Fidanque Hermanos e Hijos, S.A Listed by NightSpire Ransomware Group

On February 26, 2026, Spanish company Fidanque Hermanos e Hijos, S.A. appeared on the leak site of the nightspire ransomware group. Public reporting indicates the attackers exfiltrated internal files including financial documents, internal documents, and MSSQL database contents before encrypting systems. While the exact number of individuals whose personal information may have been exposed remains unknown, anyone whose data was stored in the company’s financial or customer records could be affected.

What Public Reporting Shows

Available reporting describes a classic ransomware double-extortion incident. The nightspire group claims to have stolen sensitive company files and is threatening to publish them if demands are not met. The data categories listed on the leak portal include financial records that often contain names, addresses, tax identifiers, bank details, and supplier or customer information. No precise volume of records or list of specific victims has been publicly detailed beyond the broad categories of financial documents, internal documents, and MSSQL database.

The incident follows the group’s standard pattern of breaching a target, exfiltrating data, deploying ransomware, and then using the public leak site as leverage. As of the publication date on the leak site, the company had not issued a public statement confirming the breach or detailing what safeguards, if any, were in place.

Why This Matters for You and Your Family

When a company that handles financial or personal records is breached, the information can be used to target you directly. Fraudsters may combine leaked names, addresses, and account numbers to attempt identity theft, file fraudulent tax returns, or open accounts in your name. If your employer, bank, supplier, or service provider used Fidanque Hermanos e Hijos, your data could be among the records now in attackers’ hands.
