What you should do

If you are, or have been at any time since 2003, an employee, student, guest, or external partner at DTU, information about you may be included in the data breach.

DTU therefore recommends that you:

  • be particularly alert to suspicious emails, text messages, and telephone calls, including when the sender or caller appears to know information about you or your connection to DTU
  • do not disclose passwords or other confidential information in response to unexpected enquiries
  • do not approve unexpected login or authentication requests
  • change your password on services where you have reused your DTU password
  • consider registering a credit alert against your CPR number at Borger.dk (in Danish)

If you have name and address protection, you should be particularly vigilant. If information about your name and address has fallen into the hands of unauthorised persons, this may increase the risk of unwanted contact, being located, or other forms of harassment.

You can read more about how to protect yourself at Sikkerdigital.dk (in Danish).
