CNA Insurance hit by sophisticated Cyber Attack.

By Robert Channick, Chicago Tribune


CNA’s website remained down Wednesday morning, three days after the Chicago-based insurance giant was hit with what it called a “sophisticated cybersecurity attack” Sunday.

In a statement issued Tuesday evening, CNA said the attack “caused a network disruption” that affected certain systems, including corporate email. It also shut down the functionality of its website.



“Out of an abundance of caution, we have disconnected our systems from our network, which continue to function,” the company said. “We’ve notified employees and provided workarounds where possible to ensure they can continue operating and serving the needs of our insureds and policyholders to the best of their ability.”

The company’s website, www.cna.com, has been reduced to a static display that includes its statement about the cybersecurity attack and dedicated email inboxes to handle claims during the outage.

“Should we determine that this incident impacted our insureds’ or policyholders’ data, we’ll notify those parties directly,” CNA said.


CNA, a subsidiary


of Loews Corp., was founded in 1967, with its predecessor insurance companies dating back to 1897.


For more than four decades, CNA was perhaps best known in Chicago for its iconic red corporate headquarters on South Wabash Avenue. It relocated to a new high rise at 151 N. Franklin St. in 2018.
