Discuss the concept and merit of pivoting off domain information

  • Why pivot off domain names/URLs?
  • Pivot off registrant information
  • Pivot off Nameservers, Google Analytics IDs, Alexa codes, etc.

Case Study #1

  • Use www[.]caihongtangddos[.]cn as first pivot point within DomainTools Iris (This was a published DDoS platform from Cisco Talos from Aug 15th)
  • Pivot off contact name (梁甲福)
  • Pivot off 891246422@qq.com
  • Show additional DDOS infrastructure

Case Study #2

  • This case study is related to the ransomware Teslacrypt.
  • First, start ApateDNS on analysis machine
  • Execute sample and watch communications to free-stuff-here.netne.net
  • Pivot on free-stuff-here.netne.net in DomainTools Iris (off of Contact Name Kyriakos Kyriako)
  • Generate CSV file
  • Mention blocking or monitoring the other domains that show up proactively, as they are likely related infrastructure.
  • Take comli.com and pivot in Virustotal Intelligence looking for additional samples
  • Talk about proactively blocking hashes/comli.com, etc.
