Spain’s Ministry of Finance has denied that an unprecedented cyberattack took place on its databases.
It comes after claims circulated online suggesting that the personal, banking and tax data of around 47.3 million citizens and residents had been compromised.
The Spanish Tax Agency carried out an internal investigation and ruled out any security breach, according to sources from the ministry headed by Maria Jesus Montero.
Finance officials said there was no evidence that a hack had occurred, although the ministry’s security teams examined the claims as a precautionary measure.
The alert originated from cybersecurity firm Hackmanac, which posted on social media platform X about a possible cyberattack allegedly affecting the Ministry of Finance.
The firm cited claims by a group calling itself ‘HaciendaSec’, which said it had carried out the attack.
According to those claims, the attackers were allegedly offering for sale a database containing DNI/NIF numbers, full names, home addresses, phone numbers, email addresses, banking details and tax-related financial information.
However, Spanish tax authorities insist that their checks have found no indication that any such data breach took place, and that citizens’ personal and fiscal information has not been compromised.
