View source for DuQu (malware)

==Technical Specifics==
Duqu is often delivered as a [[Microsoft]] [[Word]] document.  Once opened, it exploits what was at the time of release a [[Zero-day (computing)|zero-day vulnerability]] (that is, one which was completely unknown) in font handling.  Once a computer is infected, it opens a "back door" and begins downloading the main content of the malware.  It also has rootkit functionality, so it can run nearly invisibly on the host computer.<ref>https://www.symantec.com/security_response/writeup.jsp?docid=2011-101814-1119-99</ref><ref>https://securelist.com/blog/incidents/32463/duqu-faq-33</ref>
