## Footprinting and Reconnaissance
|
||
|
|
|
||
|
|
Footprinting or Reconnaissance is the process of gathering information about the target before an attack is carried out by a hacker.In a footprinting phase, the hacker will try to collect the maximum amount of information he can about the target which can be useful in an attack such as:

|
|
|
||
|
|
1. Identifying the operating system
|
||
|
|
2. Scanning ports to detect open ones for exploitation
|
||
|
|
3. WHOIS queries used to know about registrar information of a particular service.
|
||
|
|
4. Crawling the web to know more about the target.
|
||
|
|
5. Collecting phone numbers,email addresses,employee information & other insider information.
|
||
|
|
|
