Commercial insurer CNA on Tuesday announced that it was recently targeted in what it described as a sophisticated cyberattack.
In a March 23 announcement, the company revealed that, over the weekend, it fell victim to a cyberattack that impacted certain systems, and which resulted in network disruptions.
"On March 21, 2021, CNA determined that it sustained a sophisticated cybersecurity attack. The attack caused a network disruption and impacted certain CNA systems, including corporate email," the company says in an incident notification on its website.
"Out of an abundance of caution, we have disconnected our systems from our network, which continue to function," CNA also says.
CNA has yet to determine whether any information related to its clients or other type of data has been impacted in the incident.
While CNA hasn't revealed the nature of the cyber-attack, there is a possibility that the company fell victim to ransomware operators, which would explain why systems were disconnected from the network.
