According to some security reports published by (Checkpoint) the specialized company in discovering security flaws in Whatsapp, the application includes a very dangerous flaw that allows hackers to change the content of the messages.

Apparently  Whatsapp is already aware of this flaw, but they didn’t take a step towards solving this problem so far. According to what was mentioned by Checkpoint, this flaw gives the hackers three ways to exploit it.

The first way  depends on changing the sender’s identity, the second one is the way that allows hackers to change the content of the messages in addition to the third one that has been solved by Whatsapp that can make the user believe that he sent a private message in a chat group while everybody else can see the message.
