For decades, encrypted data was considered secure because cracking it would take classical computers thousands or even millions of years. The quantum threat changed the equation entirely.
Attackers no longer needed to decrypt stolen information immediately. They only needed patience. And foresight is something state actors and well-resourced criminal organisations seem to have in abundance.
They can harvest and store encrypted data today in the expectation that future computing advances will make it possible to crack it. It is a strategy that requires no sophistication at the point of theft, only foresight.
