Herman & Chamow

Herman & Chamow was compromised in a ransomware attack attributed to worldleaks in November 2025. The organization, operating in an undisclosed sector in United States, was added to the group's data leak site as part of an extortion campaign.

worldleaks operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.
