Codes to Check if Phone is Hacked or Tapped

Has your phone been hacked? If you're not sure, there are ways to find out. 

With USSD codes, also known as quick codes or feature codes, you can quickly check if your phone has been hacked. There are many combinations to diagnose different issues, and with code to check if your phone is monitored, you can be sure you're safe.

There are other diagnostic methods too, and a bunch of methods and techniques you can use to diagnose and rectify any potential hack to your smartphone. 

You may have the latest iOS or Android device, and be confident no one can hack your phone. But the global security situation would say different, and if you're trying to figure out what to dial to see if your phone is hacked, you're in the right place. 

With everything going on in the world, cyber-attacks are becoming increasingly common, and one way to prevent them is to learn white hat hacking.

What To Do If You Think Your Phone Has Been Hacked

First and foremost, if you have a feeling or suspicion that your phone has been hacked, it's always better to err on the side of caution. 

Start by changing all your passwords for any accounts accessed through your device and your phone's lock screen password. This can prevent further access to your personal information. 

Next, consider whether there may be any sensitive information on your device that could potentially be compromised. If so, think about how you can protect that information and who needs to be notified of the potential breach. 

It would be best if you also considered contacting your service provider, as they may have resources and assistance to secure your device. 

With USSD codes, you can also easily check for any unusual activity on your phone, such as unexpected data usage or strange texts and calls.

The Signs That Your Phone May Have Been Hacked

1. Unexplained Data Usage

One of the first things you might notice if your phone has been hacked is unexplained data usage. If you have a data limit on your plan and you find yourself going over it for no apparent reason, it could be because someone is using your data without your knowledge. 

Hackers can install malware on your phone that uses your data in the background without your knowledge.

 To check for unexplained data usage, look at your phone's data usage history in the settings app. If you see any apps using more data than usual, or if there's data being used when you're not even using your phone, those could be signs that your phone has been hacked.

2. Unexpected App Activity

Another sign that your phone may have been hacked is unexpected activity from apps that you don't use very often. If you see notifications or other activity from an app that you barely ever use, there's a chance that someone has installed malware on your phone and is using that app to spy on you or steal information from you. 

To check for unexpected app activity, go through the list of apps on your phone and see if there are any that you don't remember installing or that you haven't used in a long time. If you see anything suspicious, delete the app right away. 

Hackers will sometimes install malicious apps (particularly web apps) on your phone without your knowledge to gain access to your personal information or steal sensitive data like login credentials and banking information. 

These are usually website domain applets and can lead to scripts running on your smartphone. You can also learn how to hack a website to counter such things.

3. Battery Drainage

If your battery starts draining unusually quickly, it could be another sign that something is wrong with your phone. This is usually caused by malware running in the background and can be confirmed by checking your battery usage history in the settings app. If you see an app that's using up a lot of battery power even when you're not using it, there's a good chance that it is malicious software and your phone has been hacked.

4. Slow Performance

A final sign that something might be wrong with your phone is if it starts running slowly or acting strangely. 

Several things can cause this, but if you suspect your phone has been hacked, it could be because there's malicious software running in the background and causing problems with how your phone runs. 

To check for this, open up the settings app and go to the "About Phone" section. Then look at the "System Updates" section and see if any updates are available for your operating system and apps. If there are, install them immediately, as they might contain security patches that will help protect your phone against hackers.

 

5. Suspicious Text Messages Or Calls 

If you start receiving text messages or calls from numbers you don't recognize, or if your friends and family start telling you they've been receiving strange texts or calls from your number, it's a sign that your phone may have been hacked. Hackers often spoof your phone number to access your contacts list, send spam messages, or make unwanted calls.

What Are USSD Codes?

USSD codes, also known as "Unstructured Supplementary Service Data" codes, are shortcodes that can be entered into a phone to access various features and information. These codes are commonly used for checking account balances, activating services, and troubleshooting technical issues.

It's important to note that USSD codes can potentially give hackers access to sensitive information on your phone, so it's essential only to use trusted sources and never share them with anyone else.

