A combined physical and cyberattack<\/a> on a critical electricity transformer would cause \u201cgrid collapse\u201d within two hours, impact critical services within six hours, and threaten \u201csocial collapse\u201d in just 48 hours, according to experts from the Defence Forces<\/a>.<\/p>\n

A team of engineers and air corps officers told managers of State utilities and engineers working in critical infrastructure that these timelines were based on a \u201cplausible, evidence-based\u201d hybrid attack.<\/p>\n

In a series of presentations at a special Engineers Ireland event, entitled \u2018Security of Critical National Infrastructure’, the Defence Forces experts said it was \u201clikely\u201d that adversaries have already conducted an intelligence operation identifying vulnerabilities in Ireland\u2019s electricity grid and other critical sectors.<\/p>\n

\u201cThey may already have more information about your infrastructure than perhaps your own management board,\u201d Lieutenant Kieran White told attendees.<\/p>\n

\u201cThe HSE is proof that Ireland is already seen as a target,\u201d he said, referring to the crippling cyber incident in 2021. \u201cThe HSE cyberattack happened; the hybrid blueprint you have seen today has not \u2014 yet.\u201d\u00a0<\/p>\n

The event also heard other examples of vulnerabilities in, and threats to, Ireland\u2019s critical national infrastructure.<\/p>\n

The event heard:<\/p>\n

Ireland\u2019s three major ports have very narrow entry points \u2014 150m-200m wide \u2014 and, if a ship sank, food supplies would be disrupted within three days and oil supplies would become critical within three weeks.
\n Transport systems are a \u201csoft underbelly\u201d, and just a \u201cpair of pliers\u201d is needed to open up transport cabinets on city streets and gain access to transport networks.
\n Drone surveillance of critical infrastructure is not covered in Irish laws, unlike in Britain, and drones can carry out infra-red imaging of a substation from outside a perimeter area.
\n Russian ‘shadow vessels’ represent a \u201cticking timebomb\u201d both in their threats to sub-sea cables and pipelines and to marine safety, from pollution. Increased military boarding of these vessels by Baltic, Belgian, and French states could \u201cpush\u201d more of them westwards to Irish waters.\u00a0<\/p>\n

Power transformers a ‘critical vulnerability’<\/p>\n

In presentations to engineers, industry bosses, and utility regulators, the Defence Forces\u00a0team detailed threats to the country\u2019s critical national infrastructure, focusing on the electricity grid.<\/p>\n

Mr White said Ireland\u2019s power transformers are a \u201ccritical vulnerability\u201d, not just because they were visible but because the lead time to replace a damaged one was \u201c12 to 24 months\u201d.<\/p>\n

He said previous incidents in the US had shown this was technically possible, both from a physical and cyber perspective.<\/p>\n

\u201cEngineering analysis suggests there are fewer than a dozen high-value sub-stations [in Ireland],\u201d Mr White said. \u201cAn adversary who has mapped this \u2014 and they have \u2014 knows exactly which ones they are.\u201d\u00a0<\/p>\n

He said the Irish grid, using EU standards, is designed to survive the loss of a single element \u201cwithout cascading failures\u201d. But he said it is not designed to withstand multiple simultaneous attacks.<\/p>\n

He gave the following outline of a successful physical and cyberattack on a critical power station:<\/p>\n

T+2h (Two hours after action) – Grid collapse: \u201cRegional or national blackout\u201d, with replacement time of station 12-24 months;
\n T+6h – Critical services hit: Hospital generators have 48-72 hours of fuel; Irish Water pumping stations lose power; communication infrastructure degrades; emergency communications overwhelmed;
\n T+48h \u2013 Social collapse: Water pressure falls across urban areas; food cold chains disrupted; fuel rationing begins; Government authority visibly strained; social media becomes second battle space;
\n T+72h \u2013 Adversary achieves objective: Government credibility damaged; EU Article 5 obligations strained; attack is over, but crisis is not.<\/p>\n

The Department of Defence is expected this week to publish Ireland\u2019s first Critical Entities Strategy, mapping out critical national infrastructure, risks to them, and State responses.<\/p>\n

In a separate presentation, Commander Cathal Power of the naval service said the recent boarding activities of Russian \u2018shadow vessels\u2019 by the Baltic states, France, and Belgium \u201ccould push westwards\u201d, into Irish waters, more of these vessels.<\/p>\n

He said this is where the new enforcement powers, announced by the Government, would \u201cvery much come to the fore\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"A combined physical and cyberattack on a critical electricity transformer would cause \u201cgrid collapse\u201d within two hours, impact…\n","protected":false},"author":2,"featured_media":349122,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[72,29662,13308,61,60],"class_list":["post-349121","post","type-post","status-publish","format-standard","has-post-thumbnail","category-business","tag-business","tag-cybercrime","tag-defence-forces","tag-ie","tag-ireland"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/349121","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=349121"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/349121\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/349122"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=349121"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=349121"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=349121"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
