Over 1 in 20 emails are malicious, warns internet giant Cloudflare

In 2025, Cloudflare has reported that over 5% of global emails were found to be malicious, peaking at nearly 10% in November. Particularly concerning is that more than half of these malicious emails contained deceptive links. This situation poses a significant risk, potentially increasing cyber threats such as phishing attacks and ransomware deployment. For businesses and individual users, addressing these risks is critical, and strengthening security measures is urgently required. In such a climate, email security solutions and filtering technologies are essential. Companies are urged to conduct employee education and training on these issues and to implement the latest security measures. Furthermore, Cloudflare's report prompts considerations regarding the economic impact of increasing cybercrime, making this trend critical for evaluating the future of digital communication and the business environment.
