SN 1049: DNS Cache Poisoning Returns - Ransomware Payments Plummet

Listen Later

Just when you thought DNS cache poisoning was a thing of the past, Steve and Leo reveal why this 17-year-old bug is making a dramatic comeback—and why most DNS resolvers still can't manage high-quality random numbers after all this time.

  • The unsuspected sucking power of a Linux-based robot vacuum.
  • Russia to follow China's vulnerability reporting laws.
  • A pair of Scattered Spider UK teen hackers arrested.
  • Facebook,Instagram and TikTok violating the EU's DSA.
  • Microsoft Teams bringing user WiFi tracking bypolicy.
  • You backed up. That's great. Did you test that backup?
  • Coveware reports all-time lowransomware payment rate.
  • Ransomware negotiator reports how the bad guys get in.
  • Lots of listener thoughts and feedback about NIST passwords.
  • And against all reason and begging credulity, it seems we still haven't managed to put high-quality random number generators into our DNS resolvers.
