Hackers Can Manipulate Media Files You Receive Via WhatsApp and Telegram

Hackers Can Manipulate Media Files You Receive Via WhatsApp and Telegram

July 16, 2019Mohit Kumar
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
Zoom RCE Flaw Also Affects Its Rebranded Versions RingCentral and Zhumu

Zoom RCE Flaw Also Affects Its Rebranded Versions RingCentral and Zhumu

July 16, 2019Swati Khandelwal
The same security vulnerabilities that were recently reported in Zoom for macOS also affect two other popular video conferencing software that under the hood, are just a rebranded version of Zoom video conferencing software. Security researchers confirmed The Hacker News that RingCentral, used by over 350,000 businesses, and Zhumu, a Chinese version of Zoom, also runs a hidden local web server on users' computers, just like Zoom for macOS. The controversial local web server that has been designed to offer an automatic click-to-join feature was found vulnerable to remote command injection attacks through 3rd-party websites. Security researcher Jonathan Leitschuh initially provided a proof-of-concept demonstrating how the vulnerable web server  could eventually allow attackers to turn on users laptop's webcam and microphone remotely. The flaw was later escalated to remote code execution attack by another security researcher, Karan Lyons , who has now published a new v
iOS URL Scheme Could Let App-in-the-Middle Attackers Hijack Your Accounts

iOS URL Scheme Could Let App-in-the-Middle Attackers Hijack Your Accounts

July 15, 2019Swati Khandelwal
Security researchers have illustrated a new app-in-the-middle attack that could allow a malicious app installed on your iOS device to steal sensitive information from other apps by exploiting certain implementations of Custom URL Scheme . By default on Apple's iOS operating system, every app runs inside a sandbox of its own, which prevent all apps installed on the same device from accessing each other's data. However, Apple offers some methods that facilitate sending and receiving very limited data between applications. One such mechanism is called URL Scheme, also known as Deep Linking, that allows developers to let users launch their apps through URLs, like facetime:// , whatsapp:// , fb-messenger:// . For example, when you click "Sign in with Facebook" within an e-commerce app, it directly launches the Facebook app installed on your device and automatically process the authentication. In the background, that e-commerce app actually triggers the URL Sch

This Flaw Could Have Allowed Hackers to Hack Any Instagram Account Within 10 Minutes

July 15, 2019Mohit Kumar
Watch out! Facebook-owned photo-sharing service has recently patched a critical vulnerability that could have allowed hackers to compromise any Instagram account without requiring any interaction from the targeted users. Instagram is growing quickly—and with the most popular social media network in the world after Facebook, the photo-sharing network absolutely dominates when it comes to user engagement and interactions. Despite having advanced security mechanisms in place, bigger platforms like Facebook, Google, LinkedIn, and Instagram are not completely immune to hackers and contain severe vulnerabilities. Some vulnerabilities have recently been patched , some are still under the process of being fixed, and many others most likely do exist, but haven't been found just yet. Details of one such critical vulnerability in Instagram surfaced today on the Internet that could have allowed a remote attacker to reset the password for any Instagram account and take complete contr
Zoom Video Conferencing for macOS Also Vulnerable to Critical RCE Flaw

Zoom Video Conferencing for macOS Also Vulnerable to Critical RCE Flaw

July 13, 2019Mohit Kumar
The chaos and panic that the disclosure of privacy vulnerability in the highly popular and widely-used Zoom video conferencing software created earlier this week is not over yet. As suspected, it turns out that the core issue—a locally installed web server by the software—was not just allowing any website to turn on your device webcam, but also could allow hackers to take complete control over your Apple's Mac computer remotely. Reportedly, the cloud-based Zoom meeting platform for macOS has also been found vulnerable to another severe flaw (CVE-2019-13567) that could allow remote attackers to execute arbitrary code on a targeted system just by convincing users into visiting an innocent looking web-page. As explained in our previous report by Swati Khandelwal, the Zoom conferencing app contained a critical vulnerability ( CVE-2019-13450 ) that resides in the way its click-to-join feature is implemented, which automatically turns on users' webcam when they visit an in
Facebook to Pay $5 Billion Fine to Settle FTC Privacy Investigation

Facebook to Pay $5 Billion Fine to Settle FTC Privacy Investigation

July 13, 2019Swati Khandelwal
After months of negotiations, the United States Federal Trade Commission (FTC) has approved a record $5 billion settlement with Facebook over its privacy investigation into the Cambridge Analytica scandal . The settlement will put an end to a wide-ranging probe that began more than a year ago and centers around the violation of a 2011 agreement Facebook made with the FTC that required Facebook to gain explicit consent from users to share their personal data. The FTC launched an investigation into the social media giant last year after it was revealed that the company allowed Cambridge Analytica access to the personal data of around  87 million Facebook users without their explicit consent. Now, according to a new report published by the Wall Street Journal, the FTC commissioners this week finally voted to approve a $5 billion settlement, with three Republicans voting to approve the deal and two Democrats against it. Facebook anticipated the fine to between $3 billion and

New Malware Replaced Legit Android Apps With Fake Ones On 25 Million Devices

New Malware Replaced Legit Android Apps With Fake Ones On 25 Million Devices

Are you sure the WhatsApp app you are using on your Android device is legitimate, even if it's working perfectly as intended? ...Or the JioTV, AppLock, HotStar, Flipkart, Opera Mini or Truecaller app—if you have installed any of these? I'm asking this because cybersecurity researchers just yesterday revealed eye-opening details about a widespread Android malware campaign wherein attackers silently replaced installed legitimate apps with their malicious versions on nearly 25 million mobile phones. Now the important question here is how they're doing it and why? According to researchers at Check Point, attackers are distributing a new kind of Android malware that disguises itself as innocent-looking photo editing, adult entertainment, or gaming apps and available through widely used third-party app stores. Dubbed Agent Smith , the malware takes advantage of multiple Android vulnerabilities, such as the  Janus flaw and the Man-in-the-Disk flaw , and injects malic
