Episode notes
New Quantum Algorithm Lowers Qubit Barrier
- Quantum threat models may shift quickly as new algorithms reduce qubit needs.
- The JVG algorithm claims breaking RSA/ECC with under 5,000 qubits by offloading more work to classical systems, needing independent verification.
Exclude Surveillance Use When Contracting AI
- Limit AI access explicitly when contracting with sensitive agencies to reduce surveillance risks.
- OpenAI moved to exclude NSA use and ban deliberate tracking or monitoring of U.S. persons in its Pentagon terms.
Tax Agency Leaked Seed Phrase and Lost Millions
- South Korea's National Tax Service posted photos of seized crypto that included a hardware wallet seed phrase.
- The exposed seed let attackers drain about $4.8M in PRTG tokens from the wallet within a day.
