An English-language image board website used for posting pictures and discussion of the Japanese manga and anime, 4chan was launched on October 1, 2003 by a bored 15-year-old student from New York City named Christopher Poole. Since users of the website can post anonymously, experts believed that its users were able to pull off the highest collective actions in the history of the internet. One of their victims includes Hal Turner, who was raided with DDoS attacks and prank calling in his radio show from December 2006 to 2007. Later that year, the private Yahoo!Mail account of Sarah Palin, who was running as a Republican vice presidential candidate in the 2008 US presidential election, was hacked by a 4chan user, resulting in criticisms in using private email accounts for government work.
15. The Spamhaus Project
Considered as the biggest cyber attack in history, Spamhaus, a filtering service used to weed out spam emails, was subjected to cyber attacks wherein home and business broadband router owners became unsuspecting participants when their routers have been threatened. Thousands of Britons used Spamhaus on a daily basis determine whether or not to accept incoming mails. On March 18, 2013, Spamhaus added Cyberbunker to its blacklisted sites and Cyberbunker and other hosting companies retaliated by hiring hackers to put up botnets, which also exploited home and broadband routers, to shut down Spamhaus’ system.
TJX, a Massachusetts-based retailing company and owner of TJ Maxx and Marshalls, was just one of the many retailer companies hacked by Albert Gonzales and a group of hackers from the Shadowcrew. They were able tosiphon45 million credit and debit card information, which they used to fund their million-dollar shopping spree of electronic goods from Wal-Mart. The data breach has resulted in $250 million in damages as Gonzales and 10 of his crew seek their targets while wardriving and looking for vulnerabilities in wireless networks along US Route 1 in Miami.
5. The Estonian Cyberwar
The government of Estonia was subjected to cyber terrorism on April 27, 2007 by the Nashi, a pro-Kremlin group from Transnistria. One of the largest after Titan Rain, they employed a number of techniques such as ping floods and botnets to penetrate and take down key government websites rendering them useless. Their method was so complicated that the Estonian government believed that they might have had aids from the Russian government. What triggered these attacks was an important icon to the Russian people, the Bronze Soldier of Tallinn, an elaborate Soviet-era war grave marker and the war graves that were relocated by the Estonian government.
