What You Should Know About Jack Dorsey’s New Messaging App Bitchat

Jack Dorsey launched an open-source messaging app called Bitchat Mesh, or Bitchat, on July 28 through Apple's App Store. The app utilizes Bluetooth for data transmission instead of traditional internet connections and does not use contacts or phone numbers for connectivity, instead forming a Bluetooth mesh network among nearby devices. Each device acts as both a client and server, allowing for communication within the network, which is limited to those in proximity. Users can see the number of connected devices and send private messages, while main chat messages are visible to all within the network. Bitchat includes features like blocking users and sending playful notifications. Despite being open-source, the app has not undergone a third-party security audit, and users have been cautioned about potential vulnerabilities. Dorsey implemented the Noise Protocol Framework for end-to-end encryption but advised against using the app for production purposes until it receives an external security review.

Beware – Iran-linked fake VPN apps found to spy on Android users

Researchers have identified a new spyware campaign targeting Iranian users of Android VPN applications, specifically a revamped version of DCHSpy, which disguises itself as legitimate VPN services like Starlink. This campaign began shortly after the Israel-Iran conflict and coincided with increased VPN usage among Iranians facing internet restrictions. DCHSpy can collect sensitive user data, including WhatsApp messages, contacts, SMS, files, location information, call logs, and has the ability to record audio and capture images. The spyware is maintained by the hacking group MuddyWater, linked to Iran's Ministry of Intelligence and Security, and has been enhanced with new functionalities. Malicious VPN services EarthVPN and ComodoVPN are being used to spread the malware, following the previous use of HideVPN. Experts warn that hackers are distributing malicious APKs through trusted platforms like Telegram, increasing risks for Iranian citizens. Security analyst Azam Jangrevi advises caution when downloading apps, recommending verified app stores and mobile security solutions to detect threats like DCHSpy. For high-risk professionals, she suggests using hardware-based security keys and vetted encrypted messaging applications.

I Tried Signal, Telegram and WhatsApp, and This Is the One I’d Recommend

Telegram retains data necessary for its operations, including metadata like IP addresses. In 2024, the company updated its privacy policy to clarify that it can disclose IP addresses and phone numbers of rule violators to law enforcement upon valid legal requests. This resulted in Telegram fulfilling 900 information requests from U.S. authorities in 2024, affecting 2,253 individuals. Telegram has experienced data breaches, including a 2020 incident where 42 million Iranian users had their data compromised and a 2019 vulnerability exploited by Chinese agencies affecting protestor identities in Hong Kong. The platform allows users to create public channels for sharing content, but these channels are not end-to-end encrypted. Telegram offers secret chats that are end-to-end encrypted, but they are limited to the device of origin. The app allows for automatic message deletion, with a minimum interval of one day, and features a self-destruct option for accounts after a period of inactivity. Telegram's client applications are open-source, while its server-side code is closed-source. The company operates on a freemium model, offering a paid tier for enhanced features. Telegram is available for free download on the Apple App Store and Google Play Store.

Jack Dorsey Launches Bitchat: All About The Messaging App That Works Without Internet

Jack Dorsey has introduced a beta version of a messaging app called Bitchat, which operates without an internet connection by utilizing Bluetooth technology for encrypted messaging between nearby devices. Bitchat functions on a peer-to-peer basis through Bluetooth mesh networks, allowing users to send encrypted messages without reliance on central servers or personal identifiers. The app enables local Bluetooth groups for message sharing and features group chats called "rooms," which can be secured with passwords. Messages are stored on users' devices and disappear by default. Bitchat draws inspiration from Bluetooth applications used during the 2019 Hong Kong protests and aims to provide communication during internet shutdowns. All 10,000 beta testing slots were filled quickly, and the app is currently under review for an official launch.

Vietnam to block messaging app Telegram over ‘anti-state’ contents

The Vietnamese government has instructed telecommunications companies to block the Telegram messaging app, citing security concerns and the dissemination of "anti-state" content. This directive was issued by the Telecommunications Department and requires service providers to report compliance by June 2. A document from the Ministry of Public Security indicated that 68% of approximately 9,600 Telegram channels and groups in Vietnam were classified as “bad and toxic,” involved in activities such as anti-state messaging, fraud, and drug trafficking. The government referenced Article 9 of the Telecommunications Law and Decree 147 to justify the ban, claiming Telegram had not complied with regulations. Despite the ban, Telegram remained accessible in Vietnam as of the report date. Telegram expressed surprise at the government's actions and confirmed it is responding to legal requests from Vietnam.

Signal will block Microsoft Recall from snooping on your texts

Encrypted messaging platform Signal is enhancing its Windows application with a feature called Screen Security, which prevents screenshots of messages while the app is in use. The application is flagged as protected by Digital Rights Management (DRM), ensuring that DRM content cannot be recorded in screenshots on Windows devices. Screen Security is activated by default but can be disabled by users if needed. Signal hopes that AI developers will consider the implications of their innovations more thoughtfully. The Recall feature in Windows 11, which allows users to record everything displayed on their screens, has faced privacy and security concerns, and skepticism remains about its readiness for widespread adoption.
