For orgs looking for defence tips for the attacks on UK retailers, this blog from 2022 about the UK teenagers in LAPSUS$ has relevance.
As a plot twist - not documented anywhere online, but LAPSUS$ first attacks in 2021 were against UK high street retailers.
For anybody wondering what 'dial into the incident response bridge' means, it means they'll literally Teams call into cyber IR bridges as themselves and just extort you to your face. They'll also call CISOs etc. Bad Times at the El Royale.
Marks & Spencer bureau de change staff are being forced to use pen and paper to serve customers as a result of the cyber attack on the retailer and cannot accept card payment. https://www.thisismoney.co.uk/money/markets/article-14696595/Hack-rocks-Marks-Spencer-bureau-change.html
Co-op Group have provided some more detail about what it’s doing about remote lifeline stores (ones where they’re the main/only retailer on an island):
“From Monday, 12 of the most remote lifeline stores will receive treble the volume of available product, and another 20 lifeline stores will get double the volume.” https://www.bbc.com/news/articles/c071e7x80djo
DragonForce Ransomware Cartel’s portal is back online after a multi week outage. No sign of M&S or Co-op’s data.
All M&S recruitment is still stopped, 19 days in. https://jobs.marksandspencer.com/
I think Co-op may have stopped recruitment too, they’re a big employer so usually have hundreds of open positions - currently they have 17, and most close today and the rest in a few days.
The Record quotes a Co-op worker as saying they are operating at well below 20% of their normal capacity in depots. https://therecord.media/co-op-cyberattack-uk-company-fears-hackers-still-in-system
Allianz supplies Marks and Spencer's cyber insurance, and will apparently suffer a full tower loss (i.e. it's going to be expensive) https://www.insuranceinsider.com/article/2esiwg4yv6p38pcf2pgxs/lines-of-business/cyber/allianz-leads-cyber-cover-for-m-s-ransomware-attack
People in Machynlleth are apparently turning up at local farms in search of food due to lack of produce at Co-op https://www.cambrian-news.co.uk/news/cyber-attack-people-turning-up-at-farms-as-machynlleth-co-op-shelves-remain-bare-792434
Co-op stores in Sheffield, Badenoch, Dunfermline and many other places are apparently running out of produce - it's not possible to keep up with the local media reports but they're basically bored reporters get sent out to photograph half empty fridges.
This ITV News report linking the Co-op and M&S breaches to SIM swapping is not accurate, no source given. https://www.itv.com/news/2025-05-12/sim-swap-fraud-rises-by-1000-as-criminals-exploit-two-factor-authentication
They also have a report today saying Co-op stores are restocked, which is also not accurate - that one is sourced from Co-op, but obviously doesn’t stack up to looking in Co-op stores.
If anybody is wondering, all of Marks and Spencer's Palo-Alto GlobalProtect VPN boxes are still offline, 3 weeks later. Pretty good containment method to keep attackers out.
Co-op's VDE environment is still down, too.

M&S confirm my toot from 3 days ago that a significant amount of customer and staff data was stolen. They’ve known for weeks but opted not to tell anybody. https://www.bbc.com/news/articles/c62v34zv828o
@GossiTheDog I can only hope this data breach is the kick up the arse needed to abolish the common practice of using date of birth as an (immutable!) security password. Once it’s public knowledge it’s beyond useless… it’s a liability. Especially in banks.
I will not be holding my breath on this one.
Re the Co-op Group breach, Co-op say home addresses of customers were exfiltrated (it was the membership database). This one dates back to my May 2nd toot upthread re home addresses - at the time, they didn't specify home addresses.
Co-op Group have 5 open jobs left, with nothing posted for 11 days.
Co-op's AGM is this weekend, and M&S yearly results and investor contact are next week.
Gonna be awkward for different reasons, e.g. Co-op is member (customer) owned, so the people's data Co-op had stolen are effectively the shareholders and are invited.
The Channel Islands Coop, which is different to Co-op Group, has been able to restock shelves by moving away from Co-op Group for supply distribution and moving to local suppliers. https://www.bbc.co.uk/news/articles/c3d4xvg3x1do
The Grocer reports Nisa and Costcutter are running out of fruit & veg, fresh meat and poultry, dairy products, chilled ready meals, snacks and desserts.
