Natural Resources Wales Data Breach Exposes Sensitive Employee Diversity Information

Natural Resources Wales (NRW) has disclosed a personal data breach involving a spreadsheet with sensitive diversity-monitoring information belonging to former and current employees.

The organization said the incident affects people employed between April 2013 and March 2018, creating a privacy issue because the dataset may have contained special-category information under UK data-protection law.

NRW said the spreadsheet was inadvertently published, not exposed through a confirmed intrusion, and stressed that not every data category applied to every affected person.

The agency notified the Information Commissioner’s Office and is examining the circumstances and controls behind the disclosure.

According to NRW, the exposed fields included ethnicity, disability status, religion or belief, sexual orientation, Welsh language ability, caring responsibilities, and other equality-monitoring information.

These data elements can reveal aspects of an individual’s identity and, if obtained by malicious parties, could be used for targeted phishing, impersonation, harassment, discrimination, or social-engineering campaigns .

Even without credentials, workforce demographic records may allow an attacker to craft messages that exploit personal circumstances.

The disclosure raises concerns about copying, caching, and screenshots, although NRW said it has received confirmation that the published material has been permanently deleted.

NRW said it acted immediately after becoming aware of the issue. Its response included removing the information from the website, securing confirmation of deletion, and reviewing published material for exposure risks.

The incident was reported to the ICO in line with its obligations. The notification does not indicate when the spreadsheet was published, how long it was accessible, how many people were affected, or whether it was indexed by search engines.

Natural Resources Wales has disclosed a personal data breach involving a spreadsheet containing sensitive diversity information belonging to former and current employees.

The incident affected people employed by Natural Resources Wales (NRW) between April 2013 and March 2018. The organization said the spreadsheet was inadvertently published online, making the information accessible before it was removed.

The exposed data may have included equality-monitoring and diversity details collected from employees. Depending on the individual, the information could include ethnicity, disability status, religion or belief, sexual orientation, Welsh language ability, caring responsibilities, and other equality-related information.

NRW said not every category of personal data applied to every affected employee. However, the information involved is considered highly sensitive because it could reveal personal characteristics that employees may not expect to be publicly accessible.

The breach was discovered following an internal investigation into the disclosure of the spreadsheet. NRW said it acted immediately after identifying the issue to contain the exposure and determine how the data became available.

The organization removed the spreadsheet from the website where it had been published. It also obtained confirmation that the data had been permanently deleted and reviewed other published information to identify similar risks.

NRW reported the incident to the UK Information Commissioner’s Office, the country’s data-protection regulator. The notification was made in accordance with its legal obligations regarding personal data incidents.

Although the organization did not provide technical details about the website, publication process, or spreadsheet access controls involved, the case highlights a common data-exposure risk.
