What the group claims

auren.es zoominfo.com/c/auren/1115886722 AUREN (founded 1998, Madrid) is Spain's leading home-grown multidisciplinary professional-services firm — audit, legal/tax advisory, consulting and corporate finance — with €104 million revenue in Spain and 1,100+ staff in 15 offices (2,500+ people and 62 offices worldwide). Founded and chaired by Mario Alonso Ayala, it sells an integrated "Big Four-style" service portfolio to mid-market companies with a "humanist, close-to-client" culture, plus standout niches in forensic/expert-witness work, public-sector audit and M&A. In March 2025, Dutch private equity fund Waterland took a 49% stake — the first PE investment in a Spanish professional-services firm — giving it firepower for acquisitions. Revenue is split roughly Legal €42M, Consulting €35M, Audit €24M, Corporate Finance €3.4M, and the firm is now on a buy-and-build spree (15–18 deals planned for 2026, its largest being the absorption of Moore España's Madrid and Barcelona offices).

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

If your organisation is affected

A listing by thegentlemen means Auren 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, INCIBE-CERT (Spain), 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.
