Encrypted Messaging Project "Matrix" Suffers Extensive Cyber Attack

Encrypted Messaging Project "Matrix" Suffers Extensive Cyber Attack

April 12, 2019Mohit Kumar
Matrix—the organization behind an open source project that offers a protocol for secure and decentralized real-time communication—has suffered a massive cyber attack after unknown attackers gained access to the servers hosting its official website and data. Hackers defaced Matrix's website, and also stole unencrypted private messages, password hashes, access tokens, as well as GPG keys the project maintainers used for signing packages. The cyber attack eventually forced the organization to shut down its entire production infrastructure for several hours and log all users out of Matrix.org. So, if you have an account with Matrix.org service and do not have backups of your encryption keys or were not using server-side encryption key backup, unfortunately, you will not be able to read your entire encrypted conversation history. Matrix is an open source end-to-end encrypted messaging protocol that allows anyone to self-host a messaging service on their own servers, powering

Telegram Gained 3 Million New Users During WhatsApp, Facebook Outage

March 14, 2019Mohit Kumar
WhatsApp, Facebook, and Instagram faced a widespread outage yesterday with users from around the world reporting issues with sending messages on WhatsApp and Messenger, posting feeds on Facebook and accessing other features on the three Facebook-owned platforms. While the outage was quite troubling both for the social media giant and its millions of users, guess who benefits the most out of the incident? TELEGRAM. Pavel Durov, the founder of the popular secure messaging platform Telegram, claims to have had a surge in sign-ups within the last 24 hours, at the time duration when its rival messaging services were facing downtime. "I see 3 million new users signed up for Telegram within the last 24 hours," Durov wrote on his Telegram channel. "Good. We have true privacy and unlimited space for everyone." Telegram is an excellent alternative to Facebook's Messenger and WhatsApp services, offering users an optional end-to-end encrypted messaging feature,
Severe Bug Discovered in Signal Messaging App for Windows and Linux

Severe Bug Discovered in Signal Messaging App for Windows and Linux

May 12, 2018Swati Khandelwal
Security researchers have discovered a severe vulnerability in the popular end-to-end encrypted Signal messaging app for Windows and Linux desktops which could allow remote attackers to execute malicious code on recipients system just by sending a message—without requiring any user interaction. Discovered by Alfredo Ortega, a software security consultant from Argentina, the vulnerability was announced on Twitter just a few hours ago with a proof-of-concept video, demonstrating how a javascript payload sent over Signal for desktop app successfully got executed on the recipient's system. Although technical details of the vulnerability have not been revealed as of now, the issue appears to be a remote code execution vulnerability in Signal or at least something very close to persistent cross-site scripting (XSS) which eventually could allow attackers to inject malicious code onto targeted Windows and Linux systems. "For the time being, we can only confirm the execution
Hackers Exploiting 'Bitmessage' Zero-Day to Steal Bitcoin Wallet Keys

Hackers Exploiting 'Bitmessage' Zero-Day to Steal Bitcoin Wallet Keys

February 14, 2018Swati Khandelwal
Bitmessage developers have warned of a critical 'remotely executable' zero-day vulnerability in the PyBitmessage application that was being exploited in the wild. Bitmessage is a Peer-to-Peer (P2P) communications protocol used to send encrypted messages to users. Since it is decentralized and trustless communications, one need-not inherently trust any entities like root certificate authorities. Those who unaware, PyBitmessage is the official client for Bitmessage messaging service. According to Bitmessage developers, a critical zero-day remote code execution vulnerability, described as a message encoding flaw, affects PyBitmessage version 0.6.2 for Linux, Mac, and Windows and has been exploited against some of their users. "The exploit is triggered by a malicious message if you are the recipient (including joined chans). The attacker ran an automated script but also opened, or tried to open, a remote reverse shell," Bitmessage core developer Peter Šurda ex
WhatsApp Flaw Could Allow 'Potential Attackers' to Spy On Encrypted Group Chats

WhatsApp Flaw Could Allow 'Potential Attackers' to Spy On Encrypted Group Chats

January 10, 2018Swati Khandelwal
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