Nisa and Costcutter are supplied by Co-op Wholesale, which is dependent on Co-op Group.
“It’s really poor. I feel bad for them but what makes it worse is their hush-hush mentality about it. There’s no proper level of communication and we get random updates.”
Co-op Wholesale claim there are no problems. https://www.thegrocer.co.uk/news/nisa-and-costcutter-hit-by-stock-shortages-amid-co-op-cyberattack/704393.article
A look at supplies in stores today, after Co-op told ITV yesterday that stores were restocked 😅
Co-op Group have told their suppliers that "systemic-based orders will resume for ambient, fresh, and frozen products commencing Wednesday 14 May". They say forecasting system will still be impacted.
https://www.thegrocer.co.uk/news/co-op-to-get-systems-back-on-track-after-cyberattack/704425.article
Harrods say they are not asking customers to do anything differently at this point.
Financial Times report Marks and Spencer expect to claim £100m on their cyber insurance, the maximum allowed, suggesting losses probably more. https://www.ft.com/content/723b6195-1ce7-4b5f-94f5-729e9152c578
Co-op Group say they have exited containment and begun recovery phase https://www.theguardian.com/business/2025/may/14/co-op-cyber-attack-stock-availability-in-stores-will-not-improve-until-weekend
Marks and Spencer are still in containment
If you want figures for your board to set expectations in big game ransomware incidents, Co-op containment just over 2 weeks, M&S just over 3 weeks so far - recovery comes after.
In terms of external assistance, Co-op have Microsoft Incident Response (DART), KPMG and crisis comms. M&S have CrowdStrike, Microsoft, Fenix and crisis comms.
The threat actor at Co-op says Co-op shut systems down, which appears to have really pissed off the threat actor. This was the right, and smart, thing to do.
While I was at Co-op we did a rehearsal of ransomware deployment on point of sale devices with the retail team, and the outcome was a business ending event due to the inability to take payments for a prolonged period of time. So early intervention with containment was the right thing to do, 100%.
Co-op Group recruitment looks like it is starting again, first new roles in two weeks posted. https://hcnq.fa.em2.oraclecloud.com/hcmUI/CandidateExperience/en/sites/CX/jobs
Marks and Spencer say food distribution to their stores is returning to normal. It follows Co-op's announcement yesterday that food and drink distribution will begin to return to normal from the weekend. https://www.reuters.com/business/retail-consumer/uks-ms-says-food-availability-improving-every-day-2025-05-15/
27 new jobs at Co-op added today, and it's only midday. So recruitment was definitely paused for two weeks and now active again.
M&S have finally told staff that data about themselves was stolen: https://www.telegraph.co.uk/business/2025/05/16/ms-staff-data-stolen-by-hackers-in-cyber-attack/
You may notice I said they had staff data stolen on May 9th in this thread.
For the record, the tools listed in this article aren't used by Co-op.
The link in the article to Vectra Cognito AI has a Coop Sweden logo on it, and the Coop Sweden CISO is named. Coop Sweden is different company. Coop Sweden went on to have a ransomware attack that crippled the org, including point of sale, so I don't think it's a good sales point. Same with Silverfort.
Google AI has ingested the article and now uses it to claim Co-op Group use the tools.
M&S recruitment is still fully stopped, almost a month in. Co-op opened 46 new vacancies today.
Marks and Spencer’s CEO will lose a £1.1m share grant as a result of their cyber incident. https://www.ft.com/content/43531d25-4f7a-4d6e-b809-e85bb8f0033e
The Times reports M&S were breached through a contractor and that human error is to blame. (Both M&S and Co-op use TCS for their IT Service Desk).
The threat actor went undetected for 52 hours. (I suspect detection was when their ESXi cluster got encrypted).
