Post-Hack Recovery & Operations

The Challenge

After a hacker attack, a web application with tens of thousands of active users was taken offline as a preventive measure. The code itself was not compromised – the priority was the safe restoration of normal operations. Critical questions: How to ensure no unauthorized payments are triggered during restart? How to compensate users for the downtime?

The Solution

Methodical preparation and controlled relaunch of the application with special focus on financial integrity and user satisfaction.

Analysis & Preparation

• Payment Audit: Detailed review of all pending and scheduled transactions for anomalies or manipulated orders.
• Queue Inspection: Review of all job queues and scheduled tasks that had accumulated during the downtime.
• Database Consistency: Ensuring data integrity and identifying records that may have been manipulated during the attack.

Recovery Measures

• Payment Security: Temporary blocking of all automatic payouts until manual approval of suspicious transactions.
• Account Extension: Automatic extension of all user accounts by the duration of the downtime – fair compensation for affected customers.
• Staged Rollout: Gradual reactivation of system functions with close monitoring.
• Communication: Proactive information to all users about the status and measures taken.

Quality Assurance

• Transaction Monitoring: Real-time monitoring of all outgoing payments in the first days after relaunch.
• Anomaly Detection: Automatic alerts for unusual transaction patterns or volumes.
• Support Readiness: Enhanced customer support for inquiries and problem reports.

The Result

The application went back online in a controlled manner – without any unauthorized payments being triggered. The automatic account extension strengthened customer trust and minimized complaints. The entire process demonstrated professional crisis management under high time pressure.
