CNA Financial, a leading US-based insurance company, has suffered a cyberattack impacting its business operations and shutting down its website.

CNA is considered the sixth-largest commercial insurance company in the USA, according to the Insurance Information Institute, and offers a wide range of insurance products, including cyber insurance policies.

Starting today, CNA's website began displaying a message stating that they are "currently experiencing a network disruption that is impacting some of our systems. We are working to address these issues to minimize the disruption to you."
In an updated statement on their website, CNA has confirmed that a cyberattack is causing network disruption, including corporate email. To be safe, CNA also confirmed that they disconnected their systems from the network.

The full statement from CNA can be read below.
"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.

Upon learning of the incident, we immediately engaged a team of third-party forensic experts to investigate and determine the full scope of this incident, which is ongoing. We have alerted law enforcement and will be cooperating with them as they conduct their own investigation.

Out of an abundance of caution, we have disconnected our systems from our network, which continue to function. 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 security of our data and that of our insureds’ and other stakeholders is of the utmost importance to us and we are committed to continuing to serve them as we work to resolve this issue. Should we determine that this incident impacted our insureds’ or policyholders’ data, we’ll notify those parties directly." - CNA.

The new Phoenix Locker ransomware used in the CNA attack is believed to be another Evil Corp spinoff.
When BleepingComputer asked CNA about a connection between the sanctioned Evil Corp and the Phoenix group, they replied that there was no confirmed nexus.
"The threat actor group, Phoenix, responsible for this attack, is not a sanctioned entity and no U.S. government agency has confirmed a relationship between the group that attacked CNA and any sanctioned entity. We have notified the FBI of this incident and are actively cooperating with them as they conduct their investigation of the incident."
