Signal is Most Secure Messenger, 'Useless Data' Obtained by FBI Proves It All

Signal is Most Secure Messenger, 'Useless Data' Obtained by FBI Proves It All
Oct 04, 2016
Do you trust your messaging app even though it uses end-to-end encryption? As I previously said end-to-end encryption doesn't mean that your messages are secure enough to hide your trace. It's because most of the messaging apps still record and store a lot of metadata on your calls and messages that could reveal some of your personal information including dates and durations of communication, as well as the participants' phone numbers. Apple's iMessage app is the most recent and best example of this scenario. Just recently it was reported that the company stores a lot of information about its end-to-end encrypted iMessage, that could reveal your contacts and location, and even share this data with law enforcement via court orders. But if you are using open source end-to-end encrypted Signal   app, you are on the safer side. Trust me! As we previously reported that the Signal app, which is widely considered the most secure of all other encrypted messaging a

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

Using 'Signal' for Encrypted Chats? You Shouldn't Skip Its Next Update
Sep 16, 2016
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

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future
Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward. Figure 1 The Pu

Germany and France declare War on Encryption to Fight Terrorism

Germany and France declare War on Encryption to Fight Terrorism
Aug 25, 2016
Yet another war on Encryption! France and Germany are asking the European Union for new laws that would require mobile messaging services to decrypt secure communications on demand and make them available to law enforcement agencies. French and German interior ministers this week said their governments should be able to access content on encrypted services in order to fight terrorism , the Wall Street Journal reported . French interior minister Bernard Cazeneuve went on to say that the encrypted messaging apps like Telegram and WhatsApp " constitute a challenge during investigations, " making it difficult for law enforcement to conduct surveillance on suspected terrorists. Also Read:  How to Send and Receive End-to-End Encrypted Emails The proposal calls on the European Commission to draft a law that would " impose obligations on operators who show themselves to be non-cooperative, in particular when it comes to withdrawing illegal content or decrypting me

Facebook Messenger adds End-to-End Encryption (Optional) for Secret Conversations

Facebook Messenger adds End-to-End Encryption (Optional) for Secret Conversations
Jul 08, 2016
Facebook has begun rolling out end-to-end encryption for its Messenger app, thus making its users' conversations completely private. The end-to-end encryption feature, dubbed " Secret Conversations ," will allow Messenger users to send and receive messages in a way that no one, including the FBI with a warrant, hackers and not even Facebook itself, can intercept them. But, this new feature will currently be available only to a small number of users for testing. So if you are one of those lucky users, you will be able to send end-to-end encrypted Secret Conversations through your Messenger app. Rest of the Messenger users will get Secret Conversations feature later this summer or in early fall, the company wrote in a Facebook newsroom post published today. Sounds exciting, right? But, there's a catch: Your conversations on Messenger will not be end-to-end encrypted by default, like what WhatsApp and Apple are offering. Instead, Facebook will require

​DARPA Wants To Build Ultra Secure Messaging App for US Military

​DARPA Wants To Build Ultra Secure Messaging App for US Military
Apr 24, 2016
Just last month, DARPA launched a project dubbed "Improv," inviting hackers to transform simple household appliances into deadly weapons . Now, the Defense Advanced Research Projects Agency is finding someone in the private sector to develop a hacker-proof " secure messaging and transaction platform " for the U.S. military. Darpa wants researchers to create a secure messaging and transaction platform that should be accessible via the web browser or standalone native application. The secure messaging app should " separate the message creation, from the transfer (transport) and reception of the message using a decentralized messaging backbone to allow anyone anywhere the ability to send a secure message or conduct other transactions across multiple channels traceable in a decentralized ledger, " agency's  notice explains. In simple words, DARPA aims to create a secure messaging service that not only implements the standard encryption and se

Apr 05, 2016
WhatsApp is updating its messaging app so that every text message and voice call will be encrypted for the company's one billion users. Yes, Whatsapp has finally implemented full end-to-end encryption , as promised a year ago. This means, from now every message, image or voice call you made will be secured by end-to-end encryption so that only you and the person you're communicating with can read the content of the message, and nobody in between, not even WhatsApp. In other words, this also means that WhatsApp would not be able to comply with any court order that demands access to the content of any conversation happens over its service. Starting today, you will see a notification on your WhatsApp conversation screen as your messenger becomes end-to-end encrypted, as shown in the screenshot. "Message you send to this chat and calls are now secured with end-to-end encryption. Tap for more info."  "This is because your messages are secured with a lock,

Feb 26, 2016
Apple is serious this time to enhance its iPhone security that even it can not hack. To achieve this the company has hired one of the key developers of Signal — World's most secure, open source and encrypted messaging app. Frederic Jacobs, who worked to develop Signal, announced today that he is joining Apple this summer to work as an intern in its CoreOS security team. "I'm delighted to announce that I accepted an offer to be working with the CoreOS security team at Apple this summer," Jacobs tweeted Thursday. Signal app is widely popular among the high-profile privacy advocates, security researchers, journalists and whistleblowers for its clean and open source code, and even the NSA whistleblower Edward Snowden uses it every day.

Ricochet — Most Secure Peer-to-Peer Encrypted Messenger that Sends No Metadata
Feb 23, 2016
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 .

WhatsApp Blocks Links to Telegram Messenger (Its biggest Competitor)

WhatsApp Blocks Links to Telegram Messenger (Its biggest Competitor)
Dec 01, 2015
It seems like Facebook-owned popular messaging service WhatsApp is blocking links to rival messaging applications – at least Telegram app  for now. Telegram users are noticing that WhatsApp is blocking any links to the privacy-oriented messaging service Telegram.me. Although users are free to send or receive Telegram links on WhatsApp, the links appear as non-clickable that you cannot copy or forward. This strange behavior was first noticed this morning by Telegram users over on Reddit. The URLs – which are generally automatically made clickable – still appeared as plain text messages, but they didn't register as hyperlinks, blocking users from copying or forwarding them to other users or other apps.

The terrorist groups are encouraging its followers to use Telegram to make their propaganda invisible from law enforcement, but some security experts believe that Telegram may not be as secure as jihadi advocates may like to believe. Telegram is an end-to-end encrypted messaging service that has been adopted by a lot more people than ISIS — as of last year, the company claimed more than 50 Million Telegram users sending 1 Billion messages per day.

Is Telegram Really Secure?

Mar 05, 2014
With revelations of NSA spying and some of the most jaw-dropping surveillance leaks, many people feel unencrypted and central-server service is bad in most of the cases, but end-to-end encryption can be used to reduce this problem. Worldwide Government surveillance raises privacy concerns and acquisition of WhatsApp by Facebook also made us think about the security concern with chat applications as well; though it was not so secure previously. People who care about having their SMS and Instant messages protected from prying eyes, now they can use end-to-end encrypted services, like  TextSecure .  It is a free Android-based messaging app, completly open-source , easy to use and designed with privacy in mind. Encrypting the stored data on the servers is as important as transferring data over an encrypted connection, but the most important factor of the encryption is that ' who has the decryption key '. If the company has the keys, then Government could snoop through your fi
