Magento Store Hacked? Emergency Recovery Guide for First 24 Hours

If your Magento store is hacked, the first 24 hours determine business impact. Speed matters, but unstructured panic causes more damage. Use this incident response sequence to contain risk and recover with evidence intact.

Hour 0 to 2: Contain the incident

Immediately do the following:

• Put storefront in maintenance mode
• Rotate admin credentials and revoke unknown users
• Block suspicious IP addresses at WAF or firewall
• Pause risky integrations until review is complete

Containment prevents lateral movement and additional data exposure.

Hour 2 to 6: Preserve evidence before cleanup

Before removing files or extensions:

• Take full file system snapshot
• Export database backup with timestamp
• Copy web server and application logs
• Record IOC details such as malicious filenames and IPs

Without evidence, root-cause analysis becomes unreliable.

Hour 6 to 12: Identify likely attack path

Review the common Magento compromise vectors:

• Outdated core or vulnerable extension
• Exposed admin path without hardening
• Weak credentials or reused passwords
• Compromised CI deployment key

Create a timeline from earliest suspicious event to discovery.

Hour 12 to 18: Restore from clean baseline

Recovery should be controlled:

• Rebuild from known-clean code release
• Reinstall only vetted extensions
• Apply all security patches and dependency updates
• Verify cron jobs and payment callbacks

Do not restore unknown custom code without review.

Hour 18 to 24: Validate and reopen carefully

Before going live:

• Run checkout and payment sanity tests
• Verify no injected scripts on product, cart, and checkout pages
• Enable extra monitoring and alert thresholds
• Document incident summary for legal and compliance review

Reopen in stages and watch error and fraud signals closely.

Post-incident hardening checklist

After service is stable:

• Enforce MFA for all admin accounts
• Restrict admin access by IP and VPN
• Add file integrity monitoring
• Establish patch cadence and extension audit schedule

Final takeaway

Good recovery is not just bringing the site back online. It is restoring trust, preserving evidence, and reducing probability of recurrence.
