Email Security Threats in 2025: Beyond Spam and Phishing

Email remains the primary attack vector for cybercriminals, but the threats have evolved far beyond simple spam. Here’s what your organisation needs to watch for in 2025.

Emerging Email Threats

Business Email Compromise (BEC)

BEC attacks impersonate executives or business partners to trick employees into transferring funds or sharing sensitive data. These attacks often involve no malware, making them difficult for traditional security tools to detect.

Conversation Hijacking

Attackers insert themselves into existing email threads, making their malicious requests appear legitimate within the context of an ongoing conversation.

QR Code Phishing (Quishing)

Phishing emails containing QR codes that direct victims to malicious websites when scanned with a mobile device, bypassing desktop email security.

AI-Generated Phishing

Large language models are being used to create highly convincing, personalised phishing emails with perfect grammar and contextual relevance.
