A zero-day vulnerability has been discovered in the desktop version for end-to-end encrypted Telegram messaging app that was being exploited in the wild in order to spread malware that mines cryptocurrencies such as Monero and ZCash. The Telegram vulnerability was uncovered by security researcher Alexey Firsh from Kaspersky Lab last October and affects only the Windows client of Telegram messaging software. The flaw has actively been exploited in the wild since at least March 2017 by attackers who tricked victims into downloading malicious software onto their PCs that used their CPU power to mine cryptocurrencies or serve as a backdoor for attackers to remotely control the affected machine, according to a blogpost on Securelist. Here's How Telegram Vulnerability Works The vulnerability resides in the way Telegram Windows client handles the RLO (right-to-left override) Unicode character (U+202E), which is used for coding languages that are written from right to left, li...

On one end, where governments of countries like U.K is criticizing end-to-end encryption and considering to ban the encrypted communication apps like Snapchat, CryptoCat, WhatsApp and Apple’s iMessage. On the other hand, the Internet community has come up with a new and rather more secure encrypted communication app. Dubbed Peerio , an " encrypted productivity suite " designed to offer much more usable alternative to PGP email and file encryption, so that every individual user and business can encrypt everything from Instant Messages to online file storage. Peerio, released on Wednesday, is designed by 24-year-old Nadim Kobeissi – the creator of the end-to-end encrypted group messaging app Cryptocat and the encrypted file-sharing app MiniLock . " With Peerio everything you share or communicate with your team is secured with state-of-the-art encryption , and it’s as easy as using Gmail. You don’t need to learn to use it, " Kobeissi told Wired. ...

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...

The identity of the second threat actor behind the Golden Chickens malware has been uncovered courtesy of a "fatal" operational security blunder, cybersecurity firm eSentire said. The individual in question, who lives in Bucharest, Romania, has been given the codename Jack. He is one of the two criminals operating an account on the Russian-language Exploit.in forum under the name "badbullzvenom," the other being " Chuck from Montreal ." eSentire characterized Jack as the true mastermind behind Golden Chickens. Evidence unearthed by the Canadian company shows that he is also listed as the owner of a vegetable and fruit import and export business. "Like 'Chuck from Montreal,' 'Jack' uses multiple aliases for the underground forums, social media, and Jabber accounts, and he too has gone to great lengths to disguise himself," eSentire researchers Joe Stewart and Keegan Keplinger said . "'Jack' has taken great pa...

Privacy conscious phone users are being offered a new app that claims to be the world's first totally secure messaging service. A London-based iPhone messaging app claims to be unhackable and is offering reward to anyone who can intercept a message sent by it.  Redact believes that messages sent via the app are completely secure, and to prove it a reward of £10,000 has been offered. The application creates a secure and encrypted peer-to-peer network between two iPhones, with messages sent directly from one phone to another and not through the company's servers.  The company has already offered its Secure Messenger service for free to MPs and submitted the technology to CESG, the Government's National Technical Authority for Information Assurance, which provides advice on the security of communications and electronic data. With Redact there are no user names, phone numbers or email addresses. Instead, new users are automatically assigned a unique PIN, simi...

Twitter has been adopting new trends at a snail's pace. But it’s better to be late than never. Since 2013 people were speculating that Twitter will bring end-to-end encryption to its direct messages, and finally almost 5 years after the encryption era began, the company is now testing an end-to-end encrypted messaging on Twitter. Dubbed " Secret Conversation ," the feature has been spotted in the latest version of Android application package (APK) for Twitter by Jane Manchun Wong, a computer science student at the University of Massachusetts Dartmouth. End-to-end encryption allows users to send and receive messages in a way that no one, be it an FBI agent with a warrant, hacker or even the service itself, can intercept them. However, it seems like the Secret Conversation feature has currently been available only to a small number of users for testing. So, if you are one of those lucky ones, you will be able to send end-to-end encrypted Secret Conversation thro...

Facebook's Free Basics Internet service has been Blocked in India. The Telecom Regulatory Authority of India (TRAI) has banned mobile carriers and broadband providers to charge customers based on what services or content they access over the Internet. Under Prohibition of Discriminatory Tariffs for Data Services Regulations, 2016, "no service provider shall offer or charge discriminatory tariffs for data services on the basis of content." With this, Facebook's Free Basics is dead in India. All Zero-Rated Internet Services are BLOCKED!  It is not just Facebook's Free Basics Internet program that has been blocked inside the country, but also the zero-rated internet services altogether. Zero-rated internet services means those services that allow people access to some websites and web services without utilizing any of their mobile data allowance. Under the new regulation, no such services are now allowed. Free Basics (previously known by Int...

