How to Know If Your WhatsApp is hacked

by Jenefey Aaron   Updated on 2020-09-04 / Update for  WhatsApp

Your cell phone holds a lot of valuable information. Which means if someone wanted to know anything about you, all they'd have to do is hack one your accounts. WhatsApp users in particular have a lot to worry about since the service can hold a lot of information including phone numbers, photos, videos and all the messages you send to your friends. Yet, we all know that WhatsApp is encrypted, which begs the question; can WhatsApp be hacked?

The truth is, WhatsApp can be hacked, but the hacker would need special apps and access to your device to hack your WhatsApp account. One of the best ways someone can gain access to your WhatsApp account is by installing spy software on your device. But these spy apps often leave a signature that can help you detect the presence of these apps. These symptoms include the following;

1. Your Device Behaves Badly

Is your device suddenly displaying odd behavior? For example, does the device suddenly light up for no reason or shut down unexpectedly? Does it make random beeping noises even when there is no incoming notification? This odd behavior can be indicative of the presence of spy software on your device.

2. Sudden Battery Drain

Some spy apps can significantly use your battery power causing a sudden drop in your battery life. If you notice that you have to constantly charge your battery even when you rarely use the device, it is possible that there is a hidden app on the device. These tracking apps often use location services to track the device and Wi-Fi to send information about the device to the hacker and therefore consume a lot of battery power.

3. Background Noise

Another way to know if your WhatsApp is hacked is when you hear background noise when making or receiving a phone call. The reason for this is because the spy apps that are installed to monitor you WhatsApp can also be used to monitor other data on your device including phone calls and messages. One of the ways someone can monitor your phone calls is by recording them and the action of recording the phone calls can result in a weird background noise. This noise can sound like static, clicking or beeping and although it can be indicative of a bad connection, you should be wary when you hear it too often.

4. Increased Date Usage

Like we mentioned before, most of the Spy apps that are installed to track or hack a device will often use your data connection to relay information to the person tracking the device. This means that they will use your data or Wi-Fi connection. Therefore, if you suspect that your WhatsApp has been hacked, the best way to determine for sure is to check the data usage. On Android devices, you can find this information in the My Data Manager section of the device settings. On the iPhone, find the Data Usage settings in the device settings.

Only one of the signs above don't necessarily mean that your device has been hacked, but seeing at least two or three may be a sign that someone is spying on your device.

How to Prevent Someone Hacking Your WhatsApp

There are some measures you can take to prevent someone from hacking your WhatsApp. They include the following;

  • Avoid leaving your phone unattended. Someone may take the chance to install a spy app on your device.
  • Use a strong lock code, pattern or access PIN to keep the device secure.
  • Install anti-virus software that will locate and remove all spy apps from your device.
  • Avoid using public Wi-Fi since hackers can use the public connection to gain access to your device
  • Don't open emails, messages and WhatsApp messages from contacts you don't know or that contain strange information.
