What the group claims

Today, we’re opening the auction.Over the past several weeks, we’ve completed a full exfiltration from the infrastructure of Quality Data Service, Inc., Connecticut’s most “trusted” municipal software provider. The haul: approximately 300 GB of internal company data, including:SQL databases of client municipalities, tax departments, GIS records, and user credentialsGigabytes of PDFs, XLS files, DOC reports — many containing deeply sensitive financial, geographic, and personal data with contatsInternal emails, technical logs, software source code archives, vulnerability reports, and support ticketsMost importantly: comprehensive information on over 200 Connecticut municipalities, their operational structures, internal correspondences, and revaluation recordsThese aren’t just files. These are lives, towns, histories, and vulnerabilities — trusted to a company that no longer respects the responsibility it bears.Why Are We Doing This?We approached Quality Data Service, Inc. privately before publishing anything. Our intent was not destruction. But from the Founder & President, to the CFO, Director of Assessor Support,ITs and others — we received silence, evasion, or worse: denial.They knew.They were warned.They did nothing.Their refusal to act wasn’t just negligence — it was an act of contempt for every municipality they serve.It’s not just about stolen data. It’s about a culture that prioritizes profit over protection, and PR over real recovery. And when cybersecurity “experts” are called in only to recommend burning what’s left — that’s not incident response. That’s malpractice.The AuctionWe are now offering:Full dataset: All stolen data, intact and complete (buyout option)Per-municipality packages: Tailored datasets for each town or districteQuality source code: Core application and modules available separatelyBuyers of individual municipality data will receive exclusive access — upon purchase, that data will be removed from general availability. (We believe in boundaries, even if others do not.)If You're a VictimIf your municipality is among the affected, you can contact us.We offer:Permanent removal of your data from our archives and auctionTechnical documentation proving the breachInternal evidence of the company’s failure to act, including logs and communications with their leadershipAssistance in legal proceedings to seek compensation from Quality Data Service, Inc.Names of involved individuals include:Vinny Crudele, Founder & President [email protected] 203-758-9446Leo Dinicola, Chief Financial Officer [email protected] 860-417-3538 203-910-2316 [email protected] Gordon, Director of Tax Support [email protected] Crudele, Director of Assessor Support [email protected] 860-417-3617 203-518-1655David Crudele, Chief Operations Officer [email protected] 203-758-9446 203-598-2692Bryan Reilly (IT) [email protected] 860-202-9557Tom Tanganelli (IT) 860-456-2814 860-384-2449 [email protected] Johnson (Sales) 860-643-8100 860-729-4551 [email protected] Lavoie (Programming) 860-620-0785 860-919-1343 [email protected] Powell (eQuality) 203-509-4255 [email protected] take no joy in exposing them. But in the end, they chose convenience over courage.A Better WayYou may dislike what we’ve done — but it was never random.IT security is not a checkbox. It’s a culture. And we’ve seen firsthand how a failure to treat it seriously leads to the slow death of public trust. The worst thing about this breach is not the breach itself, but that it could have been prevented.We call on municipalities, CTOs, assessors, and public servants to work with real specialists who care more about solutions than headlines. The future belongs to those who build with integrity.listing https://gofile.io/d/5641ll

Disclosure context

About blacknevas

Blacknevas is an emerging ransomware group that was first observed in August 2025, appearing to be primarily financially motivated based on their targeting patterns and operational characteristics. The group's origin and potential affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their diverse geographic targeting suggests either a distributed operation or broad opportunistic approach. Based on available victim data, Blacknevas has compromised at least 23 organizations across multiple countries, with the United States, Spain, India, Japan, and Thailand being the most frequently targeted nations, while their sector focus spans technology, manufacturing, energy, and consumer services industries, suggesting they employ opportunistic rather than sector-specific targeting methodologies. The group's attack vectors, specific tools, and whether they operate as a Ransomware-as-a-Service model or maintain independent operations have not been publicly documented by major cybersecurity firms or government agencies. Due to the group's recent emergence in August 2025, there is insufficient public reporting from established sources like CISA, FBI, or major threat intelligence providers to detail notable campaigns or significant attacks beyond the confirmed victim count. Given the recency of their first observed activity, Blacknevas appears to remain active as of late 2025, though comprehensive threat intelligence profiles from authoritative sources have yet to be published. The group has been linked to 36 public disclosures across our corpus. First observed on a leak site on August 6, 2025; most recent post July 14, 2026. The operation is currently active.

Also tracked as: black nevas.

If your organisation is affected

A listing by blacknevas means Quality Data Service, Inc. 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 blacknevas'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.
