grupopuma Listed by nova Ransomware Group

If you are a customer of grupopuma, here’s what is being claimed, and what it would mean for you.

grupopuma was listed on Nova's leak site. Nova claims to have stolen internal data. This is the group's claim, not a confirmed finding.

grupopuma Listed by nova Ransomware Group

On December 9, 2025, the nova Ransomware Group listed Grupo Puma on its leak site, claiming that internal files had been exfiltrated from the construction company. The data includes local folders, program credentials, databases and additional material. While the exact number of people whose personal information appears in the files remains unknown, anyone whose records were stored in Grupo Puma’s systems could be affected.

You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Reported Details from Reporting

Public reporting indicates that nova Ransomware gained access to Grupo Puma’s network, copied sensitive internal documents, and later published a sample on its dark-web leak page. The exposed material contains program credentials and databases alongside ordinary business folders. The listing appeared on the nova leak site hosted at a Tor address tracked by ransomware.live. No ransom payment deadline has been publicly confirmed in available reporting, but the group’s standard practice is to pressure victims by gradually releasing more data if demands are not met.

Why This Matters for You and Your Family

When a construction company like Grupo Puma suffers a breach, the credentials and databases it loses often contain information supplied by customers, suppliers, and employees. That can include names, addresses, contact details, and payment records. Once those details surface on a ransomware leak site, they become easy targets for identity thieves, phishing campaigns, and doxxing attempts. For ordinary families, this means the risk is not abstract: your personal data could be packaged and sold alongside thousands of others, leading to unexpected charges, loan applications in your name, or harassment tied to leaked contact information.

Credential leaks are especially dangerous because the same password used for a supplier portal may also protect your email, banking, or social-media accounts. Children’s information sometimes appears in family-linked records, exposing them to long-term identity risks before they even have credit files of their own.

The Doxxing and Identity-Chain Risks

Ransomware groups rarely stop at one leak. Once initial data appears, opportunistic attackers scan it for email addresses, usernames, and phone numbers, then cross-reference those details across social media, gaming platforms, and data-broker sites. This creates an identity chain that can reveal your home address, family relationships, and even children’s gaming handles. A single exposed database record can therefore cascade into account takeovers on services you use every day. Public reporting shows these chains frequently lead to doxxing, where personal details are published to embarrass victims or demand further payment.

Nova Ransomware Group’s Known Activity

Public reporting attributes the nova Ransomware Group with operations that emerged in recent years. The group typically gains initial access through common vectors such as phishing or unpatched remote desktop services, exfiltrates data before encrypting systems, and then posts samples on its leak site to pressure victims. Notable prior targets have included companies in manufacturing and services sectors, though exact victim lists fluctuate as new incidents are confirmed. The group’s playbook centers on data theft followed by extortion rather than solely encryption, a pattern consistent with the Grupo Puma listing.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this claimed breach has exposed.
  • Rotate any password you used at Grupo Puma or related supplier portals, then enable two-factor authentication through an authenticator app on every account where that password was reused.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next credential leak is caught and addressed within hours rather than months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often become entry points for doxxing chains when parent credentials are exposed.
  • Let remediation specialists handle takedown requests across data brokers and leak sites so you do not have to negotiate or chase down each instance yourself.

The Grupo Puma incident illustrates how quickly business data breaches become personal threats. Taking concrete steps now can limit the damage from this leak and reduce exposure to future ones. Start your DoxxScan trial and let its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage—including children’s gaming accounts—work on your behalf. Anyone whose information was stored with Grupo Puma should treat this listing as a prompt to act.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