Facebook has introduced a new feature in its platform that has been designed to make it easier for bug bounty hunters to find security flaws in Facebook, Messenger, and Instagram Android applications. Since almost all Facebook-owned apps by default use security mechanisms such as Certificate Pinning to ensure integrity and confidentiality of the traffic, it makes it harder for white hat hackers and security researchers to intercept and analyze network traffic to find server-side security vulnerabilities. For those unaware, Certificate Pinning is a security mechanism designed to prevent users of an application from being a victim of network-based attacks by automatically rejecting the whole connection from sites that offer bogus SSL certificates. Dubbed " Whitehat Settings ," the new option now lets researchers easily bypass Certificate Pinning on the Facebook-owned mobile apps by: Disabling Facebook's TLS 1.3 support Enabling proxy for Platform API requests ...

A new computer worm is denying Facebook users access to their accounts. The worm, named "W32.Yimfoca" by the security company Symantec, spreads through Yahoo! Messenger and specifically targets Facebook users. It forces them to complete surveys before they can log into their profiles. The worm begins by sending an instant message containing a corrupted link. When a user clicks the link, the worm installs malware on their system. Later, when users visit Facebook, they see a message stating, "Your account is suspended. To make your account active, you need to complete one of these surveys," followed by a list of options like "Test Your Celebrity IQ here" and "Win a FREE iPhone 4." If users choose to fill out a survey, another message appears: "You have only 3 minutes to fill out the selected survey or you will not have access to your account." Each time a survey is completed, the creators of the worm earn $1, according to Symantec. The ...

Facebook knows a lot about you, your likes and dislikes—it's no surprise. But do you know, if you have installed Facebook Messenger app on your Android device, there are chances that the company had been collecting your contacts, SMS, and call history data at least until late last year. A tweet from Dylan McKay, a New Zealand-based programmer, which received more than 38,000 retweets (at the time of writing), showed how he found his year-old data—including complete logs of incoming and outgoing calls and SMS messages—in an archive he downloaded (as a ZIP file) from Facebook. Facebook was collecting this data on its users from last few years, which was even reported earlier in media, but the story did not get much attention at that time. Since Facebook had been embroiled into controversies over its data sharing practices after the Cambridge Analytica scandal last week, tweets from McKay went viral and has now fueled the never-ending privacy debate. A Facebook spokespe...

Microsoft's 'Cortana', Google's 'Google Now', Apple's 'Siri', Now meet Facebook's 'M.' Facebook's announcement to introduce their Personal Digital Assistant “M” comes with powers within the Facebook Messenger. It is a similar virtual assistant like Google Now, Apple's Siri and Microsoft's smart digital assistant Cortana. It seems that all the intelligence that resides within the personal digital assistants already in the market are nothing in front of M's capabilities, according to the Facebook post by David Marcus , Vice President of Messaging Products at Facebook. Three days ago, Microsoft had boosted the powers of Android users by making Cortana accessible on Android devices. Now listening to Facebook's launch of 'M', rival companies would have definitely face-palmed! What Can I Help You With? The virtual assistant software "M" is truly going to support you by doing the ...

An active Android malware campaign dubbed eXotic Visit has been primarily targeting users in South Asia, particularly those in India and Pakistan, with malware distributed via dedicated websites and Google Play Store. Slovak cybersecurity firm said the activity, ongoing since November 2021, is not linked to any known threat actor or group. It's tracking the group behind the operation under the name  Virtual Invaders . "Downloaded apps provide legitimate functionality, but also include code from the open-source Android  XploitSPY RAT ," ESET security researcher Lukáš Štefanko  said  in a technical report released today. The campaign is said to be highly targeted in nature, with the apps available on Google Play having negligible number of installs ranging from zero to 45. The apps have since been taken down. The fake-but-functional apps primarily masquerade as messaging services like Alpha Chat, ChitChat, Defcom, Dink Messenger, Signal Lite, TalkU, WeTalk, Wicke...

