Cyberattack
In computers and computer networks an attack is any attempt to expose, alter, disable, destroy, steal or gain unauthorized access to or make unauthorized use of an asset. A cyberattack is any type of offensive maneuver that targets computer information systems, infrastructures, computer networks, or personal computer devices. An attacker is a person or process that attempts to access data, functions or other restricted areas of the system without authorization, potentially with malicious intent. Depending on context, cyberattacks can be part of cyberwarfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, society or organizations, and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyberweapon.
A cyberattack may steal, alter, or destroy a specified target by hacking into a susceptible system. Cyberattacks can range from installing spyware on a personal computer to attempting to destroy the infrastructure of entire nations. Legal experts are seeking to limit the use of the term to incidents causing physical damage, distinguishing it from the more routine data breaches and broader hacking activities.
Cyberattacks have become increasingly sophisticated and dangerous.
User behavior analytics and SIEM can be used to help prevent these attacks.
Definitions
Since the late 1980s cyberattacks have evolved several times to use innovations in information technology as vectors for committing cybercrimes. In recent years, the scale and robustness of cyberattacks has increased rapidly, as observed by the World Economic Forum in its 2018 report: "Offensive cyber capabilities are developing more rapidly than our ability to deal with hostile incidents."In May 2000, the Internet Engineering Task Force defined attack in RFC 2828 as:
CNSS Instruction No. 4009 dated 26 April 2010 by Committee on National Security Systems of the United States of America defines an attack as:
The increasing dependency of modern society on information and computer networks has led to new terms like cyber attack and cyberwarfare.
CNSS Instruction No. 4009 define a cyber attack as:
As cars begin to adopt more technology, cyber attacks are becoming a security threat to automobiles.
Prevalence
In the first six months of 2017, two billion data records were stolen or impacted by cyber attacks, and ransomware payments reached, double that in 2016.Cyberwarfare and cyberterrorism
Cyberwarfare utilizes techniques of defending and attacking information and computer networks that inhabit cyberspace, often through a prolonged cyber campaign or series of related campaigns. It denies an opponent's ability to do the same, while employing technological instruments of war to attack an opponent's critical computer systems. Cyberterrorism, on the other hand, is "the use of computer network tools to shut down critical national infrastructures or to coerce or intimidate a government or civilian population". That means the end result of both cyberwarfare and cyberterrorism is the same, to damage critical infrastructures and computer systems linked together within the confines of cyberspace.The financial crime expert Veit Buetterlin explained that organizations, including state actors, which cannot finance themselves through trade because of imposed sanctions, conduct cyber attacks on banks to generate funds.
Factors
Three factors contribute to why cyber-attacks are launched against a state or an individual: the fear factor, spectacularity factor, and vulnerability factor.Spectacularity factor
The spectacularity factor is a measure of the actual damage achieved by an attack, meaning that the attack creates direct losses and garners negative publicity. On 8 February 2000, a Denial of Service attack severely reduced traffic to many major sites, including Amazon, Buy.com, CNN, and eBay. Amazon reportedly estimated the loss of business at $600,000.Vulnerability factor
Vulnerability factor exploits how vulnerable an organization or government establishment is to cyber-attacks. Organizations without maintenance systems might be running on old servers which are more vulnerable than updated systems. An organization can be vulnerable to a denial of service attack and a government establishment can be defaced on a web page. A computer network attack disrupts the integrity or authenticity of data, usually through malicious code that alters program logic that controls data, leading to errors in output.Professional hackers to cyberterrorists
Professional hackers, either working on their own or employed by government agencies or the military, can find computer systems with vulnerabilities lacking the appropriate security software. Once those vulnerabilities are found, they can infect systems with malicious code and then remotely control the system or computer by sending commands to view content or to disrupt other computers. There needs to be a pre-existing system flaw within the computer such as no antivirus protection or faulty system configuration for the viral code to work.Many professional hackers will promote themselves to cyberterrorists, where a new set of rules govern their actions. Cyberterrorists have premeditated plans and their attacks are not born of rage. They need to develop their plans step-by-step and acquire the appropriate software to carry out an attack. They usually have political agendas, targeting political structures. Cyberterrorists are hackers with a political motivation, their attacks can impact political structure through this corruption and destruction. They also target civilians, civilian interests and civilian installations. As previously stated cyberterrorists attack persons or property and cause enough harm to generate fear.
