Yn gyntaf, gallaf gadarnhau bod pob aelod o staff GIG Cymru a gafodd eu heffeithio ac y bu modd eu hadnabod wedi cael eu hysbysu ac wedi cael cynnig cymorth. Roedd y cymorth hwnnw'n cynnwys canllawiau ynghylch monitro eu materion ariannol; dros y ffôn, e-bost a sesiynau galw heibio; a mynediad rhad ac am ddim at wasanaeth Experian i ymchwilio i statws credyd am ddwy flynedd. Mae byrddau ac ymddiriedolaethau iechyd hefyd wedi tawelu meddyliau staff na chafodd eu heffeithio gan yr ymosodiad, ond a oedd efallai'n poeni am hynny.
Firstly, I can confirm that all identified affected NHS Wales staff have been notified and offered support. The support included guidance on monitoring their financial affairs; via telephone, email and drop-in sessions; and, free access to the Experian credit check service for two years. Health boards and trusts have also provided assurance to staff who were not affected by the breach, but who may have been concerned that they were.