M&S have told the Times they had no “direct” communication with DragonForce, which is code for they’re using a third party to negotiate - standard practice.
https://www.thetimes.com/uk/technology-uk/article/m-and-s-boss-cyber-attack-7d9hvk6ds
M&S looks to be moving to reposition their incident as a third party failure, which I imagine will help redirect some of the blame (they present their financial results during the week to investors): https://www.bbc.co.uk/news/articles/cpqe213vw3po
Both M&S and Co-op outsourced their IT, including their Service Desk (helpdesk), to TCS (Tata) around 2018, as part of cost savings.
There's nothing to suggest TCS itself have a breach btw.
Basically, if you go for the lowest cost helpdesk - you might want to follow the NCSC advice on authenticating password and MFA token resets.
I've put a 3 part deep dive blog series coming out probably next week called Living-Off-The-Company, which is about how teenagers have realised large orgs have outsourced to MSPs who follow the same format of SOP documentation, use of cloud services etc. Orgs have introduced commonality to surf.
The Office of the Privacy Commissioner for Personal Data (PCPD) has confirmed that Marks and Spencer (M&S) Hong Kong has not informed it of a recent customer data leak, nor responded to its enquiries. https://hongkongfp.com/2025/05/19/ms-hong-kong-not-responding-to-privacy-commissioners-office-after-online-customer-data-breach/
"Cyber analysts and retail executives said the company had been the victim of a ransomware attack, had refused to pay - following government advice - and was working to reinstall all of its computer systems."
Not sure who those analysts are, but since DragonForce haven't released any data and M&S won't comment other than to say they haven't had any "direct" contact with DragonForce, I wouldn't make that assumption.
There's also a line in the article from an cyber industry person saying "if it can happen to M&S, it can happen to anyone" - it's ridiculous and defeatist given Marks and Spencer haven't shared any technical information about how it happened, other than to tell The Sunday Times it was "human error"
The Air Safety version of cyber industry would be a plane crashing into 14 other planes, and industry air safety people going "Gosh, if that can happen to British Airways it could happen to anybody!"
Tomorrow it’s one month since Marks and Spencer started containment, it’s also their financial results day.
Online ordering still down, all recruitment stopped, Palo-Alto VPNs still offline.
TCS have been linked to the Marks and Spencer breach, at least in part.
I made this point a few weeks ago, but... outsourcing all your IT, Networks, Service Desk (helpdesk) and operational cybersecurity is a temporary cost saving and basically paints a ticking timebomb on the org, IMHO.
@GossiTheDog I must admit to not being particularly enamoured by the overall concept of third party identity security services.
M&S say online ordering will be stopped until sometime in July, and it has taken a £300m hit, far higher than analysts had predicted. https://www.bbc.co.uk/news/articles/c93llkg4n51o
Their CEO has commented they’ve drawn a line under the hack, without recovering, which has a bit of this energy honestly
The NCA has confirmed on the record that the investigation into the M&S and Co-op hack is focused on English teenagers. I could toot the names of the people I think they’ll pick up, but won’t.
https://www.bbc.co.uk/news/articles/ckgnndrgxv3o
The CEO of M&S has declined to comment if they have paid a ransom. For the record: I’ve heard they have, in secret, via their insurance. https://www.reuters.com/business/retail-consumer/ms-says-cyber-attack-was-result-human-error-declines-comment-ransom-2025-05-21/
Co-op Group announces it's getting rid of paper prices in stores, going to electric displays. Good luck during a ransomware incident 😒
TCS has a security incident running around the M&S breach.
Interestingly the source claims TCS aren't involved in Co-op's IT - which is categorically false, they took over most of it while I worked there, including the helpdesk, and my team (SecOps) after I left.
https://www.ft.com/content/c658645d-289d-49ee-bc1d-241c651516b0
Insurance Insider say Co-op Group have no cyber insurance policy.
It’s got the insurance industry hard as they think they can ambulance chase other orgs with it.
Seven weeks in, Marks and Spencer still have recruitment closed, online orders stopped and no Palo-Alto GlobalProtect VPN.
While Co-op have restored every customer facing system and internal systems like recruitment and remote working, M&S still don't even have recruitment back.
I'm reliably told they paid the ransom, so they'll be target #1 basically forever with other ransomware groups now due to resiliency woes and willingness to pay.
