Dec 19, 2024 Chinese researchers are inching closer to quantum computing breakthroughs, but modern encryption remains safe for now. A clever Russian group exploited nearby Wi-Fi for covert attacks, showcasing their tactics. A controversial startup is bricking its $800 emotional support robot, raising eyebrows about corporate ethics. Meanwhile, concerns about our emotional attachment to AI companions unfold, as companies might exploit these relationships. Additionally, security practices for Linux systems and the role of tools like AppArmor are discussed.

Episode notes
Quantum Computing Progress
- Chinese researchers are making progress with quantum computing, but haven't broken RSA or AES encryption.
- AES-256 is equivalent to cracking a 15,360-bit RSA key, making it far safer.
50-Bit Key Cracking
- In 2010, researchers cracked a 768-bit RSA key after 2.5 years with hundreds of computers.
- Cracking a 50-bit key with a quantum computer is like a toddler drawing a stick figure compared to Rembrandt.
Quantum-Resistant Encryption
- Consider quantum-resistant encryption if you need long-term confidentiality.
- Perfect Forward Secrecy (PFS) protects against future RSA key compromises, but not brute-force attacks.
