Note that WhatsApp has implemented a high level of security to the extent that for a hacker to be able to get into your WhatsApp account, they would have to spend a significant amount of time and resources.

Therefore, the highest possibility of your account being hacked is that the intruder had access to your phone or any other device that you use for your WhatsApp.

By the end of this post, you’ll be able to recognize if there’s an intruder on your WhatsApp account, learn how they could get into your account and what you can do to prevent it, and you’ll also learn what you can do to get back control of your account in case you have been hacked.

Ways hackers might access your WhatsApp account

First, here are a few methods unauthorized users might utilize to access your account:

  1. WhatsApp Web

Through its Whatsapp Web feature, WhatsApp gives you the option to sync your contacts and chats to your computer,

This way you can access and use your account from both your desktop and your smartphone at the same time, or choose whichever device is most convenient for you at a given time. 

However, WhatsApp web also makes it pretty easy for an intruder to gain access to your account from one of your active devices.

The moment someone gets access to your device, especially your phone, they can quickly scan your WhatsApp QR code, and access your WhatsApp conversations in that short time.

Even worse, they’re also able to use WhatsApp Web from a different computer than yours after they’ve gained access to your account.

So this gives anyone the possibility to access your Whatsapp account from anywhere in the world for as long as they can access your WhatsApp QR code.

  1. Access to your device backup file

This works even when you have locked your WhatsApp with AppLock. However, note that this hack affects only those devices that do not have the recently updated WhatsApp.

When a hacker gets access to your device, within minutes they will be able to read or even delete your WhatsApp conversations from another device.

After getting your backup file using the file manager, they can send it via Bluetooth to another device.

They can use auto-backup apps like backup text for WhatsApp and directly email all your WhatsApp conversations in plain text by installing this app on your device, and when they are through they uninstall it.

  1. Through a public Wi-Fi network with a WhatsApp sniffer

Just like it is risky to use your email account on a public wifi network, it is also possible for your WhatsApp to be compromised with the WhatsApp sniffer via a public wifi network.

This is because every device has a unique Mac address and if the hacker gets to spoof your Mac address, then he will be able to see all your WhatsApp activity.

  1. Using Third-party Spyware

There are some third-party apps which claim to hack WhatsApp conversations. Apps like Spyzie often require the intruder to install a small piece of software on your device, which enables them to get into your WhatsApp conversations.

Unexplained Battery Consumption

If your smartphone battery drains so quickly by just leaving it on mobile data or wifi, then there is a possibility of spy software running on your smartphone without your consent.

Another notorious way someone can gain access to your WhatsApp account is by obtaining the text verification code. If WhatsApp sends you a text verification code that you didn’t invoke, it’s best to ignore it.

In some cases, you may even receive multiple verification codes back to back. 

However, WhatsApp may only send so many verification codes within a given period then afterwards, the app will lock you out if you log out.

This is exactly what the hacker wants, to lock you out of your account and they can do whatever they want with it within that time.

So, ignore those verification code messages if you did not ask to verify, and Do Not log out of your account, just continue using your WhatsApp account as you usually would.

  • Tap on the 3 vertical dots () on the top right then tap on Linked Devices.
  • A new window will open where you can see a list of all active devices, if you don’t recognize any of them, then chances are someone is hacking into your conversations and WhatsApp activities on your phone.

  • Select the device(s) you don’t recognize and Log out. Or just tap on the Log out of all computers option. This will stop the hacker from accessing your activities. 

However, this should be a caution for you to always check this option and log out of all devices when you are not using them.

Enable the WhatsApp two-step verification

With the two-step verification enabled on your account, any attempt to verify your phone number on WhatsApp must be accompanied by a six-digit PIN that you created using this feature.

So enabling this feature could come in handy in case you suspect a hack, or even as just a precautionary measure. 

To enable two-step verification:

Open WhatsApp and tap on the 3 vertical dots (), go to Settings > Account > Two-step verification > Enable.

Enter a 6-digit PIN code, then click Next

Tip: When this option is enabled, you can enter the email address that will allow WhatsApp to send you a link via email to disable two-step verification in case you ever forget your six-digit PIN.

Notify your contacts about your hacked WhatsApp

When someone compromises your WhatsApp account, they can easily be able to send messages to your contacts stating that the company sent a verification code and then they may gain access to their accounts too.

To prevent all this, send a message to your friends and family, letting them know that your account has been compromised, this prevents any further exploitation of your account and those of your contacts.

This may also prevent the hackers from using any of your contacts to attain information about you like banking details, email addresses, or any other personal information.

In extreme hacking cases, you might want to consider deleting your WhatsApp account completely to ensure that the hacker can’t use it.

Note that deleting your WhatsApp account and uninstalling your Whatsapp app are two different things. Uninstalling the app from your phone doesn’t delete your account.

To delete your account:

Go to your app and navigate to Settings > Account, then Delete Account

Deleting your account will erase all your messages and history, even your Google Drive backup. Also, you will be removed from all WhatsApp groups.
