I doubt is the same file, but it surely uses the same principle. To be viewed properly, the file must comply with a file specification, that defines what kind of data is expected on which field, constraints on those values and things like that. Libraries to parse the files will use the specification to know how to parse the files. But sometimes files get corrupted, accidentally or on purpose. And when a corruption occurs, it can change a field to something that does not make sense, but the library loading the file tries to use that value anyway, usually writing garbage to memory, or reading garbage from the file. That leads to memory corruption, ending on a program error or code execution. If Whatsapp currently suffers from this "attack," it's because a library used to parse GIF files is not dealing with corrupt files as expected. That can lead to remote code execution, and is generally considered a serious flaw.

First, a note of caution: Unless you securely receive and verify the user's public key ("Security Number" or whatever WhatsApp calls it), WhatsApp is no more secure against spoofing than normal SMS is (because normal SMS is the only way it authenticates users). If you're trying to avoid using SMS because it's expensive, then WhatsApp is a reasonable alternative; just don't think that it's dramatically more secure than SMS. It is arguably more secure in that it's encrypted end-to-end, so it can't be intercepted en route, which is a significant risk with SMS. However, it's also more likely than SMS to be routed to multiple devices (one if which might have been stolen or shoulder-surfed), and/or for a user to still have a WhatsApp number that is no longer their phone number (in which case the WhatsApp account could be stolen from under them at any time). If you want to add some extra degree of security, your WhatsApp client could record the user's public key when they set up the WhatsApp auth factor. That way, if something happens to their WhatsApp account, you'll know because the public key will change. To actually answer your question: it's arguably better to use the QR code, since that can be sent through an already-authenticated channel (the HTTPS connection to your front-end, presumably a webpage), and then let the user respond from an account that they trust. Simply sending the code to a number has a small risk that it's not a number the user controls any more (maybe they recently changed numbers and gave you the new one, but hadn't updated their WhatsApp account yet, and somebody else had gotten the old number and set up WhatsApp to route that number to them). There's also a small risk that the user just made a typo entering their phone (WhatsApp) number. In either case, you risk sending the second-factor code to the wrong person, who - if they can guess the legit user's password - could then log in as the user. Otherwise, though, it doesn't matter. Most likely you'll answer this question for other reasons (cost and user experience) rather than security. That's especially true if you expect your users to rely on WhatsApp enough that there's almost no risk they'd make the mistake described above (though note: people get their email address wrong all the time; getting a phone number wrong is pretty easy). While you're at it, consider adding support for https://webauthn.guide/ (see libraries https://webauthn.io/ ), which can use either hardware tokens (e.g. Yubikey, Titan Key) or platform security (OS login methods such as FaceID, TouchID, Windows Hello, Android's fingerprint scanner, PIN, etc.) to securely perform public-key-based authentication. WebAuthn can be used as either a second factor or as the only factor, and is the only authentication system I'm aware of to provide really strong anti-phishing protection (the public key is unique per site; even if the user doesn't realize they're on the wrong site, their browser will send a different public key). It's also often more convenient than OTPs or TOTP (e.g. Google Authenticator).

If you don't know the sender of the videos, I personally would not open anything. You could theoretically open the videos in an isolated environment where the impact if it is harmful is lower, but I would not open it on any device, in any environment where it could do serious damage. With that said, fight your curiosity!

In theory, yes, the app could do whatever it wants with the files. You may need to check the terms and conditions for whatever app to see what usage you have explicitly agreed to. In general, you have to trust the app and its vendor to not abuse their access or become compromised. This is true for installing any software on any system.

Whatsapp allows a letter only if the number is in contact. Uri uri = Uri.parse("smsto:" + "9211889055"); Intent i = new Intent(Intent.ACTION_SENDTO, uri); i.setPackage("com.whatsapp"); startActivity(Intent.createChooser(i, "")); On Facebookeng messer, I realized that I needed to know the user on the facebook. But this id can be found through API or offer users to throw them out of their pages. Uri uri = Uri.parse("fb-messenger://user/"); uri = ContentUris.withAppendedId(uri,100001899606015L); Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent); The attachments of the Contact and the FB for the Android, I understand, do not allow the addressee to be contacted without using my API.Correct me if I'm wrong... ♪

Of course you'll be able to carry out the shipment.It's only before you have to go through the sponsorship:First thing to do is get Token and QR a picture (in fact, you will emulate the work of webwhatsapp).Then, from the mobile device, scan this code and receive callback from whatsapp on successful copying and token.You'll be able to send messages to the simple Post Request.Party services do the same job, just for you.Just send a message without copying.P.S. Many of the data will have to be collected from JavaScript, because you're just asking, you won't get much information, which complicates the emotion process.

