The attack has temporarily disrupted operations, including communication, shipping, receiving, and manufacturing. Some systems are back online, but there’s no clear timeline for full recovery yet. Data I/O says it will notify regulators and any affected individuals as required, and the investigation is still ongoing to determine the full scope and impact.
