Operations at $17 billion packaging firm WestRock were disrupted Saturday by a ransomware attack. The attack has already caused delays in some parts of the company’s business, WestRock announced. The company described the incident as likely leading to a loss of revenue and incremental costs that could affect its bottom line. The incident is another reminder of the highly vulnerable nature of OT environments at many organizations, says John Livingston, CEO at Verve Industrial. The US Cybersecurity and Infrastructure Security Agency issued an alert urging organizations in critical infrastructure sectors to beef up security around their OT and control system environment.”]
