The Hidden Risks of Remote Access Tools: What Small Businesses Need to Know
Remote Access Tools, also known as Remote Administration Tools, are software programs that allow someone to access and control a device from a different location. These tools are commonly used to provide remote technical support or to let someone access their computer, or even a server, from home.
Microsoft includes a built-in tool called RDP (Remote Desktop Protocol), and there are many third-party applications such as VNC, TeamViewer, and AnyDesk that offer similar functionality across both Windows and non-Windows devices.
While these tools offer convenience, they can also open the door for cybercriminals. One of the biggest risks is that remote access tools are sometimes installed on devices without the user’s knowledge. Even when installed intentionally, they can be exploited by attackers.
The Risks of Remote Access Tools
If you can access your device remotely, there's a good chance an attacker can too, especially if they find a vulnerability in the software. And they often do. All software has flaws from time to time, and while developers work to fix them, there's always a gap between discovery and patching. That gap is the attacker’s window of opportunity.
Another major threat is how these tools are used in malware attacks. If your device is compromised, an attacker may install a remote access tool to gain long-term control. This type of malware is called a Remote Access Trojan (RAT).
In cybersecurity, we call this persistent access, meaning the attacker can return at any time to continue or expand their attack. Once they’re in, they can reach anything your device is connected to: other computers, servers, cloud storage, even bank accounts.
One of the most devious tactics involves social engineering. Attackers trick people into installing remote access tools themselves. A common scam starts with a pop-up warning that your device has been compromised, urging you to call a support number. On the other end of the line is the attacker, pretending to be a helpful technician. They walk you through installing a remote access tool, effectively handing over control of your device. This scam is all too common and unfortunately, very effective.
For small businesses, these tools are often abused in ransomware attacks. Once an attacker gains access, they may install additional malware to disable antivirus software and other security protections. From there, they can encrypt or steal sensitive data, threatening to publish it unless a ransom is paid.
A particularly dangerous aspect is when a remote access tool is already installed. Attackers don’t need to deploy their own, they just exploit what’s already there, either through a known vulnerability or by misusing existing access.
How to Use Remote Access Tools Safely
Here are some simple but critical steps to reduce your risk:
Avoid using remote access tools unless absolutely necessary. If you don’t need one, check your system to make sure none are installed.
Never install software at the request of someone you don’t know. Legitimate support personnel will never pressure you to install remote access tools unexpectedly.
Only enable remote access when you need it. It’s tempting to leave it on for convenience, but that increases your risk.
Secure the tool’s settings. Review and tighten the configuration options and limit who can access it, when, and how.
Require multi-factor authentication (MFA). If your tool doesn’t support MFA, consider switching to one that does.
Use limited-access user accounts. Don’t log in with full administrator rights unless absolutely necessary. The more rights an attacker has, the more damage they can do.
Final Thoughts
Good security comes down to awareness and discipline. Always be alert to social engineering attempts, and take the time to configure tools properly before using them. Remote access tools can be used safely, but only if you secure them. Failing to do so puts you and your business at significant risk.
