covert channels
About this tag
Covert channels are a recurring security concern in discussions on WindowsForum.com, particularly in the context of modern computing threats. Recent threads highlight how agentic AI browsers can be exploited as covert exfiltration channels, enabling credential theft and privacy erosion through hidden data transfers. Another thread examines SmartAttack, a technique where smartwatches create covert channels to exfiltrate data from air-gapped systems, bypassing traditional network isolation. These examples underscore the evolving nature of covert channels, which extend beyond classic network-based methods to include side-channel attacks via peripherals and AI-driven browser assistants. The tag covers research and analysis on how such channels are discovered, exploited, and mitigated in enterprise and security-focused environments.
Agentic AI browsers — the biggest breakthrough of 2025 — have lurched from promise to peril in less than a year, as independent research led by Brave has exposed systemic vulnerabilities that can turn helpful assistants into covert exfiltration channels, opening new paths for credential theft...
For decades, the fortress-like defense of air-gapped computers—those completely disconnected from external networks—has stood as a cornerstone of security in top-secret governmental agencies, defense contractors, and industries with critical infrastructure. The guiding philosophy was simple: if...
