A breach at logistics giant Ceva hit banks, retailers and gamers: the domino effect in data chains

A data breach at logistics giant Ceva Logistics, as TechCrunch reported, is spreading in circles across wildly different industries: banks, retailers and even Steam gamers felt the consequences. The logistics operator turned out to be a node through which many companies' data flowed — and one incident became dozens of other people's problems.

Tellingly, some of those hit had no direct relationship with Ceva at all: their data reached the operator through second-tier partners and contractors. This is the rarely considered second level of supply-chain risk: you can vet your own vendors carefully and still suffer from the breach of a company you never knew existed.

Full control over such a chain is impossible, but the damage can be reduced. First: hand partners the minimum data sufficient for the job instead of exporting everything. Second: ask key contractors who they pass your data on to. Third: keep a plan for someone else's incident ready — who in your company learns of it first and what gets said to customers. In an era when data for AI tools and analytics shuttles between dozens of systems, such a flow map has stopped being a luxury.
