Windows Device IDs, Router Backdoors, and AI Payment Tricks: This Week in Cybersecurity

This week’s cybersecurity news centers on Windows’ new Global Device ID that can be tied to user activity, raising privacy concerns as Windows’ market share declines; researchers also found a hard-coded backdoor in Tenda router firmware with no available fix, prompting recommendations to disable remote management or replace the router. Other highlights include a Reddit/Discord account-hijacking scam, a US government payout (around $1M) to the Kairos data-extortion group with disputed outcomes, and prompt-injection attacks that trick AI agents into making crypto payments across multiple large-language models.
