A recent mistake—where a journalist was accidentally added to a private Signal chat—has raised fresh concerns about officials using consumer messaging apps for sensitive discussions. While Signal offers strong encryption, CCS Insight’s Chief Analyst Ben Wood points out that "the greatest vulnerability in any technology remains human error." 

He also underlines a looming challenge: "Quantum computing could crack encryption, forcing a rethink of digital security."

In the latest episode of the MEF Podcast Series: Perspectives, host Riccardo Amati speaks with Ben about security, trust, and the impact of emerging technologies on encryption standards.

The conversation also explores how mobile messaging is evolving and what the future holds for platforms like WhatsApp, iMessage, and RCS.
