Just weeks after the high-profile cyberattack on Marks & Spencer, another UK business has fallen victim to a serious ransomware incident. Peter Green Chilled, a logistics company that supplies major supermarkets including Tesco, Aldi, and Sainsbury’s, has experienced a major system disruption caused by threat actors encrypting company data and halting operations.
A Blow to the Tesco & Aldi Supply Chain
According to a report from the BBC, the company confirmed the attack via an internal email, stating it was dealing with a ransomware incident. These attacks are typically designed to lock businesses out of their critical data, with cybercriminals demanding a ransom payment in exchange for a decryption key.
For a logistics provider like Peter Green Chilled, such an event is more than an IT issue—it’s a direct hit to the supply chain for retailers like Tesco. Disruptions in delivery schedules can lead to stock shortages and ripple effects throughout the retail sector, impacting both suppliers and customers alike.
Expert Insight: A Dangerous Trend
This incident is the latest in a string of cyberattacks against UK retailers. Marks & Spencer, Harrods, and Co-op have all recently faced breaches. M&S in particular has been grappling with severe system issues, with the attack reportedly costing the company over £60 million in lost profits. The financial fallout extended to the stock market too—M&S’s valuation reportedly dropped by over £1 billion.
The breach at M&S is believed to have stemmed from compromised credentials belonging to employees of Tata Consultancy Services (TCS), one of its third-party partners. This underlines the risks posed by third-party access, a frequent vulnerability in modern supply chain networks.
Who’s Behind These Retailer Attacks?
A cybercriminal group known as Scattered Spider is suspected to be behind multiple recent attacks, including the one on M&S. The group is known for its highly sophisticated social engineering tactics, including impersonating IT helpdesk workers.
Law enforcement agencies are catching up, however. Several individuals linked to Scattered Spider have been indicted, and arrests have been made—including a UK national apprehended in Spain last year.
Final Thoughts
The attack on Peter Green Chilled serves as yet another reminder that cybersecurity is no longer a back-office concern. For businesses operating in sectors like logistics and retail, where uptime is critical, even a short disruption can cause significant operational and financial damage.
Proactive cybersecurity measures, employee awareness training, and robust third-party risk management have never been more essential. As threat actors evolve, so too must the security strategies of UK businesses.