Types of attack
An attack can be active or passive.An attack can be perpetrated by an insider or from outside the organization;
A resource, called an asset, can have one or more vulnerabilities that can be exploited by a threat agent in a threat action. As a result, the confidentiality, integrity or availability of resources may be compromised. Potentially, the damage may extend to resources in addition to the one initially identified as vulnerable, including further resources of the organization, and the resources of other involved parties.
The so-called CIA triad is the basis of information security.
The attack can be active when it attempts to alter system resources or affect their operation: so it compromises integrity or availability. A "passive attack" attempts to learn or make use of information from the system but does not affect system resources: so it compromises confidentiality.
A threat is a potential for violation of security, which exists when there is a circumstance, capability, action or event that could breach security and cause harm. That is, a threat is a possible danger that might exploit a vulnerability. A threat can be either "intentional" or "accidental".
A set of policies concerned with information security management, the information security management systems, has been developed to manage, according to risk management principles, the countermeasures in order to accomplish to a security strategy set up following rules and regulations applicable in a country.
An attack should led to a security incident i.e. a security event that involves a security violation. In other words, a security-relevant system event in which the system's security policy is disobeyed or otherwise breached.
The overall picture represents the risk factors of the risk scenario.
An organization should make steps to detect, classify and manage security incidents. The first logical step is to set up an incident response plan and eventually a computer emergency response team.
In order to detect attacks, a number of countermeasures can be set up at organizational, procedural and technical levels. Computer emergency response team, information technology security audit and intrusion detection system are examples of these.
An attack usually is perpetrated by someone with bad intentions: black hatted attacks falls in this category, while other perform penetration testing on an organization information system to find out if all foreseen controls are in place.
The attacks can be classified according to their origin: i.e. if it is conducted using one or more computers: in the last case is called a distributed attack. Botnets are used to conduct distributed attacks.
Other classifications are according to the procedures used or the type of vulnerabilities exploited: attacks can be concentrated on network mechanisms or host features.
Some attacks are physical: i.e. theft or damage of computers and other equipment. Others are attempts to force changes in the logic used by computers or network protocols in order to achieve unforeseen result but useful for the attacker. Software used to for logical attacks on computers is called malware.
The following is a partial short list of attacks:
- Passive
- * Computer and network surveillance
- * Network
- ** Wiretapping
- ** Fiber tapping
- ** Port scan
- ** Idle scan
- * Host
- ** Keystroke logging
- ** Data scraping

- **DDos or Distributed Denial of service attack is an attempt made by the hacker to block access to a server or a website that is connected to the Internet. This is achieved using multiple computerized systems, which overloads the target system with requests, making it incapable of responding to any query.
- * Spoofing
- * Mixed threat attack
- * Network

- ** Buffer overflow
- ** Heap overflow
- ** Stack overflow
- ** Format string attack
In detail, there are a number of techniques to utilize in cyber-attacks and a variety of ways to administer them to individuals or establishments on a broader scale. Attacks are broken down into two categories: syntactic attacks and semantic attacks. Syntactic attacks are straightforward; it is considered malicious software which includes viruses, worms, and Trojan horses.
Syntactic attacks
Viruses
A virus is a self-replicating program that can attach itself to another program or file in order to reproduce. The virus can hide in unlikely locations in the memory of a computer system and attach itself to whatever file it sees fit to execute its code. It can also change its digital footprint each time it replicates making it harder to track down in the computer.Worms
A worm does not need another file or program to copy itself; it is a self-sustaining running program. Worms replicate over a network using protocols. The latest incarnation of worms make use of known vulnerabilities in systems to penetrate, execute their code, and replicate to other systems such as the Code Red II worm that infected more than 259 000 systems in less than 14 hours. On a much larger scale, worms can be designed for industrial espionage to monitor and collect server and traffic activities then transmit it back to its creator.Trojan horses
A Trojan horse is designed to perform legitimate tasks but it also performs unknown and unwanted activity. It can be the basis of many viruses and worms installing onto the computer as keyboard loggers and backdoor software. In a commercial sense, Trojans can be imbedded in trial versions of software and can gather additional intelligence about the target without the person even knowing it happening. All three of these are likely to attack an individual and establishment through emails, web browsers, chat clients, remote software, and updates.Semantic attacks
Semantic attack is the modification and dissemination of correct and incorrect information. Information modified could have been done without the use of computers even though new opportunities can be found by using them. To set someone into the wrong direction or to cover your tracks, the dissemination of incorrect information can be utilized.India and Pakistan
There were two such instances between India and Pakistan that involved cyberspace conflicts, started in 1990s. Earlier cyber attacks came to known as early as in 1999. Since then, India and Pakistan were engaged in a long-term dispute over Kashmir which moved into cyberspace. Historical accounts indicated that each country's hackers have been repeatedly involved in attacking each other's computing database system. The number of attacks has grown yearly: 45 in 1999, 133 in 2000, 275 by the end of August 2001. In 2010, Indian hackers laid a cyber attack at least 36 government database websites going by the name "Indian Cyber Army". In 2013, Indian hackers hacked the official website of Election Commission of Pakistan in an attempt to retrieve sensitive database information. In retaliation, Pakistani hackers, calling themselves "True Cyber Army" hacked and defaced ~1,059 websites of Indian election bodies.According to the media, Pakistan's has been working on effective cyber security system, in a program called the "Cyber Secure Pakistan". The program was launched in April 2013 by Pakistan Information Security Association and the program has expanded to country's universities.
