What a mess this has been. I’ve been buying stuff at M&S since I was knee-high to a grasshopper. This cyber-attack chaos was like watching a car crash in slow motion. The cyber-attack’s impact on M&S sales has been devastating. Left me gobsmacked at how vulnerable our favourite high street stores are.
When the Lights Went Out
Picture this: you’re attempting to purchase your weekly Percy Pigs on the internet. Suddenly, everything’s gone Pete Tong. Just as well when Scattered Spider, an awesome name for a hacking group, chose to hack M&S in April 2025. It was a sophisticated enough attack that it effectively brought the entire operation to a halt.
That first weekend the attack hit, I stopped at my local M&S. The shelves appeared to have been attacked by locusts. Fresh food aisles were almost empty. The staff looked completely frazzled. One checkout woman said they couldn’t even properly process returns because their systems were all wonky.
The Numbers Don’t Lie
The financial carnage has been mental. This “sophisticated and highly disruptive” attack will erase nearly a third of M&S’s full-year profits. We’re talking about a profit hit of 300 million pounds. That’s enough cash to purchase every Percy Pig in the country for the next decade!
The share price took a proper nosedive. Marks & Spencer has lost over 700 million pounds of its market value. Share price fell 6.5 per cent. That’s the sort of drop that should make shareholders reach for the tissues.
Their clothing and homewares divisions are losing £25 million a week. Online shopping makes up about a third of their non-food business. You can see why this has been a proper nightmare.
Personal Shopping Chaos
I have been shopping with M&S for two decades. I’ve witnessed my fair share of shopping hiccups, but nothing like this. The week after the attack, I attempted to order some basics on the internet. You know, the standard stuff, like their cotton shirts and some food basics. Fat chance! (When it wasn’t that, the site was either completely down or running as fast as a bucket of molasses.)
What got my goat was trying to use their click-and-collect service. I had just put in an order when the attack came. It had been hung in digital limbo for weeks. The customer service reps, bless their hearts, were doing their best. They had one hand tied behind their back, however.
The Domino Effect
The knock-on effects have been barmy. When the shelves were empty, so were the aisles, and customers like me went elsewhere for their groceries. Tesco, Sainsbury’s, John Lewis. After you succeed in shopping somewhere else, there’s always the question: why go back? That’s the genuine long-term concern for M&S.
I spoke with a mate of mine who works in retail analytics. She figures the customer acquisition cost to win back shoppers will be huge. It is one thing to see sales plummet during the attack. Then you risk losing the loyalty of the customer. That’s the gift that just keeps on giving, or rather, taking away.
Recovery Road
M&S restored its website on the evening of May 21. Read-only mode only, though. Projections indicate that online sales disruptions will persist until July. That’s months of lost revenue and frustrated customers. I was finally able to make an online purchase in late June. The whole thing was clunky and slow.
The company has been unusually mum about the details. Reasonable, all things considered, I guess. But as a customer, the poor communication was honestly irritating. You’re left to ponder whether your data has been nicked. If your orders will ever show up. Is it safe to shop there again?

The Human Cost
But beyond the financial hit, there was a real human element to this story. Store employees worked round the clock to handle the chaos that wasn’t their doing. And supply chain workers have been hustling to get products moving through alternative options.
M&S staff members appear to be more stressed than usual these days. Can’t blame them really. Dealing with people who are pissed off because your systems are knackered is not a piece of cake. They must have been giving the poor sods on the customer service phones an absolute earful day in and day out.
Lessons Learned the Hard Way
This is an attack that could have been avoided with improved security procedures. Scattered Spider is no brand-new menace. They’ve been causing chaos for years. The very fact that they were able to penetrate the M&S systems so effectively implies some major holes in their cybersecurity planning.
The wider implications of the M&S cyber-attack on sales are not just purely financial. It’s damaged trust. Disrupted supply chains. Shown competitors exactly where M&S vulnerabilities lie. That’s market intelligence worth its weight in gold to competing retailers.
For 15 years, I’ve been in tech. Seen plenty of security breaches. This one is distinctive because of how entirely it shut down operations. Most attacks fall on a single system or a single department. This was total carnage.
What My Neighbours Think
So the other day, I was talking to my neighbour over the garden fence. She has been an M&S customer for 40 years. Even she does her weekly shop at Waitrose now. “Can’t be doing with all that digital nonsense,” she said. “If they can’t protect their computers, how can I trust them with my money?”
That conversation hit home. When you start losing her kind of customer, who is truly loyal and a long-time shopper, you know you have a colossal problem.
Looking Forward
M&S will bounce back eventually. They’re too much of a British institution to disappear entirely. This attack, though, has revealed just how fragile our digital shopping infrastructure truly is. Recovery goes beyond repairing computers. It’s about rebuilding customer confidence.
The lad who delivers my groceries works for one of M&S’s competitors. He said elsewhere in town, their delivery slots have been solidly booked in the wake of the attack. Among those who switched, virtually none will switch back to the old guys anytime soon. It’s the true kicker for M&S.
What worries me most is that this won’t be the last attack we see. If hackers can bring down M&S, they can probably target any major retailer. That’s a sobering thought for anyone who does their weekly shop online.
The Bottom Line
The financial havoc is evident, but the reputational fallout could take years to assess in full force. I’ve been shopping there for decades. Hope they’ve learnt their lesson and paid for good cyber security. Because the next time, we might not be so lucky.
This entire ordeal has taught me one thing: it’s not such a terrible idea to carry some cash in your wallet after all. When the digital world goes tits up, the old-fashioned money still does the trick!
