How do I know if my WhatsApp was hacked or tampered with?
In addition to spying on your activity at WhatsApp, it is also perfectly possible for someone to spy on your conversations.
Even if they hack into or interfere with your communication for this application. But fortunately there are ways to know if this has happened and there is a solution.

Spying basically means someone might be watching your WhatsApp. Generally, it has been cloned or opened on another device, and this is quite simple to do.
A hack or intervention requires vulnerating the security of the application to see your messages or manipulate them, something complex and very difficult to happen if you are a "conventional" person and do nothing illegal.
How do I know if they're spying on my WhatsApp?
Notice that WhatsApp is open on another device (Windows 10 in this case)
If someone is very interested in your life and took advantage of an oversight of yours, chances are you are spying on WhatsApp Web. He probably took your cell phone temporarily and in just a few seconds connected your WhatsApp account to a PC (or even another cell phone), through the WhatsApp Web functionality.
By doing so, that person will have a "duplicate" or "clone" of your account on that other device. He'll be seeing your WhatsApp messages on that computer (and he'll even be able to answer them), even if the cell phone is already in your possession.
In this way you are spying on a person's WhatsApp from a computer.
The WhatsApp on your cell phone will function normally and as usual. However, everything you send and receive will be reflected in that other device.
What do I do if I'm being spied on by WhatsApp Web?
If you see a notification as in the image above, alert. That means your WhatsApp is cloned the way it was before. If it wasn't you who did it, they're definitely spying on you and watching your messages.
Fortunately, the solution is simple. Simply tap on that notification and on the next screen tap "Close All Sessions". This way the spy will immediately lose access to your account.
To prevent this from happening to you again, set the screen lock on your phone. That way, even if someone picks up your phone, they won't be able to access the WhatsApp application to connect it to another device via WhatsApp Web. You can also block access to the application.
How to tell if my WhatsApp is open on another device
Another way WhatsApp might spy on you is by activating the account on another device. Basically, they register your WhatsApp number in another mobile and during its configuration, they recover all your chats or conversations saved in the application. Someone can do this by taking your cell phone or SIM card for a moment. Just receive the verification code, and with it you can see your WhatsApp on another computer.
In this case it is very easy to know if you are being spied on by the WhatsApp. Your cell phone will show that this phone could not be verified because your phone number has been registered on another device.
The obvious solution is to use the "Verify" button to take control of the account again.
There is a sophisticated way offered by WhatsApp to prevent this from happening again. This is the two-step check system. When you try to activate your WhatsApp on another device, you will be asked for a security code that only you will know. Without that code it will be impossible for someone else to register your WhatsApp on another computer.
How do I know if my WhatsApp was hacked?
Watch as the hacker alters the victim's message, using a quoted message.
As we said at the beginning, it's pretty unlikely your WhatsApp is hacked. However, it is not too much for you to know some interesting things about this subject.
For example, in the event that a conversation becomes strange. An attacker might use the "Reply" or "Quote" option to alter the text of your messages.
This is possible either in private chats or even in groups, something that can be used to misinform or confuse members. However, it is very unlikely that this bug will be exploited by anyone, which is why WhatsApp has said it won't fix it.
As a preventive measure, it is important that you do not expose your WhatsApp number publicly. Previously you could hack and spy on your chats just by answering a video call.
If you suspect you've been hacked into the WhatsApp, there are a couple of things the experts advise you to do. For example, reinstall the application to generate a new record that forces other devices to close sessions.
You can also request the temporary deactivation of your account at support@whatsapp.com, claiming loss or theft of your device. You can reactivate your account up to 30 days later.
How do I know if my WhatsApp is bugged?
This green warning means that the connection is secure. It is impossible for the communication in WhatsApp with that contact to be intercepted.
WhatsApp ensures your communication with each contact, with a code or key. As long as they're both handling the same code or key, you can rest easy. As WhatsApp indicates, no one is intercepting your messages or calls with that contact. Your WhatsApp is NOT intervened.
Both people can verify on the conversation screen that they have the same code. In the menu (top right), select "View contact". Finally play on "Encrypted". The numbers you see there must be the same on both phones.
WhatsApp alerts you when a contact's security code has changed.
If your security code is different from your contact's, your connection is presumably not entirely secure and could be tapped. This can happen if the contact reinstalled WhatsApp or changed phones (WhatsApp alerts with a notification if this happens). To fix this, send a message to the contact.
This should force the reconfiguration of the same code for both. Verify that it is.
Leaving aside spies or hackers, authorities can also intervene in people's WhatsApp to detect terrorism and illegal activities such as drug trafficking.
For example, in Germany, police use Trojans to remotely obtain chats from WhatsApp or other device information. Even evading the WhatsApp security mentioned above.
Spy applications
Uninstall any application that threatens your data or privacy
For security reasons, it is not too much to scan your cell phone for potentially spy applications that you may have installed. If there is one, uninstall it (unless it has a purpose for you, such as Cerberus, which serves to track the cell phone in case of theft).
A good tool to perform this task is MalwareBytes. After scanning the phone, uninstall it to avoid performance problems or slowness. You can also use one of the antivirus programs we recommend.
Safe alternative to WhatsApp
According to experts, Signal is the most secure messaging application available today. Not only because of the security it offers for communication, but also because of the minimal amount of information it keeps about its users.
