Security News > 2022 > June > Walmart denies being hit by Yanluowang ransomware attack
American retailer Walmart has denied being hit with a ransomware attack by the Yanluowang gang after the hackers claimed to encrypt thousands of computers.
"We believe this claim is inaccurate and are not aware of a successful attack in this regard on our devices," a Walmart spokesperson told BleepingComputer.
The ransomware gang further told BleepingComputer that they claimed to have conducted the attack over a month ago and were able to encrypt devices but not steal any data.
As part of this attack they say they demanded a $55 million ransom but never received a response from Walmart.
The entry on the data leak site includes various files that allege to contain information extracted during the attack from Walmart's Windows domain.
While Walmart denies an attack was successful, these files contain information that claims to be from Walmart's internal network, including a security certificate, a list of domain users, and the output of a kerberoasting attack.
