Basque Police Report Surge in Crypto Crime with 541 New Investigations

The Ertzaintza, the primary police force of Spain’s Basque Autonomous Community, has reported a significant increase in digital asset-related criminal activity. According to recent data disclosed on March 17, 2026, law enforcement officials are currently investigating 541 individual cases involving various forms of cryptocurrency-based offenses. This surge has prompted regional authorities to bolster their technological infrastructure and human resources to counter the evolving landscape of decentralized financial crime.

Enhanced Surveillance and Specialized Cybercrime Units

To address the growing complexity of these investigations, the Basque police have established a dedicated cybercrime unit comprising 26 specialized detectives. This team is tasked with monitoring suspicious activities across multiple blockchain networks, utilizing advanced forensic tools to track transaction flows and identify illicit actors. The scope of the ongoing inquiries is broad, reflecting the diverse ways in which bad actors exploit virtual assets.

• 13 cases involving sophisticated cryptocurrency fraud schemes.
• 2 investigations into large-scale crypto-assisted money laundering.
• Multiple instances of tax evasion related to digital asset holdings.
• Illegal acquisition of goods and services via unregulated crypto channels.

Common Tactics and Social Engineering Methods

Police reports highlight a shift toward social engineering on platforms such as Instagram. Fraudsters often impersonate family members or close acquaintances to provide unsolicited investment advice. These interactions typically lead to the victim installing malicious software designed for remote device control, which allows the attacker to bypass security measures and drain both crypto wallets and traditional bank accounts. The use of remote access trojans (RATs) has become a prevalent method for bypassing two-factor authentication in the region.

The perpetrators utilize the anonymity of the blockchain to facilitate tax evasion and the illegal purchase of services, necessitating more robust monitoring tools for our detectives.

The rise in criminal cases within the Basque Autonomous Community mirrors a broader global trend where law enforcement agencies are increasingly forced to modernize their tactics. By integrating specialized tracking software and expanding its detective force, the Ertzaintza aims to reduce the success rate of hacking and phishing operations targeting Spanish residents. As investigations into the 541 reported cases continue, authorities urge the public to remain vigilant against fraudulent investment schemes and unauthorized third-party applications.
