What are Blended Threats?

Malicious code that is referred to as a blended threat is code that can replicate itself in more than one manner, can have more than one type of trigger, and can have multiple task capabilities. A blended threat is an exploit that combines elements of multiple types of malware and usually employs multiple attack vectors to increase the severity of damage and the speed of contagion.


A blended threat is often able to move around the Internet using e-mail virus capabilities as well as worm capabilities. A blended threat attack can also plant a Trojan on a computer. The trigger can be set off by an e-mail program action or a Web surfing action. Malicious code writers have become sophisticated in blending the characteristics and capabilities of multiple threat types. This is part of the ongoing knowledge-building process in the malicious code–writing community.
