In February 2003, the Symantec Internet Security Threat Report said that during the second part of 2002, the highest rates for computer exploits targeted critical infrastructure industry companies, such as energy, financial services, and power, a finding that helped escalate the fears of an imminent cyber Apocalypse.
The findings of the more recent report for the period between July 1, 2005, and December 31, 2005, indicate that the threat landscape is now dominated by attacks and malicious code that are used to commit cybercrime. Attackers have moved away from large, multipurpose attacks on network perimeters and have moved toward smaller, more focused attacks on client-side targets.