Decision$(document).ready(function() { // Отправить запрос при нажатии на кнопку $(".button").click(function() { $.ajax('https://eu43.chat-api.com/instance**********/message?token=**********', { data: JSON.stringify({ phone: $('input[name="recipient"]').val(), body: `Имя: ${$('input[name="name"]').val()}\n`+ `Телефон: ${$('input[name="phone"]').val()}\n`+ `Адрес: ${$('input[name="address"]').val()}\n`+ `Заказ: Pizza " Margarita"` }), contentType: 'application/json', type: 'POST' }); }); });

You should use Intent.ACTION_SEND_MULTIPLE instead of Intent.ACTION_SEND.Intent intent = new Intent(); intent.setAction(Intent.ACTION_SEND_MULTIPLE); intent.putExtra(Intent.EXTRA_SUBJECT, "Here are some files."); intent.setType("image/jpeg"); /* This example is sharing jpeg images. */ ArrayList<Uri> files = new ArrayList<Uri>(); for(String path : filesToSend /* список отправляемых файлов */) { File file = new File(path); Uri uri = Uri.fromFile(file); files.add(uri); } intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, files); startActivity(intent); It may be easier, but I left a few lines to break every step you need.Starting with API 24, the sharing of URI files will cause the exception of FileUriExposedException. To fix this, you can use URI content with FileProvider.

I figured it was about oauth. It's not a protocol, but it's not hard to do this through api where data on the user can be downloaded. We're making a reference to wa.me/{Number of your botto account}?text= {Any entrance identifier looking like a welcome message} as soon as we get a message to the beans, we're safely corroborating the person who writes his greetings and either offering a link to return to the site or the site itself tracking the status of authorization. I've done this through ChatAPI on three projects, since all the messages coming in, they haven't encountered any bananas. You can try it through the official API, but I didn't work with it.

Yeah, maybe. Wozapp has an official IPA. Just like the telegram, bot can't start first. The user should start a dialogue. In this case, you get a 24-hour, free window of contact with the client. However, it is not possible to connect directly to the octopus of IPAs, but only through https://www.facebook.com/business/partner-directory/search?platforms=whatsapp&solution_type=messaging&sort_by=alpha ♪ Each partner collects tariffs for sent messages.

It's likely that API only has a fee, and you can always easily check on their official website. That's the reference to them. https://www.whatsapp.com/business/api You can see.

You're interested in working with the Native API. In Xamarin it is done through I have https://github.com/tripolskypetr/NearestMetro GitHub, where I'm on the same tour of the last location. The original code of this decision may be useful.

You don't have all the references to "#top_nav a" because of that code at the end of the page. + jquery.js should be connected to bootstrap.js <script> $(document).ready(function(){ $("#top_nav").on("click","a", function (event) { //отменяем стандартную обработку нажатия по ссылке event.preventDefault(); //забираем идентификатор бока с атрибута href var id = $(this).attr('href'), //узнаем высоту от начала страницы до блока на который ссылается якорь top = $(id).offset().top; //анимируем переход на расстояние - top за 1500 мс $('body,html').animate({scrollTop: top}, 500); }); }); </script> The solution is to put references in that menu (except tel and whatsapp) of any non-existent class, such as MyClass, and correct$("#top_nav a.MyClass").on("click", function (event) {

Of course, what you can't do is talk about the limited API you worked with. If you write, and what you didn't do, I'd probably be able to answer more detail, and that's how you worked with the API and what tasks you were facing.Well, official WhatsApp API know exactly how to write integration on C#. It's easier to connect the official API, but it's still harder and more expensive than working with gray API, for example.Most informal API have SDK generators in different languages, including C#.

Skype doesn't reveal how he works. Or Microsoft doesn't open it. For as long as I know, they have their own protocol.Only registered and authorised users can make calls in the skip.You can do all the right webRTC.

chat-api from mgp 25 is outdated because the security system has changed in whatasapp. chat-api.com uses web api, rather than docker + python + selenium. I mean, it's the emulation of the launched web-based Watsap on the server where you can send and receive messages, i.e. all via the IPA are going through JSON.

It's possible. Watch the documentation. https://faq.whatsapp.com/en/android/26000030/?category=5245251 Actually, your request now looks like a fl.ru.I was in a mood after reading:and there once.

Yes, you can, but it doesn't require API to use the standard mechanism. Intentapproximately:PackageManager pm=getPackageManager(); Intent intent = new Intent(Intent.ACTION_SEND); intent.setType("text/plain"); String text = "Текст сообщения"; //задаем получателя String telNumber="+7916****123"; intent.putExtra("jid", telNumber+"@s.whatsapp.net"); PackageInfo info=pm.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA); //проверяем есть ли Whatsapp (может выкинуть Exception если нет whatsapp) intent.setPackage("com.whatsapp"); intent.putExtra(Intent.EXTRA_TEXT, text); startActivity(Intent.createChooser(intent, "Share with")); Details https://faq.whatsapp.com/en/android/28000012

You understand correctly, not everything available in URI is the object of a file system. In your case, the name of the resource can try to extract in such a way as:Cursor cursor = ctx.getContentResolver().query(contentUri, null, null, null, null); if (cursor != null) { // if null, uri cannot be resolved int nameIndex = cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME); cursor.moveToFirst(); String fileName = cursor.getString(nameIndex); cursor.close(); } Of course, there's no expansion of the speech.This could help. MIME type: mimeType = ctx.getContentResolver().getType(contentUri);
