Free instant messaging apps can be harmful. In fact, they can encourage hackers to take control of your mobile to read your private messages. When you install them on your smartphone, these applications have access to all your personal information and data. Malware can be hidden in these free apps to steal your data. This often affects instant messaging applications which are very popular all over the world.
Find out which are these free applications that could be harmful to your smartphone and how to protect yourself from them.
What are the free applications that could be harmful on your smartphone?
These instant messaging apps are very popular among smartphone users. They allow you to communicate with your loved ones around the world. They are usually protected with end-to-end encryption. This security system allows WhatsApp, Signal or Telegram users to ensure the protection of their conversations. Anything shared during exchanges on these free apps is inaccessible to people who don’t join the conversation. However, there are hackers who can integrate malware into your free applications to take control of your mobile and steal your personal data.
Apps like iKeyMonitor or Lost Android can be used to read your text messages or conversations on social networks like WhatsApp. These are monitoring applications often downloaded to integrate parental controls on their children’s cell phones.. Often installed by parents, these apps can track text messages, calls, websites, Facebook, and instant messaging apps like WhatsApp. They can therefore also be used by hackers. Messaging apps like Signal, Telegram and WhatsApp have end-to-end encryption and messages are normally secure. However, they could also be hacked and your conversations exposed. The hacker tricks SS7 (a set of telephone signaling protocols, this is the main network for linking telephone networks together) to have the same user number as an account. He can then install instant messaging applications and receive the secret code to have full control over the account to be hacked.
The cybercriminal can then recover your data and conversations by impersonating you.
What to do if your smartphone has been hacked?
Cybercriminals use harmless free apps to embed malware on your smartphone. They can interfere with your cell phone to retrieve your personal information or even steal your bank details. To deal with this hack, you need to uninstall all the apps you don’t use on your smartphone. All suspicious apps on your device should be removed to protect your data. Then, change all the passwords for your main accounts. For example, your Google or Apple account or your social networks and your online bank.
Finally, you can also install antivirus software on your smartphone to secure your device and protect your personal data.
