M&S hackers believed to have gained access through third party

  • Marks & Spencer and Co-op suffered cyberattacks in early May 2025 that disrupted systems and led to stolen customer personal data in the UK.
  • Attackers accessed M&S systems through social-engineering targeting a third-party contractor, remaining undetected inside for over two days.
  • Hackers deployed ransomware linked to DragonForce and Scattered Spider groups, compromising names, addresses, dates of birth, and order histories but not complete payment card details.
  • M&S confirmed nearly 9.4 million customer records were affected, assuring no usable card or login details were stolen and urging password resets and multifactor authentication.
  • The attacks caused stock shortages, paused deliveries, and financial losses estimated above £40 million weekly, with companies and authorities working on recovery amid warnings of continued retail cyber risks.
