Stephen Donnelly (Wicklow, Fianna Fail) | Oireachtas source

What I can tell the Deputy is that we have had several reasonably extensive and technical briefings and there has been nothing in any of the briefings I have seen that has suggested additional attacks continued.

It is worth saying, though, that the experts made the point repeatedly that the systems, including the HSE systems, the Department of Health systems and numerous other systems, both public sector and private sector, around the country - our healthcare infrastructure - are the subject of ongoing attack. These attacks to date have been successfully repelled but, obviously, in this case with the HSE, that was not the case.
