A picture is worth a thousand words, but a GIF is worth a thousand pictures. Today, the short looping clips, GIFs are everywhere—on your social media, on your message boards, on your chats, helping users perfectly express their emotions, making people laugh, and reliving a highlight. But what if an innocent-looking GIF greeting with Good morning, Happy Birthday, or Merry Christmas message hacks your smartphone? Well, not a theoretical idea anymore. WhatsApp has recently patched a critical security vulnerability in its app for Android, which remained unpatched for at least 3 months after being discovered, and if exploited, could have allowed remote hackers to compromise Android devices and potentially steal files and chat messages. WhatsApp Remote Code Execution Vulnerability The vulnerability, tracked as CVE-2019-11932 , is a double-free memory corruption bug that doesn't actually reside in the WhatsApp code itself, but in an open-source GIF image parsing library th

Mistakenly sent a picture to someone via WhatsApp that you shouldn't have? Well, we've all been there, but what's more unfortunate is that the 'Delete for Everyone' feature WhatsApp introduced two years ago contains an unpatched privacy bug, leaving its users with false sense of privacy. WhatsApp and its rival Telegram messenger offer "Delete for Everyone," a potentially life-saving feature on which millions of people today rely to escape the awkwardness of mistakenly sending messages / pictures / videos to the wrong person. As the name indicates, the ' Delete for Everyone ' feature is intended to unsend mistakenly sent inappropriate messages—including text, photos and videos—from the recipient's phone, or from the phones of all members of a group. In the case of WhatsApp, the feature is only available within 1 hour, 8 minutes, and 16 seconds of sending a message you want to delete, which is fine and a fair use case. However, it tur

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

If you think that the media files you receive on your end-to-end encrypted secure messaging apps can not be tampered with, you need to think again. Security researchers at Symantec yesterday demonstrated multiple interesting attack scenarios against WhatsApp and Telegram Android apps, which could allow malicious actors to spread fake news or scam users into sending payments to wrong accounts. Dubbed " Media File Jacking ," the attack leverages an already known fact that any app installed on a device can access and rewrite files saved in the external storage, including files saved by other apps installed on the same device. WhatsApp and Telegram allow users to choose if they want to save all incoming multimedia files on internal or external storage of their device. However, WhatsApp for Android by default automatically stores media files in the external storage, while Telegram for Android uses internal storage to store users files that are not accessible to any othe

Whatsapp has recently patched a severe vulnerability that was being exploited by attackers to remotely install surveillance malware on a few "selected" smartphones by simply calling the targeted phone numbers over Whatsapp audio call. Discovered, weaponized and then sold by the Israeli company NSO Group that produces the most advanced mobile spyware on the planet, the WhatsApp exploit installs Pegasus spyware on to Android and iOS devices. According to an advisory published by Facebook, a buffer overflow vulnerability in WhatsApp VOIP stack allows remote attackers to execute arbitrary code on target phones by sending a specially crafted series of SRTCP packets. Apparently, the vulnerability, identified as CVE-2019-3568 , can successfully be exploited to install the spyware and steal data from a targeted Android phone or iPhone by merely placing a WhatsApp call, even when the call is not answered. Also, the victim would not be able to find out about the intrusion af

What if just receiving a video call on WhatsApp could hack your smartphone? This sounds filmy, but Google Project Zero security researcher Natalie Silvanovich found a critical vulnerability in WhatsApp messenger that could have allowed hackers to remotely take full control of your WhatsApp just by video calling you over the messaging app. The vulnerability is a memory heap overflow issue which is triggered when a user receives a specially crafted malformed RTP packet via a video call request, which results in the corruption error and crashing the WhatsApp mobile app. Since the vulnerability affect RTP (Real-time Transport Protocol) implementation of Whatsapp, the flaw affects Android and iOS apps, but not WhatsApp Web that relies on WebRTC for video calls. Silvanovich also published a proof-of-concept exploit, along with the instructions for reproducing the WhatsApp attack. Although the proof-of-concept published by Silvanovich only triggers memory corruption, another Go

Facebook announced a whole lot of new features at its 2018 Facebook F8 developers conference, including Dating on Facebook, letting users clear their web browsing history, real-time language translation within Messenger, and many more. Besides announcing exciting features for its social media platform, Facebook CEO Mark Zuckerberg also gave us a quick look at the features Facebook introduced for companies that it owns, like WhatsApp and Instagram. During Facebook's F8 conference on Tuesday, Zuckerberg announced a long-awaited feature for WhatsApp— Group Video Calling . Yes, you heard that right. WhatsApp would soon be adding a group video calling feature to the popular end-to-end messaging app, making it possible for its over billion users to have face-to-face conversations with multiple people at once. Although there are not many details about the WhatsApp group video calling feature at this moment, it is clear that WhatsApp will now allow four people to have one-on-one

