Malaysia Airlines confirmed this week that a cybersecurity incident at its third-party reservation provider, Amadeus, may have exposed customer booking data spanning nearly three years. Cathay Pacific (~53,000 bookings) and Japan Airlines (~92,000 customers) have also been affected.
Here's what stands out: Malaysia Airlines says its own IT systems were never compromised. The weak link wasn't the airline — it was the vendor.
This is the supply chain risk every business faces. You can have strong internal security, patched endpoints, and solid policies, but if a vendor handling your customer data gets hit, you're exposed anyway.
The difference between a headline and a manageable incident often comes down to how quickly you learn about it and how prepared you are to respond. That's where proactive IT management matters.
For MyIT clients, vendor security awareness and rapid incident response aren't extras — they're part of the service. If you're still handling IT reactively, this is the kind of story that should prompt a conversation.
