| Recent Events Suggest Cyber Warfare Can Become New Threat | |||||
| December 2008/January 2009 Issue | |||||
In the recently released quadrennial strategic forecasting report Global Trends 2025: A Transformed World, the National Intelligence Council identifies the “growing use of cyber warfare attacks” as one of the factors that “will constrict U.S. freedom of action.” [1] Moreover, cyber warfare is listed among the non-military means of warfare that “will become more prevalent in conflicts over the next two decades.” [2] These predicted trends call attention to the potential significance of cyber warfare in the arsenals of militarily inferior adversaries that will employ it as part of the asymmetric challenge to U.S. dominance worldwide. As the Internet reaches more distant parts of the globe and national economies of a rapidly increasing number of countries become integrated into the World Wide Web, interest in acquiring both offensive and defensive cyber capabilities by states and non-state actors will only grow. In this regard, Russia and China, as major global exporters of information technology (IT) professionals and depositories of IT talent, could pose the gravest threats.
The severity of security challenges posed by cyber warfare to any given country is largely proportional to the degree of its dependence on modern information and communications
technology. Thus, countries that are more advanced in terms of Internet accessibility, e-commerce, e-banking, etc., possess more vulnerabilities to cyber attack. On the other hand, relatively backward IT states will be considerably less exposed to cyber dangers. While Project Grey Goose did not uncover any Russian government/Hacker connections in its examination of the public Xakep.ru forum or the private StopGeorgia.ru forum, it is not reasonable to conclude that no such connection exists. The historical record shows clear support by members of the Russian government and implied consent in its refusal to intervene or stop the hacker attacks. [14]Another important contribution of Project Grey Goose was that, contrary to a widely held view, it concluded that the cyber assault against Georgian websites did not consist primarily of DDOS attacks. The team led by Carr found evidence suggesting the use of simpler but equally effective SQL injection attacks, which exploit application level vulnerabilities of the MySQL software used by many websites to manage backend databases. These attacks overwhelm the targeted database with millions of junk queries, thereby rendering the corresponding server inoperable. From a hacker’s perspective, SQL attacks provide two main advantages. First, when used in combination with traditional DDOS attacks, they are extremely difficult to detect. Second, SQL injection attacks require far fewer computers to achieve the same objectives as DDOS attacks, which cannot be sustained effectively without botnets. As the Project Grey Goose report notes, the use of the SQL injection attacks “shows moderate technical sophistication, but more importantly, it shows planning, organization, targeted reconnaissance, and evolution of attacks.” [15] In the end, the cyber attacks inflicted little damage because much of Georgia’s economy and critical infrastructure are still not integrated into the Internet. Only about 7 percent of the country’s population has Internet access and, according to some measures, Georgia occupies 74th place out of 234 nations, behind Nigeria, Bangladesh, Bolivia, and El Salvador. [16] Nonetheless, the grassroots campaign waged by the nationalist hacktivists galvanized into action with the help of Russian online hacker forums effectively disrupted the timely dissemination of information by the Georgian government and forced Tbilisi to seek alternative methods for getting its message out to the international community. Case 2: Cyber Attack on Estonia The cardinal difference between the cyber attacks on Georgia and the earlier assault on Estonia is that in the latter case the attacks had a more profound impact because the Estonian economy is fully integrated into the Internet. It would not be an exaggeration to state that this tiny country, with a population of 1.3 million people, has become a marvel in terms of widespread access to state-of-the-art communications technology. In order to appreciate the full extent of Estonia’s evolution as one of the most electronically advanced countries in the world, it is important to note that since November 2005 the Estonian government has shifted its operations to the virtual domain. Cabinet-level meetings are conducted online while documents are signed with e-signatures. As of March 2007, Estonian citizens could even cast their votes in national elections via their PCs. [17] Moreover, in 2007 Estonia was ranked 23rd in e-readiness ratings. Almost 61 percent of the population enjoys online access to its bank accounts, and 95 percent of banking transactions are electronic. [18] Such overwhelming reliance on the Internet was bound to attract the interest of Russian hackers, who were waiting for a pretext to test Estonia’s cyber defenses. That pretext came with the Estonian government’s decision to relocate the monument commemorating the sacrifice of Soviet armed forces in liberating Estonia from the Nazi yoke during World War II. On April 27, 2007, the seemingly innocuous act of relocating the monument from the center of the Estonian capital Tallinn to a military cemetery outside the city sparked protests and riots among Estonia’s Russian minority. These protests were then followed by a barrage of DDOS attacks from Russia. A call for action, complete with specific instructions