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

Increase in Malicious Emails

According to Cloudflare's latest report, over 5% of global emails are malicious as of 2025, peaking at nearly 10% in November. The report notes that more than half of these malicious emails contain deceptive links. The increase in malicious emails can be attributed to cybercriminals employing sophisticated methods that regular users may find difficult to detect. This poses a serious risk to both individuals and corporations, particularly in the form of phishing attacks. Cloudflare's announcement highlights the need for companies to strengthen their security measures, especially through email filtering systems and user education. To protect oneself and one's organization, it is crucial to raise security awareness and implement high-level defense strategies. Cyber attacks are evolving every year, with widespread implications, necessitating ongoing attention to this issue.
