Our take

The combined CIO and CSO at Ledger, whose appointment was announced in September 2026, came over from the same dual role at Fireblocks. The opening of the post frames AI as a shift in the cost of mounting an attack, where the old constraint was how many skilled operators an adversary could afford to hire. We think the cost framing is the useful one, because it moves the question from whether a technique exists to how cheaply it can be repeated. A defence that was acceptable because it priced out all but well-funded crews deserves a fresh look once volume and speed stop being scarce. We would revisit assumptions about low-value targets, since cheap attacks make them worth the effort. We would also stress-test detection and response at higher volume rather than only at higher sophistication, and measure how much each control costs an attacker to bypass, not whether it can be bypassed.
