TheGentlemen ransomware added 14 new victims to its leak site in a 46-minute window on June 1, with the most consequential target being Suburban Water — a US water utility that falls under CISA’s National Critical Infrastructure Sectors designation. The posting marks one of the more operationally significant ransomware disclosures of the month, given the essential public services water utilities provide.
Suburban Water and the Critical Infrastructure Risk
The inclusion of a water utility in TheGentlemen’s victim list elevates the disclosure beyond a typical multi-sector ransomware batch. Water utilities occupy a distinct threat category because ransomware intrusions can affect systems that extend well beyond the data environment: billing platforms, service management software, and emergency response coordination systems may all operate on infrastructure shared with or adjacent to compromised networks.
For residential and municipal customers, disruption to those systems can translate to service delivery failures that are difficult to address quickly, particularly in communities dependent on a single water provider.
Suburban Water as CISA-Designated Critical Infrastructure
Suburban Water’s classification under CISA’s critical infrastructure framework means an attack on its systems carries national security implications beyond the immediate operational disruption. CISA tracks water and wastewater systems as a protected sector specifically because of the population-level consequences of service failure. TheGentlemen’s posting does not detail what data or systems were accessed, but the group’s history suggests exfiltration of operational and administrative records precedes or accompanies encryption activity.
Fourteen Victims Across Five Sectors and Three Countries
The June 1 batch extended across a broad range of sectors. In the US, victims included Soniva Dental in healthcare, Brian Jessel BMW in automotive, National Industries and Weckworth Manufacturing in manufacturing, and Harrell Martin Peace in the legal sector. The technology sector was represented by Computime Group. International victims included Fibrenoire and Arabian Procession Holding, M Rocha J Serra Lda in Portugal, Smile Siam Printing Service in Thailand, and Anandji Haridas and Grupo LTZ rounding out the batch.
The geographic spread — across the United States, Portugal, Thailand, and Canada — reflects TheGentlemen’s operational model, which relies on a large and internationally distributed affiliate network rather than centralized attack operations.
TheGentlemen’s RaaS Model and 2026 Volume
TheGentlemen has accumulated more than 332 published victims in the first five months of 2026, establishing it as the second-most active ransomware group by victim count during that period. The group operates a ransomware-as-a-service model and offers affiliates a 90% revenue share on ransom payments — the highest split documented in the current RaaS ecosystem. That structure has driven rapid affiliate recruitment, which directly correlates with the attack volume the group has sustained since the start of the year.
TheGentlemen’s June 1 Activity After May 2026 Infrastructure Exposure
The June 1 victim batch is notable for a second reason beyond the critical infrastructure target: it follows a significant operational setback the group experienced in May 2026, when 16.22 gigabytes of TheGentlemen’s internal group data were exposed in a breach of the group’s own infrastructure. The disclosure of that data — which would typically include affiliate communications, victim negotiations, and operational tooling — did not interrupt operations. The 14-victim batch posted the following month demonstrates that the group absorbed the exposure without meaningful disruption to its affiliate recruitment or attack pipeline.
Ransomware groups that survive infrastructure compromise typically do so because their affiliate model decentralizes operational risk: individual affiliates conduct attacks independently, meaning a breach of the core group’s administrative infrastructure does not disable the distributed network of actors carrying out intrusions. TheGentlemen’s June 1 activity is consistent with that pattern.
The combination of a 90% affiliate revenue share, 332 victims in five months, and demonstrated resilience following its own infrastructure breach positions TheGentlemen as one of the more durable ransomware operations active in 2026. The targeting of Suburban Water adds critical infrastructure to a victim portfolio that already spans healthcare, manufacturing, legal services, and technology.
