What happened
In June 2026, the University of Nottingham was the target of a cyber attack, later linked to a ShinyHunters "pay or leak" extortion campaign. Tens of gigabytes of data were subsequently published online and included 455k unique email addresses along with extensive personal information including names, addresses, phone numbers, ethnicities, disabilities, passport numbers and information relating to academic enrolments and fee payments. In a post about the incident, the university advised that the breach affected both "current students, and alumni".

What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Government identifiers
Consider a credit freeze or fraud alert with the credit reference agencies, and watch for accounts you did not open. - Sensitive personal characteristics
Under UK/EU GDPR you have a strong right to erasure here — exercise it with the service and with any site republishing the data. - Home addresses
Get your address removed from data brokers — they re-list roughly every four months, so this needs repeating. - Dates of birth
Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number. - Phone numbers
Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider. - Confirm you were actually in it

This breach put your details on data-broker sites
Because University of Nottingham exposed sensitive personal characteristics and home addresses, this is one of the breaches that feeds people-search and data-broker sites. Those sites scrape leaked databases, combine them with public records, and republish the result as a searchable profile — which is how a single breach turns into a permanent public listing. Removal works, but brokers typically re-list within about four months, so it has to be repeated.

How urgent is this now?
This breach is recent, so the data is actively traded and the risk is at its highest right now.
Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
