What should you do?
Customers should monitor official brand channels for updates on service restoration timelines. Managers should review internal communication plans to ensure clear updates are available for employees and partners during such outages.
The background in plain language
When organizations detect unauthorized access, they often take systems offline to prevent further data loss or system damage. This precautionary step prioritizes security over immediate availability. Teams usually verify the extent of the breach before restoring services. Check whether your organization has a clear incident response plan that outlines communication protocols during such events to minimize confusion among stakeholders.
What to do and how to stay safe: Ahold Delhaize
- Monitor official company announcements for updates on service restoration and potential changes to delivery schedules.
- Avoid clicking on suspicious links or emails that may exploit the ongoing incident for phishing attempts.
- Ensure your own devices and accounts have strong, unique passwords enabled to reduce personal exposure to secondary threats.
- Review your organization’s incident response procedures to ensure they address communication and system isolation effectively.
