In recent years, data breaches have become increasingly alarming. Just last year alone, over 1 billion records were stolen by hackers — a truly staggering number. What’s even more concerning is that remote control attacks on computers are now more frequent than ever.

According to a study by Check Point Research, between August 2024 and January 2025, the top three targets for cyberattacks in Taiwan were hardware suppliers, government and military agencies, and the manufacturing industry. Whether you’re an individual user or a business, it’s time to take computer security seriously.

If your computer has been acting strangely — for example, your mouse moves on its own, files are mysteriously modified, or the system suddenly slows down — that could be a sign of a hacker intrusion. Sometimes, a remote desktop program you used before may still be secretly running in the background. Once your system is under malicious remote control, not only can your personal data be stolen, but your computer might also be used as a tool to attack others.

This article provides a full guide on how to detect, block, and prevent such threats — helping you regain control of your computer.

How to Detect If Your Computer Is Being Remotely Controlled

If you suspect that your computer is being accessed remotely, the first step is to learn how to detect it. Fortunately, you can use built-in system tools and commands to quickly check if someone is secretly accessing your device.

Detect Remote Control on Windows

Windows provides several built-in tools for system inspection. The following three methods can help you identify unusual remote connections quickly.

Method 1: Check Logged-In Users via Command Prompt

1. Press Win + R to open the Run dialog box, type cmd, and hit Enter.

2. In the Command Prompt window, enter the following commands:

Code block

1 quser

2 query user

3. Review the results — if you see unfamiliar accounts currently logged in, it may indicate that your computer is being remotely accessed.

Method 2: Check Active Users via Task Manager
This is a straightforward and real-time way to view all logged-in users.

1. Press Ctrl + Shift + Esc to open Task Manager.

2. Go to the Users tab.

3. Review the list — under normal circumstances, you should only see your current account.

Method 3: Track Login History via Event Viewer
Event Viewer provides detailed system activity logs, making it perfect for tracing login behavior.

1. Search for and open Event Viewer from the Start menu.

2. Go to Windows Logs > Security.

3. Look for Event ID 4624 (Successful Logon) and check for suspicious remote login entries.

Detect Remote Control on macOS

While macOS uses a different approach, the underlying logic is the same — spotting signs of unauthorized access.

Method 1: Check Screen Sharing Settings

1. Go to System Preferences > Sharing.

2. Verify that Screen Sharing and Remote Login are turned off.

3. If these services are enabled without your knowledge, your system might be compromised — disable them immediately.

Method 2: Monitor Network Connections
Use the built-in Activity Monitor to observe network usage and identify any unusual activity.

How to Block Remote Control on Your Computer

Once you’ve confirmed that your computer is being remotely controlled, it’s time for emergency action. Whether you use Windows or Mac, these methods can help you cut off the connection and stop further control.

Stop Remote Access on Windows

Windows’ built-in Remote Desktop and Remote Assistance features are often exploited by hackers. Disabling them is the first step toward stronger protection.

Method 1: Disable Remote Desktop and Remote Assistance
This is the most direct way to block unauthorized access.

1. Press Win + R, type control, and hit Enter.

2. Go to System and Security > System > Remote settings.

3. In the Remote tab, uncheck Allow Remote Assistance connections to this computer.

4. Select Don’t allow remote connections to this computer and click OK.

Method 2: Adjust Windows Firewall Settings
Even after disabling remote features, you can add extra protection via the firewall.

1. Open Windows Defender Firewall.

2. Click Allow an app or feature through Windows Defender Firewall.

3. Click Change settings, then uncheck Remote Assistance and Remote Desktop.

4. Save your changes.

Method 3: Disable Unnecessary Remote Services
Use Services Manager to completely disable remote-related background services.

1. Press Win + R, type services.msc, and hit Enter.

2. Locate and disable the following services:

• Remote Desktop Services

• Remote Registry

• Telnet (if enabled)

3. Set their startup type to Disabled.

Stop Remote Access on Mac

macOS manages remote access centrally through System Preferences.

Method 1: Disable Remote Access Features

1. Go to System Preferences > Sharing.

2. Uncheck the following:

• Screen Sharing

• Remote Login

• Remote Management

• Remote Apple Events

3. Ensure all remote access options are turned off.

Method 2: Check and Remove Unknown Apps
Some remote control apps may be installed without your consent.

1. Go to the Applications folder.

2. Look for unfamiliar remote control software — such as TeamViewer, AnyDesk, or Chrome Remote Desktop.

3. If you didn’t install them yourself, remove them immediately.

How to Prevent Future Remote Control Attacks

Emergency actions alone aren’t enough — long-term protection is key. Building a multi-layered security strategy will greatly reduce your risk of remote access attacks.

