Blended threats are bundles of malicious programs that combine the functionality of different types of malware such as Trojans, worms, and backdoors. A blended threat often involves an infection chain that begins with a user visiting a website and then diverted to a malicious URL. After this, social engineering lures will lead the user to download a malicious file which will continue to download additional malicious files. By using multiple methods and techniques, cybercriminals are able to quickly and surreptitiously spread threats.
Layered security platforms that provide in-depth defense and continuous monitoring are best used against blended threats.
