Typically, these messages are designed to lure unsuspecting contacts of the infected user into downloading the malware and allowing it to execute and run on their own devices. This in turn then spreads the reach of the malware, which will then continue to use WhatsApp for distribution and propagation.
The malware will lure the user into accepting multiple permissions that the malware then uses to its advantage. The malware, on installation, requires specific permissions to be enabled before it can conduct its malicious activities. The malware will display instructions to manually enable them when launched if they are not already present on the newly infected device.
The malware will intercept all incoming notifications relating to WhatsApp, and attempt to reply to incoming messages itself with a phishing link to entice the sender into downloading the malware so the distribution/propagation cycle can continue.
As the alert below shows, this may reduce battery life on the device but is abused by the malware as a further persistence mechanism to prevent it from being killed, even if it remains largely idle for extended periods of time:
The malware will now attempt to reach out to its C2 at hxxps://netflixwatch[.]site/settings[.]php. (NOTE: this C2 has since gone offline after the Google Play store was alerted that this was a fake app and the app was removed from the store.)
The malware will attempt its distributed propagation by listening to all notifications related to WhatsApp. If a message is received via the INBOX, the malware will attempt to generate a reply and send that response containing the malicious applications download page:
After the device receives a WhatsApp notification and that message has been intercepted by the malware, it will attempt to craft a reply. The malware will utilize information it received from its C2 before sending the reply. This response typically lures a user into clicking the phishing link.
At the time of writing, known files relating to this malware are not currently hosted on the Google Play store; however, they were initially hosted on the APK distribution platform before removal.
The Google Play store is the official digital distribution service run by Google to host Android APK files. Though the service is well maintained by Google and has strict security protocols in place, this does not mean the Google Play store is impenetrable, as malware can very occasionally bypass controls and reside there.
Android malware can hide in a number of places. Typically, Android malware can be hosted and distributed via third-party hosting websites relating to Android applications, as these tend to have less reputable and efficient security checking.
The malware will attempt to cancel all incoming WhatsApp notifications to hide its actions from the user. The malware will then automatically craft a response to the sender of the message and 'reply' with a brief message and a link to download the malware.

I am designing a Netflix Application for BlackBerry mobile devices. I am currently working on the OAuth. I am at the point where I can generate a Netflix login page in an embedded browser field in my application.
After the user signs in, Netflix will send the user from the login page to a specified callback url. The callback url will also contain an authorized token, which is then needed to send back to Netflix.
My question is: How am I supposed to do this on a mobile device? Is there a procedure set in place? I am unsure how I can extract the authorized token from the callback URL and send it back to my application. From my research, it does not appear that Netflix will provide a PIN/verifier for the user to then type into the application...
There are two ways to deal with callbacks on mobile devices. The first is to set the value of oauth_callback to 'oob'. This is done if your device is unable to receive callbacks. See the OAuth spec, section 2.1:
The second way, if your device supports it, is to use a custom URI scheme. I know that on iPhones, you can register a callback with a custom scheme that is assigned to your application. Is there a way to do this on a BlackBerry? If so, I'd use this approach as it's a much better user experience.
Instead of embedding browserfield, you may be better off creating a seamless (i.e. browserless) user experience by simply letting the mobile app do all the necessary handshaking with netflix. You'll need to set up a public domain server as your callback host for OAuth and have that negotiate your new session key/secret key and pass it back to your device.All the while, the device will need to maintain an open http connection to your public server in order to finally receive the credentials and proceed to request the user data directly from netflix.The whole round trip should not take more than roughly 15 seconds so HTTP timeouts should not be an issue.You'll need to first study(i.e. "screen scrape") the netflix login html page to extract the necessary/relevant html form param names etc. Good luck.
If you launch Netflix on your phone (iOS or Android) you can cast to your Chromecast (or Roku). The content from Netflix is now playing on your TV. But here's the thing. Some people think that your phone is actually doing the streaming, and transferring the output to the TV via the Chromecast (or Roku). But it's not. What's actually happening is that when you started "casting" the Chromecast (or Roku) opened its own Netflix app, took the information about what was playing, launched that content, then moved to whatever timestamp your phone was on. All that really quickly. But the key piece is that your phone is no longer doing the streaming, the Chromecast (or Roku) is.
The connection between the phone and streamer can be used to FF, RW, Pause, Play/Resume the stream, but it's still the streamer, not the phone, doing the actual streaming. Chromecast has the apps already loaded, or if not, can load them quickly without intervention. However, if you remove Netflix from your Roku, then try to "cast" Netflix from your Roku, you'll see Roku prompt you to download Netflix.
Then there's this other thing that's commonly called casting. Remember I said your Chrome browser? Well, it's got a "cast" button or link. Click that and your browser tab contents appear on your Chromecast (or Roku, you can select where if you have more than one on your network). In that instance, your browser is actually doing the heavy lifting. It's really mirroring the tab to the device.
You didn't ask this, but don't Miracast. Well, actually go ahead, but be prepared to be disappointed. It may work great, but it may not. Roku does support it, but the other device, Windows or Android-based phone (or Blackberry?) may or may not support it. As I said, Android doesn't support it, but some phone manufacturers put in the stuff to work apart from Android. So, kludged together. If it fails, it fails.
I have a 4th generation Apple TV HD. I have no issues except with the Netflix app. I have a rather lengthy "My List" and ever since they deployed their ribbon interface I've had issues. After I've watched a video and return to the list, the longer I scroll, the scrolling begins to slow down. Over time, it slows so much that the app becomes unresponsive.
I contacted Netflix and after going through the usual motions, restart this and restart that, and explaining I'd done all this and that and telling them this app will work fine for now but act up later, their response was to contact Apple. Contact Apple? Netflix is the only app acting up. They asked if the problem is seen on other apps. I said my Mac is the only other place I watch Netflix. They responded, "Ah, the issue is the Apple TV since it works fine on your Mac."
"Seriously?" I said. The technology is different for each device. One is on a browser, the other is a device specific app. But they stuck with their mantra. Obviously, they're clueless and unwilling to expedite such issues to their app development team. Very pitiful customer service.
So I'm asking everyone here, is anyone else experiencing a Netflix app that runs ever more slowly the longer they use it? It acts like the app is sucking up memory until there's no more available, causing the scrolling to eventually stop scrolling, followed by the app becoming unresponsive all together.
I originated this thread. I've had a few discussions with Netflix about this and as others have reported, Netflix insists we contact Apple, which is ludicrous. The problem isn't with anything Apple. My most recent chat session is below.
This was a few weeks ago. Not surprisingly, I never was contacted afterwards. Netflix is headed down the path to failure by not responding to customer problems, something they cannot afford to do in an increasingly competitive environment. Will Netflix go the way of Blackberry and others? Companies too arrogant by their size to not see the approaching cliff.
Like any browser with too many tabs open, Apple TV uses memory keeping unused apps open. Netflix is affected more than others for some reason. The solution that works for me is to close all apps you currently are not watching. On your Apple remote, double click on the Home button (looks like a TV) and you will see all of the open apps displayed (similar to an iPad). Swipe left/right to select the apps, then swipe up to close the app. Netflix should run normally.
