Microsoft has issued a fix for a copy-and-paste failure affecting some Excel 2016 users following a recent security update. This comes as multiple cybersecurity threats emerge, including phishing attacks impersonating Signal support, zero-day exploits targeting on-premise SharePoint servers, and increased surveillance technology in China. Simultaneously, open-source software is gaining traction, with Switzerland exploring a Microsoft 365 alternative and KDE unveiling an AI-native desktop proposal. Several acquisitions and shifts in the tech landscape are also underway, including EQT’s purchase of a majority share in Acronis, Shopify’s support for Tailwind, and Canonical phasing out legacy chat channels.
