Updated on 03rd Jul, 21 61 Views

Any criminal activity carried out over the internet is referred to as Cyber Crime. With 4.5 million attacks in July 2020, India was the country with the highest number of attacks, making it vital to raise awareness about cybercrime. To steal data or information, criminals use a computer and the internet.

In 1973, the first example of cybercrime was documented. A computer was used by a teller at a local New York bank to pilfer over 2 million dollars. In the year 1978, the first email spam was sent.

In this blog, we will learn about Cyber Crime in general and several risks and prevention strategies. Let’s take a look at what is going to be covered in this blog:

What is the Definition of Cyber Crime?

Let’s start with a definition of “what is Cyber Crime? Cyber Crime refers to any criminal conduct committed with the aid of a computer or other electronic equipment connected to the internet. Individuals or small groups of people with little technical knowledge and highly organized worldwide criminal groups with relatively talented developers and specialists can engage in Cyber Crime.

Cybercriminals or hackers who want to generate money commit the majority of Cyber Crime, but not all. Individuals and organizations are both involved in Cyber Crime. Aside from that, cybercriminals might utilize computers or networks to send viruses, malware, pornographic materials, and other unlawful data.

To make money, cybercriminals engage in a range of profit-driven criminal acts, including stealing and reselling identities, gaining access to financial accounts, and fraudulently utilizing credit cards to obtain funds. 

Examples of basic Cyber Crime

  1. Stolen credit card information: The most common Cyber Crime occurs when a person’s credit card information is stolen and used unlawfully to acquire or purchase goods or services over the internet.
  2. Hacking into a government website: Another type of Cyber Crime is tampering with sensitive government data.

Cyber Crime Categories

Cyber Crime has broadly categorized into 3 fields:

  1. Individual: Cyber Crime entails a single person disseminating malicious or unlawful material via the internet. This category involves a single person disseminating bad material over the internet. Distributing pornography, human trafficking, and online stalking are all examples.
  2. Property: A person’s bank or credit card information. To obtain access to funds, make online transactions, or execute phishing schemes to persuade individuals to give away their information, criminals use people’s bank details.
  3. Government: While these sorts of Cyber crimes are uncommon, they are nevertheless considered significant offenses. It entails breaking into government databases and hacking official websites. Terrorists are the hackers who break into government websites.

What Are the Different Types of Cyber Crime?

There are several types of Cyber Crimes, the most common ones are email frauds, social media frauds, banking frauds, Ransomware attacks, Cyber Espionage, Identity theft, clickjacking, Spyware, etc. Let us now see how these crimes are executed. 

1. Malware

Malware is a broad phrase that encompasses a wide range of cyberattacks such as Trojans, viruses, and worms. Malware is simply described as code written to steal data or destroy things on a computer.

How malware causes harm can assist us to classify the type of virus we’re dealing with. So let’s talk about it!!

  • Viruses: Viruses, like their biological namesakes, attach themselves to clean files and infect other clean files, and they can spread uncontrollably, causing damage to the core functionality as well as deleting and corrupting files. They usually appear as executable files that the user downloaded from the internet.
  • Trojan: This type of malware masquerades as legitimate software that can be hacked. It prefers to function invisibly and creates security backdoors that allow other viruses to enter the system.
  • Worms: Worms use the network’s interface to infect a whole network of devices, either locally or via the internet. It infects more machines with each successive infected machine.

2. Phishing

Phishing frequently poses as a request for information from a reputable third party. Phishing emails are sent to consumers and invite them to click on a link and enter their personal information.

In recent years, phishing emails have become much more complex, making it impossible for some people to distinguish between a real request for information and a fraudulent one. Phishing emails are sometimes lumped in with spam, but they are far more dangerous than a simple advertisement.

There are five steps to phishing:

  • Preparation: The phisher must pick which business to target and how to obtain email addresses for that business’s customers.
  • Setup: Once they’ve decided which firm to mimic and who their victims will be, they’ll begin the setup process. Phishers construct communications to distribute them and collect data.
  • Carry out the attack: This is a process that most people are familiar with. The phisher sends a fake message that appears to come from a well-known source.
  • Recording data: The phisher keeps track of the information that victims submit to websites or pop-up windows.
  • Identity theft and fraud: Phishers use the information they collect to make unlawful transactions or perform other forms of fraud, and up to a quarter of the victims never fully recover.

3. DDos: Distributed denial of service

As the name implies, a Dos attack focuses on disrupting network service. Attackers transmit a large amount of data traffic via the network until it becomes overloaded and stops working. Dos attacks can be carried out in a variety of methods, but the most common is a distributed denial-of-service attack. This involves the attacker sending traffic or data that will overload the system utilizing several machines.

A person may not recognize that his or her computer has been hijacked and is helping to the Dos attack in many cases. Disrupting services can have major ramifications for security and Internet access; many large-scale dos attacks have occurred in the past. Many instances of large-scale DOS attacks have been implemented as a single sign of protests towards governments.

4. Man in the Middle Attack

The man-in-the-middle attack can obtain information from the end-user and the entity with which he or she is communicating by impersonating the endpoints in online information exchange.

Let’s look at an example to learn more about the attack.

If the user is banging online, the man in the middle would communicate with the user by impersonating the bank. The man in the middle would receive all information transferred between both parties, including sensitive data such as bank accounts’ personal information.

5. Drive-By Download Attacks

To become infected, we no longer need to click to accept a download or install a software update. Simply opening a compromised webpage may now allow dangerous code to be installed on the device. We only need to visit or drive by a website by clicking accept for any software, and the malicious code will be downloaded in the background to your device.

The unintentional download of a virus or malicious software onto a computer or mobile device is referred to as a download from these pages.

Drive-by downloads typically take advantage of or exploit an out-of-date browser, app, or operating system with security flaws.

Tips for Preventing Cyber Crime

  • Backup all data, the system, and any considerations: It enables data to be stored earlier to assist the business in recovering from an unplanned event.
  • Enforce concrete security and keep it up to date: Choose a firewall with features that protect against malicious hackers, malware, and viruses. This enables us to identify and respond to threats more quickly.  
  • Never give out personal information to a stranger: They can use the information to commit fraud on others.
  • Check the security settings to prevent cybercrime: A cyber firewall checks your network settings to see if anyone has logged into your computer.
  • Using Anti-virus Softwares: Using anti-virus software will help you recognize any threat or malware before they infect your computer system. Never use cracked software as they are cracked by hackers and may impose the serious risk of data loss or malware attack.
  • When visiting unauthorized websites, keep your information secure: Using phishing websites, information can easily bypass the data.
  • Use virtual private networks: VPN enables us to hide our IP address and delete your website’s activities.
  • Restriction on access to your most valuable data: Make a folder if possible so that no one can see the confidential document.