A more dramatic revelation of 2018—an outsider can secretly eavesdrop on your private end-to-end encrypted group chats on WhatsApp and Signal messaging apps. Considering protection against three types of attackers—malicious user, network attacker, and malicious server—an end-to-end encryption protocol plays a vital role in securing instant messaging services. The primary purpose of having end-to-end encryption is to stop trusting the intermediate servers in such a way that no one, not even the company or the server that transmits the data, can decrypt your messages or abuse its centralized position to manipulate the service. In order words—assuming the worst-case scenario—a corrupt company employee should not be able to eavesdrop on the end-to-end encrypted communication by any mean. However, so far even the popular end-to-end encrypted messaging services, like WhatsApp, Threema and Signal, have not entirely achieved zero-knowledge system. Researchers from Ruhr-Universität

Cybercriminals are known to take advantage of everything that's popular among people in order to spread malware, and Google's official Play Store has always proved no less than an excellent place for hackers to get their job done. Yesterday some users spotted a fake version of the most popular WhatsApp messaging app for Android on the official Google Play Store that has already tricked more than one million users into downloading it. Dubbed Update WhatsApp Messenger , came from an app developer who pretended to be the actual WhatsApp service with the developer title "WhatsApp Inc."—the same title the actual WhatsApp messenger uses on Google Play. You might be wondering how the sneaky app developer was able to use the same title as the legitimate Facebook-owned maker of the messaging client—thanks to a Unicode character space. The app maker added a Unicode character space after the actual WhatsApp Inc. name, which in computer code reads WhatsApp+Inc%C2%A0 .

Have you ever felt like wishing of sending any type of file immediately to your friends and office colleagues on WhatsApp directly, instead of just contacts, images or documents? Well, now you can… The latest version of WhatsApp for Android and iOS now allows users to send and receive any type of files, whether it's .mp3, .avi, .php, zip files, or even APKs. The company last month rolled out this feature to its beta users for Android, and now after being tested successfully, the feature is being released to all WhatsApp users in the latest public update for iOS and Android. The ability to send any file types also works on the WhatsApp-Web client . And of course, there's a file-size limit: Android users can send files up to 100MB iOS users can send files up to 128MB While WhatsApp-web users can only send up to 64MB To send any file format you just need to select 'Document' from 'Attach.' Additionally, the latest update of the app will allow you to select photos

The government has once again started asking for backdoor in encrypted services, arguing that it can not give enough security to its citizens because the terrorists are using encrypted apps to communicate and plot an attack. Following last week's terrorist attack in London, the UK government is accusing technology firms to give terrorists "a place to hide," saying Intelligence agencies must have access to encrypted messaging applications such as WhatsApp to prevent such attacks. According to authorities , the killer, Khalid Masood, 52, was active on WhatsApp messaging app just two minutes before he attacked Britain's Houses of Parliament in Westminster that killed four people. Here's what Amber Rudd, Britain's Home Secretary said while speaking at BBC's Andrew Marr Show on Sunday: "We need to make sure that organizations like WhatsApp, and there are plenty of others like that, don't provide a secret place for terrorists to communicate

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 doesn't 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 WhatsApp has a backdoor that "could allow" an attacker, and of course the company itself, to intercept your encrypted communication. The story involving the world's largest secure messaging platform that has over a billion users worldwide went viral in few hours, attracting reactions from security experts, WhatsApp team, and Open Whisper Systems, who partnered with Facebook to implement end-to-end encryption in WhatsApp. Note: I would request readers to read complete article before reaching out for a conclusion. And also, suggestions and opinions are

Important Update — Most Security Experts argued, " It's not a backdoor, rather it's a feature ," but none of them denied the fact that, if required, WhatsApp or a hacker can intercept your end-to-end encrypted chats. Read detailed explanation on arguments in my latest article. Most people believe that end-to-end encryption is the ultimate way to protect your secret communication from snooping, and it does, but it can be intercepted if not implemented correctly. After introducing " end-to-end encryption by default " last year, WhatsApp has become the world's largest secure messaging platform with over a billion users worldwide. But if you think your conversations are completely secure in a way that no one, not even Facebook, the company that owned WhatsApp, can intercept your messages then you are highly mistaken, just like most of us and it's not a new concept. Here's the kick: End-to-end encrypted messaging service, such as WhatsApp and Te

