1.Denial of Service Attack:

A denial of service attack (DoS attack) generally consists of the concerted efforts of a person / persons to prevent an internet site or service from functioning efficiently. A DoS attack is an incident in which a user or organization is deprived of the services of a resource they would normally expect to have.

2.Distributed denial of service:

In a distributed denial-of-service (DDoS) attack, large numbers of compromised systems (sometimes called a Bot net) attack a single target, thereby causing denial of service for users of the targeted system. The flood of incoming messages to the target system essentially forces it to shut down, thereby, denying the service of the system to legitimate users.

3.Ransom ware:

Ransomware is a type of malicious software from crypto virology that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid.

4.Malware:

Malware is the term for maliciously crafted software code. Special computer programmes now exist that enable intruders to fool an individual into believing that traditional security is protecting him during online banking transactions. Attacks involving malware are a factor in online financial crime.

5.Phishing:

Phishing is the fraudulent attempt to obtain sensitive information such as usernames, passwords and credit card details, often for malicious reasons, by disguising as a trustworthy entity in an electronic communication.

6.Spear Phishing:

Phishing attempts directed at specific individuals or companies have been termed spear phishing. In contrast to bulk phishing, spear phishing attackers often gather and use personal information about their target to increase their probability of success. 

7.Whaling:

The term whaling has been coined for spear phishing attacks directed specifically at senior executives and other high profile targets. In these cases, the content will be crafted to target an upper manager and the person’s role in the company. The content of a whaling attack email may be an executive issue such as a subpoena or customer complaint. 

8.Vishing:

Vishing is the illegal access of data via voice over internet protocol (VoIP). Vishing is IP telephony’s version of phishing and uses voice messages to steal identities and financial resources. The term is a combination of ‘voice’ and ‘phishing’.

9.Drive-by-downloads:

Drive-by download means two things, each concerning the unintended download of computer software from the internet:

Downloads which a person has authorized but without understanding the consequences (e.g. downloads which install an unknown or counterfeit executable program, ActiveX component, or Java applet) automatically. 

Any download that happens without a person’s knowledge, often a computer virus, spyware, malware or crimeware.

10.Browser Gateway frauds:

11.Ghost administrator exploit:

A ghost administrator exploit is a code that takes advantage of a software vulnerability or security flaw to gain Administrator’s rights/privileges in the system. This exploit allows the attacker to mask his identity in order to remotely access a network and gain Administrator rights/privileges, or move deeper into the network. In some cases, an exploit can be used as part of a multi component attack, which can include backdoor viruses and/or spyware to steal user information from the infected systems.
