Ransomware in your CPU – PSW #874

This episode covers recent security news including Android Lockdown Mode, vulnerabilities in routers and firmware, and tech from the latest firmware exploits to AI-powered reverse engineering. The hosts discuss the evolving landscape of cybersecurity threats, vulnerabilities in hardware and software, and the importance of resilient infrastructure and standards in the industry.

Keypoints :

  • Android introduces Lockdown Mode, enhancing device security against targeted threats like Pegasus.
  • Vulnerabilities found in legacy routers (e.g., Linksys, Cisco) expose millions to hacking, with attackers hijacking devices as proxies and botnets.
  • The CVE program has a new foundation to ensure vulnerability tracking remains independent and trustworthy amid funding concerns.
  • Firmware and microcode updates, including for Intel and AMD CPUs, are critical to defend against advanced hardware-based exploits like Spectre and speculative execution flaws.
  • Reverse engineering efforts reveal that firmware and hardware, such as Starlink gateways and routers, often lack encryption, making them susceptible to exploits.
  • Advanced threats like ransomware now target embedded devices and even CPU firmware through novel methods, raising concerns over hardware-level compromises.
  • The culture of rapid development in tech companies and the use of AI for coding contribute to increased security risks due to technical debt and poor design practices.
