American Vanguard

American Vanguard was compromised in a ransomware attack attributed to osiris in January 2026. The organization, operating in the Manufacturing sector in United States, was added to the group's data leak site as part of an extortion campaign.

osiris 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.