Cyberattacks by and against countries
Within cyberwarfare, the individual must recognize the state actors involved in committing these cyber-attacks against one another. The two predominant players that will be discussed is the age-old comparison of East versus West, China's cyber capabilities compared to United States' capabilities. There are many other state and non-state actors involved in cyberwarfare, such as Russia, Iran, Iraq, and Al Qaeda; since China and the U.S. are leading the foreground in cyberwarfare capabilities, they will be the only two state actors discussed.But in Q2 2013, Akamai Technologies reported that Indonesia toppled China with portion 38 percent of cyber attack, a high increase from 21 percent portion in previous quarter. China set 33 percent and US set at 6.9 percent. 79 percent of attack came from Asia Pacific region. Indonesia dominated the attacking to ports 80 and 443 by about 90 percent.
China
China's People's Liberation Army has developed a strategy called "Integrated Network Electronic Warfare" which guides computer network operations and cyberwarfare tools. This strategy helps link together network warfare tools and electronic warfare weapons against an opponent's information systems during conflict. They believe the fundamentals for achieving success is about seizing control of an opponent's information flow and establishing information dominance. The Science of Military and The Science of Campaigns both identify enemy logistics systems networks as the highest priority for cyber-attacks and states that cyberwarfare must mark the start if a campaign, used properly, can enable overall operational success. Focusing on attacking the opponent's infrastructure to disrupt transmissions and processes of information that dictate decision-making operations, the PLA would secure cyber dominance over their adversary. The predominant techniques that would be utilized during a conflict to gain the upper hand are as follows, the PLA would strike with electronic jammers, electronic deception and suppression techniques to interrupt the transfer processes of information. They would launch virus attacks or hacking techniques to sabotage information processes, all in the hopes of destroying enemy information platforms and facilities. The PLA's Science of Campaigns noted that one role for cyberwarfare is to create windows of opportunity for other forces to operate without detection or with a lowered risk of counterattack by exploiting the enemy's periods of "blindness", "deafness" or "paralysis" created by cyber-attacks. That is one of the main focal points of cyberwarefare, to be able to weaken your enemy to the full extent possible so that your physical offensive will have a higher percentage of success.The PLA conduct regular training exercises in a variety of environments emphasizing the use of cyberwarfare tactics and techniques in countering such tactics if it is employed against them. Faculty research has been focusing on designs for rootkit usage and detection for their Kylin Operating System which helps to further train these individuals' cyberwarfare techniques. China perceives cyberwarfare as a deterrent to nuclear weapons, possessing the ability for greater precision, leaving fewer casualties, and allowing for long ranged attacks.