Cybercriminal groups are constantly evolving to find new ways to pilfer financial information, and the latest trick in their arsenal is to leverage the messaging app Telegram to their benefit. In what's a new tactic adopted by Magecart groups, the encrypted messaging service is being used to send stolen payment details from compromised websites back to the attackers. "For threat actors, this data exfiltration mechanism is efficient and doesn't require them to keep up infrastructure that could be taken down or blocked by defenders," Jérôme Segura of Malwarebytes said in a Monday analysis . "They can even receive a notification in real time for each new victim, helping them quickly monetize the stolen cards in underground markets." The TTP was first publicly documented by security researcher @AffableKraut in a Twitter thread last week using data from Dutch cybersecurity firm Sansec. Injecting e-skimmers on shopping websites by exploiting a known...

Threat actors have begun to use the Tox peer-to-peer instant messaging service as a command-and-control method, marking a shift from its earlier role as a contact method for ransomware negotiations. The findings from Uptycs, which analyzed an Executable and Linkable Format (ELF) artifact (" 72client ") that functions as a bot and can run scripts on the compromised host using the Tox protocol. Tox is a  serverless protocol  for online communications that offers end-to-end encryption (E2EE) protections by making use of the Networking and Cryptography library ( NaCl , pronounced "salt") for encryption and authentication. "The binary found in the wild is a stripped but dynamic executable, making decompilation easier," researchers Siddharth Sharma and Nischay Hedge  said . "The entire binary appears to be written in C, and has only  statically linked  the c-toxcore library." It's worth noting that c-toxcore is a  reference implementation  of...

Recently the Facebook-owned messaging app dropped its $1 annual subscription fee to make WhatsApp Free for Lifetime . Now, WhatsApp has plans to introduce a new feature that would allow its users to integrate their Facebook accounts with the most widely used messaging app. So far, the social media giant has been focusing on its own messaging platform, Messenger and both WhatsApp and Facebook have been working separately in terms of adding new features. WhatsApp to Share User Data With Facebook Android developer Javier Santos spotted a new feature in the latest beta build of WhatsApp, which indicates that soon you’ll start seeing some features interconnected between WhatsApp and Facebook. The feature (optional, for now), dubbed " Share my account info ," when selected will share your personal WhatsApp account information with Facebook in order "to improve your Facebook experience," according to the description. Although it's uncle...

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...

Popular Smartphone Messaging app  WhatsApp 's $19 billion acquisition by Social Network giant Facebook  made Headlines this week. While Some are applauding the move, and many other users are worried about WhatsApp’s future and their privacy after this acquisition. Why So Serious? WhatsApp currently having 450 million active users and processes 50 billion messages a day. Service charges a nominal service fee of $1/year, that means Facebook is buying at $42.22 per user. $19 Billion / 450 million users  = $42.22 per user These figures show ,  obviously future revenue from WhatsApp can’t cover the acquisition cost in the short or mid-term. " You can still count on absolutely no ads interrupting your communication. There would have been no partnership between our two companies if we had to compromise on the core principles that will always define our company, our vision and our product. " WhatsApp founder said in a  blo...

What would require crashing the wildly popular WhatsApp messaging application? Nearly 4000 Smileys . Yes, you can crash your friends'  WhatsApp , both WhatsApp Web and mobile application, by sending them not any specially crafted messages, but just Smileys. Indrajeet Bhuyan , an independent researcher, has reported The Hacker News a new bug in WhatsApp that could allow anyone to remotely crash most popular messaging app just by sending nearly 4000 emojis to the target user, thereby affecting up to 1 Billion users. Bhuyan is the same researcher who reported a very popular WhatsApp crash bug last year that required 2000 words ( 2kb in size ) message in the special character set to remotely crash Whatsapp messenger app. After this discovery, the company patched the bug by setting up the limits of characters in WhatsApp text messages, but unfortunately, it failed to set up limits for smileys send via WhatsApp. "In WhatsApp Web, Whatsapp allows 65500-660...

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 Culprit However, this strange behavior was not exhibited on every device. Only W...

Germany's Federal Office for the Protection of the Constitution (aka Bundesamt für Verfassungsschutz or BfV) and Federal Office for Information Security (BSI) have issued a joint advisory warning of a malicious cyber campaign undertaken by a likely state-sponsored threat actor that involves carrying out phishing attacks over the Signal messaging app. "The focus is on high-ranking targets in politics, the military, and diplomacy, as well as investigative journalists in Germany and Europe," the agencies said . "Unauthorized access to messenger accounts not only allows access to confidential private communications but also potentially compromises entire networks." A noteworthy aspect of the campaign is that it does not involve the distribution of malware or the exploitation of any security vulnerability in the privacy-focused messaging platform. Rather, the end goal is to weaponize its legitimate features to obtain covert access to a victim's chats, along wi...
