How does that compare to a denial of service (DoS) attack?Ī DoS (denial of service) attack is an attempt to make a computer resource unavailable for its intended users by a single attack entity. The purpose for such attacks, however, can vary widely. To exhaust network bandwidth, server resources, or applications in such a way that legitimate users cannot access a site.

Attackers take advantage of security vulnerabilities to control numerous devices using command and control software. DDoS attackers often leverage the use of a botnet-a group of hijacked internet-connected devices to carry out large scale attacks. "In the past you had to have a certain amount of technical skill to participate, but now anyone can."įor security practitioners the big story within the pro-Wikileak and LOIC attacks may not have much to do about Wikileaks and the legalities or the politics of it all - and everything to do about how swiftly, and easily, online attackers can be called into action against any target they wish.What is a distributed denial-of-service (DDoS) attack?Ī distributed denial-of-service (DDoS) attack is when multiple entities are operating together to attack one target. This is reflected in the many crimeware systems available in the underground, which includes DDOS, do-it-yourself botnet kits (Zeus, Spyeye, and many others) as well as exploit kits," he said.

You don't need to know anything to launch a successful attack anymore," said Corman.Īnyone on the receiving end of a LOIC packet burst would be sure to agree, and how technically savvy the attacker happens to be is made mute by the ease and power of the attack.Ĭox agrees: "The attacker landscape is moving more toward "point-and-click" attack and exploitation tools. There's also the malware kits that make obfuscating malware or building botnets trivial. Just consider how powerful tools like Metasploit have become. "However, I don't think the casual attacker exists any more. "There is a false belief that we are fending off casual attackers," said Joshua Corman, research director, enterprise security at the 451 Group. "It also has the ability to be remotely controlled by a central IRC server, so that more technically competent operators can direct attacks en masse at targets, regardless of the participant's technical knowledge."

It is designed so someone with little or no technical knowledge can quickly download and install it, and participate in DDoS activities," said Alex Cox, principal analyst at security firm NetWitness. What is new is the ease of which a tool such as LOIC can be put into action. They have been socializing on message boards and instantly communicating in Internet Relay Chat for many years. Such attacks being highly connected isn't new, either. Since the launch of the attacks, LOIC has been downloaded nearly 70,000 times.Ĭyber protestors engaging in digital rioting such as web-site defacements, and denial-of-service attacks, and even inserting messages in malware have existed for some time. Those participating in the pro-Wikileaks riots could operate on their own, or choose to connect their system to the "LOIC Hivemind" voluntary botnet that is centrally controlled by those behind Operation Payback.
