Monti is a financially motivated ransomware operation, also known as Storm-1194. It emerged following the decline of Conti and has been characterized as a Conti doppelganger because its tooling and operational patterns closely resemble those of Conti; analysis has also identified similarities between Monti and Conti code. Monti has conducted extortion through a dedicated leak site and has disproportionately targeted healthcare organizations, including specialty healthcare providers in the United States. The operation has used coercive tactics beyond conventional leak threats, including public allegations concerning victim personnel, publication of sensitive personal information, and humiliating material intended to pressure organizational leadership. Monti-associated activity has included credential theft targeting Veeam backup environments and defense evasion through deployment of an EDR-disabling tool during a 2025 ransomware intrusion.
