Hornetsecurity's annual Cybersecurity Report reveals that in a year of great dynamism, attackers deployed automation, artificial intelligence and social engineering at an unprecedented pace, while defenders rapidly adapted governance, resilience and awareness programs to keep up.
The analysis of over six billion emails processed monthly (72 billion annually) confirms that emails were a constant vector for cyberattacks in 2025. Compared to the previous year, the number of emails containing malware increased by 131%. This increase was accompanied by both email fraud attempts (+34.7%) and phishing (+21%).
