According to the Practical Law Company, Whitepaper on Cyber Attacks, the definition of Cyber Attacks is as follows:

A Cyber Attack is an attack initiated from a computer against a website, computer system or individual computer (collectively, a computer) that compromises the confidentiality, integrity or availability of the computer or information stored on it.

Backdoors – Backdoor is a type of cyber threat in which the attacker uses a back door to install a keylogging software, thereby allowing an illegal access to your system. This threat can turn out to be potentially serious as it allows for modification of the files, stealing information, installing unwanted software or even taking control of the entire computer.

Denial-of-Service Attack – A denial-of-service or a DOS attack generally means attacking the network to bring it down completely with useless traffic by affecting the host device which is connected to the internet. A DOS attack targets websites or services which are hosted on the servers of banks and credit card payment gateways.

Direct-access Attack – A direct-access attack simply means gaining physical access to the computer or its part and performing various functions or installing various types of devices to compromise security. The attacker can install software loaded with worms or download important data, using portable devices.

Eavesdropping – As the name suggests, eavesdropping means secretly listening to a conversation between the hosts on a network.

Spoofing – Spoofing is a cyber-attack where a person or a program impersonate another by creating false data in order to gain illegal access to a system. Such threats are commonly found in emails where the sender’s address is spoofed.

Tampering – Tampering is a web based attack where certain parameters in the URL are changed without the customer’s knowledge; and when the customer keys in that URL, it looks and appears exactly the same. Tampering is basically done by hackers and criminals to steal the identity and obtain illegal access to information.

Repudiation Attack – A repudiation attack occurs when the user denies the fact that he or she has performed a certain action or has initiated a transaction. A user can simply deny having knowledge of the transaction or communication and later claim that such transaction or communication never took place.

Information Disclosure– Information disclosure breach means that the information which is thought to be secured is released to unscrupulous elements who are not trustworthy.

Privilege Escalation Attack – A privilege escalation attack is a type of network intrusion which allows the user to have an elevated access to the network which was primarily not allowed. The attacker takes the advantage of the programming errors and permits an elevated access to the network.

Exploits – An exploit attack is basically a software designed to take advantage of a flaw in the system. The attacker plans to gain easy access to a computer system and gain control, allows privilege escalation or creates a DOS attack.

Social Engineering – An attack by a known or a malicious person is known as social engineering. They have knowledge about the programs used and the firewall security and thus it becomes easier to take advantage of trusted people and deceive them to gain passwords or other necessary information for a large social engineering attack.

Indirect attack – Indirect attack means an attack launched from a third party computer as it becomes more difficult to track the origin of the attack.

Computer crime – A crime undertaken with the use of a computer and a network is called as a computer crime.

Malware – Malware refers to malicious software that are being designed to damage or perform unwanted actions into the system. Malware is of many types like viruses, worms, Trojan horses, etc., which can cause havoc on a computer’s hard drive. They can either delete some files or a directory or simply gather data without the actual knowledge of the user.

Adware – Adware is a software that supports advertisements which renders ads to its author. It has advertisements embedded in the application. So when the program is running, it shows the advertisement. Basically, adware is similar to malware as it uses ads to inflict computers with deadly viruses.

Bots – Bots is a software application that runs automated tasks which are simple and repetitive in nature. Bots may or may not be malicious, but they are usually found to initiate a DoS attack or a click fraud while using the internet.

Ransomware – Ransomware is a type of cyber security threat which will restrict access to your computer system at first and will ask for a ransom in order for the restriction to be removed. This ransom is to be paid through online payment methods only which the user can be granted an access to their system.

Rootkits – A rootkit is a malicious software designed in such a way that hides certain process or programs from normal anti-virus scan detection and continues to enjoy a privilege access to your system. It is that software which runs and gets activated each time you boot your system and are difficult to detect and can install various files and processes in the system.

Spyware – Spyware, as the name suggests, is a software which typically spies and gathers information from the system through a user’s internet connection without the user’s knowledge. A spyware software is majorly a hidden component of a freeware program which can be downloaded from the internet.

Scareware – Scareware is a type of threat which acts as a genuine system message and guides you to download and purchase useless and potentially dangerous software. Such scareware pop-ups seem to be similar to any system messages, but actually aren’t. The main purpose of the scareware is to create anxiety among the users and use that anxiety to coax them to download irrelevant software’s.

Trojan Horses – Trojan Horses are a form of threat that are malicious or harmful codes hidden behind genuine programs or data which can allow complete access to the system and can cause damage to the system or data corruption or loss/theft of data. It acts as a backdoor and hence it is not easily detectable.

Virus – A computer virus is a self-replicating program which, when executed, replicates or even modifies by inserting copies of itself into another computer file and infects the affected areas once the virus succeeds in replicating. This virus can be harmful as it spreads like wildfire and can infect majority of the system in no time.

Worm – Just like a virus, worm is a self-replicating program which relies on computer network and performs malicious actions and spreads itself onto other computer networks. Worms primarily rely on security failures to access the infected system.

Phishing – Phishing is a cyber threat which makes an attempt to gain sensitive information like passwords, usernames and other details for malicious reasons. It is basically an email fraud where the perpetrator sends a legitimate looking email and attempts to gain personal information.

Identity Theft – Identity theft is a crime wherein your personal details are stolen and these details are used to commit a fraud. An identity theft is committed when a criminal impersonates individuals and use the information for some financial gain.

Intellectual Property Theft – Intellectual Property theft is a theft of copyrighted material where it violates the copyrights and the patents. It is a cybercrime to get hands onto some trade secrets and patented documents and research. It is basically a theft of an idea, plan and the methodology being used.

Password Attacks – Password attack is a form of a threat to your system security where attackers usually try ways to gain access to your system password. They either simply guess the password or use an automated program to find the correct password and gain an entry into the system.

Bluesnarfing – Bluesnarfing is a threat of information through unauthorized means. The hackers can gain access to the information and data on a Bluetooth enabled phone using the wireless technology of the Bluetooth without alerting the user of the phone.

Bluejacking – Bluejacking is simply sending of texts, images or sounds, to another Bluetooth enabled device and is a harmless way of marketing. However, there is a thin line between bluejacking and bluesnarfing and if crossed it results into an act of threat.

DDoS – DDoS basically means a Distributed Denial of Service. It is an attempt to make any online service temporarily unavailable by generating overwhelming traffic from multiple sources or suspend services of a host connected to the internet.

Keylogger – A keyloggers is a spyware that has the capability to spy on the happenings on the computer system. It has the capability to record every stroke on the keyboard, web sites visited and every information available on the system. This recorded log is then sent to a specified receiver.

MiTM (Man in the Middle): By impersonating the endpoints in an online information exchange (i.e. the connection from your smartphone to a website), the MITM can obtain information from the end user and the entity he or she is communicating with.

Malvertising: A way to compromise your computer with malicious code that is downloaded to your system when you click on an affected ad.

Watering Hole Attack: It is a computer attack strategy, in which the victim is a particular group (organization, industry, or region). In this attack, the attacker guesses or observes which websites the group often uses and infects one or more of them with malware. Eventually, some member of the targeted group gets infected.

Semantic attack: It is the use of incorrect information to damage the credibility of target resources or to cause direct or indirect harm. It is also the modification and dissemination of information to set someone into the wrong direction or to cover your tracks.

Ransomware: It is a type of malicious software designed to block access to a computer system until a sum of money is paid.
