silentransomgroup

SilentRansomGroup is a ransomware and extortion actor that operates on a data-theft and public-disclosure model, exfiltrating sensitive documents and threatening to publish them on the dark web. ThreatCluster has recorded 138 victims claimed, with sectors most affected including Business Services, Financial Services, Professional Services, Hospitality and Tourism, and Construction, and the countries most affected being US, DE, CA, NZ, and RU. Recent reporting shows a pattern of data exfiltration used to pressure victims, culminating in the publication of stolen material on the dark web, with a concrete illustration in September 2026 when Greenberg Traurig disclosed a data breach in which sensitive documents, including Social Security numbers, were posted on the dark web by SilentRansomGroup.
