The Growing Ransomware Crisis

The recent cyber attacks aimed at Marks & Spencer, the Co-op and Harrods have been in the news, but this is not just an issue for retailers, as hackers strike almost any firm, in any line of business, at any time and anywhere in the world. 

The reality for business leaders, and for investors, is that the risk is practically universal. FTSE 100 CEOs and entrepreneurs running small firms are living in fear that they will be next.

Cyber attacks have cost UK companies £44 billion in lost revenue over the past five years and have affected around 52% of firms. 

Some have called in former hostage negotiators, skilled in dealing with blackmailers and terrorists. Others have claimed on their insurance policies to pay ransom demands, fuelling concerns that the very existence of such cover encourages the criminal gangs. It seems that persistent criminals have no difficulty to find a way in through gaps in a company's cyber defences, such as the IT systems and serviced from a supplier. 

A hacking gang known as Scattered Spider has been attributed  responsibility for the attacks on Marks & Spencer  (M&S), Co-op and Harrods. The criminals that were involved launched the devastating assault over the Easter bank holiday, with serious and ongoing consequences for M&S. Senior management at M&S were reluctant to pay a ransom, as and when demands were made. Typically, this happens via the Dark Web and hackers demand payment in crypto currency. 

Experts have suggested that M&S exploit, now in its third week, is a classic 'ransomware' attack, where data systems are infiltrated, disabled and only unfrozen when a ransom is paid.

Customers have been unable to place orders via its website and app, warehouse staff have been sent home and the retailer's popular click-and-collect service remains suspended, though contactless payments in store have been restored. Even recruitment has been paused as fears grow that the cyber crisis could take months to resolve.
There are concerns that working from home could be a risk factor. According to M&S's latest annual report: 'The sophistication and frequency of cyber-attacks continue to increase' as the company operates 'a hybrid work model'.

Outsourcing IT by using contractors is also an issue. 'Our reliance on key third parties for selected services and/or hosting of data also exposes us to risks from vulnerabilities in their cyber and data controls.' M&S said in a statement.

  • The Co-op has admitted that hackers had been able to access a 'significant number' of its customers' personal data, including names and addresses, but not passwords or financial information such as credit card details of its 6.2 million members.
  • In November last year Co-op's rival Morrisons was hit by hackers who targeted its warehouse technology supplier Blue Yonder
  • The NHS, the Guardian newspaper and the British Library have also been subject to ransomware attacks, causing serious short-term disruption to their systems. In some cases, the damage is fatal.
  • Foreign exchange firm Travelex collapsed six months after a ransomware attack at the end of 2019. Administrators cited the incident as a key factor.

A recent British Government Report says that, 'For the serious and organised crime gangs behind the global fraud industry, ransomware is an increasingly lucrative part of their operations.' Ransomware attacks on UK firms 'significantly increased between 2024 and 2025', the report concludes, with an estimated 19,000 companies falling victim to a ransomware attack over that period. 

The UK National Cyber Security Centre (NCSC) reports that  76 per cent of UK businesses experienced a cyber security incident in the past year. Most were from lower-level 'phishing' attacks, where fake emails or websites are used to gain access to a user's password or credit card details to steal money.

The impact of ransomware attacks can be devastating and only 4% of organisations that pay-up recover all their data, and many take months to recover. The damaging consequence of an attack include:-

  • Financial Losses: Ransom demands can range from tens of thousands to millions of dollars or pounds. Even if the ransom is paid, the cost of recovery and disruption can be significant. 
  • Operational Disruptions: Ransomware can render systems unusable, leading to downtime and delays in business operations. 
  • Reputational Damage: A successful ransomware attack can damage a company's reputation and erode customer trust. 
  • Data Breaches: Ransomware attacks can expose sensitive data, leading to legal and financial liabilities. 

A critical question is whether companies are employing enough C level executives with sufficient expertise in cyber resilience field. The problem is that, however hard a business tries to secure its systems, it has to be watertight all of the time, whereas the hackers need only be lucky once.
