You have correctly identified that this is a legitimate email.

The attachment at the bottom of the email is named “problemloesung.pdf.” The file extension is “.pdf”, a typical format. This is often used to send information and documents digitally. Unlike the “.exe” extension, it is not one of the particularly dangerous formats. Therefore, we would initially assume that this is a legitimate message. Nevertheless, there are still various aspects that must be considered when checking the attachment (even for formats that are not particularly dangerous, e.g. “.pdf”) (see further information).

- Programmes for opening formats that are not particularly dangerous may have vulnerabilities that mean that any format can pose a risk, e.g. due to security gaps in the code of older versions of PDF programmes.

- Even harmless formats can contain links that may pose a threat. In this case, the tips for recognising fraudulent links must be applied accordingly.

The information available in this case regarding the attachment suggests that this email is legitimate.
