I thank Dr. Browne for his attendance. He has given a comprehensive opening statement and his answers have provided some element of extra information and put it in the public domain.

There have been a couple of publicised cyberattacks over the past while. Dr. Browne dealt with the HSE attack and with the Rehab scenario. There was also talk of an attempt on RTÉ. I believe it was one of those simple enough Trojan horse efforts, as in a physical Trojan horse in the form of a USB, and it was caught. I presume the NCSC is looking on these as criminal attacks but on the relationship that exists in Russia between hackers who may operate virtually as subcontractors and this greater level of scanning activity, Dr. Browne already has said that there are contingency plans for all of this. We know that when this initially heated up, instructions had been given out to the critical infrastructure operators that the centre covers. I imagine that these have been updated as the situation has become more serious. I appreciate that our witnesses cannot go into detail on what these contingency plans are in an escalation. Can I start by asking Dr. Browne about those attacks in the first instance and the ransomware scenario?
