WhatsApp: the trick to know the location of a contact without sending it to you

Is it possible to know exactly where a user is without sending the location? The answer is yes, but it is not that simple. To do so, it is necessary to enter a series of codes in WhatsApp, something that is recommended to be done from the computer and not from the cell phone.

To get started, you need to have a large number of programs installed. Then it must log in to WhatsApp Web and let it run in the background. Key fact: you do not have to do it from the app that is downloaded in Windows 10.

Subsequently, a series of simple steps must be executed that will allow knowing the exact location, but not in real time.

How to see a contact’s location without them sending it

These are the steps to know the location of a contact without sending it

Here are the steps to know the location:

  • Press Ctrl + Alt + Delete on your keyboard to open the task manager. If you are logged out, don’t worry.
  • Press Win + R to open the run function and then type ‘cmd’ in the field and hit enter.
  • A command prompt will appear, where you will have to type ‘netstat-an’ and then hit Enter. Then the IP address of the other person will appear.
  • Go to the page http://www.ip-adress.com/ip_tracer/ , put the address that came out and immediately a nearby location of that person will appear.

WhatsApp, is it safe?: This is how its encryption works

WhatsApp is the application of chat most widely used in the world and easily outperforms rivals such as Messenger, Signal and Telegram. Given the amount of sensitive data that we usually share in online conversations, is it safe the application?

Also, should you be worried about possible attacks or data leakseven with the encryption What WhatsApp claims to offer? Here we answer those questions with a closer look at the security measures of WhatsApp, including end-to-end encryption.

We also discuss some additional features you can take advantage of to keep your chats safe from prying eyes.

WhatsApp security: what is end-to-end encryption?

Instant messaging has existed for many years on the Internet, but the first implementations were far from safe. On the one hand, messages were exchanged between users in plain text.

This meant that anyone with access to the company’s servers could read your messagesincluding intermediaries or malicious actors.

And while many services implemented the encryption in the late 2000s, companies generally had the keys to decrypt user communications.

However, more recently, many platforms have adopted the end to end encryption (E2EE) to improve the confidentiality of messages and the Privacy of the user.

In an end-to-end encrypted communication channel, only sender and receiver they have the necessary keys to decipher each other’s messages.

No one else, including the Platform, your Internet Service Provider (ISPacronym in English) or even a hacker with access to the encrypted data, can read your messages.

Signal’s role in WhatsApp security

whatsapp uses end to end encryption for all messages and calls by default. Since 2014, WhatsApp’s end-to-end encryption system is based on the signal-protocol open source Open Whisper Systems.

You may know the company as the chat app developers Signala WhatsApp competitor that prides itself on putting security and privacy.

According to the WhatsApp documentation, all your communications on the platform are protected with end to end encryption. This includes messages, media, voice memos, calls, and even status updates.

The content of your WhatsApp chats is kept confidential.

How does WhatsApp encryption work?

The Signal encryption protocol used by WhatsApp combines multiple cryptographic techniquesstarting with public key encryption.

In short, it implies that each user has a randomly generated key pairone that remains private and another that is distributed publicly.

The idea here is that a sender uses the public key of the recipient for code the messages. On the other hand, the recipient uses his key private to figure it out. Since your device generates the private keyWhatsApp never has access to it.

This simple cryptographic technique has been used for decades, with modified versions securing everything from emails to cryptocurrency wallets.

The Signal protocol used by WhatsApp is universally considered to be the gold standard for encrypted messaging.

While your chats will never be intercepted on their way to you, they are quite exposed once they reach their destination.

Double ratchet encryption

However, standard public key encryption is not secure enough on its own. suffer from a single failure point. If your private key is ever compromised, an attacker could decrypt your past, present, and future chats without any control.

To remedy this, the developers behind the Signal protocol devised a novel technique called double-ratchet encryption.

Instead of using a static set of keys for each user, the protocol uses a combination of permanent and temporary keys. The latter changes every time you send a new message.

This means that if a theoretical attacker were to gain access to a particular key, they would not be able to crack more than a few few messages.

Constantly renew the keys seems like an overkill solution, but it’s also simple enough that our smart phones They can handle it effortlessly.

Of course, there is much more to the encryption system of WhatsApp, which you can find in the company’s technical document on the subject.

However, the crux of the matter is that encryption is strong and robust enough to protect you from listening and similar basic attacks.

Your phone and any recipient's device are much easier targets for potential attacks.

private encrypted WhatsApp chat

WhatsApp allows you to verify that your chats and individual calls are end to end encrypted. To do this, open a chat within the app, tap on the contact’s name, and finally tap on the “encryption“.

you will meet a QR code and a 60-digit number. Now, follow the same steps on the recipient’s phone and compare the values. As long as the number matches on both devices, your chat is properly encrypted end-to-end.

WhatsApp calls this a “security code“, but it’s just an easier way to represent the public key mentioned above. Completing this step also helps ensure that your communication reaches the right person and not a malicious imposter pretending to be your contact.

It also holds WhatsApp accountable: if the keys don’t match, it would put the company under tremendous scrutiny. The function of check of the WhatsApp password allows you to make sure that your chat has not been hijacked or intercepted by a third party malicious.

If you lose your phone, an attacker with physical access could copy your WhatsApp message database from the device.

This is what WhatsApp knows about you

Despite these services encryptionWhatsApp records a good amount of information about you outside the chat interface. The data collected includes your contact list, location, device identifiers, and transaction history, among others.

Signal is the only alternative that claims to collect less data and emphasizes the security with security audits independent. Other popular chat apps like Messenger and Telegram they don’t even offer end-to-end encryption by default.

Is WhatsApp really secure?

It is already clear that the content of your WhatsApp chats is maintained confidential. However, there are still some potential dangers security that you must take into account.

While your chats will never be intercepted on their way to you, they are quite exposed once they reach their destination. In other words, your phone and any recipient’s device they are much easier targets for possible attacks.

If you lose your smartphone, for example, an attacker with physical access I could copy your message database WhatsApp of the device. WhatsApp encrypts this file and key recovery requires root access on Android.

If you don’t know what that is, you probably have nothing to worry about. That said, they would still be able to access media files like images and videos. All of this can be easily remedied with a simple screen lock on your smartphone.

Messenger and Telegram don't even offer end-to-end encryption by default.

Be careful with WhatsApp backups

Your phone and cloud storage account are easier targets for most attackers, so make sure your backups are good.

Another much publicized potential attack vector involves cloud backups in Google Drive and iCloud. By default, WhatsApp will back up your chats on these services without any encryption.

This means that if an attacker somehow gains access to your storage account in the cloud, theoretically you could also get your whatsapp data.

WhatsApp implemented the ability to encrypt chat backups with a password or encryption key. The latter is a randomly generated 64-digit key.

You can store it in a password manager for maximum security. This is an optional feature, so make sure you enable it in Settings > Chats > Chat backup within the WhatsApp app on Android.

WhatsApp allows you to verify that your individual chats and calls are end-to-end encrypted.

Two-factor authentication in WhatsApp

As for the security features optional WhatsApp, consider also activating the two factor authentication. You can find it in WhatsApp Settings > Account > Two-Step Verification.

This will require you to enter a PIN when you register your account on a new phone. Will not prevent leaks databut could prevent login attempts fraudulent by malicious actors.