USSD Code To Check If Phone Is Hacked 

USSD codes usually begin with * or # and can be entered by simply holding down the * or # key on your phone and then entering the code. USSD codes can be used to check your balance, recharge your account, or even send money to another mobile phone user. 

To use a USSD code, simply enter the code into your phone and wait for the response. The response will usually be in the form of a pop-up message on your screen. In some cases, you may need to enter additional information, such as your PIN number, before the service can be accessed.

For Being Hacked

*#06# - This code will show you the IMEI number of your phone. The IMEI number is a unique identifier assigned to every mobile device. If you see a different IMEI number than the one usually associated with your phone, it's possible that your phone has been hacked.

*#062# - This code will show you the date when your SIM card was last updated. If you see a date you don't recognize, or if the date listed is significantly different from when you last remember updating your SIM card, your phone may have been hacked.

*#21# - This code will show you a list of numbers your calls have been forwarded to. If you see any numbers listed that you don't recognize, or if your calls have been forwarded to a number you didn't set up, it's possible that your phone has been hacked.

For Being Tapped

*#*#1472365#*#* - This code will show you if anything abnormal is happening with your device's GPS location. If someone has enabled GPS spoofing, this code will let you know. GPS spoofing is a type of hack where the hacker tricks your phone into thinking it's somewhere it's not. This can be used to track your movements or intercept your calls and text messages. To check if your phone has been hacked in this way, simply enter the code into your dialer and hit send. If everything appears normal, you're good to go. If not, it's time to start taking steps to secure your device.

*#*#7780#*#* - This code will help you reset your device to its factory settings. This is useful if you suspect your phone has been hacked and want to start from scratch. Keep in mind that this will delete all of the data on your device, so be sure to back up any important files before proceeding. To reset your device, simply enter the code into your dialer and hit send. Follow the prompts on your screen, and voila! Your device will be as good as new.

*#*#34971539#*#* - If you've ever looked at your phone's camera and thought someone might be peering in back, you can check to see if your suspicions ring true or not. This code gives you access to information about the camera hardware, including when it was last used and what type of camera it is. Simply enter the code into your dialer and hit send to view this information. If you see any unusual activity, it's a good indication that someone has been using your camera without your permission.

*#*#197328640#*#* - This code gives you access to your device's network information, including the signal strength and cell towers in use. While these codes may not definitively tell you whether or not your phone has been hacked, they can give you a good indication of any strange activity on your device. If you see any unusual activity here, it might signal that someone is monitoring or tampering with your network connection. If anything looks off, it's essential to take steps to secure your phone and protect your personal information.

Tips On How To Block Hackers From Your iOS Or Android Phone

  1. Update Your Software Regularly: One of the best ways to protect your phone from hackers is to ensure you're running the latest operating system version. That's because developers are constantly working to patch up vulnerabilities that could be exploited by malicious software or attackers. So, if you're not running the latest version of iOS or Android, you could be leaving yourself open to attack.
  2. Use a Secure Lock Screen Pattern or Password: Another simple way to beef up your security is to use a strong lock screen pattern or password. That way, even if someone does manage to get their hands on your device, they'll still have a hard time accessing your information. Remember that patterns can sometimes be guessed, so a long and complex password is usually the best option. Also, avoid using easily guessed words like "password" or easily accessible personal information like your birthdate.
  3. Install Security Apps: Many different security apps are available for iOS and Android devices. These apps can help block malicious software and even alert you if your device is being tampered with. Many of them are free, so there's no excuse not to have one installed. Just be sure to do your research before installing anything, as some security apps have been known to contain malware themselves. 
  4. Beware of Public Wi-Fi Networks: When you're out and about, connecting to public Wi-Fi networks can be tempting to save your data plan. However, these networks are often unsecured, which means they're prime targets for hackers. So, unless you absolutely need to connect, it's best to steer clear of public Wi-Fi altogether.

Conclusion

Ideally, there’s a lot of security in the latest smartphones, but hackers aren’t dumb either. They are in a constant race of cat and mouse with software updates. You should always stay up to date with software updates in your smartphone, especially Android given its open-source system origins. 

Irrespective of your mobile system, if you notice any signs, be sure to follow the steps above.