75,000 Turks Arrested So Far for Downloading Encrypted Messaging App

September 15, 2017Unknown
WARNING: If you are Turkish and using or have installed ByLock —a little-known encrypted messaging app—you could be detained by Turkish authorities. You might be thinking why??? Because using this app in Turkish is illegal since last year. The background story begins here... Remember the deadliest Turkey's failed coup attempt? In July 2016, a section of the Turkish military launched a coordinated operation—by deploying soldiers, tanks on the streets of major Turkish cities—to topple the government and unseat President Recep Tayyip Erdogan . The Turkish government blamed Muhammed Fethullah Gülen, a Turkish preacher who lives in the United States, for leading the July 15-16 attempted coup , though Gülen denied any involvement. In the aftermath of the coup attempt, Milli İstihbarat Teşkilatı (MİT), the Turkish intelligence agency investigated and found that the ByLock messaging app was used as a communication tool by tens of thousands of Gülen movement followers to c

Signal Messaging App Rolls Out Encrypted Video Calling

February 15, 2017Swati Khandelwal
WhatsApp and Facebook have so far the largest end-to-end encrypted video calling network of all, but now another popular end-to-end encrypted messaging app recommended by whistleblower Edward Snowden is ready to give them a really tough competition. The Signal app, which is widely considered the most secure of all other encrypted messaging apps, released video calling feature on Tuesday for both Android and iOS in a new update. Developed by open source software group Open Whisper System, Signal is a free and open source messaging application specially designed for Android and iOS users to make secure and encrypted messages and voice calls. Even the Signal Protocol powers the end-to-end encryption built into WhatsApp, Facebook Messenger, and Google Allo's Incognito mode as well. Signal has already been providing fully end-to-end encrypted chat and voice calling features, but the newly added feature will make it even easier for privacy conscious people to convey their inf

Using 'Signal' for Encrypted Chats? You Shouldn't Skip Its Next Update

September 16, 2016Mohit Kumar
Two Researchers have discovered a couple of vulnerabilities in Signal , the popular end-to-end encrypted messaging app recommended by whistleblower Edward Snowden. One of those vulnerabilities could allow potential attackers to add random data to the attachments of encrypted messages sent by Android users, while another bug could allow hackers to remotely crash vulnerable devices. The vulnerabilities have just been patched, but the updated version of Signal is yet available on the Github open source repository, and not on the Google's official Play Store for Android apps, leaving millions of privacy conscious people vulnerable to attacks. That means, if you have installed Signal messaging app via Google Play Store, like other millions of Android users, you are still vulnerable to hackers. Developed by open source software group Open Whisper System, Signal is a free and open source messaging application specifically designed for Android and iOS users to make secure and e

Ricochet — Most Secure Peer-to-Peer Encrypted Messenger that Sends No Metadata

February 23, 2016Swati Khandelwal
There are several encrypted messaging apps for mobile and desktop platforms that shipped with "The Most Secure" tagline but ends up in de-anonymizing the real identity of its users in some or the other way. In fact, very few encrypted messaging apps available today deal with the core problem of Metadata .  The majority of apps offer end-to-end encryption that kept the content of your messages away from prying eyes, but your metadata will still be accessible to them, which is enough to know who you really are, and who you're talking to. But, one messenger app stands out of the crowd by providing superb anonymity to its users, and it is dubbed as " Ricochet ." Ricochet is a peer-to-peer instant messaging system available for Windows, Mac, and Linux and you can trust it as the app has already cleared its first professional security audit carried out by cyber security company NCC Group .

Apple Can Still Read Your End-to-End Encrypted iMessages

January 25, 2016Swati Khandelwal
If you are backing up your data using iCloud Backup , then you need you watch your steps NOW! In government fight against encryption, Apple has positioned itself as a staunch defender of its user privacy by refusing the federal officials to provide encryption backdoors into its products. When it comes to Apple's iMessage service, the company claims that it can't read messages sent between its devices because they use end-to-end encryption, which apparently means that only you and the intended recipient can read it. Moreover, in case, if the federal authorities ask Apple to hand over messages related to any of its users, there is nothing with Apple to offer them. "If the government laid a subpoena to get iMessages, we can't provide it," Apple CEO Tim Cook told Charlie Rose back in 2014. "It is encrypted, and we do not have a key." But Wait! There are still hundreds of Millions of Apple users whose data are stored on Apple'
