A well-liked and simple-to-use texting program is WhatsApp. It offers some security features, such as end-to-end encryption, that work to protect the privacy of your communication. With these strong security measures, WhatsApp is still susceptible to attacks that could compromise the confidentiality of your messages and contacts.

We can avoid compromising ourselves if we are only aware of our weaknesses because knowledge is half the battle. Here are a few methods for hacking WhatsApp in order to achieve that.

 How to Check My WhatsApp Hack or best 5 Way

Remote Code Execution via GIF

Security researcher Awakened discovered a WhatsApp flaw in October 2019 that allowed hackers to take control of the application using a GIF picture. When a user uses the Gallery view to share a media file, WhatsApp processes photographs in a certain way that is abused by the hack.

When this occurs, the software analyses the GIF to display a file preview. Because they include many coded frames, GIF files are unique. As a result, code may be hidden within the image.

A user's whole chat history may be stolen if a hacker sent them a malicious GIF. The users' chat history and the messages they sent would be visible to the hackers.

WhatsApp versions up to 2.19.230 on Android 8.1 and 9 were susceptible. Thankfully, Awakened responsibly disclosed the vulnerability, and Facebook, which owns WhatsApp, patched the problem. Keep WhatsApp updated at all times to protect yourself from this problem.

The Pegasus Voice Call Attack

The Rainbow voice call exploit was a further WhatsApp vulnerability identified in the first few months of 2019.

In this alarming exploit, hackers might gain access to a device by making a simple WhatsApp phone call to their victim. The attack might still be successful if the target didn't answer the call. And it's possible that the victim isn't even aware that malware has been put on their device.

This functioned using a technique called a buffer overflow. Here, a small buffer is intentionally overloaded with code during an attack in order to "overflow" and write code to a region it shouldn't be able to access. When a hacker has access to code in a place that ought to be secure, they might act maliciously.

Pegasus, an older and well-known spyware program, was installed as a result of this attack. Hackers were able to get information on phone calls, messages, pictures, and videos as a result. They could even use it to turn on cameras and microphones so they could record.

On Android, iOS, Windows 10 Mobile, and Tizen devices, this issue is present. The Israeli company NSO Group, which has been charged with spying on members of Amnesty International and other human rights activists, most recently employed it. As soon as word of the breach spread, WhatsApp was modified to fight off such an attack.

Socially Engineered Attacks

Socially engineered attacks, which take advantage of behavioral flaws in individuals to steal information or spread false information, are another way that WhatsApp is exposed.

One instance of this assault was made public by the security company Check Point Research, and it was dubbed FakesApp. This made it possible for users to modify the text of another user's reply and abuse the group chat's quote feature. In effect, hackers might insert false statements that seem to be made by other trustworthy users.

The researchers were able to achieve this by decrypting WhatsApp messages. They were able to view data communicated between WhatsApp's mobile app and website because of this.

On operating systems like iOS 8 and higher, applications can access files in a "shared container."

Media File Jacking

Telegram and WhatsApp are both affected by media file jacking. This exploit makes use of the way media assets, such as images or movies, are received by apps to write those files to the device's external storage.

The malware is first installed as part of the attack inside an app that first appears to be secure. 

Following that, Telegram or WhatsApp can monitor incoming files.. The malware could replace the original file with a phony one when a new file is received

The issue's discoverer Kaspersky thinks it might be used to deceive people or spread false information.

Facebook Could Spy on WhatsApp Chats

Gregorio Zanon, a developer, believes that this is not strictly accurate. While WhatsApp uses end-to-end encryption, not all communications remain private despite this.On operating systems like iOS 8 and higher, applications can access files in a "shared container."

The WhatsApp and Facebook applications share the same device container. Additionally, while chats are encrypted when they are sent, they may not always be encrypted on the device from which they originated. This indicates that the Facebook app might be able to steal data from WhatsApp.

To be clear, there is no proof that Facebook has viewed private WhatsApp messages using shared containers. However, opportunities exist. Even with end-to-end encryption, Facebook's all-encompassing net may still be able to access your messages
