Can Someone Access My Computer Remotely Without Me Knowing?

Can someone access my computer remotely without me knowing?

Unfortunately, yes — and it's one of the most deceptive and dangerous cyber threats today. Remote access technology allows users to control a computer from a different device or location — useful for remote work or remote IT support. However, hackers can exploit these same tools to spy on your system, often without your knowledge.

Remote access scams often begin with criminals tricking unsuspecting users into granting them control. Once they gain entry, your private files, personal identity, and even financial information can be compromised. Knowing how to see if someone is remotely accessing your computer is essential to keeping your digital life secure.

This guide walks you through the warning signs that someone may be secretly viewing or controlling your computer, and what steps you can take to safeguard your privacy, data, and money from cybercriminals. Whether you’re wondering can someone access my computer remotely without me knowing or simply want to learn how to check for hidden intrusions, the information below will help you stay protected.

How Do Remote Access Scams Work?

Remote access scams typically unfold when cybercriminals deceive users into granting them control of their computers. While some hackers rely on advanced tools and coding skills, most prefer a simpler approach, manipulating people through social engineering. Instead of breaking in, they trick you into opening the door yourself.

A classic example comes from an FBI alert warning about fake tech support calls. Scammers pretended to be representatives from well-known companies like Microsoft or Amazon, convincing victims to install remote access programs that secretly gave criminals full control of their systems.

Here's how such scams usually unfold:

• Fake tech support reaches out: You might get a phone call, text, or email from someone claiming to be from a trusted company. Sometimes, scammers even plant fake customer support numbers online, hoping you'll contact them first.
• They create a false sense of urgency: Once they have your attention, these impostors warn that your computer or account has been compromised. Their goal is to make you panic so you'll comply quickly. They may claim your device is infected with a virus or that your bank account is being targeted.
• They convince you to install a remote access tool: Posing as helpful technicians, they ask you to download a remote desktop program such as AnyDesk, TeamViewer, or RemotePC. The moment you grant permission, they gain the same control over your computer that you have.
• The hacker takes full control: With remote access established, the scammer can browse files, capture sensitive data, change settings, and even log in to your email or bank accounts.
• You're locked out, and extorted: Some scammers take it further by altering your passwords or deploying ransomware to block access. They may then demand money or cryptocurrency before restoring control.

Protecting yourself means staying cautious. Never trust unsolicited tech support messages or calls. If someone insists you install remote software to “fix” an issue, hang up immediately and verify directly through the company's official website.

Stay safe online: Use trusted security tools and monitor your accounts for suspicious activity. Strong digital protection is your first line of defense against remote access scams.

How to detect remote computer access (5 simple steps)

If you’re trying to learn how to check if someone is remotely accessing your computer Windows 10 or any other operating system, the steps below will help you confirm whether your device has been compromised.

1. Watch for Obvious Signs of Intrusion

Not all hackers hide in the shadows, many leave behind digital footprints that are easy to spot if you know what to look for. Here are some clear indicators that someone might be remotely accessing your computer:

• Unusual account activity: If you notice unauthorized logins, new user profiles, or unexpected changes to your personal details, it could mean someone has gained access to your accounts and is making alterations behind the scenes.
• Mysterious mouse movements: A moving cursor that you didn't touch is a major red flag. In one well-known case, a Florida water plant worker prevented a cyberattack after spotting unexplained mouse movements on his screen, proof that vigilance pays off.
• Slow or overheating devices: Remote intruders often drain system resources by transferring data or installing malicious software in the background. If your computer suddenly becomes sluggish or unusually warm, it may be working harder than it should because someone else is using it too.
• Strange pop-ups or random command windows: A flood of unexpected pop-ups or spontaneous Command Prompt activity could signal a hidden connection or a malicious process running on your system.
• Repeated antivirus alerts: Multiple warnings from your security software shouldn't be brushed off. They could be your system's way of flagging unauthorized access attempts.
• Active microphone or webcam: If your mic or camera light turns on when you're not using them, it's a serious warning sign. A hacker could be remotely spying or recording without your consent.

Spotting even one of these red flags should prompt immediate action, disconnect from the internet, run a full security scan, and investigate further to secure your system.

