After 66,806 individual records leaked the JFSC have written directly to 2,477 people


The JFSC claims to hold approximately 1 million separate records in its registry system. In many instances, this includes individuals listed on multiple occasions due to their numerous roles and different relationships with multiple service providers. The JFSC says that only names and addresses were accessed with no link to any specific registered entity or any role held.

Of the 1 million, 66,806 individuals have had their names and addresses accessed [illegally by an unknown actor[s]] via an API in circumstances where this information was not already in the public domain through the registry system.

Of the 66,806, the JFSC has directly written  [see below] to the 2,477 people who were assessed as being impacted [at possible harm] in accordance with the obligations under the Data Protection (Jersey) Law 2018.

The JFSC says they only wrote to those people who we have assessed as falling into a higher risk category.  The risk assessment followed an internationally recognised practice using the framework issued by the European Union Agency for Cyber Security (ENISA) [ -/-  ] and have communicated according to the outcomes of the risk assessment.

In addition to the letter, they communicated more widely with a public statement and provided further information on its website.

The JFSC says if an induvial has not received a letter and has any concerns or queries:-

  • They can contact the JFSC via the dedicated email address OR
  • They can contact their local service provider or contact us. The JFSC says it will continue to work with service providers, and they will be able to provide more information to their clients directly.
