Quantum Computing Isn’t Just Coming for Bitcoin—It Threatens Messaging Apps Too

IBM researchers are collaborating with Signal and Threema to develop messaging systems resilient to quantum computing threats, prompted by concerns that quantum technology could compromise current encryption methods. IBM's report stresses the need to redesign messaging protocols in anticipation of potential quantum capabilities that could break existing encryption. Cryptography expert Ethan Heilman highlighted that encrypted messaging platforms face immediate risks from quantum threats, specifically through "store-and-forward attacks." Both Signal and Threema are enhancing their security measures; Signal is implementing upgrades like PQXDH and SPQR for post-quantum protection, while Threema is integrating the ML-KEM algorithm for quantum-safe encryption. Research indicated that adapting the Signal protocol for quantum safety may increase bandwidth requirements, necessitating a complete redesign for efficiency.

Arattai’s Unexpected Surge: Road Ahead for Zoho’s Messaging App, Hard Lessons From Past

Zoho's instant messaging application, 'Arattai,' has gained significant attention as a potential alternative to WhatsApp, particularly after endorsement from Union Minister Dharmendra Pradhan. Daily sign-ups increased from 3,000 to 350,000 within 72 hours, and Arattai now has over 1 million monthly active users. Most new users are from India, prompting Zoho to enhance its infrastructure to meet demand, although some users have faced issues like OTP delays. Zoho founder Sridhar Vembu indicated plans for a significant launch in November and discussions for messaging protocol standardization. Arattai evolved from Zoho Chat and aims to reflect India's unique needs. Challenges remain, as local platforms like Koo and Hike Messenger struggled to maintain user bases. Industry experts note that being an Indian product alone may not be enough to compete with established platforms. Arattai is focusing on user feedback, infrastructure, and plans to implement end-to-end encryption while avoiding advertising in its monetization strategy.

Photo appears to shows Mike Waltz using Signal-like app that can archive messages

White House Deputy Press Secretary Anna Kelly confirmed that the encrypted messaging application Signal is officially sanctioned for government use and installed on government-issued devices. The National Security Council has not commented on the related app, TeleMessage, which is derived from Signal and designed to help government entities comply with records retention laws. TeleMessage was founded in 1999, acquired by Smarsh in 2024, and has been involved in government contracts, including a .1 million contract with the Department of Homeland Security and FEMA that began in February 2023 and will conclude in August 2025. Tom Padgett, Smarsh’s president for enterprise business, stated that like Signal, messages sent through TeleMessage are encrypted, but the app does not address security issues raised by a recent incident involving Signal. The specifics of how government officials utilize TeleMessage remain unclear, and five cybersecurity experts admitted they were unfamiliar with the app prior to recent developments. TeleMessage licenses parts of its technology, including its encryption protocol, to other companies, but Signal clarified there is no formal agreement with TeleMessage and expressed concerns about the privacy and security of unofficial versions of their app.

Signal is ‘as safe as messaging apps get’, but not for national security

End-to-end encrypted messaging app Signal is recognized for its security features but is advised against for use by government officials discussing national security. A breach occurred when members of former President Donald Trump's national security team mistakenly included a journalist in a group chat sharing sensitive military information. Cybersecurity experts express concerns about the potential legal implications of using apps like Signal for classified communications, as it could violate the Espionage Act. High-ranking officials were involved in this incident, which exposed sensitive details, including air-strike targets and the identity of a CIA officer. Typically, government officials use Secure Compartmentalized Information Facilities (SCIFs) for classified information, and there are specific government-approved systems for transmitting such information that do not include Signal.

You Can Now Text Yourself via RCS on Google Messages (and You Should)

Google Messages has introduced a beta feature that allows users to send messages to themselves using RCS (Rich Communication Services), which provides advantages over SMS, such as the ability to send longer texts and high-resolution media without compression. However, RCS messages sent to oneself currently lack encryption. If the feature is active on a device, users can simply text themselves, or they may need to enroll in the Google Messages beta program. Self-messaging offers convenience and the ability to synchronize messages and media across devices, but users concerned about security may consider using encrypted platforms like Signal for sensitive information.

What is RCS messaging and why is it important?

RCS is a messaging protocol that is an upgrade over standard SMS text messaging, offering features such as sharing videos, GIFs, and location data, as well as encryption for secure messaging. It integrates seamlessly with phone contacts and does not require a separate app or sign-up. RCS requires support from both carriers and mobile devices, with over 55 carriers worldwide now supporting it. Despite its potential, RCS faces challenges such as fragmentation and slow adoption, leading many users to continue using third-party messaging apps.

DOJ claims green bubbles are an issue in iPhone monopoly suit | TechCrunch

The United States Department of Justice is focusing on Apple's messaging protocols, particularly the distinction between iMessage on iPhones and SMS on Android devices. The DOJ highlights how iMessage can act as a deterrent for iPhone users considering switching to Android, as it offers features like end-to-end encryption and group messaging that are not easily replicated on third-party apps. Apple has shown openness to incorporating Rich Communication Services (RCS) influenced by regulatory requirements in certain markets. The lawsuit underscores a broader interest in the interoperability and openness of digital ecosystems.