on how to participate in the DDOS attacks, quickly spread through Russian online chat rooms. Soon Estonian “government websites that normally receive 1,000 visits a day reportedly were receiving 2,000 visits every second.” [19] As a result, the websites of the Ministries of Foreign Affairs and Justice had to shut down, while Prime Minister Andrus Ansip’s Reform Party’s website was defaced with digital graffiti of a Hitler-style moustache scrawled across the Prime Minister’s photo. [20] More importantly, the Russian hacktivists managed to briefly disable the national emergency toll-free phone number 112; luckily, no accidents happened during its downtime. [21] Both the United States and NATO sent teams of computer security experts to help the Estonian authorities cope with the massive wave of DDOS attacks that paralyzed the country’s government websites, banking industry, and media outlets. What struck many network security experts as unusual about the cyber attacks was that they lasted weeks and their intensity was extremely high. Some botnets employed in the DDOS attacks on Estonian websites included up to 100,000 “zombie” PCs. [22] The concerted efforts by its allies eventually stabilized Estonia’s situation, but intermittent cyber attacks on national government websites, including the State Chancellery and Federal Electoral Committee, continued well into the middle of May 2007. [23] The cyber attack on Estonia led NATO to establish the Cooperative Cyber Defense Center in Estonia in May 2008. [24] Although its formal opening is planned for 2009, the Center, with a staff of 30 specialists, became operational in August. [25] The cyber defense center is part of a NATO network of 10 accredited Centers of Excellence dedicated to training representatives from alliance member countries “on technically sophisticated aspects of NATO operations.” [26] However, a recently revealed Estonian spy affair casts serious doubt on the usefulness of this center, at least as it is currently conceived. Case 3: The Herman Simm Affair and Its Possible Fallout In September, Estonian police arrested 61-year old Herman Simm, a high-ranking official at the Estonian Ministry of Defense, whom they accused of passing highly classified information on U.S. missile shield plans and cyber defense to the Russian Foreign Intelligence Service (SVR) in exchange for millions of dollars. [27] Described as the “most serious case of espionage against NATO since the end of Cold War,” the Simm affair demonstrates that the Russian government has undertaken aggressive intelligence gathering operations, particularly in the fields of missile and cyber defense. [28] As the head of the State Secret Protection Office, Simm was responsible for protecting Estonia’s most sensitive secrets. Recruited by the Russians in the late 1980s, Mr. Simm “became a proper agent for the Russian government in the mid-1990s,” according to the head of the Estonian parliamentary oversight commission on security services, Jaanus Rahumaegi. [29] At present, several investigation teams from the European Union (EU) and NATO are working feverishly in Tallinn under the supervision of a U.S. officer to assess the damage. A German official familiar with the investigation bluntly characterized the Russian penetration of NATO caused by Simm as a “catastrophe.” [30] Motivated by greed, Simm operated with his wife, Heete, a lawyer who was previously employed at national police headquarters. Mr. Simm used a converted radio transmitter to schedule meetings with his handler, who posed as a Spanish businessman. Moreover, in 2003, the Estonian Prime Minister issued Simm a diplomatic passport, which allowed him to carry classified documents abroad. [31] It is unknown whether Mr. Simm had any other accomplices, but considering that for many years he oversaw issuance of security clearances for Estonian officials in the intelligence, military, and security agencies, such a possibility cannot be ruled out. Mr. Simm is expected to be arraigned next year. If convicted he faces between three and fifteen years in prison. [32] What is particularly damaging about Mr. Simm’s treachery is that at the Ministry of Defense he was entrusted with the sensitive function of devising information protection systems for both NATO and the EU. In this capacity, Mr. Simm frequently headed the Estonian government delegation in talks on protecting classified data flows both in the EU and NATO. Described as being “at the cutting edge of NATO’s most important new strategic missions: to defend the alliance against cyber-attack,” Mr. Simm has perhaps fatally compromised the NATO Cooperative Cyber Defense Center. [33] In one possible fallout from the Simm affair, U.S. Department of Defense computers sustained a “severe and widespread” electronic attack as recently as the Thanksgiving week of November 24-28. [34] According to the few reports available in open sources, the attack, which may have originated in Russia, was spread by an intrusive piece of malware with the file name agent.btz. It was apparently designed to target military computer networks specifically. The cyber assault affected the networks of U.S. Central Command, including computers in the combat zones in Iraq and Afghanistan. It also penetrated one highly protected classified network. [35] The gravity of the attack prompted the Pentagon leadership to issue a worldwide ban on the use of external computer flash drives, which were blamed for spreading the agent.btz malware from infected computers. [36] This, in turn, complicated information sharing among battlefield commanders in the theater of operations because they often rely on such drives. The