Sure has been the victim of a phishing attack that stole just under 400 suppliers', employees' and former employees' data.
The information taken was from people across Guernsey, Jersey and the Isle of Man, but the telecoms firm has said it was 'limited in nature', and no customers' data was accessed.
Tim Stonebridge, Chief Security Officer at Sure, said: "The data was limited in nature and no existing customers’ data has been compromised.
“Contacting those affected has been our priority and we have now informed them and offered relevant advice, as well as making the Data Protection Authorities in each island aware of the attack."
The data breach was the 'result of the human error', Mr Stonebridge explained.
"The loss of data was the result of human error and only affected one staff email account which our systems identified and subsequently shut down. The attack was contained and Sure’s systems were never compromised.
“While the data that has been stolen cannot be used in isolation, we have advised those affected to be extra vigilant.
“We’d like to apologise to all those who have been affected. Security is of paramount importance to Sure and our employees undergo regular cybersecurity training. We are constantly reviewing our training programmes and will use this example to inform future learning.”