Strengthen Authentication

• Use complex and unique passwords with uppercase, lowercase, numbers, and symbols.

• Enable two-factor authentication (2FA).

• Change passwords regularly and avoid using the same one across multiple services.

Manage Updates and Patches

In 2024, hackers exploited 768 vulnerabilities with CVE numbers — a 20% increase from 2023. Keeping your system updated is crucial.

• Enable automatic system updates.

• Regularly install security patches.

• Keep your antivirus definitions up to date.

Strengthen Network Security

• Use a VPN to encrypt your connection, especially on public Wi-Fi.

• Avoid unsafe public networks.

• Change your router’s default password and review settings regularly.

• Install reputable antivirus software with real-time protection.

• Run full system scans regularly.

• Use secure remote desktop software with encrypted connections.

In IT, there’s a universal truth: systems never break down when it’s convenient. It’s 3 AM. Your phone buzzes. A server just went rogue. The team’s halfway across the globe. And you’re under a blanket. That’s the reality of modern IT, distributed teams, hybrid work, and the need for always-on support.

The great news is, you do not need to be in the server room or burn the midnight oil keeping those systems running. The right remote monitoring & maintenance (RMM) solution gives you visibility into what's happening, enables you to resolve issues quickly, and even averts problems before they happen.

In this post, we explain the essence of RMM, why it has become so vital to IT teams today, and how it can assist you in managing ever-expanding systems in a secure, flexible as well as scalable manner from anywhere using DeskIn.

What is RMM?

Remote monitoring & maintenance, or RMM, is how IT teams can view and fix devices without being in the same room, or even country. You can remotely hop in there, spot what the problem is, and fix it in that location instead of walking right over someone’s desk in order to check why a PC is crawling.

What Does RMM Actually Do?

At its core, remote monitoring & maintenance is to keep your devices healthy and your users productive. It typically includes:

• Monitoring system health: Get a live look at CPU load, RAM usage, disk space, and even how apps behave over time. If someone’s laptop is overheating because 47 Chrome tabs are open, you’ll know.

• Detecting usage patterns:  Know what kind of alerts are being generated frequently and how systems/services are used, or misused, notice the pattern before it gets to your attention due to a production issue.

• Performing updates and diagnostics remotely: Patch security holes, push software updates, and run checks without waiting for someone to bring their device into the office; you can handle it all in real time.

Who uses RMM?

• IT helpdesks: Fix issues quickly without disrupting the user.

• Enterprise IT teams: Manage thousands of devices across multiple sites with ease.

• Managed Service Providers (MSPs): Deliver proactive support that keeps clients running smoothly.

In short, RMM transforms IT from reactive to proactive, letting teams maintain infrastructure without burning out or chasing tickets all day. And in 2025, with devices spread across homes, offices, co-working spaces, and even airports, remote monitoring & maintenance isn’t just helpful, it’s mission-critical.

Why Remote Monitoring Matters in 2025

The way we work has changed, permanently. Offices are optional, teams are global, and IT is expected to support everyone, everywhere, without skipping a beat. In this world, remote monitoring & maintenance isn’t just a convenience, it’s the glue holding modern work together.

Let’s break down why it’s more critical than ever in 2025.

1. The Remote and Hybrid Workforce Is Here to Stay

Back in the day, IT could stroll over with a USB stick and a screwdriver. Not anymore.

Now, your design lead works from a café in Seoul, your marketing team is spread across four cities, and your developer just hopped into a new time zone, again. Supporting this scattered crew means keeping eyes on every device, no matter where it’s plugged in.

That’s where remote monitoring & maintenance shines. It keeps systems visible, updated, and supported, whether users are at home, in the office, or somewhere in between.

2. Downtime Is Expensive

Every minute of downtime bleeds productivity, revenue, and trust. A laggy laptop during a client pitch, a frozen system mid-code deployment, those moments hurt.

With remote monitoring & maintenance, IT can act before trouble hits. You’re not waiting for someone to say, “Hey, something’s wrong.” You’ve already spotted the issue and fixed it before it derails the workday.

3. Real-Time Visibility Stops Bigger Problems

It’s the difference between noticing your car’s engine overheating while cruising on the highway or catching it in the driveway.

With real-time visibility, you can watch CPU spikes, memory leaks, overheating, or unusual activity as they happen. It’s like a live dashboard that lets you step in before small hiccups turn into full-scale crashes.

4. We Live in a Cross-Platform World

Windows, macOS, Linux, Android, iOS — today’s work devices speak different languages, and your monitoring tools need to be fluent in all of them.

With solutions like remote desktop, you can manage them all from one place. Whether it’s a MacBook in a music studio, a Windows desktop in a data center, or a mobile device in the field, remote monitoring & maintenance keep them all connected, secure, and running at their peak.
