Urgency of Transitioning to Post-Quantum Cryptography Highlighted by New Open-Source Tool

The video addresses the urgency of transitioning to post-quantum cryptography due to the emerging threat of 'harvest now, decrypt later' (HNDL) attacks, where adversaries collect encrypted data today to decrypt it later using quantum computers. Aman Arora, co-founder and CTO of Qubit AC and a Black Hat USA 2026 Arsenal presenter, highlights that sensitive data like health records, financial information, and intellectual property are already at risk. He introduces AC Scanner, a free open-source tool designed to inventory and prioritize quantum-vulnerable cryptographic infrastructure by scanning TLS endpoints and SSH services in a single pass. The tool maps cryptographic exposure from discovery to a dashboard, serving as an initial defense against HNDL. Arora developed the tool after receiving Facebook scholarships to attend Black Hat in 2018 and 2019, emphasizing its community-driven improvement through feedback. The presentation underscores that quantum-resistant cryptography must be adopted proactively before quantum computers become widely available.
