Sam’s Club, a division of Walmart Inc., is investigating a possible cyberattack referenced by the Clop ransomware gang on a leak site. Despite Clop’s mention, there is no specific information made public suggesting exfiltration of company or customer data. With over $86 billion in net sales and about 600 warehouse clubs, Sam’s Club has not confirmed any cyber intrusion or security incidents. The threat is linked to zero-day vulnerabilities in MOVEit and Cleo file transfer software, exploited by Clop for data extortion, highlighting a shift from file encryption to data theft for monetization.
