### 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.

### Metadata
|
||||
|
||||
|
||||
[Image metadata](http://regex.info/exif.cgi)
|
||||
|
||||
- To find information inside a picture, we can use package [pnginfo] or [pngcheck].
|
||||
|
||||
- If we need [base64 decoding] (for example a PGP key with a picture).
|
||||
|
||||
- Weird pieces of bytes may need to be XORed.
|
||||
|
||||
- If we have a decrypted message and a key:
|
||||
1. Import the private key to use it to decrypt the message with ```gpg --allow-secret-key-import --import private.key```
|
||||
2. Decrypt with ```gpg --decrypt message.pgp```.

#### When we have a Website/IP Address:
|
||||
|
||||
- Try to add folders to the domain, such as http://csaw2014.website.com or http://key.website.com.
|
||||
|
||||
- We brute force the subdomains, for example, with [subbrute.py]. This tool performs multi-threaded DNS lookups to a configurable list of DNS resolvers, searching through a list of possible subdomains.
|
||||
|
||||
- Use the command ```dig``` or ```ping``` in Linux to find the IP address of the website.
|
||||
|
||||
- *wgetting* the entire website with something like ```wget -e robots=off --tries=40 -r -H -l 4 <WEBSITE>```.
|
||||
|
||||
- Check the *robot.txt* file for hidden folders.
|
||||
|
||||
- Inspect the DOM using the browser's developer tools to look for HTML comments (plain view-source won't work when the content is loaded through Ajax).
