I'm going to make this the new ongoing megathread for DragonForce Ransomware Cartel's attack on UK retailers as they're all connected.
Why it matters: these are some of the UK's largest retailers, think Target or some such in a US sense.

The individuals operating under the DragonForce banner are using social engineering for entry.
Defenders should urgently make sure they have read the CISA briefs on Scattered Spider and LAPSUS$ as it's a repeat of the 2022-2023 activity.

Co-op Group have now admitted a significant amount of member (customer) information has been stolen by DragonForce Ransomware Cartel, saying they "accessed data relating to a significant number of our current and past members" - around 20 million people. The Membership database, basically. That includes home addresses and phone numbers etc.
Up until now Co-op hadn't even used the words cyber or threat actor, referring to an "IT issue" and "third party" in comms.

New by me - breaking down the attacks on UK highstreet retailers
-
Regarding IOCs around the UK retailer activity - there’s loads doing the rounds, and they’re almost all not useful.
Eg hundreds of dynamic VPN IPs from 2022. If you google them you’ll find them on vendor blogs from years ago for Scattered Spider - people are recycling in panic and passing around in panic.
Don’t hunt on random IOCs. IP addresses change. Strengthen foundational controls. Review sign in logs for abnormal activity etc.

One of M&S’ biggest suppliers have said they have reverted to pen and paper for orders due to M&S lacking IT.
Additionally, M&S staff are raising concern about how they will be paid due to lack of IT systems.
M&S are over a week into a ransomware incident and still don’t have their online store working.
-
By the way, this is absolutely terrible advice for dealing with a major and high visibility ransomware incident.
-
There's a report on ITV News that Co-op member data is available on the Dark Web(tm), but as far as I know this isn't accurate. DragonForce's portal hasn't been available for over a week.
-
Here's the ITV News report anyhoo, logline: "ITV News understands the the ongoing cyberattack faced by the supermarket has worsened since Friday, impacting the ordering system, drivers and warehouse staff."
-
Sunday Times has a piece looking into ransomware incident at Marks and Spencer. It's pretty good, goes into their contain and eradicate focus.
"By shutting down parts of the IT estate, Higham’s team had worked to prevent the attack from spreading, but had also stopped parts of its digital operations from functioning. This was considered a worthy trade-off."
One error in the article - lack of recovery doesn't mean no ransomware paid. Paying is not quick restoration.

A wrote a piece about paying ransoms does not equal quick restoration - in fact, quite often it makes things worse. https://doublepulsar.com/big-game-ransomware-the-myths-experts-tell-board-members-03d5e1d1c4b7

Great NCSC piece by @ollie_whitehouse
I’d add - block by Entra policy specifically High risk logins (below is too FP prone), and SOC monitor them. SOC playbook = account probably compromised. How?

Sky News quote a source in M&S head office saying Marks and Spencer have no ransomware incident plan so they are making it up as they go along apparently, with staff sleeping in the office and communicating via WhatsApp.
M&S dispute this, saying they have robust business continuity plans.

BBC News has a look at teenagers phoning helpdesks and pretending to be the CISO. https://www.bbc.com/news/articles/c4grn878712o

One of the points of exploitation of large orgs is they usually outsource their Service Desk to somewhere cheap offshore who don’t know the org staff, and when you call and say your name, they normally put big all caps bold red warning if the person is a VIP, eg C suite, so they get VIP service - ie anything goes.
-
Co-op Group appear to be trying to course correct with their cyber incident comms.
They’re calling it a cyber incident now, and have put a statement on the front page of their website, along with an FAQ. They haven’t yet emailed members (they should). Edit: they’ve started emailing members.
-
It sounds like the situation at Co-op has got worse. They’ve stopped taking card payments in some stores, it’s cash only. https://www.telegraph.co.uk/business/2025/05/06/co-op-shops-stop-taking-card-payments-amid-cyber-attack/