2. Review recent activity on your computer

If someone has gained remote access to your device, traces of their activity will often appear in your system records or browser history. By reviewing these areas, you can quickly identify suspicious behavior that might indicate an intrusion.

Here's how to inspect your device for unusual activity:

Check recently opened files and applications.

• Windows: Open the Start menu and look under Recent apps to see which programs were accessed most recently.
• Mac: Click the Apple icon in the top-left corner, then select Recent Items to view files and apps that have been opened.
• Browsers: Review your browsing history for websites, downloads, or extensions you don't recognize. In Google Chrome, you can open My Activity to see all recent searches, websites, and downloads, take note of anything suspicious or out of place.

Look for unusual login attempts.

Failed or late-night login attempts can signal that someone is trying to access your computer remotely.

• Windows: Go to Control Panel > System and Security > Administrative Tools > Event Viewer. On the left panel, click Security to review all recorded login events.
• Mac: Apple doesn't include a built-in login history viewer, but you can use trusted third-party monitoring tools to check for remote connections or unauthorized logins.

Inspect system logs for remote access activity.

• Windows: Press Windows + R, type `eventvwr`, and hit Enter to open the Event Viewer. Here, you can browse through logs that record every system action, including remote access events.
• Mac: Open Finder, go to Applications > Utilities, and launch Console. Review the system logs for unfamiliar IP addresses or connection records.

Regularly reviewing these logs and histories helps you detect intrusions early, before hackers can steal sensitive information or cause serious damage.

3. Look for installed remote access programs

If you suspect that someone might access your computer remotely without you knowing, one of the quickest ways to confirm it is by checking for remote access software installed on your system. Cybercriminals often use legitimate toolsto gain and maintain control over a device without raising immediate suspicion.

Here's how to identify them:

Check active processes.

• Windows: Press Ctrl + Shift + Esc to open Task Manager. Review the list of active applications and background processes. If you see remote access tools running that you didn't install, it's a strong indicator of unauthorized activity.
• Mac: Press Command + Space, type Activity Monitor, and hit Enter (or click the magnifying glass icon and search for it). Once open, browse through active apps and processes for any unfamiliar remote connection tools.

Search your installed applications.

• Windows: Go to Control Panel > Programs > Programs and Features to view all installed software. Carefully scan the list for names like AnyDesk, TeamViewer, RemotePC, or LogMeIn.
• Mac: Open Finder, select Applications, and review the folder for any remote desktop apps that you don't recognize.

If you find a program you don't remember installing, don't open it. Disconnect from the internet, uninstall the software, and run a full malware scan. Removing unauthorized remote access tools quickly is key to preventing further breaches.

4. Review your firewall settings

A properly configured firewall acts as a barrier between your computer and unauthorized users. However, if scammers already have remote access, they may quietly alter your firewall rules to create hidden entry points, allowing them to reconnect whenever they want. Checking your firewall settings can help uncover and block these backdoor connections.

Here's how to review your firewall configuration:

• For Windows users:

Step 1. Press Windows + X and open the Control Panel.

Step 2. Go to System and Security > Windows Defender Firewall > Advanced Settings.

Step 3. In the left-hand panel, examine both Inbound Rules and Outbound Rules for unfamiliar or suspicious entries.

Step 4. If you see a rule that doesn't look legitimate, right-click on it and select Disable Rule to block the connection temporarily.

Step 5. Before deleting or permanently disabling any rule, research its purpose, some may belong to trusted programs.

• For Mac users:

Step 1. Click the Apple menu and open System Preferences.

Step 2. Select Security & Privacy, then go to the Firewall tab.

Step 3. If your firewall is turned off, click the padlock icon at the bottom left, enter your administrator password, and enable it.

Step 4. Click Firewall Options to view all allowed applications and services.

Step 5. Carefully review this list for unknown or suspicious items. To block an unwanted connection, uncheck the box next to the corresponding application.

Regularly auditing your firewall rules ensures that only trusted programs have permission to communicate with your system, keeping intruders locked out and your data protected.

5. Run a comprehensive antivirus scan

Hackers often rely on malicious software to infiltrate devices, steal credentials, and maintain hidden access to your system. Running a trusted antivirus scan is one of the most effective ways to detect and remove these threats before they cause serious harm.

