An analyst at the US Central Intelligence Agency (CIA) has said that criminals have been successful in hacking into computer systems via the Internet. In doing so, these criminals have been able to cut the electric supply of several cities in the US.
It was CIA analyst Tom Donahue who disclosed this at a conference of security professional last week. He also offered a few specifics on what exactly went wrong. It appears that criminals had launched online attacks that had disrupted power equipment in a number of regions outside the US. However, he did not mention that exact countries that were affected.
The goal of the attacks was extortion, concluded Donahue.
“We have information, from multiple regions outside the United States, of cyber intrusions into utilities, followed by extortion demands. In at least one case, the disruption caused a power outage affecting multiple cities. We do not known who executed these attacks or why, but all involved intrusions were through the Internet,” he said.
“According to Mr. Donahue, the CIA actively and thoroughly considered the benefits and risks of making this information public, and came down on the side of disclosure,” SANS Institute said in a statement.

Visualization of the various routes through a portion of the Internet
The Internet is a global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. In addition it supports popular services such as online chat, file transfer and file sharing, gaming, commerce, social networking, publishing, video on demand, and teleconferencing and telecommunications. Voice over Internet Protocol (VoIP) applications allow person-to-person communication via voice and video.
The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks. This research and a period of civilian funding of a new U.S. backbone by the National Science Foundation spawned worldwide participation in the development of new networking technologies and led to the commercialization of an international network in the mid 1990s, and resulted in the following popularization of countless applications in virtually every aspect of modern human life. As of 2009, an estimated quarter of Earth's population uses the services of the Internet.
