Do you think someone is spying on you through your mobile phone? It could be your spouse, your boss, or even your government. While it may seem like something out of a spy movie, there are ways that someone can spy on your cell phone without installing any software.

Of course, one reliable method is to use a spy app. These apps are designed to track someone’s activities and report them back to the person who installed the app. There are many different spy apps available, and they can be installed on both iPhone and Android devices.

However, there are also many ways that someone can spy on you without installing software. In this article, I’ll discuss all of them as well as how you can protect yourself from such attacks!

10 Ways To Spy On A Target Phone Without Installing Software

Through Social Engineering

Social engineering is a term that refers to the act of manipulating someone into performing a desired action.

In the context of spying, social engineering would involve convincing the target to give up important information, such as passwords or other login information.

Some can even use social engineering to get you to install a phone monitoring app on your own device.

For instance, maybe they pretend to be a developer of social media apps and offer a free trial of new features. Or maybe they send you a link that claims to be a new game or something else exciting, but it’s really a phone spy app in disguise.

Whatever it is, social engineering is a very real threat and something that you should be aware of. If someone is trying to get you to do something that you’re not comfortable with, don’t hesitate to question their motives.

By Intercepting Your Communications

Another way that someone can spy on your cell phone is by intercepting your communication, such as your calls or text messages. This can be done either through the use of software or app or by physically tapping into the target phone.

If your calls are being intercepted, it’s possible that the person listening in could record your conversations and even listen to them live. They might also be able to see any text messages that you’re sending or receiving.

Similarly, if your text messages or emails are being intercepted, the person could read them and even reply to them without you knowing.

By Accessing Your Voicemail

Another way that someone can spy on your cell phone is by accessing your voicemail. If they have your phone number and PIN, they can easily call into your voicemail and listen to any messages that you’ve saved.

They might also be able to change your voicemail greeting or even delete messages that you’ve already heard.

Obviously, this is a problem because it gives the person access to all of your private messages, even if you’re not currently using your phone.

Phishing is a type of online scam where someone tries to trick you into giving them personal information, such as your passwords or credit card numbers.

It’s similar to social engineering, except this one doesn’t require the use of a human behind the screen. It also doesn’t need a phone spy app installed on your Apple or Android device for it to work.

For instance, people who want to spy on you via phishing may use bots to send an email that looks like it’s from a legitimate website, including social media apps like Facebook or Whatsapp. The email then asks you to enter your login information so that they can “verify” your account.

Of course, once you enter your information, you’ve basically given them free access to your account. It also means they can do whatever they want with it. They might even be able to use it to spy on you further by accessing the personal data on your social media apps or iPhone and Android devices.

Using Cloud Backup Services

If you use a cloud backup service like iCloud or Google Drive, then it’s possible that someone could access your backups without ever having to physically touch the target device.

For example, if they know your iCloud username and password, they can log in using spy apps and view all of your backups on the target phone.

This includes any photos, videos, or text messages that you have stored in the cloud. They might even be able to download these files and view them on their own devices.

It’s the same if you have an Android phone with Google backups enabled. The spy will be able to see all of the data that you have stored in the cloud and do whatever they want with it.

In 2014, a huge scandal broke out in the United States when an anonymous group began leaking private photographs of roughly 500 celebrities, mostly women, that contained nudity.

The thread first started on the imageboard 4chan, and the photos were later on reuploaded in various places on the Internet, including network websites like Reddit. Later on, it was discovered that the photos came from the celebrities’ hacked iCloud accounts.

By Using A Spy App

There are some spy apps that don’t need to be installed on the phone in order to work. Apple users are more at risk for this.

For instance, phone spy apps like mSpy, Kidsguard Pro, or XNSpy only need your iCloud email address and password in order to spy on you. The spy doesn’t even have to touch the target phone in order to start spying.

With these paid apps, they can look at anything in your iCloud through their desktop dashboards, such as your social media apps. Some apps can even see your location because they can also access the GPS on the target phone.

