Today, the internet plays an important role in our life whether personal, financial, or even in business. Because of its massive usage, the number of cyber hackers has also risen to unprecedented heights where they are just waiting for unsuspecting individuals to lower their security and become a victim of their illegal activity. In order to protect your data or your business for that matter, it is important to understand the personalities behind this dangerous and unlawful crime.
What is cybercrime?
Cybercrime is any illegal activity that involves a computer or other computing devices, as well as mobile phones. Cybercrime is not only carried out for profit by cybercriminals, but it’s also done by cyberhackers to damage and disable computer networks for malicious intent.
The three types of cybercrime can be defined as:
- Crime to gain access to computer networks.
- Crime using computing devices like a weapon, such as DDoS attacks (Distributed Denial of Service).
- A crime where computers are used for the storage of stolen data.
Cybercrime is one of the biggest threats to businesses and organizations and includes a wide range of illegal and malicious activity that can compromise the security and integrity of data.
Different Types of Hacking techniques
Cyberhackers use a variety of ways to get into computer networks. Here are the most common techniques used by hackers to obtain your data illegally:
Malware is a type of malicious software that’s downloaded and installed on computer systems without permission or knowledge. The software contains code inserted by cyber hackers so they can gain illegal access to networks and computing devices. The destructive code can be embedded within an email, website links, or software that’s being downloaded. Once the code is executed, it copies itself and links to other applications on the computer, making the entire system a vulnerable target.
There are different types of malware, such as spyware, which gathers confidential information including financial data, credit card details, and personal information. Another form of malware is Trojans, which are disguised as legitimate applications and software. When executed on computers, trojans open up a back door, allowing other types of malware to enter.
Phishing happens when users receive an email that looks as though it’s legitimate. Cyberhackers typically attempt to imitate a well-known organization that’s easily identified, such as financial institutions. Hackers count on unsuspecting users to open and read the email and then enter their banking and personal information. Businesses need to have strict policies in place for phishing emails, training employees to never provide information in an email without first contacting IT.
DDoS – Distributed Denial of Service
Cyberhackers perform DDoS attacks to damage computer systems with the intent of shutting down the entire network, including computers and mobile phones. The goal is to overwhelm networks with so much traffic that they become inoperable. The main motivations behind DDoS are for revenge, for political activism, and for blackmail, where cyber hackers demand payment for return to service.
An SQL injection attack is often used to target low-security websites. Cyberhackers insert SQL statements into the text fields on a website that capture information, such as usernames and passwords. The SQL code can be used to either get information from the website or attack visitors to the site. Inserted code can also allow the hacker to get a foot in the door for future attacks.
As time goes by, cyber hackers are continuing to find ways to attack any individuals anytime. This is the reason why knowing how these criminals attack is a good start in increasing your protection from cybercrimes and attacks.
