[HIB]Why cybersecurity experts can never rest

The Web threat landscape is becoming increasingly dynamic and opportunistic as hackers continue to adapt to new online functionality and trends, according to a report on online security from Zscaler, a security firm that specializes in cloud computing. “While the goals have not changed, the techniques continue to evolve,” wrote Michael Sutton, the company's vice president of security research, in the "State of the Web" report for the second quarter of 2010. “The attacks that we're seeing are increasingly dynamic in nature, continually shifting locations and swapping out payloads to avoid detection.” Attackers are using social networking functionality, exploiting current events and using techniques such as fast flux to quickly change the Domain Name System resolution for IP addresses, a tactic that allows them to evade blacklists that block malicious sites. The trends are not new, but they illustrate the continued threat posed by increasingly professional criminals with access to a growing kit of malicious tools available in the underground market.
