Exfiltration of sensitive PII including SSNs and passport numbers. Potential for large-scale identity theft and significant legal liabilities for the airline. The attack occurred in two waves during May and June, targeting internal systems to exfiltrate high-value identity documents. The theft of Social Security and passport numbers significantly increases the risk of long-term identity theft for the affected individuals. The reported delay in notification suggests critical failures in the company’s incident response and transparency protocols.
