You have received a strange e-mail that looks like spam or phishing, comes from an unknown sender, is dubious, asks for Bitcoin payments, asks for your login data or asks me for your credit card number? You can find out about fraud on the Internet through phishing e-mails at https://www.kaspersky.com/resource-center/threats/spam-phishing and https://staysafeonline.org/stay-safe-online/identity-theft-fraud-cybercrime/spam-and-phishing/.
Please note that the Studo mail client only displays the e-mails from your university - the phishing mail has nothing to do with Studo but with your university e-mail address. You can also visit the website of your university for further information about phishing.
If you have received a phishing mail, please delete it immediately and do not follow the instructions in the mail.
