Attack summary

Severity: medium — No proof files, screenshots, or data samples are advertised in the post. No specific data categories or operational disruption are detailed. The post reads as an announcement of access/compromise rather than evidence of data exfiltration or encryption. Medium assigned due to the company's scale and sensitive supply-chain/operational data that may be at risk, absent clearer proof.

The group claims to have accessed Leo Schachter Diamonds' systems. The leak post does not specify whether data was exfiltrated, encrypted, or both, nor does it detail what categories of data are at stake beyond the implication of network access.

What the group claims

leoschachter.com Leo Schachter Diamonds (USA/Global) Family diamond house since 1952, four generations; De Beers sightholder for 60+ years. Invented the branded diamond (THE LEO at Kay/Jared, ~2,000 stores) — a diamond sold like a Nike sneaker. Owns one of Botswana's largest cutting factories: 90% women, trained from scratch, plus its own doctor when 60% of staff were HIV-positive. Crisis context: lab-grown diamonds are squeezing the whole natural industry — the moat is now brand + story, not just stones.

Disclosure context

About thegentlemen

thegentlemen is a ransomware group that emerged in September 2025, operating with apparent financial motivations based on their broad targeting of commercial sectors. The group has documented 267 victims across multiple countries, with primary focus on the United States, Thailand, France, Brazil, and India. Their targeting strategy demonstrates a preference for high-value sectors including manufacturing, technology, healthcare, and financial services organizations. Given the group's recent emergence and limited public documentation from established threat intelligence sources such as CISA, FBI, or major security research firms, specific details regarding their country of origin, operational structure, attack methodologies, encryption techniques, and whether they employ ransomware-as-a-service models remain unclear. The relatively high victim count of 267 in a short operational timeframe since September 2025 suggests either an aggressive campaign pace or potential inflation of victim numbers through affiliate operations, though without corroborating intelligence reports, the group's exact operational capabilities and notable campaigns cannot be definitively established. Current intelligence indicates the group remains active as of late 2025, though comprehensive threat profiling requires additional validated reporting from authoritative cybersecurity sources. The group has been linked to 817 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post September 5, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means Leo Schachter Diamonds appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on thegentlemen's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