seriousness of the challenge was reflected by the fact that the Chairman of the Joint Chiefs of Staff, Admiral Michael G. Mullen, personally briefed President Bush about the malware attack. [37] Meanwhile, in response, the U.S. Strategic Command, which oversees the military’s cyber defenses, elevated its information defense operations with what were described as “enhanced security measures.” [38] Case 4: The Chinese Cyber Threat China could also pose a formidable cyber threat due to a combination of factors, including the sheer number of Chinese Internet users. [39] In its annual congressionally mandated report on the Chinese military, the U.S. Department of Defense cited a number of examples demonstrating the global reach of Chinese cyber intrusions. According to the report, in Germany, the Vice President of the Office for the Protection of Constitution Hans Elmar Remberg openly accused China of carrying out computer network intrusions on an “almost daily” basis. In September 2007, French Secretary-General of National Defense Francis Delon publicly admitted that French government websites had been targeted by Chinese cyber attacks. [40] In November 2007, the director of the British intelligence service MI5, Jonathan Evans, warned representatives of financial services companies that they were targets of Chinese “state-sponsored computer network exploitation.” [41] At the time, it was suspected that Chinese hackers successfully obtained strategic plans and sophisticated risk management systems of Lehman Brothers, Britain’s Bradford & Bingley, and Iceland’s Landsbanki. [42] It appears that as far back as 2005 the Chinese People’s Liberation Army (PLA) took an important step by forming “information warfare units to develop viruses to attack enemy computer systems and networks.” [43] Chinese military thinking in the area of computer network operations (CNO) incorporates different categories of cyber operations, including computer network attack (CNA), computer network exploitation (CNE), and computer network defense (CND) – all of which fall under the umbrella concept of integrated network electronic warfare. [44] In 2007, Chinese hackers believed to be associated with the PLA carried out a notable attack on Pentagon computer networks, which lasted several weeks. They managed to overcome vigorous defense efforts put up by U.S. military computer experts and accessed the unclassified computer system that supports the Secretary of Defense. To avoid further damage, Pentagon IT security specialists were forced to shut down the network to carry out maintenance in an off-line mode. This incident prompted the creation of the National Cyber Investigative Joint Task Force, which is credited with the detection of the most recent Chinese cyber penetration of the White House computer network. The Financial Times reported in early November 2008 that Chinese hackers accessed the White House computer network on a number of occasions to steal e-mail messages between government officials. [45] Because of the closed and authoritarian nature of the Chinese state and tightly regulated Internet use in China, it is difficult to imagine that sizable hacker communities can operate freely there without state oversight and control. Unlike their Russian counterparts, the actions of the Chinese hackers are more focused on achieving specific objectives, which include aggressive acquisition of commercial secrets as well as information on future weapons systems. Despite China’s status as the second largest U.S. trading partner, Beijing’s lack of transparency with regard to its military modernization and overall yearly increases in military expenditures raise Pentagon worries. The sphere of cyber warfare specifically represents “an area of growing concern,” according to the Deputy Assistant Secretary of Defense for East Asia, David Sedney. [46] Conclusion The rapid spread of information and communication technology will only magnify the threat of cyber warfare in years to come. The apparently Russian-based cyber attacks on Estonia and Georgia showed the importance of the emerging concepts of digital citizenship and digital activism, which defy state borders and raise thorny issues of dual (or split) loyalties. Under the cloak of plausible deniability and employment of non-attributable means of communication (i.e. no paper trails), the Kremlin could be tempted to use the vast hacker resources at its disposal to settle scores across the post-Soviet geopolitical space. Moscow’s keen interest in learning Western cyber defenses was once again recently highlighted by the disastrous Simm affair in Estonia. China has been increasingly exhibiting an appetite for industrial espionage and aggressive intelligence gathering through cyber attacks both in the United States and Europe, and Beijing has been actively incorporating cyber warfare elements into its overall defense posture for some time. The United States, as the creator of the Internet, will have to spearhead the formation of a legal framework for this new challenge, complete with definition of vital terms and rules of the game. While the discussion of legal considerations goes beyond the scope of this article, it is obvious that the main tenets of conventional warfare embedded in the Geneva Conventions will have to be reformulated to take account of cyber warfare because it blurs such principles as proportionality, neutrality and distinction. Some semblance of order will have to be injected into the interconnected expanse of the Internet unless we want to witness a spiraling escalation of cyber attacks of increasing sophistication with lethal consequences for unsuspecting masses.
