Jack Dorsey launches Bitchat, a secure messaging app that doesn’t use the internet

Jack Dorsey, co-founder of Twitter, Bluesky, and Square, has introduced a private messaging application called Bitchat, which operates independently of traditional internet or cellular networks. Bitchat utilizes decentralized Bluetooth technology and end-to-end encryption for secure communication. It is based on Bluetooth Low Energy (BLE) mesh networks, extending the typical Bluetooth range from 100 meters to 300 meters. Developed with the help of an AI coding companion named Goose, Bitchat is described as a "weekend project." The app aims to provide resilient and private communication, but critics have raised security concerns about its authentication system. Dorsey has issued a disclaimer stating that Bitchat is a "work in progress" and has not undergone external security review, warning users against relying on its security until it is evaluated.

Signal blasts Microsoft over Recall privacy failings, as secure messaging app is forced to fudge a way of blocking the controversial Windows 11 feature

Signal has introduced a new feature in its Windows 11 application that blocks Microsoft's Recall functionality to enhance user privacy. This 'screen security' setting is activated by default for Windows 11 users and is part of Signal's efforts to protect shared content on its platform. Recall captures screenshots of user activity on Copilot+ PCs, which raised privacy concerns. While Microsoft has improved Recall, issues with its interaction with privacy-focused applications like Signal remain. The feature is specifically applicable to users with Copilot+ PCs equipped with a Neural Processing Unit (NPU). Users can disable the screen security setting through Signal Settings > Privacy > Screen security, with a warning about the privacy implications of doing so.

Signal controversy: Why the secure messaging app is all over the news

Signal is an end-to-end encrypted messaging application that distinguishes itself from competitors like Messenger and WhatsApp through its open-source technology and the use of the Signal protocol for encryption. It encrypts messages before they leave the sender's device, ensuring that only the intended recipient can read them. However, its security is tied to the user's device, and vulnerabilities such as weak passwords and unprotected devices can compromise message integrity. Despite its strong encryption, Signal may not meet the stringent security protocols required for sensitive government communications, particularly due to its message deletion feature and the lack of support for record-keeping. The app is considered secure for everyday users, but may not be suitable for high-stakes governmental communication. The rise in cyber threats underscores the need for secure communication channels, leading organizations to consider encrypted messaging solutions like Signal, while also evaluating alternatives within the encrypted messaging landscape.

Which is the most secure messaging app? Expert weighs in after U.S. war plan leak blunder

A significant intelligence breach occurred when Jeffrey Goldberg, editor-in-chief of The Atlantic, was inadvertently added to a sensitive Signal group chat that included discussions about U.S. military operations targeting Houthi rebels in Yemen, involving Vice President JD Vance and Defense Secretary Pete Hegseth. Senate Democratic Leader Chuck Schumer described it as "one of the most stunning breaches of military intelligence." Experts emphasized that the breach resulted from human error, not flaws in encryption technology. Signal is considered the gold standard for secure messaging due to its end-to-end encryption and lack of metadata collection. Other platforms like iMessage and WhatsApp have varying levels of security, with iMessage requiring both parties to use Apple devices for full protection, and WhatsApp collecting metadata. Telegram does not enable end-to-end encryption by default for standard messages. The incident highlights that even the most secure messaging applications cannot prevent breaches caused by human oversight.

What is Signal? The app where US officials accidentally shared war plans with a journalist

A group chat among top US officials on the secure messaging app Signal inadvertently included a journalist, raising concerns about the app's security and the protocols for its use by government officials. Signal is known for its end-to-end encryption, ensuring that only participants can access conversations, and it cannot comply with law enforcement requests for user data. During the Biden administration, officials were allowed to use Signal under strict instructions not to share classified information. The incident involving Trump administration officials, who mistakenly added a journalist to a chat about military operations, is being reviewed by the National Security Council.

Choosing the right secure messaging app for your organization

Liad Shnell, the Chief Technology Officer at Rakuten Viber, discussed key factors organizations should consider when selecting secure messaging applications. Important features include end-to-end encryption, global accessibility, integration capabilities, AI-driven extensibility, and privacy standards like SOC 2 Type 2 and GDPR compliance. To mitigate phishing and malware risks, users should exercise caution with links and verify sender identities. Leading platforms like Viber implement security measures, such as filtering messages from unknown senders and using algorithms to block suspicious activities. The SANS 2024 Security Awareness Report indicates that 89% of respondents view social engineering attacks as a primary concern, emphasizing the need for security awareness programs, clear communication policies, and AI-driven detection tools. Balancing usability and security is essential, with a focus on user experience through AI-driven automation and zero trust principles. Emerging trends include post-quantum cryptography and enhanced AI detection capabilities to maintain authenticity in conversations as technology evolves.

Is Telegram Safe? Secure Messaging App Explained

Telegram is a secure messaging platform that offers end-to-end encryption for video, text, and audio messages. The app employs this encryption by default for voice and video calls and in private chats known as Secret Chats. Despite its security features, Telegram has faced scrutiny for providing user information to authorities in the past. Recently, CEO Pavel Durov was arrested in France on charges related to crimes facilitated through the platform, including drug trafficking and online scams. The arrest has raised concerns about the platform's safety, but it is noted that it will not significantly affect the app's encryption. Prominent figures have expressed support for Durov, arguing that platform owners should not be held responsible for abuses of their services. Users are advised to remain vigilant against scams by being cautious of unsolicited messages, avoiding sharing sensitive information, and maintaining a skeptical mindset.
