QueUp developer Rhymin & Partners announced that the application will be made offline following a data breach.
The company said it is working with Cyber Security Brunei to mitigate the impacts of the incident, adding that it will be keeping the public updated.
It said all appointments made prior to yesterday will be honoured and users should present their booking references or identification cards (IC) at the counters.
The Ministry of Health (MoH) in a separate statement said several services under the ministry are affected.
The application is used for booking appointments for health screening for foreign workers as well as the public to reserve a slot for vaccination prior to heading overseas, it said.
Those affected are advised to show proof of appointment to employees at health screening and vaccination centres.
The MoH said the public can make new appointments by calling 2331100 (ext 4) for health screening and 2331100 (ext 207) for vaccination during office hours.
The Postal Services Department in a statement said the appointment for medicine delivery can be made by contacting a nearby post office.
