M&S had their ransomware incident communicated via internal email - from the account of a staff member who works for TCS.
The way TCS work is you give them accounts on your AD.
Marks and Spencer have started partial online shopping again.
For statto nerds, around 7 weeks from containment to partial recovery
M&S still have no recruitment system, two months in.
TCS have told shareholders their systems were not compromised in the hack of M&S.
As an explainer here (not in the article): TCS IT systems weren't compromised. Their helpdesk service (they're AD admins at M&S) was used to gain access to M&S. They manage M&S IT systems.

Latest Marks and Spencer update is pretty crazy.
M&S haven't been able to supply sales data - so the British Retail Consortium (BRC) - used by the UK government as as economic indicator - basically made up figures for M&S and didn't tell people they had done this.

Ultra spicy post claiming to be from UK retailer employee (M&S or Co-op) about their experience with TCS on their security incident. https://www.reddit.com/r/cybersecurity/comments/1ll1l6c/scattered_spider_tcs_blame_avoidance/?utm_source=share&utm_medium=mweb3x&utm_name=mweb3xcss&utm_term=1&utm_content=share_button
Marks and Spencer’s CEO says half of their online ordering is still offline after their ransomware incident, they hope to get open in next 4 weeks.
They are also rebuilding internal systems and hope a majority of that will be done by August.
Lesson: mass contain early. M&S didn’t. Co-op did.
17 and two 19 year old teens picked up over Co-op and M&S hacks, and a 20 year old woman.
Pretend to be surprised.
If you ever doubted the link between Scattered Spider(tm) and LAPSUS$ - one of the people arrested today was a key part of the LAPSUS$ attacks a few years ago.
After almost 3 months, Marks and Spencer recruitment system came back online just now. First 4 jobs posted.
. @briankrebs has broken the story that the key member (and teenager) of LAPSUS$ runs Scattered Spider

@GossiTheDog @briankrebs the comments section is, uh, something
Co-op finally admitted the entire membership database was stolen
I had this in the thread months ago, they originally tried to deny it entirely then tried to say ‘some’ data was accessed when they knew it was the whole thing.
Personally I think Co-op did a really good job getting out of that situation and minimising impact.
I definitely think if you have a LAPSUS$ style advanced persistent teenagers situation, tilt towards open and honest comms as those kids will use secrecy against ya. It’s 2025, it’s okay to say you got hacked, people largely understand. Also, in IR, lawyers are usually stuck in 1980 advice - it’s just advice, they ain’t yo boss.
