In today’s increasingly digital world, the internet has become a necessity for business and personal life. From communication to commerce, the internet has become a part of our lives. However, the internet is not perfect, and there are many vulnerabilities that allow for hackers to attack your system and steal your data. One such vulnerability is remote code execution (RCE).
Capable of taking control of your computer without your knowledge, RCE vulnerabilities allow hackers to install malware, steal data, and access your system without your permission. But how do you know if you have an RCE vulnerability? Or, if you do, what should you do about it?
To help you in your endeavor to protect your system, we have created a guide that will walk you through the different types of RCE vulnerabilities and how they work, as well as some tips on how to protect yourself from them. So, without any further ado, let’s get started!
What is Remote Code Execution?
So, what is remote code execution?
Remote code execution (RCE) is a vulnerability in software that allows an attacker to take control of a device without ever having to physically access it. RCE vulnerabilities are often found in common web applications and services, like WordPress, Drupal or Joomla.
Because the attacker doesn’t need to access the device in order to exploit the vulnerability, it can be used to target large numbers of users at once. An attacker could use RCE vulnerabilities to install malware on your device that steals your information, including passwords and credit card numbers. It could also be used to turn your device into a botnet—a group of devices controlled by an attacker—which can be used for distributed denial of service attacks (DDoS).
The best way to prevent RCE is by keeping your software up to date. Most operating systems and applications come with automatic update features, so make sure yours is turned on. If you’re running an older version of a piece of software, or if the update process isn’t working properly, manually check for updates using your computer’s built-in application updater tool.
What Kind of Attacks Can We Expect with This Vulnerability?
The remote code execution vulnerability is a big one, and it’s important to understand what kinds of attacks we can expect with this vulnerability.
There are a few different types of attacks that are possible with this vulnerability. First, there’s a remote code execution attack that happens when you visit a website that has been compromised by an attacker. The attacker can then run malicious code on your computer and take control of it.
Another kind of attack is known as an unsolicited message attack, where an attacker sends you an email or instant message containing malicious code that will be executed on your system when you open the message or file. This type of attack is typically used to gain access to sensitive data or install malware on victims’ computers.
Thirdly, if attackers want to do something destructive or disruptive, they could easily use this vulnerability to run malicious software on any number of machines at once and cause widespread damage in just minutes. But even if they don’t have malicious intentions, they could still use remote code execution vulnerabilities to steal sensitive data from multiple systems without having physical access to any of them at all!
Finally, there is also a local privilege escalation vulnerability in Windows 10 versions 1809 through 1903 that could allow attackers to take over local accounts on affected systems using only user privileges. This is a serious vulnerability, because it means that attackers wouldn’t need to have administrator privileges in order to take over local accounts on affected machines. They could simply use a malicious program or script that runs with user privileges and then use it to elevate their own permissions and take control over the system.
How Do We Secure Our Systems from Remote Code Execution Vulnerability?
As a concerned business owner, what can you do to protect your systems from Remote Code Execution Vulnerability? Well, there are some steps that you can take right away to help secure your systems.
1) Never Run Applications as Admin Unless You Really Need To
One of the biggest ways that we can protect our systems from remote code execution vulnerability is to avoid running applications as administrator. If you’re running a compromised application as admin, a hacker can easily take control of your system. This is why you should only run applications as admin when you really need to. Even then, it’s better if you can avoid it altogether by using Group Policy or other similar tools.
If you do need to run an application as admin, make sure that there are no unnecessary services running on your machine. This will reduce the chances of something going wrong if someone manages to gain access to your system through these services.
2) Keep Your Operating System up to Date
It’s likely that you’ve heard this before, but we’re going to say it again: keeping your operating system up to date is one of the best ways to avoid remote code execution vulnerabilities. This means updating regularly and ensuring that you have the latest patches installed.
If your system has been compromised, updating it will often fix the issue. If not, then at least you’ll be running on a patched version of the software, which increases security.
You should also consider disabling scripts in your browser and making sure that all plugins are up to date. If you suspect that your system has been compromised, consider using an antivirus product or performing a scan with a malware removal tool like Malwarebytes’ Anti-Malware for Mac or Windows.
3) Treat All Unknown Files with Suspicion
When it comes to protecting your systems from remote code execution vulnerabilities, you can’t be too careful.
We know that sounds like a lot of work and maybe even a little paranoid, but it’s absolutely worth it—if you want to be able to sleep at night!
The easiest way to secure your systems is by treating all unknown files with suspicion. If you’re new to this kind of thing, it might seem like an overwhelming task, but we’ve got your back. Here are a few tips for making sure your system is as safe as possible:
- Always check the file extension before opening or downloading any file from an untrusted source. If it doesn’t have the .exe extension, don’t open it!
- Run anti-malware software regularly so that any unrecognized files can be identified as malicious and blocked from accessing your computer or network.
- Set up firewall rules so that external connections are blocked unless you explicitly allow them through the firewall using a set of rules that only allows trusted connections to enter your computer or network.
Remote code execution is a very serious issue, and it needs to be addressed as soon as possible. If you’re not sure how to protect yourself from this type of attack, contact us today! We’ll help you ensure that your computer and network are safe from malicious attacks.
