# Incident Report: Ahold Delhaize Data Exfiltration and Confirmed Breach
## Executive Summary
Multinational retailer Ahold Delhaize confirmed a data breach following claims by the INC Ransom group that they executed a ransomware attack and stole sensitive information. The incident, which led to the temporary shutdown of some IT systems for remediation (primarily affecting Ahold Delhaize USA brands, pharmacies, and e-commerce), resulted in the public confirmation of data theft. The attackers utilized extortion tactics by posting stolen data samples on their dark web site.
## Incident Details
- **Discovery Date:** A public statement was issued on November 8, 2024, disclosing a cybersecurity issue that forced system shutdowns.

## Timeline of Events
### Initial Access
- **Date/Time:** Undisclosed, occurred prior to November 8, 2024.
- **Vector:** Not explicitly detailed in the provided text, but implied to be an intrusion enabling ransomware deployment and data theft.
- **Details:** N/A
### Lateral Movement
- Details regarding internal movement are not specified, but were likely necessary to facilitate data collection prior to exfiltration.
### Data Exfiltration/Impact
- **What was stolen or damaged:** Sensitive information was stolen, confirmed by Ahold Delhaize following the publication of data samples by INC Ransom. The scope potentially includes customer data, which would trigger notification requirements if confirmed.
- **Impact of Ransomware:** Certain Ahold Delhaize USA brands and services, including a number of pharmacies and some e-commerce operations, were taken offline as a mitigating action.
### Detection & Response
- **How it was discovered:** The company issued a public statement on November 8, 2024, confirming an ongoing cybersecurity issue. Detection was potentially triggered by internal systems monitoring or the subsequent public extortion attempt by INC Ransom.
- **Response actions taken:** The company forced certain IT systems offline as a mitigating action. They have notified and updated law enforcement and stated they will notify affected individuals if personal data is confirmed to have been impacted.
## Attack Methodology
- **Initial Access:** Undisclosed.
- **Persistence:** Maintenance of access was achieved long enough for data collection, likely leveraging methods associated with ransomware operations.
- **Privilege Escalation:** Not detailed.
- **Defense Evasion:** Not detailed, but evidenced by successful data collection and exfiltration.
- **Credential Access:** Not detailed.
- **Discovery:** Not detailed (assumed internal network reconnaissance occurred).
- **Lateral Movement:** Implied, given the scope affecting multiple brands and services in the USA.
- **Collection:** Data was collected for extortion purposes.
- **Exfiltration:** Data was successfully exfiltrated and posted on the INC Ransom dark web extortion site.
- **Impact:** Data theft (extortion) and operational disruption (IT system shutdowns).
## Impact Assessment
- **Financial:** Undisclosed, but significant due to operational impact on US brands and potential regulatory costs.
- **Data Breach:** Sensitive information was stolen. Ahold Delhaize stated they will notify affected individuals if *personal data* is confirmed impacted.
- **Operational:** Affected certain Ahold Delhaize USA brands, several pharmacies, and e-commerce operations were taken offline temporarily. Store operations remained open and operational.

## Indicators of Compromise
*No specific network, file, or behavioral IOCs were available in the source text.*
## Response Actions
- **Containment measures:** Forced certain IT systems associated with Ahold Delhaize USA offline.
- **Eradication steps:** Investigation remains ongoing.
- **Recovery actions:** Store and e-commerce operations were confirmed to remain open and operational.
## Lessons Learned
- **Key takeaways:** The attack demonstrates that major multinational retailers remain prime targets for sophisticated ransomware groups like INC Ransom (which has targeted other entities like the State Bar of Texas).
- **What could have been done better:** The initial means of exploitation and the extent of data compromise during the dwell time were not sufficiently protected against.
## Recommendations
- Review and enhance network segmentation, particularly isolating critical US-based operational networks from potential points of initial compromise.
- Increase scrutiny of threat intelligence related to the INC Ransom group's tactics, techniques, and procedures (TTPs), especially considering their recent focus on US organizations.
- Harden controls related to ransomware deployment, including endpoint detection and response capabilities, and robust offline/immutable backups to minimize downtime and extortion pressure.