A reputable antivirus solution continuously monitors your device in real time, blocking suspicious programs, phishing attempts, and unauthorized remote connections. It acts as your first line of defense, identifying and isolating malware that could allow hackers to take control of your computer.

Be cautious, though, avoid using free or unknown antivirus or “PC cleaner” tools, as many of them disguise malware or spyware within their downloads. Instead, choose a reliable cybersecurity solution from a well-known provider like Aura, which offers advanced protection and ongoing monitoring against evolving digital threats.

Protect your identity and data: If a hacker has already accessed your computer, your personal and financial information may also be at risk. Using tools like Identity Guard can help you detect potential identity theft early, monitor sensitive data in real time, and provide up to $1 million in insurance for fraud-related losses.

What to do if you suspect an unknown remote admin

If you suspect that someone has gained unauthorized access to your computer, acting quickly is crucial to protect your data, accounts, and devices. The following steps will guide you in securing both Windows PCs and Macs.

1. Disconnect from the Internet Immediately

Unplug your Ethernet cable or turn off Wi-Fi to cut off the hacker's connection. While some malware can still operate offline, a full computer shutdown is the safest approach to prevent further unauthorized access.

2. Change All Passwords Using a Secure Device

Avoid using the compromised device to update your passwords. Keyloggers or spyware may record your new credentials. Instead, use a trusted device, such as your smartphone or a friend's computer, to create strong, unique passwords for email, social media, banking, and all other online accounts.

3. Run Antivirus Software and Remove Suspicious Programs

Scan your system for malware and review all installed programs. Delete any applications you don't recognize or trust.

• Windows: Check installed programs via Control Panel > Programs > Programs and Features.
• Mac: Review your Applications folder for unknown software.

4. Back Up Your Files and Wipe Your Device

Performing a factory reset removes hidden malware and restores your system to its original state. Before wiping, back up important files to the cloud or an external hard drive to prevent data loss.

5. Secure Your Wi-Fi Router

Hackers can exploit network vulnerabilities to access other devices on your home network. Protect your router with these steps:

• Change default login credentials and use long, complex, unique passwords.
• Disable remote administration to prevent outside access.
• Enable WPA3 encryption; if unavailable, use WPA2.
• Update your router's firmware to the latest version to patch security gaps.

Taking these precautions not only removes the intruder from your system but also strengthens your overall digital security, reducing the risk of future attacks.

How to prevent future remote access attacks

Taking a proactive approach is the most effective way to protect your devices from unauthorized remote access. Strengthening your cyber hygiene now reduces the likelihood of falling victim to hackers in the future.

1. Use a Password Manager

Weak or reused passwords contribute to roughly 80% of security breaches. A dedicated password manager makes it simple to generate, store, and autofill strong, unique passwords for every account, eliminating the risk of using easily guessable credentials.

2. Enable Multi-Factor Authentication (MFA)

Adding a second verification step dramatically improves account security. Options such as authenticator apps, fingerprint scans, or security tokens ensure that even if your password is compromised, hackers cannot gain access without the additional verification.

3. Use a Virtual Private Network (VPN)

A VPN encrypts your online activity, masking your location and protecting your data from interception. By securing your internet connection, a VPN makes it much harder for cybercriminals to remotely access your computer.

4. Keep Software and Apps Up to Date

Regular updates patch security vulnerabilities that hackers exploit. Enable automatic updates when possible and always download software only from official sources. If an update causes issues, most programs allow you to roll back to a previous version safely.

5. Stay Vigilant Against Phishing

Phishing remains one of the most common ways scammers gain unauthorized access. Be cautious of suspicious emails, links, or attachments. Staying informed about emerging phishing tactics can prevent identity theft. In 2022 alone, Americans lost $40 million to phishing scams.

6. Report Suspicious Activity

If you experience unauthorized remote access, report it to authorities like the Federal Trade Commission (FTC). Gather evidence, such as screenshots, to help investigators track down cybercriminals and protect others.

Even devices known for strong security, like iOS and macOS, are not completely immune. Hackers can target Macs and other systems alike.

For comprehensive protection, consider tools like Identity Guard, which offer identity theft protection, monitor sensitive data, and safeguard devices and finances against cyber threats. Staying vigilant and using advanced security solutions keeps you one step ahead of scammers.
