Malicious email activity spikes globally, with phishing links and identity deception leading cyber risks
Global email traffic is becoming increasingly dangerous, with new data showing a sharp rise in malicious messages during 2025. Security analysts warn that email remains the primary gateway for cybercrime, putting individuals, businesses, and especially digital asset users at growing risk.
Recent analysis of worldwide email traffic found that over 5% of all emails contained malicious content, meaning more than one in every 20 emails posed a security threat. Alarmingly, this figure surged in November, when nearly 10% of emails were classified as malicious, marking the highest monthly level recorded this year.
Malicious emails are designed to steal credentials, financial data, or digital assets, often resulting in irreversible losses once victims interact with them.
Among all threats detected, deceptive links accounted for more than half of malicious emails. These links redirect users to fraudulent websites that mimic legitimate platforms. Identity deception followed closely, with attackers impersonating trusted contacts through spoofed domains and misleading display names.
Security researchers also found that 25% of HTML email attachments were malicious, while 12% of harmful PDF files were linked to cryptocurrency scams. Certain domain extensions were heavily exploited, with seasonal and generic domains frequently used to bypass filters.
With email-based attacks growing in scale and sophistication, cyber awareness and strong email security practices are now essential to avoid costly and irreversible damage.