While this already sounds scary enough, it gets even scarier when you find out that there are also free spy app alternatives. This means that anyone can spy on everyone else, provided that they also have this knowledge.

Luckily, Android phones seem to be well-protected against this type of remote attack. A phone spy app typically needs the Android device on hand before it can be installed.

This means that the spy must have your Android device physically for them to install the spy app, unlike an iPhone, which can be accessed fully remotely.

Through Wireless Networks

Occasionally, people leave their wireless networks unencrypted, which means that anyone can join them and access the Internet.

If you’re using an unsecured wireless network on the target device, then it’s possible for someone to spy on your traffic. This means that they can see the websites that you’re visiting, the data that you’re sending, and even your login information if you’re not using HTTPS.

Obviously, this method doesn’t need a phone spy app in order to access data on the target phone, so you should be careful.

By Hacking Your Phone’s Operating System

It is possible to remotely hack someone’s phone by taking advantage of a security flaw in the target device’s operating system.

For instance, in 2015, a major exploit was discovered in Android called Stagefright. This exploit allowed hackers to remotely take over an Android phone by sending a malicious video message. All the hacker needed was the number of the target phone in order to send the message.

While Stagefright has since been patched, there are bound to be other security flaws that have yet to be discovered. This means that it’s possible for someone to remotely hack your phone and spy on you, even if they don’t have physical access to the target device.

By Using A Spoofed MAC Address

A MAC (Media Access Control) address is a unique identifier that is assigned to every device on a network.

Normally, MAC addresses are hard-coded into the hardware of the devices. However, it is possible to spoof, or change, your MAC address so that it appears as if you have a different MAC address.

If you’re connected to a public Wi-Fi network, then someone can spoof their MAC address so that it appears as if they’re using your device. This allows them to spy on the traffic of your iPhone or Android phone and see what you’re doing online.

By Using A Man-In-The-Middle Attack

A man-in-the-middle attack is a type of attack where the attacker intercepts communication between two parties.

For instance, let’s say that you’re trying to visit a website. Normally, your phone’s browser would send a request to the server and the server would send back the website. However, in a man-in-the-middle attack, the attacker intercepts the communication between the target phone and the server.

This means that the attacker can see what websites you’re trying to visit on your iPhone or Android phone and they can even modify the website before it’s sent back to you. This allows them to insert their own malicious code into the website, which can be used to spy on you.

Keeping Yourself Safe From Online Spies

Now that you know the answer to “how can I spy on a cell phone without installing software or a phone spy app,” you might be wondering how you can protect yourself from such attacks.

Fortunately, there are a few things that you can do to reduce the chances of someone making you their target phone.

Be Careful Of What You Install

As I mentioned earlier, one of the most common ways for someone to spy on you is by installing a phone spy app on your Apple or Android device.

This means that you should be careful of what apps you install on your phone, regardless of its operating system. Remember, both iPhones and Android devices can allow spy apps to be installed.

Only install apps from trusted sources. If you have an iPhone, this means downloading only from the Apple App Store, and if you have an Android device, only the Google Play Store.

If you’re not downloading from these platforms, make sure that you know the developer and that the app is completely safe.

Avoid downloading apps from unknown websites, as these could be fake versions of legitimate apps that have been modified to include spyware. It’s not uncommon to hear stories about people installing something only to find out that it’s actually a spy app in disguise.

Keep Your Software Up To Date

As I mentioned earlier, there are plenty of ways for someone to start spying on you through your cell phone without ever touching it, let alone installing a spy app.

One of the more sophisticated methods is taking advantage of security flaws in the operating system of the target device. This is especially true if you have an Android phone.

Android devices are particularly at risk since iPhones tend to have better security. Google makes many aspects of its Android operating system open-source to promote innovation. However, the downside is that it makes an Android device much more prone to this type of attack than an iPhone.

That’s why it’s important to keep your software up to date. Old and outdated software is easy to target for hackers because they’re already familiar with how it works. New hacks and bugs are being discovered all the time, which is why developers have to regularly patch their software to fix these flaws.