Estonia
The 2007 cyberattacks on Estonia were a series of cyberattacks which began on 27 April 2007 and targeted websites of Estonian organizations, including Estonian parliament, banks, ministries, newspapers and broadcasters, amid the country's disagreement with Russia about the relocation of the Bronze Soldier of Tallinn, an elaborate Soviet-era grave marker, as well as war graves in Tallinn. The attacks triggered a number of military organizations around the world to reconsider the importance of network security to modern military doctrine. The direct result of the cyberattacks was the creation of the NATO Cooperative Cyber Defence Centre of Excellence in Tallinn.Ethiopia
In an extension of a bilateral dispute between Ethiopia and Egypt over the Grand Ethiopian Renaissance Dam, Ethiopian government websites have been hacked by the Egypt-based hackers in June 2020.Iran
On 8 February 2020, the telecommunication network of Iran witnessed extensive disruptions at 11:44 a.m. local time, which lasted for about an hour. The Ministry of Information and Communications Technology of Iran confirmed it as a Distributed Denial of Service attack. The Iranian authorities activated the "Digital Fortress" cyber-defense mechanism to repel. Also known as DZHAFA, it led to a drop of 75 percent in the national internet connectivity.Israel
In April 2020, there were attempts to hack into Israel's water infrastructure of the Sharon central region by Iran, which was thwarted by Israeli cyber defenses. The cyberattack intended to introduce dangerous levels of chlorine into the Israeli water supply.North Korea
Russia
During the 2018 FIFA World Cup, Russia countered and stopped around 25 million cyber attacks on IT Infrastructure.In June 2019, Russia has conceded that it is "possible" its electrical grid is under cyberattack by the United States. The New York Times reported that American hackers from the United States Cyber Command planted malware potentially capable of disrupting the Russian electrical grid.
Ukraine
A series of powerful cyber attacks began 27 June 2017 that swamped websites of Ukrainian organizations, including banks, ministries, newspapers and electricity firms.United Arab Emirates
In 2019, Reuters reported that United Arab Emirates launched a series of cyberattacks on its political opponents, journalists, and human rights activists under Project Raven, on an espionage platform namely Karma. The team included ex-US intelligence agents. Project Raven commenced in 2009 and was planned to be continued for the coming ten years.United States
In the West, the United States provides a different "tone of voice" when cyberwarfare is on the tip of everyone's tongue. The United States provides security plans strictly in the response to cyberwarfare, basically going on the defensive when they are being attacked by devious cyber methods. In the U.S., the responsibility of cybersecurity is divided between the Department of Homeland Security, the Federal Bureau of Investigation, and the Department of Defense. In recent years, a new department was created to specifically tend to cyber threats, this department is known as Cyber Command. Cyber Command is a military subcommand under US Strategic Command and is responsible for dealing with threats to the military cyber infrastructure. Cyber Command's service elements include Army Forces Cyber Command, the Twenty-fourth Air Force, Fleet Cyber Command and Marine Forces Cyber Command. It ensures that the President can navigate and control information systems and that he also has military options available when defense of the nation needs to be enacted in cyberspace. Individuals at Cyber Command must pay attention to state and non-state actors who are developing cyberwarfare capabilities in conducting cyber espionage and other cyber-attacks against the nation and its allies. Cyber Command seeks to be a deterrence factor to dissuade potential adversaries from attacking the U.S., while being a multi-faceted department in conducting cyber operations of its own.Three prominent events took place which may have been catalysts in the creation of the idea of Cyber Command. There was a failure of critical infrastructure reported by the CIA where malicious activities against information technology systems disrupted electrical power capabilities overseas. This resulted in multi-city power outages across multiple regions. The second event was the exploitation of global financial services. In November 2008, an international bank had a compromised payment processor that allowed fraudulent transactions to be made at more than 130 automated teller machines in 49 cities within a 30-minute period. The last event was the systemic loss of U.S. economic value when an industry in 2008 estimated $1 trillion in losses of intellectual property to data theft. Even though all these events were internal catastrophes, they were very real in nature, meaning nothing can stop state or non-state actors to do the same thing on an even grander scale. Other initiatives like the Cyber Training Advisory Council were created to improve the quality, efficiency, and sufficiency of training for computer network defense, attack, and exploitation of enemy cyber operations.
On both ends of the spectrum, East and West nations show a "sword and shield" contrast in ideals. The Chinese have a more offensive minded idea for cyberwarfare, trying to get the pre-emptive strike in the early stages of conflict to gain the upper-hand. In the U.S. there are more reactionary measures being taken at creating systems with impenetrable barriers to protect the nation and its civilians from cyber-attacks.
According to Homeland Preparedness News, many mid-sized U.S. companies have a difficult time defending their systems against cyber attacks. Around 80 percent of assets vulnerable to a cyber attack are owned by private companies and organizations. Former New York State Deputy Secretary for Public Safety Michael Balboni said that private entities "do not have the type of capability, bandwidth, interest or experience to develop a proactive cyber analysis."
In response to cyber-attacks on 1 April 2015, President Obama issued an Executive Order establishing the first-ever economic sanctions. The Executive Order will impact individuals and entities responsible for cyber-attacks that threaten the national security, foreign policy, economic health, or financial stability of the US. Specifically, the Executive Order authorizes the Treasury Department to freeze designees' assets.
