Weekly Cyber News Rollup, December 5th, 2025

This is your weekly cyber news roll-up for the week ending December 5th, 2025. Holiday shopping dominates the threat landscape, with industrial scale fake Christmas and Cyber Monday stores siphoning card data while a massive breach at Korean retail giant Coupang exposes tens of millions of shoppers. At the same time, attackers are burrowing into the software factory, from exposed secrets in cloud code repositories and malicious developer packages to tainted browser extensions that quietly spy on everyday work in customer relationship, finance, and human resources tools. Law enforcement’s takedown of a major crypto mixer shows real pressure on ransomware cash washing, even as mobile devices and airport Wi Fi remind leaders how fragile everyday access can be.Across the episode, you will hear how attackers exploit hurry, convenience, and shared platforms in very different settings, from North Korean software supply chain campaigns and steganography tools built for espionage, to vendor breaches at financial data providers and cross tenant flaws in cloud services. We explore how weak artificial intelligence governance and powerful low code workflows can be twisted into ransomware launchers, how fake ChatGPT style browsers steal passwords at scale, and why critical bugs in React based web stacks demand rapid attention from builders. Executives, security teams, engineers, and students all get practical context on where trust is eroding and which signals to watch in logs, workflows, and vendor relationships. This weekly roll-up is designed to help you decide what to act on first, and it is available at DailyCyber.news.
