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. Sources say the attack is disrupting the underwriting and claims side of the business, likely due to systems becoming unavailable. The attack has not been confirmed to be a ransomware attack, though it appears likely according to a source familiar with the attack. If it is, the threat actors likely stole business data before encrypting devices.
