While the victim waits for the website to load, the script is already pointing them to a blackhole exploit kit server, where an exploit code starts to execute. A .JAR file is executed, downloading other malicious files into the victim's machine.

Trend Micro™ Smart Protection Network™ protects users from this threat by blocking the spam mail samples, as well as any related malicious URLs and malware.