In August, Facebook introduced a hugely controversial data sharing plan to start harvesting data from its WhatsApp messaging app from September 25 for delivering more relevant ads on the social network. Many users were not happy with the move, because there was no real way of opting out from the data sharing – WhatsApp users could only do so within a short period – and even if users did opt out then, some data would still be shared. Eventually, some countries like Britain stood up and opposed the decision. The Information Commissioner's Office (ICO) of the United Kingdom has asked Facebook and WhatsApp to better explain the changes to its customers in the U.K. And if they don't, the ICO could hand out a heavy fine. What's the good news? In response, the social media giant has agreed to "pause" sharing of data, including their phone numbers, between WhatsApp and Facebook in Britain to target advertisements on its core social network. "We have

WhatsApp is, no doubt, the largest end-to-end encrypted messaging network that allows over billion of its users to send messages, photos, videos, voice messages, documents, and calls that are secure from falling into the wrong hands. And now it seems like WhatsApp is rolling out a much-awaited feature for the new beta versions of its Android app: Video Calling . New beta version 2.16.318 of WhatsApp brings the ability for users to conduct free video calls, though it is not clear, at this moment, whether the Video calling feature of WhatsApp provides end-to-end encryption. In order to activate video calls, you simply need to pull up a contact in the WhatsApp app, tap on the call icon and choose "Video Call." You can also go directly to the Calls tab, to begin with the option. The Video calls will only work if both the caller as well as the receiver have the same beta build of WhatsApp that supports the feature. If not, you will be notified of an error message that

Just last month, the most popular messaging app WhatsApp updated its privacy policy and T&Cs to start sharing its user data with its parent company, and now both the companies are in trouble, at least in Germany and India. Both Facebook, as well as WhatsApp, have been told to immediately stop collecting and storing data on roughly 35 Million WhatsApp users in Germany. The Hamburg Commissioner for Data Protection and Freedom of Information Johannes Caspar even ordered Facebook on Tuesday to delete all data that has already been forwarded to WhatsApp since August. Also in India, the Delhi High Court on September 23 ordered WhatsApp to delete all users' data from its servers up until September 25 when the company's new privacy policy came into effect. When Facebook first acquired WhatsApp for $19 billion in cash in 2014, WhatsApp made a promise that its users' data would not be shared between both companies. But now apparently this has changed, which, according to Caspa

Nothing comes for Free, as "Free" is just a relative term used by companies to develop a strong user base and then use it for their own benefits. The same has been done by the secure messaging app WhatsApp, which has now made it crystal clear that the popular messaging service will begin sharing its users' data with its parent company, Facebook. However, WhatsApp is offering a partial opt-out for Facebook targeted ads and product related purposes, which I will let you know later in this article, but completely opting out of the data-sharing does not seem to be possible. Let's know what the company has decided to do with your data. Of course, Facebook is willing to use your data to sell more targeted advertisements. WhatsApp introduced some significant changes to its privacy policy and T&Cs today which, if accepted once, gives it permission to connect users' Facebook accounts to WhatsApp accounts for the first time, giving Facebook more data about us

In Brief Viber, the popular mobile messaging app announced Tuesday that it has added full end-to-end encryption for video, voice and text message services for its millions of users. Here, the end-to-end encryption means only you and the person you are communicating with can read the content, and nobody in between, not even the company and if court orders company to provide user data, they will get only the heaps of encrypted data. Viber is the latest messaging platform to join WhatsApp , Telegram , and Apple iMessage , who strengthened their default privacy features in recent times. Founded in 2010 and acquired by Japanese e-commerce titan Rakuten for $900 Million in 2014, Viber is currently being used by more than 700 Million users globally across Android, iOS, Windows Phone, and desktop, the company claimed in a blog post published today. The move comes just a couple of weeks after Facebook-owned Whatsapp messaging app implemented full end-to-end encryption by default

Although everyone, including Apple, was worried about the iPhone hacking tool used by the Federal Bureau of Investigation (FBI) to access data on iPhone belonged to the San Bernardino shooter, the FBI director said the hack does not work on an iPhone 5S or later. FBI Director James Comey said Wednesday that the agency was able to avoid a prolonged legal battle with Apple by buying a tool from a private source to hack into terrorist Syed Farook's iPhone 5C. Apple was engaged in a legal battle with the Department of Justice (DOJ) for a month over a court order that forces the company to write new software, which could disable passcode protection on Farook's iPhone to help them access data on it. Apple refused to comply with the order, so the FBI worked with a third-party firm, most likely the Israeli mobile forensic firm Cellebrite, and was successfully able to access data on the locked iPhone used in the San Bernardino shooting incident last year. But speaking to the
