Malware, short for malicious software, (sometimes referred to as pestware) is a software designed to secretly access a computer system without the owner's informed consent. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.
The World Wide Web is a criminals' preferred pathway for spreading malware. Today's web threats use combinations of malware to create infection chains. About one in ten Web pages may contain malicious code.
Wikis and blogs
Attackers may use wikis and blogs to advertise links that lead to malware sites.
Wiki and blog servers can also be attacked directly. Just in 2010, Network Solutions has been hacked and some sites hosting in there became a path to malware and spam.
Targeted SMTP threats
Targeted SMTP threats also represent an emerging attack vector through which malware is propagated. As users adapt to widespread spam attacks, cybercriminals distribute crimewareto target one specific organization or industry, often for financial gain.
HTTP and FTP
