+### Recon
+
+
+
+#### Searching the Internets
+
+The recon problems usually give you someone/something's name and a task or a hint to find some specific information about it. So the first thing is of course google it.
+
+Google anything using keywords such as ```filetype:cgi inurl:cgi-bin```
+
+
+#### In addition we can look at:
+
+- Facebook, Twitter, Linkedin, Google+, reddit,  /r/netsec.
+- IRC: with **/whois **.
+- [namechk] 
+- Github: check in the commit history.
+
