The recent cyber attacks Against Markings and Spencer (M&S) And The supermarket cooperative are combined into one incident by a large British research group.
The Cyber Monitoring Center (CMC), an independent, non -profit organization that was established to categorize large cyber events by the insurance sector, has stated that it deals with the two incidents as one event by the same attacker – spread spider.
“Given that a threat actor claimed the responsibility for both M&S and Co-op, the narrow timing and the comparable tactics, techniques and procedures (TTPs), CMC has assessed the incidents as a single combined cyber event,” the CMC, “the CMC,” the CMC, ” said.
Combined attack
The CMC says that it has categorized the attacks as a “systemic category 2 event” and estimated that the security surcharges will have a total financial impact of between £ 270 million to £ 440 million ($ 363 million to $ 592 million) on the two companies.
It added that the effects of the attacks were classified as “narrow and deep”, with “important implications”, not only for the two retailers, but also their suppliers, partners and service providers.
In contrast to “superficial and broad” events such as the Crowdstrike incident from 2024, this definition is, which struck a large number of companies in the economy, but the impact for a company was much smaller.
“Although both intended companies are enterprising, data loss and costs for incident response and reconstruction, the vast majority of financial costs stimulate,” the CMC added.
“Most estimated disturbance costs are confronted with the two companies, but our analysis is intended to estimate the broader costs for partners, suppliers and others.”
Although it happens around the same time, the CMC said that the cyber attack on Harrods, another large British retailer, will not be included at this stage, with reference to a lack of sufficient information available about the cause and impact.
M&S was apparently hit by the attack on April 22 and revealed the news of the incident a few days later. The cooperative unveiled the news about his event on April 30 and said that it was forced to pay parts of his IT systems in an attempt to reduce the effects.
M&S has predicted that the attack could cost him around £ 300 million in lost operating result in his financial year.
M&S has not confirmed whether it has paid a ransom to the hackers, but has assigned one Customer data has been stolen in the attack. This contained no passwords or card or payment details, but home addresses, telephone numbers and birth dates may be influenced.
