Ahold Delhaize October 2026 cyberattack disrupts Benelux/US online and supply chain; Q4 sales hit €200–250M · updates https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack On Oct 12 2026 Ahold Delhaize detected a cybersecurity issue in its IT infrastructure and took systems offline as a precaution. Brands' physical stores stayed open, but websites, apps and e-commerce were disrupted across parts of Europe and the United States, along with Benelux supply-chain operations; Bol was not impacted. On Oct 19 the company said the activity was malicious, that it had notified the Dutch NCSC within 24 hours, filed a police report, and had no evidence at that time of sensitive customer, associate or partner data theft. In its Nov 4 Q3 2026 results, Ahold Delhaize estimated the incident will cut Q4 net sales by €200–250 million and underlying/IFRS operating income by €75–100 million, and lowered full-year guidance; CEO Frans Muller said most disruption was contained within two weeks while full restoration continues. Attack type has not been publicly disclosed. Dutch NCSC saw no reason to link this IT outage to the separate European supermarket refrigeration-controller campaign. en Fri, 06 Nov 2026 00:00:00 GMT Ahold Delhaize October 2026 cyberattack disrupts Benelux/US online and supply chain; Q4 sales hit €200–250M: SecurityWeek covers Ahold Delhaize's estimate of the financial toll of the October cyberattack. https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack#2026-11-06-2d76ccaa Fri, 06 Nov 2026 00:00:00 GMT high <p><a href="https://www.securityweek.com/grocery-giant-ahold-delhaize-estimates-financial-toll-of-october-cyberattack/">Source</a></p> Ahold Delhaize October 2026 cyberattack disrupts Benelux/US online and supply chain; Q4 sales hit €200–250M: Q3 results: estimates Q4 net sales reduced by €200–250M and underlying/IFRS operating income by €75–100M due to the October cyberattack; full-year guidance cut; Muller says most disruption contained within two weeks while restoration continues. https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack#2026-11-04-52a60716 Wed, 04 Nov 2026 00:00:00 GMT high <p><a href="https://newsroom.aholddelhaize.com/ahold-delhaize-reports-resilient-q3-2026-results-and-updates-2026-guidance-to-reflect-business-disruption-caused-by-recent-cybersecurity-incident/">Source</a></p> Ahold Delhaize October 2026 cyberattack disrupts Benelux/US online and supply chain; Q4 sales hit €200–250M: Company update: investigation confirms malicious actions; Dutch NCSC notified within 24 hours; formal police report filed; no evidence at that time of sensitive data theft; phased restoration of sites and apps underway. https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack#2026-10-19-77bcdfed Mon, 19 Oct 2026 00:00:00 GMT high <p><a href="https://newsroom.aholddelhaize.com/ahold-delhaize-update-on-status-of-cybersecurity-incident/">Source</a></p> Ahold Delhaize October 2026 cyberattack disrupts Benelux/US online and supply chain; Q4 sales hit €200–250M: Ahold Delhaize says it is experiencing a security issue in its network and takes some systems offline as a precaution; stores remain open. https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack https://pwn.watch/i/ahold-delhaize-october-2026-cyberattack#2026-10-12-91bb99d0 Mon, 12 Oct 2026 00:00:00 GMT high <p><a href="https://newsroom.aholddelhaize.com/update-on-ahold-delhaizes-cybersecurity-incident/">Source</a></p>
