CNA confirms ‘sophisticated’ cyber attack on systems


CNA Financial has been the victim of a cyber attack causing network disruption.

In a statement on its website, the firm said it sustained a “sophisticated” cyber-security attack on 21 March, which affected certain CNA systems, including corporate email.

CNA added that it disconnected its systems from the network and provided employee workarounds where possible to ensure it could continue serving insureds and policyholders.

A team of third-party forensic experts has been engaged to investigate and determine the full scope of the incident, which is ongoing, CNA explained.

“We have alerted law enforcement and will be cooperating with them as they conduct their own investigation,” it said.

“The security of our data and that of our insureds and other stakeholders is of the utmost importance to us. Should we determine that this incident impacted our insureds or policyholders’ data, we’ll notify those parties directly.”

Other insurers have previously been victims of cyber attacks. Chubb confirmed in March last year that it was investigating a potential computer-security incident, following reports it had been attacked by a cyber ransomware group known as Maze.

The cyber insurance industry has also been tackling the rise of ransomware attacks on the underwriting side of the business, which has caused rates to spike and a market-wide reunderwriting of the risk.
