A ransomware group calling itself ‘The Gentlemen’ claims to have carried out an attack on Leo Schachter Diamonds, with the claim dated September 2, 2026. This information comes from the group’s own listing on its dark-web leak site, as tracked by ransomware.live, a security research platform that monitors ransomware groups’ public extortion pages. At this time, the claim is unverified — Leo Schachter Diamonds has not issued a public statement confirming or denying an incident, and no regulator has confirmed a breach.
