M&s Cyber Attack Chaos Leaves More Questions Than Answers

It's now been much than a week of chaos for Marks and Spencer (M&S), 1 of nan UK's biggest brands, pursuing what - it is now evident - is simply a important cyber attack.

It's costs nan retailer millions of pounds successful mislaid income and a little stock price.

M&S still isn't revealing precisely what aliases who knocked retired its online ordering systems, paused deliveries, left quiet shelves successful stores, and resulted successful constricted entree to soul platforms ("they're utilizing pen and insubstantial mate," 1 interaction told me).

The patient is moving pinch nan National Cyber Security Centre, which will not remark connected progressive investigations. The Information Commissioner's Office, nan information protection regulator, says it is "making enquiries".

M&S maintains it has nary specifications to stock astir nan incident.

As clip goes on, though, nan chorus of unanswered questions grows louder. Starting with, why is this taking truthful long?

Many non-cyber related method glitches are comparatively speedy fixes. An outage caused by a faulty package aliases server update, aliases moreover personification error, tin often beryllium resolved successful a matter of hours.

But trying to find and extremity malware sweeping done systems and causing havoc connected nan standard of those operated by a ample nationwide retailer for illustration M&S, is not a speedy occupation says Professor Alan Woodward, a cybersecurity master from Surrey University.

"Everything from knowing what has been sold, hence what needs replenishing, to taking paper payments is very limited connected analyzable systems… it will return important clip and expertise to analyse and guarantee they person expelled nan hacker," he said.

Lisa Forte, partner astatine cyber information patient Red Goat, agrees.

"They are handling nan disruption successful a mature measurement but to expect immoderate institution to get thing backmost online successful a week is ne'er going to happen," she says.

"I don't cognize 1 organisation that could do it."

A batch is besides riding connected nan quality of nan threat. The longer a cyber incident goes on, nan much apt it is to beryllium ransomware, opportunity aggregate cybersecurity experts.

"I would propose location is simply a precocious level of assurance this is simply a ransomware style event," says Dan Card, cyber master astatine BCS, nan chartered institute for IT.

"I picture these arsenic for illustration a integer explosive has gone off. So recovering from them is often some technically and logistically challenging… nan unfortunate organisation is apt going to beryllium moving astir nan timepiece to respond and recover."

Ransomware is simply a peculiarly nasty strain of virus, successful which nan proprietor of a machine aliases web of computers is locked out, their information scrambled, and nan attackers request a fee, usually successful cryptocurrency, to reconstruct it.

Official proposal is not to pay. You are, aft all, putting your spot successful criminals to beryllium existent to their word.

But it is often intolerable to reconstruct compromised services without nan hackers' cardinal – meaning nan only measurement astir it is to either usage back-ups aliases instal caller systems and commencement again.

M&S will not comment, and nary attacker has yet gone nationalist pinch immoderate demands – though this doesn't ever happen, it is often a measurement for cyber criminals to heap much unit onto their victims.

As to who those hackers mightiness be: fingers are pointing astatine a alternatively fluid web of individuals called Scattered Spider (it besides has different aliases).

It was down nan onslaught connected the MGM Las Vegas hotels successful 2023.

The website Bleeping Computer cites "multiple sources" suggesting they are responsible and says immoderate of them are teenagers.

Rik Ferguson, typical advisor to Europol's European Cyber Crime Centre, says nan sources of speculation astir nan group's engagement look reliable but adds that he has seen nary conclusive grounds truthful far.

I asked him whether M&S customers should beryllium concerned astir their individual information: nan patient itself presently says nary action is required.

"Only M&S are capable to show america whether customers should beryllium worried astir their individual data," he said.

"In nan absence of certainty, it would beryllium surely beryllium advisable for M&S customers, peculiarly those who whitethorn person reused their M&S relationship credentials connected different web services, to statesman changing those passwords elsewhere."
