Hack WhatsApp without QR code

WhatsApp flaw lets users modify group chats to spread fake news. As it is widely known, WhatsApp is a popular messaging app with billions of users worldwide. However, recently it has been found that the app is vulnerable to hacking attacks. Hackers have found an efficient way to intercept and then modify messages according to their will. This can be done not only in private communication between two users but also in group chats.


The security issue has been found by CheckPoint, which is a security company from Israel. They have found a loophole in the security protocols of WhatsApp which allows hackers to gain control over the messages and modify them as they wish. This is ideal for spreading false information and fake news.

Where is the problem found?

The security problem is in the connection between WhatsApp mobile app and the WhatsApp Web. The protobuf2 protocol is used for decrypting the encrypted messages, which allows the hackers to take advantage of the ‘quote’ feature of the group chat in WhatsApp and hack WhatsApp chat without victim’s phone.

They can then change all kinds of information – from the name of the sender and content of the messages to the previous private messages sent to individuals from the WhatsApp group.

An interesting thing that should be mentioned is that this vulnerability in WhatsApp cannot be exploited by a third party outside the group users. It can only be used by malicious group members who intercept and decrypt messages for their own reasons.


How hacking WhatsApp messages is done?

This vulnerability in WhatsApp is exploited relatively easily by malicious WhatsApp Users. Israeli CheckPoint researchers have put it to the test and tried to intercept and modify messages by creating a custom app extension.

With the help of this tool, researchers (and hackers) first need to input public and private keys. These are obtained very easy from WhatsApp Web before the specific code is generated.

After that, all WhatsApp communication can be decrypted and manipulated. The researchers have found out three attacking techniques with which the WhatsApp messages can be intercepted and modified. They are the following.

The first attack is by changing the reply of the WhatsApp correspondent in order to put different words in their mouth. By using the specifically created extension for that (Burp Suite extension), malicious users can completely change the message reply sent by someone in the WhatsApp group. This essentially means putting words in their mouth or claiming that they have said something they did not.


The second attack is by changing the sender’s identity in the WhatsApp group chat, even if the specific person is not a group member. With this attack, the hacker exploits the vulnerable ‘quote’ feature in the app which lets WhatsApp users reply to an older message through tagging it.

Then malicious users can impersonate someone else or someone who is not a group member in order to spoof a reply message.

Finally, the third attack happens when a private message is sent to an individual group member, but when the recipient of the message replies to it, the whole group can see the contents of it.

With this attack, the malicious user can send a specially designed message to a specific group member. That message is only seen by that individual, but if he chooses to reply then the message can be seen by everybody in the WhatsApp group.

The best way to hack WhatsApp overall

With that all being said, we can conclude that WhatsApp hack is definitely possible today. Just a reminder that if you are interested in hacking someone’s phone and read their WhatsApp messages, you should do that only if the other person has given you their consent for doing that. Otherwise, you may be violating their privacy and are risking legal repercussions.


In general, iOs or Android spy app is recommended for concerned parents that want to monitor the online activity of their underage children. Truth is that NEXSPY is an excellent software that does not require any special computer skills for you to use, so it is a pretty good option for beginners.
