HACKING

        

                                          

While breaching privacy to detect cybercrime works well when the crimes involve the theft and misuse of information, ranging from credit card numbers and personal data to file sharing of various commodities—music, video, or child pornography—what of crimes that attempt to wreak havoc on the very workings of the machines that make up the network? The story of hacking actually goes back to the 1950s, when a group of phreaks (short for “phone freaks”) began to hijack portions of the world’s telephone networks, making unauthorized long-distance calls and setting up special “party lines” for fellow phreaks. With the proliferation of computer bulletin board systems (BBSs) in the late 1970s, the informal phreaking culture began to coalesce into quasi-organized groups of individuals who graduated from the telephone network to “hacking” corporate and government computer network systems.

Although the term hacker predates computers and was used as early as the mid-1950s in connection with electronic hobbyists, the first recorded instance of its use in connection with computer programmers who were adept at writing, or “hacking,” computer code seems to have been in a 1963 article in a student newspaper at the Massachusetts Institute of Technology (MIT). After the first computer systems were linked to multiple users through telephone lines in the early 1960s, hacker came to refer to individuals who gained unauthorized access to computer networks, whether from another computer network or, as personal computers became available, from their own computer systems. Although it is outside the scope of this article to discuss hacker culture, most hackers have not been criminals in the sense of being vandals or of seeking illicit financial rewards. Instead, most have been young people driven by intellectual curiosity; many of these people have gone on to become computer security architects. However, as some hackers sought notoriety among their peers, their exploits led to clear-cut crimes. In particular, hackers began breaking into computer systems and then bragging to one another about their exploits, sharing pilfered documents as trophies to prove their boasts. These exploits grew as hackers not only broke into but sometimes took control of government and corporate computer networks.

One such criminal was Kevin Mitnick, the first hacker to make the “most wanted list” of the U.S. Federal Bureau of Investigation (FBI). He allegedly broke into the North American Aerospace Defense Command (NORAD) computer in 1981, when he was 17 years old, a feat that brought to the fore the gravity of the threat posed by such security breaches. Concern with hacking contributed first to an overhaul of federal sentencing in the United States, with the 1984 Comprehensive Crime Control Act and then with the Computer Fraud and Abuse Act of 1986.

One of the largest known case of computer hacking was discovered in late March 2009. It involved government and private computers in at least 103 countries. The worldwide spy network known as Ghost Net was discovered by researchers at the University of Toronto, who had been asked by representatives of the Dalai Lama to investigate the exiled Tibetan leader’s computers for possible malware. In addition to finding out that the Dalai Lama’s computers were compromised, the researchers discovered that Ghost Net had infiltrated more than a thousand computers around the world. The highest concentration of compromised systems were within embassies and foreign affairs bureaus of or located in South Asian and Southeast Asian countries. Reportedly, the computers were infected by users who opened e-mail attachments or clicked on Web page links. Once infected with the Ghost Net malware, the computers began “phishing” for files throughout the local network—even turning on cameras and video-recording devices for remote monitoring. Three control servers that ran the malware were located in Hainan, Guangdong, and Sichuan provinces in China, and a fourth server was located in California.

The scale of hacking crimes is among the most difficult to assess because the victims often prefer not to report the crimes—sometimes out of embarrassment or fear of further security breaches. Officials estimate, however, that hacking costs the world economy billions of dollars annually. Hacking is not always an outside job—a related criminal endeavor involves individuals within corporations or government bureaucracies deliberately altering database records for either profit or political objectives. The greatest losses stem from the theft of proprietary information, sometimes followed up by the extortion of money from the original owner for the data’s return. In this sense, hacking is old-fashioned industrial espionage by other means.

In late March 2007 the Idaho National Laboratory released a video demonstrating what catastrophic damage could result from utility systems being compromised by hackers. Several utilities responded by giving the U.S. government permission to run an audit on their systems. In March 2009 the results began to leak out with a report in The Wall Street Journal. In particular, the report indicated that hackers had installed software in some computers that would have enabled them to disrupt electrical services. Homeland Security spokeswoman Amy affirmed that no disruptions had occurred, though further audits of electric, water, sewage, and other utilities would continue.
