Several social engineering techniques are used to trick users into opening the infected message. 

The IM worm was first detected in 2001 and was considered harmless until 2006. In 2006 an malicious WMF file known as xmas-2006 FUNNY.jpg was used to spread malware using MSN messenger in the Netherlands. Similar worms were also spread using other instant messaging platforms like Yahoo!, AOL Instant Messenger, ICQ etc.
