ios – WhatsApp security code changes

I recently had to restore my iPhone as I wasn’t able to remember the passcode for it. Upon reinstalling WhatsApp on a group chat each of the members security codes have changed a number of times (3 times each) none of them have reinstalled Os/app or changed device. Can anyone shed some light on what could be the issue?

whatsapp messenger – Contact is showing weird name but shows propperly in Contacts

I noticed on whatsApp that my Moto Z4 Play is showing only for this contact a really strange name that doesn’t match at all with the contact name, I go to the Contacts App and try to edit it, but it is showing the rigth name. So… What could that be ?

How do you sort your chats by contact name in WhatsApp?

There doesn’t seem to be any way to sort them alphabetically in the chat list. If you click on the bottom right green button you can access the contacts list, and those contacts are sorted alphabetically. Currently the Whatsapp chat list is by chat date, meaning the most recent ones will come up.

Permanently turn off sound notifications on WhatsApp (macOS)

I often go to the settings of WhatsApp for macOS and turn off the audio notificaitons, but in a few days/weeks, they always come back:

Is there any way to keep this permanently off?

This seems like a bug for when, I assume, WhatsApp updates.

Generate whatsapp stickers from PC without any app

I am newbie when it comes to whatsapp stickers, and I don’t know about how stickers work.

But I am using a linux desktop where I have written a basic ruby script that could convert svg to webp, multithreaded. In a loop, it reads certain folders with svgs.

I have have 30 svgs in 4 folders, total 120 stickers. I want myself and people to add possibly a thousand more over time.

Currently I am used to copy the directory containing webp files to my android phone, use sticker.ly to manually select and generate stickers. That’s too much work.

I want my script to have the sticker generator code in the loop, where it will generate stickers from svgs, I can take the packs to my phone and add them to whatsapp. That way I will be saving a lot of time.
Is it possible?

Can WhatsApp, Signal or Telegram be hacked through a SIM SWAP attack?

In Cuba the telecoms/ ISP monopoly, Etecsa, works with the political police to spy on dissidents, journalists and others.
A common attack in Cuba is therefore SIM Swapping which is easy for them. It is also effective in order to eavesdrop on phone conversations and SMS.
My question is: Would the SIM Swap enable the attacker to also hack WhatsApp, Signal or Telegram and gain access to these messages or calls?
If so, are there any measures that can be taken to prevent the attacker from accessing the secure messaging apps via a SIM Swap attack?
Thank you very much for your help

applications – Can WhatsApp be used without granting contacts permission?

I’m trying to install WhatsApp, but I’m obviously uncomfortable about serving up my entire address book for Facebook to trawl through.

I’ve found plenty of posts from a few years back saying it is possible, but I’m wondering if something has changed.

On opening the app and going to the ‘chats’ screen, I’m greeted with a screen saying “To help you message friends and family on WhatsApp, allow WhatsApp access to your contacts” along with a link to open my settings.

If I push the green ‘chat’ button in the bottom right, I get a popup with the same message. If I hit the ‘not now’ option, it closes the popup and puts me back on the original screen.

There doesn’t seem to be a way forward here. Does this app just strong-arm you into uploading your contacts list in order to use it? Or is it potentially a more phone-specific issue?

WhatsApp groups on new phone

I upgraded to a new Android phone and plan to use WhatsApp on this phone with my old number. For the purposes of this question, I do not have my old phone with me, and do not have a chat backup (actually, my backup got corrupted somehow, long story, but let’s assume I don’t have access to any backup/history).

Now, this whatsapp account was part of several groups.

  1. Is there any way I can send a message to those groups? Since my number didn’t change, I should be still part of the groups but I don’t see any.
  2. If someone sends a message on that group, will I receive it on my new phone? (The same way I’d receive a DM from a single person who still has my old number)
  3. Some of these groups required admin permission to send messages, which I previously had. Would I need to ask for that permission again?

php – Passar variável através de LINK Whatsapp

Estou fazendo uma consulta no banco de dados. Essa consulta me trás 3(três) resultados. Porém, quando eu tento passar essa informação através do link do whatsapp ele só passa o último que o while realiza a busca. Como fazer para que o ele passe toda a informação exibida pelo Banco?

<?php
session_start();
header('Content-Type: text/html; charset=utf-8');
date_default_timezone_set('America/Sao_Paulo');
$conexao = new mysqli("xxxxxxx","cardapio_cheirinbao","d#m14e4E","cardapio_cheirinbao");

if(!$conexao){

  echo "Impossível se conectar ao banco de dados";
  exit;
} 

@$pedidoLokos = $_SESSION('numero_pedido');

$mensagem = $_GET('mensagem');

$consultaPedido = $conexao->query("SELECT * FROM carrinho WHERE NumeroPedido = '$mensagem'");
$numero = $consultaPedido->num_rows;
if($numero < 0):

    echo "Nenhum pedido realizado";
else:

        $valorTotal = 0;
    while ($exibePedido = $consultaPedido->fetch_assoc()) {
        $produtos = $exibePedido('produto');
        $valor    = $exibePedido('valor');
        $quant    = $exibePedido('quantidade'); 
        $valorTotal += $valor;
        ?>

<span><?php echo  "$produtos";?> <?php echo  "($quant) <BR>";?></span>

<?php 

header("Location: https://api.whatsapp.com/send?phone=5565993072186&text=$produtos");

    }

    echo "Valor total ".number_format($valorTotal, 2, ',', ' ');

endif;
