Former NCSC chief Ciaran Martin pinpoints critical national infrastructure (CNI) as the next big ransomware target

In February 2020, as the spectre of COVID-19 loomed large, Ciaran Martin, then the main govt of the UK’s National Cyber Security Centre (NCSC), spoke along with his US counterpart, Chris Krebs, at a security meeting in Munich.  

During this discussion, the “early warning signs” of a coming ransomware storm lingered in the back again of their minds, he tells IT Pro. Each noticed the rumblings of an impending wave and have been keen to emphasise the necessity to deal with this oncoming danger.  

“It was practically like the commence of a volcanic eruption,” he recalls. We had been the two extremely involved about it and had been expressing that we seriously need to try and do as significantly as we can to restrict this danger. But obviously, a thirty day period later on, the entire world locks alone down thanks to COVID-19.”  

Martin served as the founding main govt of the NCSC from its launch in 2016 right up until mid-2020. Since leaving the establishment, he’s joined the University of Oxford’s Blavatnik College of Authorities, and in January was appointed as director of the Sans Institute’s CISO Network for EMEA, participating in a critical purpose in bridging the gap between field stakeholders and federal government.  

The common world wide change to distant functioning that COVID-19 activated presented issues for security practitioners, organisations, and governments globally, Martin proceeds. In the a few several years considering that, the world wide menace landscape has developed drastically amidst the emergence of remarkably able, subtle cyber criminal offense groups and condition-sponsored threat actors.  

The shifting experience of ransomware

2021 was, by all accounts, the worst 12 months on history for ransomware – and cyber threats additional broadly speaking.  Analysis from AAG discovered far more than 623 million ransomware attacks have been recorded throughout the world that calendar year, marking a 105% raise towards 2020. In the same way, AAG identified additional than one-third of organisations globally endured an attempted ransomware attack.  

Though the danger landscape has ‘mellowed’ to some extent, with ransomware attacks reducing in latest months, Martin admits there are even now really serious warning signals that shouldn’t be ignored. For instance, attacks towards critical countrywide infrastructure (CNI) and community expert services are even now everpresent, he thinks.  

Earlier this month, the FBI printed its 2022 Internet Crime Report, which highlighted the lingering danger of cyber attacks against CNI organisations throughout the final yr. The bureau exposed it gained 870 notices from CNI organisations impacted by ransomware, with 3 of the leading ransomware groups – LockBit, Hive and ALPHV/BlackCat – linked to 350 attacks. 

Offered the arms-on mastering expertise of attacks these types of as the Colonial Pipeline incident, Martin states that the environment requirements to sharpen its focus on cyber resilience to assure the following ‘big hitter’ can be repulsed or far better managed by authorities.  

“I feel there are crucial lessons to learn from, particularly in terms of resilience,” he states. “We’ve often normally considered ‘resilience’ as hard plant infrastructure. But I believe submit-pandemic with the ransomware boost, we are starting off to imagine about cyber resilience in a ‘usefully mundane’ way.

“Every organisation, no subject what they do, ought to be wondering about ransomware. If you have got a pc network, there is a significant risk you’re heading to eliminate it at some issue,” he adds. “It could be an accident, an IT configuration error, or it could be criminals coming in and demanding dollars. It’s about truly asking what does dropping your network indicate to you?” 

How ransomware operators can choose out CNI

Martin is eager to emphasize the Colonial Pipeline incident as a key illustration of how quickly an organisation can be compromised by non-linear attack methods, which he believes raises issues about the basic safety of broader CNI.  

“What Colonial Pipeline showed us is that an ordinary commoner backyard ransomware attack can actually just take out the pipeline with no touching the pipeline,” he suggests.  

“It didn’t jump from the company program into the pipeline. It messed up the company’s skill to organise alone so a lot that it pressured them to make the conclusion to shut down the pipeline since they could not function it properly. 

“Critical capabilities can be severely disrupted devoid of attacking the critical functions, but just attacking the matters that assist you operate them, which have a tendency to be a lot less properly safeguarded.” 

With this in head, seeking in advance, Martin implies it is not out of the concern for a identical circumstance to unfold in just essential critical industries in the UK.  

Just take the national rail network, for illustration. Talking in a hypothetical sense, Martin notes to wreak havoc on the country’s transportation infrastructure, menace actors could conduct an attack in a similar fashion. No direct attack on infrastructure would be required, just the essential qualifications functions that make the network tick.  

“Going and getting out the full signalling infrastructure, for illustration, would be extremely difficult from a specialized perspective. You’d need a very refined operation, experience, time, money, and a degree of luck,” he claims. “But just deleting timetables, or personnel rosters, or halting men and women from paying suppliers or staff members could result in main disruption. That is what problems me.” 

We’ve noticed identical predicaments like this engage in out in the previous, Martin notes, specifically with the attack on the Irish health care process in Could 2021.  

“Did a one piece of medical center machines fail? No. It was fine. No working theatres have been losing electric power or any horror stories about devices failing mid-procedure,” he proceeds. “What happened is that owing to ransomware, the booking method that explained ‘you’re heading to this hospital to see this doctor’ was disrupted. And, of course, that experienced a massive harmful result on healthcare.”  

Horizon scanning to long term-evidence against CNI attacks

Looking ahead, Martin suggests that horizon scanning by the relevant authorities will be key to ensuring the following key attack can be thwarted. This is an spot he’s keen to praise the US and UK governments for – both of those of which have made substantial strides in protecting a vigilant posture amidst a troubling period of time.  

“The UK has finished a decent career with horizon scanning for threats,” he claims. “As have the Us citizens. They’ve introduced a program which is analogous to what comes about in air targeted traffic accidents where by if you have a in the vicinity of-overlook or an accident, it triggers a formal critique.” 

Before this thirty day period, the Biden administration unveiled the National Cybersecurity Method – and CNI was a critical focal position in this announcement. The cyber system touted the creation of least security requirements for CNI operators, in addition to nearer alignment amongst federal companies to issue early warnings for security threats.  

“I imagine the US tactic is really great,” Martin suggests. “Especially in conditions of CNI requiring these least criteria, but also placing obligations on software program suppliers establishing code. On the UK,” he provides, “I’m generally in favour of the recent course of government policy and the way this is doing the job at present.”  

‘Defenders get a vote’ 

Crucially, Martin maintains a good outlook for 2023 and further than. The previous 3 decades have tested that organisations and governments globally can contend with evolving threats and risk, he believes.  

The war in Ukraine showcases this, Martin notes. In the months preceding the invasion, hyperbolic conversations over a veritable cyber onslaught on the West were being commonplace and, while this failed to thoroughly materialise, the incidents that did occur have been relatively contained.  

“Paul Chichester, director of operations at the NCSC, said that a important lesson of Ukraine is that ‘defenders get a vote’ – I believe that is a great outlook,” he says.  

“In other terms, of course, there is a lot of frightening events likely on out there, with a ton of hoopla and dread and an dreadful great deal of risk. But let us not slide into the entice of mistaking that for powerlessness and take note having any agency or decision. We have a vote. There are loads of issues we can do to shield against cyber attacks. And whilst we’re not heading to be in a position to afford to pay for or have time to do all of these, we have a option. I imagine there are grounds for optimism in this article.”
