What are two methods used by cybercriminals to mask DNS attacks? (Choose two.)

  • reflection
  • shadowing
  • domain generation algorithms
  • fast flux
  • tunneling

Explanation: Fast flux, double IP flux, and domain generation algorithms are used by cybercrimals to attack DNS servers and affect DNS services. Fast flux is a technique used to hide phishing and malware delivery sites behind a quickly-changing network of compromised DNS hosts (bots within botnets). The double IP flux technique rapidly changes the hostname to IP address mappings and the authoritative name server. Domain generation algorithms randomly generate domain names to be used as rendezvous points.
