The next conflict involving the United States may not begin with a missile, a soldier, or a warning siren.

It may begin with code.

In the days following U.S. and Israeli strikes that shook Iran’s leadership, American intelligence officials warned that Iran and its proxies could attempt cyber retaliation. Financial institutions across the United States were quietly placed on heightened alert, increasing monitoring across banking networks and payment systems.

Officials at the U.S. Department of Homeland Security have also said they are monitoring potential cyber threats to critical infrastructure as tensions with Iran escalate.

The warnings received little public attention. Inside the financial sector, however, they were taken seriously.

Those responsible for protecting critical infrastructure understand something the public often does not. Modern conflict rarely begins where people expect it.
