortunately wrong. Sender names are just as deceptively falsifiable as web links in e-mails.
4. [ ] If the sender name of the e-mail is known to me, there is no need to check the web link further.

3. [ ] The data must be sent to the "confidentiality officer" of your university, who then forwards it encrypted over the internet.

## What does the term "phishing" mean?

## What to do when you receive an email with suspicious email attachment?
1. [ ] I download the content of the attachment to check it.
> Unfortunately not correct. Emails are still a popular way to spread malware across a network. Especially critical are active content and executables in emails, which can contain malicious code that is executed when the document is opened.
2. [x] I only open unexpected files after I could make sure by another way that this email was actually sent by this person.
> **Right answer**
3. [ ] If the attachment is malicious, our central antivirus system always detects that.
> Unfortunately wrong! Even if the detection rate of protection programs is very high, thousands of new computer viruses are circulated every day. Therefore, careful handling of e-mail attachments is just as important as the correct use of anti-virus programs.
4. [ ] An e-mail from a known sender address can always be trusted.
