Course description
Passive intelligence gathering is a key part of any penetration test or ethical hack. This course explores the why and how of passive intelligence gathering in four videos, covering the goals of the intelligence-gathering phase, first- and third-party sources of information, Regional Internet Registries (RIRs), Google hacking, tools and more, as well as specific units on intelligence gathering through the investigation of DNS and SNMP. Remember: knowledge is power, and knowledge they don’t know you have is even better.
