Owen Thor Walker (online pseudonym AKILL) is a computer hacker living in New Zealand, who was discharged without conviction despite pleading guilty to several charges of 'cybercrime'. [1] [2] In 2008 he admitted to being the ringleader of an international hacking organization estimated to have caused $26 million worth of damage. [1] [3]
Walker was home-schooled from the age of 13. [4] [5] He received no formal computer training, instead teaching himself programming and encryption. [1] [5] [6] He had been diagnosed with Asperger's syndrome. [7]
Walker was arrested under sections 248-252 of New Zealand's Crime Act after international investigations by the FBI found him to be involved in an attack on the computer network of the University of Pennsylvania. [8] The attack was orchestrated via a botnet established by Walker, using servers he exploited and rented, the majority of which were located in Malaysia. [9]
He pleaded guilty to his connection in the crime, was fined for the cost of the damage to the University of Pennsylvania computer and was discharged without conviction, the presiding judge concluded that a conviction would only harm his future. [10]
In 2008 he was hired by TelstraClear, the New Zealand subsidiary of Australian telecommunications company Telstra, to work with their security division DMZGlobal.

Cybercrime encompasses a wide range of criminal activities that are carried out using digital devices and/or networks. These crimes involve the use of technology to commit fraud, identity theft, data breaches, computer viruses, scams, and expanded upon in other malicious acts. Cybercriminals exploit vulnerabilities in computer systems and networks to gain unauthorized access, steal sensitive information, disrupt services, and cause financial or reputational harm to individuals, organizations, and governments.
In computing, a zombie is a computer connected to the Internet that has been compromised by a hacker via a computer virus, computer worm, or trojan horse program and can be used to perform malicious tasks under the remote direction of the hacker. Zombie computers often coordinate together in a botnet controlled by the hacker, and are used for activities such as spreading e-mail spam and launching distributed denial-of-service attacks against web servers. Most victims are unaware that their computers have become zombies. The concept is similar to the zombie of Haitian Voodoo folklore, which refers to a corpse resurrected by a sorcerer via magic and enslaved to the sorcerer's commands, having no free will of its own. A coordinated DDoS attack by multiple botnet machines also resembles a "zombie horde attack", as depicted in fictional zombie films.
A botnet is a group of Internet-connected devices, each of which runs one or more bots. Botnets can be used to perform distributed denial-of-service (DDoS) attacks, steal data, send spam, and allow the attacker to access the device and its connection. The owner can control the botnet using command and control (C&C) software. The word "botnet" is a portmanteau of the words "robot" and "network". The term is usually used with a negative or malicious connotation.
Cyberterrorism is the use of the Internet to conduct violent acts that result in, or threaten, the loss of life or significant bodily harm, in order to achieve political or ideological gains through threat or intimidation. Acts of deliberate, large-scale disruption of computer networks, especially of personal computers attached to the Internet by means of tools such as computer viruses, computer worms, phishing, malicious software, hardware methods, and programming scripts can all be forms of internet terrorism. Cyberterrorism is a controversial term. Some authors opt for a very narrow definition, relating to deployment by known terrorist organizations of disruption attacks against information systems for the primary purpose of creating alarm, panic, or physical disruption. Other authors prefer a broader definition, which includes cybercrime. Participating in a cyberattack affects the terror threat perception, even if it isn't done with a violent approach. By some definitions, it might be difficult to distinguish which instances of online activities are cyberterrorism or cybercrime.
Rizon is an Internet Relay Chat (IRC) network. The IRC network itself ranks number 5 among the largest IRC networks. Rizon is popular with many anime fansubbing groups who work online, many of whom provide their content through XDCC via IRC bots in their distribution channels. It is also used by many users of eRepublik as a means of communication. File sharing of other copyrighted material such as Warez is also common in some channels on the network.
The Computer Misuse Act 1990 is an act of the Parliament of the United Kingdom, introduced partly in response to the decision in R v Gold & Schifreen (1988) 1 AC 1063. Critics of the bill complained that it was introduced hastily, was poorly thought out, and that intention was often difficult to prove, with the bill inadequately differentiating "joyriding" hackers like Gold and Schifreen from serious computer criminals. The Act has nonetheless become a model from which several other countries, including Canada and the Republic of Ireland, have drawn inspiration when subsequently drafting their own information security laws, as it is seen "as a robust and flexible piece of legislation in terms of dealing with cybercrime". Several amendments have been passed to keep the Act up to date.
Brian Krebs is an American journalist and investigative reporter. He is best known for his coverage of profit-seeking cybercriminals.

Beginning on 27 April 2007, a series of cyberattacks targeted websites of Estonian organizations, including Estonian parliament, banks, ministries, newspapers and broadcasters, amid the country's disagreement with Russia about the relocation of the Bronze Soldier of Tallinn, an elaborate Soviet-era grave marker, as well as war graves in Tallinn. Most of the attacks that had any influence on the general public were distributed denial of service type attacks ranging from single individuals using various methods like ping floods to expensive rentals of botnets usually used for spam distribution. Spamming of bigger news portals commentaries and defacements including that of the Estonian Reform Party website also occurred. Research has also shown that large conflicts took place to edit the English-language version of the Bronze Soldier's Wikipedia page.
Operation: Bot Roast is an operation by the FBI to track down bot herders, crackers, or virus coders who install malicious software on computers through the Internet without the owners' knowledge, which turns the computer into a zombie computer that then sends out spam to other computers from the compromised computer, making a botnet or network of bot infected computers. The operation was launched because the vast scale of botnet resources poses a threat to national security.
Kiwicon is a New Zealand computer security conference held annually in Wellington from 2007. It brings together a variety of people interested in information security. Representatives of government agencies and corporations attend, along with hackers.
Akbot was a computer virus that infected an estimated 1.3 million computers and added them to a botnet. It was created by an 18-year-old named Owen Walker, who was charged but unconvicted in 2008.

Zeus is a Trojan horse malware package that runs on versions of Microsoft Windows. It is often used to steal banking information by man-in-the-browser keystroke logging and form grabbing. Zeus is spread mainly through drive-by downloads and phishing schemes. First identified in July 2007 when it was used to steal information from the United States Department of Transportation, it became more widespread in March 2009. In June 2009 security company Prevx discovered that Zeus had compromised over 74,000 FTP accounts on websites of such companies as the Bank of America, NASA, Monster.com, ABC, Oracle, Play.com, Cisco, Amazon, and BusinessWeek. Similarly to Koobface, Zeus has also been used to trick victims of technical support scams into giving the scam artists money through pop-up messages that claim the user has a virus, when in reality they might have no viruses at all. The scammers may use programs such as Command prompt or Event viewer to make the user believe that their computer is infected.
The February 2010 Australian cyberattacks were a series of denial-of-service attacks conducted by the Anonymous online community against the Australian government in response to proposed web censorship regulations. Operation Titstorm was the name given to the cyber attacks by the perpetrators. They resulted in lapses of access to government websites on 10 and 11 February 2010. This was accompanied by emails, faxes, and phone calls harassing government offices. The actual size of the attack and number of perpetrators involved is unknown but it was estimated that the number of systems involved ranged from the hundreds to the thousands. The amount of traffic caused disruption on multiple government websites.
The Mariposa botnet, discovered December 2008, is a botnet mainly involved in cyberscamming and denial-of-service attacks. Before the botnet itself was dismantled on 23 December 2009, it consisted of up to 12 million unique IP addresses or up to 1 million individual zombie computers infected with the "Butterfly Bot", making it one of the largest known botnets.
