Cybercrime for dummies

"Botnets are networks of virus-infected computers controlled remotely by an attacker. The Coreflood virus is a key-logging program that allows cyber thieves to steal personal and financial information by recording unsuspecting users’ every keystroke" 

Cybercrime is a war zone. But instead of A47's dropping missiles, hackers are shooting emails and links fully armored to take out the computers intelligence system and reprogram. Information is valuable to the infrastructure of every organization. The United States is held together by public works (exp.: oil, water, gas, & electric) known as critical infrastructure. Hackers have the ability to penetrate the systems that make these technologies tick. The public should equate a bomb threat to a cyber attack; if a hacker reprograms a pipeline, it will blow, just like if a bomb went off. Because a cyber attack has the capability to do the same damage to the physical and economic infrastructure. Cybercrime is detrimental to the economy because it causes billions of dollars in damage each year, it effects a large amount of people, and it has the ability manipulate our critical infrastructure, which without could put the whole country in physical and economical turmoil.



DEFINITIONS

Computer attack: A generic term for a malicious action whose target and means involves  computing.

Botnet: Network of malicious robots ("bots"), installed on compromised machines ("zombies"), in a number to ensure active camouflage and to direct its actions to one or more determined targets (ex. Distributed denial of service (DDoS) or mass emails ("spam")).

"Botnet" controller ("bot herder"): Individual responsible for remotely managing and monitoring a network of robots through a C&C Control and Communication server.

Trojan horse: Hidden malicious code that can take control of the compromised computer without the knowledge of the legitimate user.

Cloud computing: Method of processing client data, using the Internet, in the form of services provided by a service provider. This is done using a cloud computing model that provides access to a shared set of configurable resources over an on-demand network. Its resources include networks, servers, storage, applications, and other elements, arranged into "clouds" in various geographical locations, without the specific location or operation of the cloud being made known to clients.

Malicious code ("malware"): A program developed for the purpose of causing harm through a computer system or a network. Trojan horses, viruses, and worms are forms of malware, characterized by the presence of propagation, triggering, and action mechanisms that are often developed with an intent to cause harm.

Cyberattack: A malicious act through a computing device, generally over a telecommunications network.

Cyberthreat: A local or remote threatening action targeting information or information systems.

Denial of Service (DoS): An action to prevent or greatly limit the ability of a system to provide an expected service.

Distributed Denial of Service (DDoS): An action launched from multiple sources, especially by means of a botnet.

Phishing: Misleading technique intended to obtain personal information by misleading the holders of that information.

Fraud: A deliberate illegal act carried out by one or more subtle means, with the intention to deceive in order to gain an advantage. This can take various forms, which may or may not require complicity, leading to injury to the victim.

Social engineering: A method of obtaining an asset or information by exploiting trust, ignorance, or credulity, or by applying psychological pressure or appealing to one’s compassion.

Accountability: Security property associated with monitoring performed operations and functions, without possible repudiation.

Integrity: Security property associated with storing data and components without corruption in space and time.

Intrusion: Introduction and maintenance of a fraudulent character in a system for the purpose of retrieving or modifying, or else altering or destroying.

Pirated machine or "zombie": A machine compromised by a malicious robot ("bot") on a network ("botnet") directed by a "bot herder".

Hacker: An individual who breaks into a computer system for an intellectual challenge, with malicious intent, or for profit, acting alone or as part of a group.

Spam: Unsolicited email messages, often sent in large numbers.

Address spoofing: The act of deliberately replacing one address with another address, such as a physical MAC (Medium Access Control) address, IP address, domain address, email address, etc.

Identity Theft: Temporary or permanent borrowing of a person’s identity by appropriating the victim’s identifiers.

CNBC— Code Wars: America's Cyber Threat

On August 14, 2003 there were massive power blackout in Northeast, most prominently affecting New York and Toronto. One hundred power plants shut off, phone lines and water lines were down and people were trapped in elevators. Just a few days before in Toronto and computer virus known as blaster had infected airline and train technology, delaying their departure for many hours. The officials claimed that blaster was not the official cause of the largest blackout in American history that totaled no less than 60 billion dollars of damage. The official cause was overgrown trees and brush on power lines. However, virus hunter Mikko Hypponen disagrees. According to the report, the screens flashed black screens and described everything that would be the cause of blaster. As blaster is a worm, it doesn't need programs to propel itself on the net. Your computer could get a worm by being online, like the financial network, power plants, water treatment centers and nuclear reactors. As most people disagreed with the official report it was a wake-up call: computer viruses could impact the physical world.


Example of how a blaster worm works.

Operation Ghost Click



          On the ninth of November in 2011 six Estonian nationals were arrested for infecting over a million computers worldwide in a cyber fraud ring to puppeteer the "MUTI-BILLION-DOLLAR Internet advertising industry." This virus made compromised users at risk for other malicious viruses. This fraud ring began in 2007 with a malware called DNSCharger that infected 4 million business, personal and governmental agency computers, 500,000 in the United States. The virus was able to scam 14 million dollars, and often damaged users' ability to update their anti-virus.
What is a DNSCharger?
A DNS (Domain Name System) is the thing that converts the domain name into numerical numbers, which is what allows computers to communicate with each other like emailing and surfing the web. So what the DNSCharger did was give the hackers control over the users web activity. So when a user clicked on a link they were taken to a different website. The thieves would sometimes create a duplicate of a legit website and sell their products; however when customers would purchase off the fake website the cyber criminals would steal their money, gain access to their computer, and deprive the actual websites of traffic. 
Because of rare international cooperation between the FBI and Estonian officials the six responsible for the cybercrime are in custody and will be extradited to the United States.
