Losing Important Data

Data theft is the most common occurrence of cybercrime. The main purpose of data theft is generally related to finance for the benefit of the hacker. This of course will be very detrimental to the victims because they lose important data and privacy.

Damage to Computer Software and Devices

Theft of important data is not the only reason why cybercrime is a very dangerous act. Cybercrime can also cause damage to software or computer equipment.

Damage that occurs to the software or computer will certainly provide a very large loss. Damage that occurs to the device can have a wide and varied impact. Especially if the computer device uses a pirated or outdated operating system.

Commonly Used Cyber ​​Crime Methods

cybercrime methods

Hackers generally have several different methods to carry out cybercrimes. For information, the following are the methods commonly used in cybercrime:

Spoofing Method

A relatively common method used in cybercrime is spoofing. In short, spoofing is the act of falsifying identity or data so that the perpetrators can enter a certain network or even into the account of the original owner.

After hackers manage to get into the network or server, then they can carry out criminal acts according to their goals. Starting from data theft, financial theft, and can even destroy the system.


The next method that can also be used to commit cybercrime is Sniffing. The sniffing method is an attempt to steal someone else’s account which includes passwords and usernames. So that the account is actually taken over by people who should not.

After the account is taken over, the hacker can do many things for his personal gain. Of course, this action will have a negative impact on victims who experience account theft.

Destructive Device

A destructive device is a particular software or program that contains viruses, such as nukes, trojan horses, worms, and email bombs. This is usually intended to damage or destroy data on the computer concerned.

Password Cracker

The next method that is often used in cybercrime is a password cracker. This method is an attempt to steal someone’s account password with the help of a certain program to be able to open the password encryption.


DDoS or Distributed Denial of Attacks is an attack on a computer or server in the internet network that can consume a lot of resources so that the network cannot function properly.

Examples of Cyber ​​Crime Cases

types of cyber crime cases

Generally, there are many types of cybercrime cases that occur in this world. Some examples of common cybercrimes are as follows:


One of the cases of cybercrime is phishing. It can be said that phishing is the most common cybercrime case by hackers.

Phishing is done with the aim of stealing the victim’s important data, such as username, password, identity, PIN, and so on. This crime is usually carried out by tricking the victim through fake sites, fake links, and so on.


An example of a cybercrime case that is no less popular is Hacking. The perpetrators of this crime are called hackers. Hackers can attack any network or server they want for a specific purpose.

In short, hacking is a cybercrime that breaks into other parties’ computer networks with various purposes, such as stealing data, damaging systems, and others. Hacking is a crime that is relatively common, especially on the internet.

Malware Attack

Malware attacks are an example of cybercrime that also needs to be watched out for. Malware attacks are carried out by infiltrating software on the victim’s computer that comes from various media, ranging from fake websites, emails, or website themes.

Social Engineering

Social Engineering is also an example of cybercrime that has recently been rampant. These cybercrimes generally target digital banking users or people who often carry out internet banking activities.

Generally, the perpetrators manipulate the victims by directly contacting them. Some of them asked about OTP (One Time Password) and so on with the aim of being able to get financial benefits from user carelessness.

To avoid any loss, it is highly recommended not to give any OTP code to other people. Because OTP is unique and personal with the aim of security authentication when logging into certain networks.

Exploit Kit

Exploit kit is a computer attack program that has a low security system. By exploiting loopholes due to low security, this program can download malware so that the computer can be controlled by perpetrators freely.

Using Two Factor Authentication

The next way to avoid cybercrime is to use two-factor authentication. This method is relatively powerful enough to protect accounts from the risk of data theft or cybercrime.

In short, Two factor authentication or 2FA is a double security method by verifying in real time. So not only username and password, you will also be asked to enter the OTP code via SMS or email.

Using SSL

SSL is one of the additional security of the website and you can usually find it on the URL of a website. The SSL display uses a padlock icon display next to the URL. The existence of this SSL guarantees that every internet data exchanged between visitors and the website is protected through encryption techniques.
