What is malware in email?

Email malware is malicious software delivered through messages. Delivery methods include: attachments containing malware directly, links to malware downloads, and embedded exploits targeting email client vulnerabilities.

Common malware types via email: ransomware encrypting victim files for extortion, trojans providing remote access to attackers, information stealers harvesting credentials and data, and worms spreading through contact lists.

Email remains primary malware delivery vector because it reaches humans directly, bypassing network security. Technical defenses (scanning, sandboxing) plus user awareness (not opening suspicious attachments) provide protection.
