Castilla Listed by Nova Ransomware Group

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

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

Castilla Listed by Nova Ransomware Group

On November 2, 2025, Spanish company Castilla appeared on the leak site of the nova Ransomware Group. The listing states that internal files were exfiltrated during a ransomware attack on the small consumer-services business, which employs between five and nine people and generates between one and five million dollars in annual revenue from its headquarters in Soria, Castille and Leon.

Already exposed?

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 580 companies.

Reported Details of the Breach

Public reporting indicates that Castilla’s internal files were stolen and are now hosted on the nova leak site. The exact number of people whose data appears in the files remains unknown. No specific deadline for payment has been publicly detailed in the listing, though ransomware groups routinely set short windows before full publication. The compromised material consists of documents that would normally remain inside the company’s private network.

Why This Matters for You and Your Family

Even a small business breach can expose the personal information of customers, suppliers, and employees. If you or anyone in your family has interacted with Castilla as a client or vendor, your contact details, addresses, or payment records could be among the stolen files. Once that information reaches dark-web marketplaces, it rarely disappears. Criminals combine it with data from other breaches to build complete profiles that make identity theft, phishing, and harassment far easier. For ordinary families this means months or years of extra vigilance against unexpected charges, loan applications in your name, or unwanted contact.

The Doxxing and Identity-Chain Risk

Stolen internal files often contain email addresses, phone numbers, employee names, and customer spreadsheets. These pieces act as anchors that link your online handles to your real-world identity. A single leaked work email can reveal your personal accounts through password reuse or password-reset flows. The chain grows quickly: one exposed credential leads to a gaming account, a family photo folder, or a child’s username. Available reporting describes how such cascades frequently end in full doxxing, with home addresses, family member names, and live locations posted publicly. Credential leaks like this one therefore threaten not only corporate data but also the personal safety of anyone whose information touched the affected systems.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
