Web 2.0 will up the security ante for enterprises in 2008.
Immediately behind are spam, botnets, event-based attacks/fraud and
attacks on the virtual world. The interconnectedness spawned by Web
2.0 additions like mash-ups, widgets and social networks on the Web
is creating ‘weak links’ or compromised Web sites that
could be exploited to target a larger number of Internet users,
says Websense in its 2008 threat report. Social networking sites
(like MySpace and Facebook) with large numbers of users are most
vulnerable to such attacks. McAfee Avert Labs in its 2008 security
report also warns of a large increase in use of Web 2.0 sites to
distribute malware. 
2008 does not promise relief from spam. According to Vishal Dhupar,
MD, Symantec India, 2008 will see spammers using attachment types
like MP3, flash and more appealing content (or pop culture spam) to
evade traditional blocking systems and lure users into reading
messages. Both Symantec and Websense predict more spam to be
delivered via popular social networking sites. Websense reports
that spammers have started posting URLs of malicious sites inside
forums, blogs and even news sites (especially in their commentary
or ‘talk-back’ sections) to boost their sites’
ranking in search engine results and attract more users to their
sites.
With security measures failing to catch up with technological
advances, voice-related cyber crime will have a free hand in 2008.
Websense predicts that vishing (or the practice of using social
engineering and Voice over IP) to gain personal and financial
information, and voice spam, will combine and increase in 2008. In
fact, with 2007 seeing more than double the number of VoIP security
vulnerabilities vis-à-vis all of 2006, McAfee expects VoIP
attacks to rise by 50 percent in 2008.
With spam evolving and transiting to 2008, can bots be far behind?
An indication of how far the Bot menace has evolved is the
‘Storm’ worm, which created the largest peer-to-peer
botnet ever. “We may see things like phishing sites hosted by
bot zombies,” says Dhupar. 2008 could see a diversified bots
invasion. Symantec’s report talks about the use of bots to
artificially boost traffic to compromised Web sites through the
hijack of browsers, enabling the perpetrator to generate fraudulent
advertising revenue or serve malicious code which could then be
used in subsequent fraudulent activities.
Attacks/frauds that exploit public interest in an event are
expected to grow in 2008. Websense predicts that sites related to
the 2008 Beijing Olympics could see large scale denial-of-service
attacks or be compromised through malware to steal personal or
confidential business information.
2008 will also see intensified efforts on the part of
cybercriminals to target virtual worlds like Second Life and online
gaming. As virtual objects continue to gain real value, criminals,
phishers, spammers and others will look to capitalize on this.
According to McAfee, the number of password-stealing trojans that
targeted online games in 2007 grew faster than the number of
trojans that targeted banks.
