Kaspersky’s detection systems discovered an average of 500,000 malicious files per day in 2025, marking a 7% increase compared to the previous year. Certain types of threats saw growth globally – there was a 59% surge in password stealer detections, a 51% growth in spyware detections and a 6% growth in backdoor detections compared to 2024.
Findings from the Kaspersky Security Bulletin
These findings are part of the Kaspersky Security Bulletin series where key cybersecurity trends of the past year are reviewed.
Windows and Mac Users Targeted by Cyberattacks
Windows remains the primary target for cyberattacks. 48% of users on Windows were targeted by different types of threats throughout 2025. For Mac users, this figure stands at 29%.
Global Spread of Web Threats
Globally, 27% of users were attacked with web threats – malware that targets users when they are online. In Latin America, 26% of users were attacked by web threats in 2025, while this share reached 25% in Africa, 21% in Europe and 19% in the Middle East.
On-Device Threats Across Regions
33% of users were attacked with on-device threats, including malware spread via removable USB drives, CDs and DVDs, or hidden in complex installers. Africa recorded the highest share at 41%, followed by APAC at 33%, Middle East at 32%, Latin America at 30%, and Europe at 20%.
Sophisticated Multi-Platform Attacks Emerging
“The current cyberthreat landscape is defined by increasingly sophisticated multi-platform attacks,” said Vladimir Kuskov, Head of Anti-Malware Research at Kaspersky. He highlighted the resurgence of the Hacking Team and the use of commercial spyware Dante in the ForumTroll APT campaign, which exploited zero-day vulnerabilities in Chrome and Firefox.
Importance of Protective Solutions and Training
Kaspersky emphasized the need for detection and response tools, patch management, infrastructure monitoring, and vulnerability analysis. Equally important are user and employee training programs to strengthen awareness against phishing and social engineering.
Recommendations for Users and Organizations
Individual users are advised not to download applications from untrusted sources, avoid suspicious links, enable two-factor authentication, and install updates promptly. Organizations are urged to keep software updated, avoid exposing remote desktop services, use strong passwords, and adopt advanced security products for comprehensive visibility and threat intelligence.
