Attack summary

Severity: low — No credible attack claim against the actual victim company COMIN S.A.C.; post contains apparent misattribution or confusion with a different entity. No proof files, data exfiltration, or operational disruption documented.

The leak post conflates COMIN S.A.C. (a mining services contractor) with Buenaventura (a major precious metals mining company). No attack details, data exfiltration, or encryption claims are stated against COMIN S.A.C. itself in the post. The post appears to be misdirected or contains a significant naming error.

What the group claims

comin.pe zoominfo.com/c/comin-sac/509891136 Buenaventura Peru's largest publicly-traded precious metals miner — founded in 1953 by Alberto Benavides, now run by the third generation of the family (CEO Leopoldo Benavides), and the first Peruvian company ever listed on the NYSE (BVN, 1996). Its portfolio: underground gold-silver mines (founding Julcani, Yumpag silver star ramping to 10.5M oz/yr, Orcopampa with its new 920m "La Capitana" incline), the ramping open-pit El Agrepión (~200 koz gold-equivalent/yr from 2026), and 71.95% of El Brocal — Peru's largest underground mine, whose Transteki expansion ($250M) doubled its copper output. It also holds 33.75% of Cerro Verde, one of the world's top-10 copper mines (operated by Freeport). Pipeline: option on 40% of Michiquillay (with Anglo American) and Los Chancas JV (Newmont). 2025–26 results are the best in company history: record gold ($3,300/oz) and silver ($36/oz) prices, near-zero debt (0.3x), $1.2B liquidity, dividends restored ~4%

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 838 public disclosures across our corpus. First observed on a leak site on September 9, 2025; most recent post September 9, 2026. The operation is currently active.

If your organisation is affected

A listing by thegentlemen means Comin Sac 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.
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.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
