Sccm Package Status Install Pending Amazon' title='Sccm Package Status Install Pending Amazon' />Hacking Cyber Security.What is a backdoor By definition Backdoor is a feature or defect of a computer system that allows surreptitious unauthorized access to data, either the backdoor is in encryption algorithm, a server or in an implementation, and doesnt matter whether it has previously been used or not.Yesterday, we published a story based on findings reported by security researcher Tobias Boelter that suggests Whats.App has a backdoor that could allow an attacker, and of course the company itself, to intercept your encrypted communication.The story involving the worlds largest secure messaging platform that has over a billion users worldwide went viral in few hours, attracting reactions from security experts, Whats.App team, and Open Whisper Systems, who partnered with Facebook to implement end to end encryption in Whats.App. Note I would request readers to read complete article before reaching out for a conclusion.And also, suggestions and opinions are always invited Whats the Issue.The vulnerability relies on the way Whats.Updates-waiting-to-be-installed.png' alt='Sccm Package Status Install Pending Amazon' title='Sccm Package Status Install Pending Amazon' />Even more Account Options.Sign in Search settings.App behaves when an end users encryption key changes.Whats. App, by default, trusts new encryption key broadcasted by a contact and uses it to re encrypt undelivered messages and send them without informing the sender of the change.In my previous article, I have elaborated this vulnerability with an easy example, so you can head on to read that article for better understanding.Facebook itself admitted to this Whats.Dear Experts, Here in my organization SCCM 2012 is configured.With the help of Expert Exchange Experts i have configured WSUS then Software updates.App issue reported by Boelter, saying that we were previously aware of the issue and might change it in the future, but for now its not something were actively working on changing.What Experts argued.According to some security experts Its not a backdoor, rather its a feature to avoid unnecessarily re verification of encryption keys upon automatic regeneration.Open Whisper Systems says There is no Whats.App backdoor, it is how cryptography works, and the MITM attack is endemic to public key cryptography, not just Whats.App. A spokesperson from Whats.App, acquired by Facebook in 2.Billion, says The Guardians story on an alleged backdoor in Whats.App is false. Whats.App does not give governments a backdoor into its systems.Whats. App would fight any government request to create a backdoor.Whats the fact Notably, none of the security experts or the company has denied the fact that, if required, Whats.App, on government request, or state sponsored hackers can intercept your chats.What all they have to say is Whats. Check Point Software Technologies Social Engineering Hacking . App is designed to be simple, and users should not lose access to messages sent to them when their encryption key is changed.Open Whisper Systems OWS criticized the Guardian reporting in a blog post saying, Even though we are the creators of the encryption protocol supposedly backdoored by Whats.App, we were not asked for comment.What Whats. App NO No one has said its an encryption backdoor instead this backdoor resides in the way how end to end encryption has been implemented by Whats.App, which eventually allows interception of messages without breaking the encryption.As I mentioned in my previous story, this backdoor has nothing to do with the security of Signal encryption protocol created by Open Whisper Systems.Its one of the most secure encryption protocols if implemented correctly.Then Why Signal is more Secure than Whats.App You might be wondering why Signal private messenger is more secure than Whatsapp, while both use the same end to end encryption protocol, and even recommended by the same group of security experts who are arguing Whats.App has no backdoor.Its because there is always room for improvement.The signal messaging app, by default, allows a sender to verify a new key before using it.Whereas, Whats. App, by default, automatically trusts the new key of the recipient with no notification to the sender.And even if the sender has turned on the security notifications, the app notifies the sender of the change only after the message is delivered.So, here Whats. App chose usability over security and privacy.Its not about Do We Trust Whats.AppFacebook. Whats.App says it does not give governments a backdoor into its systems.No doubt, the company would definitely fight the government if it receives any such court orders and currently, is doing its best to protect the privacy of its one billion plus users.But what about state sponsored hackers Because, technically, there is no such reserved backdoor that only the company can access.Why Verifying Keys Feature Cant Protect You Whats.App also offers a third security layer using which you can verify the keys of other users with whom you are communicating, either by scanning a QR code or by comparing a 6.But heres the catch This feature ensure that no one is intercepting your messages or calls at the time you are verifying the keys, but it does not ensure that no one, in the past had intercepted or in future will intercept your encrypted communication, and there is no way, currently, that would help you identify this.Whats. App Prevention against such MITM Attacks are Incomplete.Whats. App is already offering a security notifications feature that notifies users whenever a contacts security code changes, which you need to turn on manually from app settings.But this feature is not enough to protect your communication without the use of another ultimate tool, which is Common Sense.Have you received a notification indicating that your contacts security code has changed Instead of offering Security by Design, Whats.App wants its users to use their common sense not to communicate with the contact whose security key has been changed recently, without verifying the key manually.The fact that Whats.App automatically changes your security key so frequently for some reasons that one would start ignoring such notifications, making it practically impossible for users to actively looking each time for verifying the authenticity of session keys.What Whats. App should do Without panicking all one billion plus users, Whats.App can, at least Stop regenerating users encryption keys so frequently I clearly dont know why the company does so.Give an option in the settings for privacy conscious people, which if turned on, would not automatically trust new encryption key and send messages until manually accepted or verified by users.I also hate using two apps for communicating with my friends and work colleagues i.Signal for privacy and Whats.App because everyone uses it.
