Different types of Cybercrime
Nowadays, all digital devices such as computers, notebook, and smartphones are connected to the internet. So, there has a chance to attack by cybercriminals. There are different types of cybercrime and here we have discussed some common forms of cybercrime which are as follows:
A Hacker is a person who alters the system or security features, finds weakness and exploits the vulnerability in computer systems or network to gain access and accomplish a goal.
Hacking is a process that identifying the weakness in computer systems or networks and control over computer security system in order to gain profit or unauthorized access for illegal purpose.
A Denial-of-Service or DoS attack is a type of cybercrime which shut down a system or network and making it inaccessible to the intended users.
In this attack, an attacker attempt to prevent legitimate users from accessing specific computer systems, devices or other resources.
In addition, DoS attack typically flooding a targeted system with requests until normal traffic is unable to be processed, resulting in denial-of-service to users.
Zero day attack is the application based computer security threats which is unknown security vulnerability or security hole in a software or application.
It is happen when the security patch has not been released or the application developers were unaware of or did not have sufficient time to fix the vulnerability.
However, if the vulnerability is not solved by the developer then it can effect on computer programs, data, or a network.
7. SQL Injection
SQL injection is one of the most common types of cybercrime that allows attacker to control an application’s database. In many cases, an attacker can modify or delete this data including the malicious code in SQL statements, via web page input.
These types of attack occur when an application fails to properly sanitize the SQL statements then attacker can include their own malicious SQL commands to access the database.
8. Cross Site Scripting (XSS)
Cross-site Scripting (XSS) is a web security vulnerability and client-side code injection attack, in which execute malicious scripts in a web browser of the victim by including malicious code in a legitimate web page or web application.
It occurs when a victim visits that type of web page or web application that executes the malicious code inside the victim’s browser then the attacker can fully compromise their interaction with the application.
Spoofing is a type of threat where an attacker attempts to gain unauthorized access to a user’s system or information by pretending to be the user.
In general, spoofing is a fraudulent attempt in which communication is sent from an unknown source and disguised as a known source to the receiver.
Its main purpose is to spread malware, stealing user’s sensitive information such as bank account details, personal information, login credentials, credit card details etc.
Types of Spoofing
The most common forms of spoofing are IP Spoofing, email spoofing, and DNS spoofing and email spoofing is one of the best known spoofing.
10. Social Engineering
Social engineering is a type of cyber-attack in which cyber criminals make a direct contact with victim through phone calls, emails or victim clicking a deceptive link or visiting a malicious website.
It is a popular tactic of cyber-attack because it is often easier to exploit user’s weaknesses and vulnerabilities such as their emotions, easy mindless than it is to find a network or software vulnerability.
Types of social engineering attacks
The most popular types of social engineering attacks are phishing, spear phishing, bating etc.
Ransomware is a type of malicious software or program that blocks to access computer system and demands for bitcoin in order to access the system.
The most dangerous ransomware attacks are WannaCry, Petya, Cerber, Locky and CryptoLocker etc.
Above all types of attack typically installed in a computer system through the following ways:
When download and open a malicious email attachment
Install an infected software or apps
User visit a malicious website or link
Click on untrusted web link or images
Cybersquatting is a criminal offense related to website domains which registering, selling or using a domain name with bad-faith intent to profit. It is also known as domain squatting.

And if the address is inaccessible or states the following message then you are victim of cybersquatting.
The website is “under construction”
Browser displays “cannot find server” error
Information about how to buy this domain
The website has no relation to the domain name
Cyberstalking is technological harassment in which the attacker harasses a victim using electronic communication, such as e-mail or messages posted to a Web site or a discussion forum, Social media, blog.
