T1498.001: DDoS attack,  T1021: Data leaks,  T1036: Exfiltration of sensitive data,  T1204: User data exfiltration, T1001: Data exfiltration over C2 channel,   T1020: Automated exfiltration,   T1037: Data exfiltration via encrypted files,   T1052: Exfiltration over physical medium,  T1108: Reduce security controls,  T1114: Email collection

Recommendations:

·        Work closely with your ISP/Anti-DDoS service provider to evaluate DDoS protection coverage and ensure detection settings are up to date.

·        Evaluate your DDoS attack incident response process with a scheduled mock drill.

·        Leverage CDNs to distribute traffic across multiple data centers, reducing the load on your primary servers.

·        Continuously monitor traffic patterns to identify and respond to unusual spikes that may indicate the onset of a DDoS attack.

·        Use Web Application Firewalls (WAF) and anti-DDoS appliances to filter out malicious traffic and allow legitimate users to access services.

·        Develop a clear communication strategy to inform relevant stakeholders about any potential attacks and mitigation efforts.
