The messaging app ArcaneChat is promoting itself as a more private alternative to Telegram, saying that unlike Telegram's opt-in secret chats, all its conversations — including groups and channels — are encrypted by default. It also highlights that it requires no phone number and claims to avoid spam and scammers, targeting users in Europe seeking more autonomy on Android.

New analysis claims the cost of a quantum attack on Bitcoin's cryptography has been halved, with an estimate of 1,151 qubits now cited for 2026. The revised figure suggests quantum computers capable of breaking Bitcoin's encryption may arrive sooner or cheaper than previously assumed, reviving debate about how urgently the network should adopt quantum-resistant safeguards.

WhatsApp is launching new tools designed to help parents guide teenagers in the app. The company stresses that private messages remain end-to-end protected despite the added oversight features, which include parental controls on Android and iOS and relate to Meta AI. The announcement draws attention to the balance between child safety and message privacy.

Cloudflare said Tuesday it plans to issue quantum-proof TLS certificates, positioning itself among the first certificate authorities to adopt cryptography designed to withstand attacks from future quantum computers. The move is seen as an early step toward protecting encrypted web traffic from 'harvest now, decrypt later' threats, and security watchers are weighing how quickly the wider industry will follow suit.

An Engadget report says law enforcement may have new methods to extract data from locked iPhones, raising fresh concerns over device security and user privacy. The story is being shared and discussed on social media, with readers noting it can be read without a paywall or JavaScript.

A security-focused account is highlighting how user information is protected: passwords are hashed, sensitive information is encrypted at rest, and data is not shared with any AI model. The message stresses that security is not only about tools but about how information is handled, and invites readers to learn more and sign up.

Ecuadorian immigration authorities have ordered the deportation of Swedish programmer and digital-rights activist Ola Bini. Bini, who has been living in Ecuador and was previously detained in a high-profile case linked to Julian Assange's stay in the Ecuadorian embassy, is known for his work on encryption and privacy. The order is drawing attention from digital-rights advocates watching how Ecuador handles the expulsion.

Apple has pulled Bitchat, an offline Bluetooth mesh messaging app with end-to-end encryption that works without internet, from India's App Store. The company says the removal followed a demand from the Ministry of Electronics and Information Technology under Section 69A of the IT Act, which allows blocking of content in the interest of national security. Security and privacy observers are questioning the takedown of an app designed for censorship-resistant communication.

Cybersecurity commentators are highlighting ransomware-resistant cloud storage as a key tool for business continuity. The discussion focuses on immutable object storage, which prevents attackers from altering or deleting backups, ensuring companies can restore data after an attack. Advocates argue that as ransomware incidents keep rising, protecting backup copies has become essential rather than optional for organisations of all sizes.

An explanation of public-key cryptography is circulating, using a padlock analogy: to receive a private message, you share an open padlock (your public key) while keeping the key (your private key). Anyone can lock a message with the padlock, but only your private key can open it, so intermediaries cannot read it.

A bipartisan group of senators has introduced the Quantum-GUARD Act, a bill designed to shield the US electric grid from future quantum computing attacks. The legislation would direct FERC to assess quantum-related cybersecurity risks across the energy sector and encourage adoption of post-quantum cryptography. Supporters argue 'Q-Day', the moment quantum computers can break current encryption, demands preparation now.

A question on the German Ubuntu users forum about playing Blu-ray discs with VLC media player is circulating among Linux users. VLC can play Blu-rays, but encrypted commercial discs typically require additional libraries such as libaacs and a keys database, which is why users frequently seek help with the setup on Linux distributions.

Thielix, described as an encrypted take on the Key of Solomon, has been released in hardcover and ebook, with signed copies on backorder and editions also sold through Amazon. The book mixes grimoire tradition, sigils and goetia with a puzzle element, drawing interest from occult and hyperstition communities following its launch.

A Linux user is asking how to transfer a session from one computer, where /home/session is not encrypted, to another machine where the same directory is encrypted, aiming to keep all personal configurations intact. The question, shared openly with the hashtag hints on migration, has drawn responses from other users offering methods for the move.

Open-source cryptographic libraries are being highlighted as a key resource for digital investigations and cybersecurity work. The topic sits at the intersection of OSINT, cybercrime research and AI-assisted analysis, with commentators framing accessible crypto tooling as important for online investigators examining encrypted material. Interest reflects broader debate about how open security tools are used by both defenders and criminals.

Gizmodo reports that law enforcement may have discovered a method to circumvent one of Apple's toughest iPhone security protections, a development with major implications for privacy and criminal investigations. If accurate, it would give police new access to data on locked devices, reigniting the debate between tech companies' encryption safeguards and investigators' demands for access.

The US National Security Agency has released a primer on post-quantum cryptography, explaining encryption methods designed to resist attacks by future quantum computers. The guidance comes as governments and companies race to migrate from algorithms that quantum machines could eventually break, amid growing concern over 'harvest now, decrypt later' threats to sensitive data.

Swiss-linked satellite constellation operator WISeSat.Space has completed its business combination with Columbus Acquisition Corporation, taking the space technology company public via a SPAC merger.

Further details on valuation and listing venue were not included in the announcement.

Reports suggest GrayKey, the forensic device used by law enforcement to unlock iPhones, may be able to bypass the automatic inactivity reboot that Apple introduced to protect devices from unauthorized access. The inactivity reboot was designed to lock down an iPhone's data after a period of non-use, complicating forensic extraction. If confirmed, the capability would reignite debate over police access to encrypted devices and the strength of Apple's security protections.

Shor's algorithm, developed in 1994 by American mathematician Peter Shor, is a quantum algorithm for finding the prime factors of an integer. Its theoretical power threatens widely used encryption based on factoring difficulty, and its existence has prompted a global shift toward post-quantum cryptography as researchers and governments prepare for future quantum computers.

Reports suggest law enforcement may have identified a method to keep iPhones seized during investigations accessible, rather than locked. The development touches on the long-running dispute between police and Apple over device encryption and access to evidence. Details of the method remain unconfirmed, and the claim has prompted renewed debate about privacy versus investigative needs.

WhatsApp messages and calls are end-to-end encrypted by default, but privacy commentators are highlighting important exceptions. Backups, metadata, and conversations with businesses may not receive the same protection, meaning parts of users' activity can still be accessible. Security experts are urging people to understand these limits before assuming all their WhatsApp communication is fully private.
