Computer Hardware Ransomware Background

Remote code execution (RCE) seriously threatens your system and personal information. By executing arbitrary code on a remote device, a threat actor can steal sensitive data, disrupt system processes and use malware such as ransomwarespywareinfostealers and more.

By exploiting a security vulnerability on your device, attackers can access a machine remotely over public or private networks without the need to physically access it. It poses little risk for a hacker to perform an RCE, as it’s tricky for general users to track any malicious activity back to the attacker.

What exactly is it, and how can you defend yourself against it? This guide will explain what Remote Code Execution is and how to protect yourself using the best antivirus software.

What is Remote Code Execution (RCE)?

Remote code execution (RCE) is a type of cyberattack in which an attacker can execute code on a remote computer without physically accessing the computer. There are various types of attacks associated with RCE. Still, the most common trait is that they all exploit vulnerabilities on your device to run arbitrary code through remote servers or computers.

While RCE is part of vulnerabilities known as arbitrary code execution (ACE), which is a security flaw that allows threat actors to run commands on a target device, remote code execution is one of the more dangerous threats, as the attacker doesn’t any previous access to the target device.

Once a threat actor uses RCE on a system, it can lead to malware installation, stolen data, remote computer control, and operation disruption. The potential risk of damage is extremely high because of the various ways an attacker can use an RCE attack. This makes it a severe threat you’ll need to remove immediately.

Remote Code Execution by dangerous hacker on computers

What can Remote Code Execution be used for?

RCE is mainly used to wreak havoc on your system. Whether it be to steal data or use your computer’s resources, attackers take advantage of taking control of your device.

The purpose of RCE attacks include:

– Cryptomining: Running cryptomining malware will use your system’s resources to mine cryptocurrency, which can take a heavy toll on your computer. This makes the attacker a profit from using your device. Since it takes up a significant amount of processing power, your device will act slower, may crash often and will have little battery. It’s a good idea to check if you have high disk usage

– Ransomware: Attackers can deploy ransomware to deny users access to important files. It takes your data hostage by locking it up, with attackers often asking for payment for it to unlock again. 

– Denial of Service (DoS): Through an RCE attack, attackers can use code to restrict access to your system. It stops anyone from using the device by making it crash or overburdening its resources. 

– Steal data: By using infostealer malware or executing commands, attackers can exfiltrate information from your device. This can be login information and passwords, banking details, important documents or files, unencrypted data and more.

Examples of Remote Code Execution attacks

Because remote code execution can be categorised as various attacks, it can affect your computer in different ways. This includes:

– Injection attacks involve injecting malicious code into a vulnerable application. This can be done by exploiting vulnerabilities in SQL queries, web forms, or input fields.

– Cross-site scripting (XSS) attacks involve injecting malicious code into a web page. When a victim visits the web page, the malicious code is executed in their browser.

– Privilege escalation attacks allow attackers to gain higher access to a computer system. This can be done by exploiting vulnerabilities in operating systems, applications, or system configuration files.

This is why it’s essential to stay safe against all forms of cyber threats, especially those that exploit system vulnerabilities. Using a trustworthy antivirus can mitigate these attacks.

How to protect yourself from Remote Code Execution attacks

Fortunately, there are several ways to keep your system and information safe from RCE attacks. You can check out our guide on protecting yourself against remote code execution attacks on Windows.

However, the best way to defend against malicious attacks is by using the best antivirus software. If your system has a vulnerability, the proper antivirus will be able to identify malicious code trying to exploit a device’s weakness and get rid of it.

While not all antivirus software is equal, many high-standard AV protections offer near-perfect scores when detecting and protecting against malware, meaning even complex malicious software can’t go unnoticed.

Services, including Norton 360 (from $19.99/year) and Bitdefender (from $19.99/year), include device monitoring features to help uncover suspicious activity early and offer the tools to fight off cyberattacks. Whether it’s a phishing attack, ransomwarespyware or infostealer malware, these security products have the tools to protect you.

These services have protection features that block malicious activity on your device. To ensure your device is ready to identify and block malware damaging your system, set yourself up with an antivirus.
