We are currently seeing a large number of phishing attempts against SU in the form of emails to employees. Several of the emails refer to "Human Resources department" and "Annual Leave 2023" and may look like they come from a colleague, with the colleague's name and email address as the sender. 

If you have received an email from a colleague that looks different in tone and content, ask the colleague if they sent the email. It may be a good idea to ask using another means of communication other than email, such as telephone or chat. 
If the email was not sent by your colleague, contact Helpdesk via Serviceportalen
