Cyberattacks Join Missiles as Combat Weapons—at Great Risk to U.S. Business

By Kim S. Nash

 

Welcome back. "Expect disruptions." That's how Jen Easterly, former director of the Cybersecurity and Infrastructure Security, put it at WSJ's cybersecurity conference last week. 

Easterly referred to Iran using its cyber capabilities against U.S. businesses as the U.S.-Israeli bombing there goes on. 

Retaliatory cyber strikes can inflict lasting damage: costly outages of internal office systems, manufacturing delays, lengthy recovery periods and reputational harm—all of which take a financial toll that might not be covered by standard business or cyber insurance. Read our full story.

These scenes are playing out at medtech company Stryker, which is still dealing with the effects of cyberattack linked to pro-Iran hackers. An update on Stryker, and more news, below.

As Stryker works to restore order systems and other critical operations tied to its Microsoft environment that were downed after last week's cyberattack, shares in the company continue to fall. "Orders placed prior to the disruption will be reconciled as systems are restored, and electronic orders placed during the disruption will process once systems are back online, and supply is flowing normally," Stryker said Sunday, giving no timeline for restoration.
