Cryptojacking and how to protect your devices

Audience: mid-level IT professionals.

INTRO:

Cryptojacking is a malicious attack that uses a computer’s processing power to mine cryptocurrency without the user’s knowledge or permission. It is a form of cyber crime that has been gaining in popularity, as it can be done without traditional malware. Knowing what cryptojacking is and how it works, as well as understanding the potential risks and implementing security solutions, is essential in order to protect your devices from this type of attack.

What is Cryptojacking?

Cryptojacking is a type of cyber attack in which malicious actors use a computer’s processing power to mine cryptocurrency without the user’s knowledge or permission. This type of attack is becoming increasingly popular, as it does not require malware and can be done in a much more subtle way than traditional malware attacks.

How Does Cryptojacking Work?

Cryptojacking works by exploiting a computer’s processing power to mine cryptocurrency. The malicious actors will either install a piece of software on the computer that mines cryptocurrency or insert code into a website or web page that will begin mining cryptocurrency when the user visits the page. This code can be inserted into a website via an advertisement or via malicious JavaScript code.

Why is Cryptojacking Popular?

Cryptojacking is popular because it is relatively easy to do and can be done without traditional malware. Additionally, it is a low-risk attack, as the malicious actors do not have to worry about the victim discovering the attack and taking action to stop it.

How to Identify Cryptojacking

Cryptojacking can be difficult to identify, as the malicious actors are not installing any malicious software. However, there are some signs that a computer may be the victim of a cryptojacking attack, such as slow processing speeds, random crashes, and an increase in electricity usage.

Potential Risks of Cryptojacking

Cryptojacking can have a number of serious consequences, including financial losses, data breaches, and even physical damage to the computer. Additionally, cryptojacking can be used to launch other malicious attacks, such as ransomware, or to mask other malicious activities.

Mitigating Cryptojacking Risks

In order to mitigate the risks associated with cryptojacking, it is important to take a layered approach to security. This should include patching operating systems, limiting administrative rights, evaluating network connections, securing web browsers, educating employees and clients, and monitoring for suspicious activity.

Security Solutions for Cryptojacking

Patching Operating Systems: It is important to keep your operating system up-to-date in order to protect against potential vulnerabilities that could be exploited by malicious actors. This includes regularly updating your operating system and any security patches that are available.

Limiting Administrative Rights: Limiting the administrative rights of users on your network can help to reduce the risk of cryptojacking, as it limits the ability of malicious actors to install malicious software or code.

Evaluating Network Connections: It is important to evaluate who is connecting to your network, as malicious actors may attempt to connect to your network in order to gain access to your computers.

Securing Web Browsers: It is important to secure your web browsers, as malicious actors may attempt to use malicious code or advertisements to gain access to your computer. This can be done by using a secure browser such as Google Chrome or Mozilla Firefox.

Educating Employees and Clients: Educating employees and clients about the risks of cryptojacking is essential in order to help them protect their computers from this type of attack.

Monitoring for Suspicious Activity: It is important to monitor for any suspicious activity on your network, as this can be an indication of a potential cryptojacking attack.
