Cybersecurity in 2025: The Most Frequent Cyberattacks in Spain

In 2025, we face a significant increase in cyberattacks, up 66% in the first quarter of the year. Companies suffer an average of 1,925 cyberattacks per week , which represents a 47% increase compared to the same quarter of the previous year.

Phishing cyberattacks

Phishing remains a significant threat in 2025. Cybercriminals use advanced techniques, such as artificial intelligence, to generate fake voices and carry out phone scams, known as "vishing." Phishing attacks targeting university students have also been reported, such as one at the University of the Balearic Islands, where sensitive student and faculty information was exposed.

Ransomware: The Growing Threat

Ransomware has seen a 120% increase in 2025, severely impacting businesses and organizations. This type of attack blocks systems and hijacks critical information in exchange for a ransom. Losses for SMEs can range from €2,500 to €60,000, while for large companies, damages average more than €5.5 million.

Supply chain attacks

Supply chain attacks are affecting businesses and organizations in Spain. Cybercriminals are exploiting vulnerabilities in third-party suppliers to gain access to internal systems. These types of attacks have compromised sensitive data and disrupted critical operations at several Spanish companies.

How to protect your business against cyberattacks

To avoid falling victim to the most common cyberattacks, it is essential to implement key protective measures:

• Continuing education : Train staff in good cybersecurity practices and raise awareness of digital threats.

• Systems Update : Keep all systems and software updated to address vulnerabilities.

• Backups : Make regular backups and store them in secure locations.

• Implementing security solutions : Use antivirus, firewalls, and threat detection and response systems.

• Supplier Assessment : Review and ensure that suppliers meet appropriate security standards.
