A ransomware group calling itself ‘the gentlemen’ claims to have carried out an attack against First Coast Heart Vascular Center, with the claim reportedly dated August 14, 2026. This claim originates from an entry on the group’s own dark-web leak site, which was tracked and archived by ransomware.live, a security research platform that monitors ransomware groups’ public leak sites. At this time, First Coast Heart Vascular Center has not issued any public confirmation of an incident, and no regulator or independent investigator has verified the group’s statement. BreachLetter is reporting this solely as a claim made by the threat actor, not as an established fact.
What we know — and don’t
- The group ‘the gentlemen’ listed First Coast Heart Vascular Center on its leak site with a claimed date of August 14, 2026.

- The claim comes from the group’s own listing, as tracked by ransomware.live, and criminal groups have a documented history of exaggerating or fabricating claims to pressure victims.
