When Nations Hijack the Internet: A Deep Dive into State-Scale BGP Attacks and the Quantum Threat Ahead

Read about the internet’s Border Gateway Protocol (BGP)—built on an outdated trust model—enables state-level actors to reroute traffic for surveillance or disruption. The post highlights major campaigns by China and Russia, reviews historic cases (like Pakistan’s 2008 YouTube outage), and examines the spike in hijacks through 2024. It then explores how emerging quantum computing capabilities could magnify these threats by breaking current cryptography when traffic is intercepted.

Understanding Harvest Now, Decrypt Later Attacks: The Silent Threat to Your Data Security

A concise overview of “Harvest Now, Decrypt Later” (HNDL) attacks, explaining how adversaries collect and store encrypted data today with the intention of decrypting it once quantum computers become powerful enough. It breaks down the three phases of an HNDL attack—harvest, storage, and decrypt—highlights which encryption methods and industries are most at risk, and surveys real‐world evidence that these attacks have already begun. The post then outlines the urgency of adopting post‐quantum cryptography (PQC) standards, offers immediate protective measures (like transitioning to AES‐256 and implementing perfect forward secrecy), and provides strategic guidance for building long‐term crypto‐agility.