According to Ted Koppel's book, in 2008, the United States in collaboration with Israel, ran a cyberattack on Iran's nuclear program, becoming "the first to use a digital weapon as an instrument of policy".
Consequence of a potential attack
A whole industry is working trying to minimize the likelihood and the consequence of an information attack.For a partial list see: :Category:Computer security software companies|Computer security software companies.
They offer different products and services, aimed at:
- study all possible attacks category
- publish books and articles about the subject
- discovering vulnerabilities
- evaluating the risks
- fixing vulnerabilities
- invent, design and deploy countermeasures
- set up contingency plan in order to be ready to respond
Computer emergency response teams are set up by government and large organization to handle computer security incidents.
Infrastructures as targets
Once a cyber-attack has been initiated, there are certain targets that need to be attacked to cripple the opponent. Certain infrastructures as targets have been highlighted as critical infrastructures in times of conflict that can severely cripple a nation. Control systems, energy resources, finance, telecommunications, transportation, and water facilities are seen as critical infrastructure targets during conflict. A new report on the industrial cybersecurity problems, produced by the British Columbia Institute of Technology, and the PA Consulting Group, using data from as far back as 1981, reportedly has found a 10-fold increase in the number of successful cyber-attacks on infrastructure Supervisory Control and Data Acquisition systems since 2000. Cyberattacks that have an adverse physical effect are known as cyber-physical attacks.Control systems
Control systems are responsible for activating and monitoring industrial or mechanical controls. Many devices are integrated with computer platforms to control valves and gates to certain physical infrastructures. Control systems are usually designed as remote telemetry devices that link to other physical devices through internet access or modems. Little security can be offered when dealing with these devices, enabling many hackers or cyberterrorists to seek out systematic vulnerabilities. Paul Blomgren, manager of sales engineering at cybersecurity firm explained how his people drove to a remote substation, saw a wireless network antenna and immediately plugged in their wireless LAN cards. They took out their laptops and connected to the system because it wasn't using passwords. "Within 10 minutes, they had mapped every piece of equipment in the facility," Blomgren said. "Within 15 minutes, they mapped every piece of equipment in the operational control network. Within 20 minutes, they were talking to the business network and had pulled off several business reports. They never even left the vehicle."Energy
Energy is seen as the second infrastructure that could be attacked. It is broken down into two categories, electricity and natural gas. Electricity also known as electric grids power cities, regions, and households; it powers machines and other mechanisms used in day-to-day life. Using US as an example, in a conflict cyberterrorists can access data through the Daily Report of System Status that shows power flows throughout the system and can pinpoint the busiest sections of the grid. By shutting those grids down, they can cause mass hysteria, backlog, and confusion; also being able to locate critical areas of operation to further attacks in a more direct method. Cyberterrorists can access instructions on how to connect to the Bonneville Power Administration which helps direct them on how to not fault the system in the process. This is a major advantage that can be utilized when cyber-attacks are being made because foreign attackers with no prior knowledge of the system can attack with the highest accuracy without drawbacks. Cyberattacks on natural gas installations go much the same way as it would with attacks on electrical grids. Cyberterrorists can shutdown these installations stopping the flow or they can even reroute gas flows to another section that can be occupied by one of their allies. There was a case in Russia with a gas supplier known as Gazprom, they lost control of their central switchboard which routes gas flow, after an inside operator and Trojan horse program bypassed security.Finance
Financial infrastructures could be hit hard by cyber-attacks as the financial system is linked by computer systems. Money is constantly being exchanged in these institutions and if cyberterrorists were to attack and if transactions were rerouted and large amounts of money stolen, financial industries would collapse and civilians would be without jobs and security. Operations would stall from region to region causing nationwide economic degradation. In the U.S. alone, the average daily volume of transactions hit $3 trillion and 99% of it is non-cash flow. To be able to disrupt that amount of money for one day or for a period of days can cause lasting damage making investors pull out of funding and erode public confidence.A cyberattack on a financial institution or transactions may be referred to as a cyberheist. These attacks may start with phishing that targets employees, using social engineering to coax information from them. They may allow attackers to hack into the network and put keyloggers on the accounting systems. In time, the cybercriminals are able to obtain password and keys information. An organization's bank accounts can then be accessed via the information they have stolen using the keyloggers. In May 2013, a gang carried out a US$40 million cyberheist from the Bank of Muscat.
