Demonstrators gathered in Warsaw on 26 September to protest the European Parliament's 'Chat Control 1.0' legislation, which would require messaging platforms to scan private communications, including encrypted ones, for illegal content. Critics argue the measure undermines privacy and encryption, while supporters say it is needed to protect children. Protests against the proposal have been held across several European cities.

A user associated with Digitalcourage, a German digital rights organisation, has published a personal IT privacy checklist dated October 2026. The encrypted document covers topics including chat control, surveillance, messaging apps, Linux, Windows, Microsoft, and F-Droid, and is tagged with privacy and media literacy hashtags. It offers practical guidance for people seeking to protect their data on smartphones and computers.

An encrypted Napoleonic-era military briefing, left unread for 217 years, has been decoded and published in a detailed writeup. The letter was addressed to Marshal Marmont, a French commander of the period. The decoding sheds light on wartime correspondence practices of the era, and the writeup has drawn attention among readers interested in cryptography and military history.

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.