When a new security patch is released, make sure to install it as soon as possible. This will help to protect you from any new exploits that might be discovered.

Create Backups Of Your Data

If you’re worried about someone spying on your iPhone or Android phone with a spy app or something similar, then it’s a good idea to create backups of your data. This way, if your phone is ever hacked, you’ll still have a copy of your data stored safely elsewhere.

There are a number of different ways that you can create backups of your data. You can use a cloud storage service, such as Google Drive or Dropbox or both. Or you can use an external hard drive or USB flash drive.

Whichever method you choose, make sure that you encrypt your backups so that anyone who tries to access them without your permission won’t be able to. Even a spy app wouldn’t be able to access your data if it’s fully encrypted elsewhere.

Use A Password Manager

All cybersecurity guides say that we should use strong passwords that are hard to crack, but we know that this is easier said than done. After all, nine times out of 10, a password that hackers can’t guess is also a password that is too difficult and complex to remember.

This is where a password manager comes in. A password manager is a tool that stores all of your passwords in one secure location. That way, you only have to remember one master password, which gives you access to all of your other passwords.

Another good reason to use a password manager is that it protects you against keyloggers, which many spy apps have.

Without a password manager, you’ll have to type your password every time. Many spy apps have a keylogger, which, as the name implies, logs all your keystrokes. This will make your password completely visible to spies, putting you at risk.

To protect yourself from this common feature of spy apps, make sure you use a good password manager. There are many options to choose from, such as LastPass and 1Password. They all work the same way: you create an account with the password manager and then add all of your other passwords to it.

When you want to log in to a website, the password manager will automatically fill in the correct password for you, rendering the keylogger function of many spy apps useless.

And if you ever need to change a password, you can do it from within the password manager as well. Of course, if you suspect that your phone is already bugged with spy apps, make sure you do this from another device.

Use 2-Factor Authentication

Two-factor authentication (2FA) is an extra layer of security that requires you to not only enter your password but also to confirm your identity with a second factor. This adds an extra step to the login process, but it also makes it much harder for someone to hack into your account.

It’s especially important for iPhone users since iCloud accounts are notorious for being very vulnerable to spy apps.

As mentioned above, there are many spy apps that only need your iCloud email address and password in order to remotely gain access to your entire account. Enabling 2FA can help protect you against that, or at least make it harder for people who use spy apps to make your device their target phone.

The second factor to 2FA can be something that you know, such as a PIN or an answer to a security question. Or it can be something that you have, such as your phone or a physical token.

Google even has an app called the Google Authenticator, which generates a new code every 30 seconds. There are also plenty of alternatives for both iOS and Android devices, so you might want to look into that.

You can enable 2FA for your email account, social media accounts, and even your online banking. If a website offers 2FA, we highly recommend that you enable it.

Don’t Open Random Messages

It’s great to live in a world where we can stay connected with our friends and family no matter where we are. But this also means that we’re more vulnerable to attacks from hackers who use social engineering to get us to do whatever they want.

These cyber-crooks use psychological tactics to lure you into doing things you might otherwise not do. For example, they might pretend that they’re from a company you know and trust and then ask you to click on a link or download an attachment. Or, they might create a fake social media profile and then message you out of the blue.

Either way, their ultimate goal is to get you to do something that will give them access to your accounts or your personal information, such as installing a spy app on your own phone. So, it’s important to be aware of these social engineering tactics and to never respond if someone you don’t know suddenly messages you.

Don’t Click Strange Links

We’ve all gotten those random emails or messages from someone we don’t know, promising us a million dollars if we just click on the link. Maybe they’re claiming to be from our bank, asking us to enter our login details.

These are called phishing scams, and they’re designed to trick you into giving away your personal information. They’re usually pretty easy to spot, but sometimes they can be quite convincing.

Unfortunately, it’s not difficult at all to hack into a target phone using phishing.

