Subdomains are a mysterious part of the attack surface, as they represent additional entry points or potential targets that can be exploited to gain access to a network or system. https://txgate.io/images/smilies/read.gif
Why look for subdomains?
- They are often not as heavily guarded or protected.
- They effectively expand the attack surface.
- They can serve multiple functions, services, etc.
- They are unknown
