What is an Exploit attack? How did it happen?

Exploit is a concept that describes network security attacks that exploit security vulnerabilities to penetrate and take control of any system. This attack often occurs in an operating system, an application, or any software code.

What is an Exploit attack?

Exploit is a concept used to describe network security attacks carried out by professional and highly qualified hackers. The goal of these attacks is usually to exploit security holes to gain control of any system or steal important data and assets.

This attack often occurs in an operating system, an application, or any software code. For the crypto market, hackers can attack and exploit many targets such as smart contracts, project websites, dApps,… to steal assets and cause damage to individuals and related organizations.

How does an Exploit attack in crypto work?

Attack the project

Large projects are the most common targets for this form of attack, especially in new projects or in new updates from already deployed projects. Because there exist errors during the process of the developer writing and deploying the product or application.

The above errors, although undesirable, have created vulnerabilities and brought potential risks to the system if discovered by hackers. And if discovered, these errors will quickly be exploited, thereby causing great damage to the project.

Attack users

Not only projects, but users in the crypto market are also targets that hackers aim to reach by using social engineering techniques. If unlucky users click on fake hacker links, it will immediately create conditions for hackers to get information and attack their devices or assets.

In addition, hackers can also spread malicious code to many devices in the same network to search for vulnerabilities. This is a form that does not require user interaction and just having a network connection in the same system is enough to make you a victim.

How many types of Exploit attacks are there?

Currently, exploit forms have developed diversely in the computer environment, and depending on the hacker’s purpose, some common forms include:

Local exploit

A form of attack that requires direct access to a vulnerable device within a certain range limit. By successfully exploiting the target system, the hacker can increase access beyond the normal permissions granted by the system administrator.

This form of attack has many limitations, from the scope of operation to intrusion operations, which mostly have to be done manually.

Remote exploit

This is a form of attack that operates in cyberspace to exploit remote security vulnerabilities without requiring prior or direct access to the target system. Therefore, the scope of operation of remote exploits is much wider than that of local exploits, and the target audience is also wider.

The danger of this form is that the program or software used will be pre-programmed to automatically attack when it successfully penetrates the device.

Client exploit

A form of attack that requires certain interaction with the user, which can be achieved through social engineering tricks. Accordingly, attackers can pretend to be employees or representatives of competent authorities to trick users into providing information to them.

The main methods used by hackers include phishing attacks, vishing attacks, and smishing attacks.

Zero-day exploit

Is a form of attack that targets an important security vulnerability that currently exists in an application or operating system. Hackers can find these vulnerabilities and exploit them before developers can recognize and fix them.

Developers may or may not be aware of this security vulnerability only to encounter hackers exploiting them.

Zero-click

A particularly dangerous form of attack was developed by NSO Group, a cyber intelligence company known for its proprietary spy software. Accordingly, Zero-click can penetrate and exploit vulnerabilities without requiring user interaction.

Because of the special and dangerous nature mentioned above, this form of attack was sold by NSO Group to the government.

Pivoting

It is a form used by hackers to increase their scope of influence, starting by infiltrating a part of the network infrastructure. From here hackers can move from the hijacked place to the remaining parts or related parties.

This is a very dangerous form of attack because if not prevented in time, it can cause the entire system to be controlled by hackers.

How to prevent Exploit attacks?

If you understand the dangers of an Exploit attack and want to prevent possible security breaches, here’s what you should do:

• Check and update security software regularly.
• Only use software from trusted vendors.
• Use 2-factor authentication methods.
• Control all your online activities, and avoid accessing strange links.
• Organize Bug Bounty Programs if you are participating in a large project.