If you ever receive a message from someone you don’t know that contains a link, don’t click on it. And if you’re ever asked to enter your personal information on a website, make sure that you’re on the correct website by checking the URL.

Don’t Open Unknown Attachments

It’s not just links that you should be careful of – you should also be cautious of email attachments.

If you receive an attachment from someone you don’t know, don’t open it. It could contain a spy app that will install itself onto the target phone. Worse, it may contain malware that will infect your iPhone or Android device.

The same goes for email attachments from people you do know. If you’re not expecting an attachment, it’s best to check with the person before opening it. That way, you can be sure that it’s safe.

Back in 2000, a computer virus called the ILOVEYOU bug, often shortened to Love Bug, wreaked havoc on computers around the world. The virus was spread through email attachments.

Once a person opens the infected attachment, the virus would send itself to everyone in their address book. It caused billions of dollars in damage, including shutting down the email systems of major corporations.

Although the virus wasn’t known to target iPhones or Android devices, it’s still something we should all learn from.

Avoid Connecting To Public Networks

When you’re out and about, it can be tempting to connect to a public Wi-Fi network so that you can save your data. But this is a bad idea for several reasons.

First of all, public Wi-Fi networks are often unsecured, which means that anyone can snoop on the traffic going through the network. This means that if you’re sending any sensitive information, such as your login details or credit card number, it could be intercepted by a hacker.

Secondly, public Wi-Fi networks are often used by cyber-crooks to spread malware. They might create a fake Wi-Fi network and then lure people into connecting to it. Once you’re connected, they can then infect your device and wreak havoc.

So, it’s best to avoid public Wi-Fi networks in general and to use your mobile data instead. If you don’t have mobile data or if you can’t get sufficient signal, you can also make it a habit to bring pocket wifi or router with you instead.

If you’re worried about someone spying on your traffic on your iPhone or Android device, then you can use a VPN or virtual private network.

A VPN encrypts your traffic so that it can’t be read by anyone, even if they are intercepting your communication. This is especially useful if you’re using public Wi-Fi.

A VPN can also help you to bypass firewalls and internet censorship. For instance, a VPN can help you connect to Netflix and watch films and series from libraries that are only available to other countries. And it can give you a measure of anonymity online by hiding your real IP address.

There are many VPNs to choose from, and some are better than others. Our top recommendation is NordVPN, which is fast, easy to use, and very secure.

Don’t Give Your Phone To Just Anyone

This one might seem obvious, but it’s worth mentioning. If you don’t want someone to spy on you through your phone, then don’t let them have your phone.

It might be tempting to let a friend or family member borrow your phone, but if you’re worried about someone snooping on your device, it’s best to say no.

The same goes for anyone else, even if they’re someone you trust. Remember, all they need is a few minutes and they can already install spyware on the target phone.

Don’t Overshare On Social Media

If you’re not careful about what you share on social media, you could be giving away more information than you realize.

For instance, if you share your location on social media, you could be making it easy for someone to track your movements.

In fact, many cyber criminals who use social engineering tend to look for targets on social media. If they see that you’re frequently posting about your whereabouts, they might make you their next target device for installing a spy app.

The same goes for sharing other personal information, such as your address, phone number, or email address. If you wouldn’t give that information to a stranger, then don’t share it on social media.


Can I spy on a mobile without installing applications on it?

You can spy on a mobile phone without installing spy apps. There are a few ways to do this, such as using their iCloud login or taking advantage of security vulnerabilities in the operating system. However, these methods are not always reliable and they may not work on all devices.

Is it legal to spy on a mobile?

Determining if it’s legal to spy on a mobile depends on a number of factors. In most cases, it’s legal to install a spy app on a mobile phone if you own the target device or if you have the target phone owner’s permission. Of course, there are also exceptions.

How can I prevent someone from spying on my mobile?

You can prevent someone from spying on your mobile, whether that’s by installing a spy app or using another method. These include being careful of what apps you install on the target device, using a VPN at all times, and keeping the software of the target phone up to date.
