4chan

4chan

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.

Stuxnet

Iran was subjected to cyber attacks on June 2010 when its nuclear facility in Natanz was infected by Stuxnet, a cyber worm that was believed to be a combined effort of Israel and the United States, though no one claimed responsibility for its inception. The worm destroyed Tehran’s 1000 nuclear centrifuges and set back the country’s atomic program by at least two years, as it spread beyond the plant and infected over 60,000 computers as well. The Iranian government was also accused of its own cyber attacks to the United States, Israel and other countries in the Gulf Arabs, including their alleged involvement in the hacking of American banks in 2012.
