We started off with discussing the importance of knowing what we are doing here. There are basically three types of hackers in this community – Grey Hat, Black Hat and White Hat hackers. This is a training session for the future White Hat’s, aka Ethical Hackers! White hat hackers choose to use their powers for good rather than evil. They employ the same methods of hacking as black hats, with one exception- they do it with permission from the owner of the system first, which makes the process completely legal. White hat hackers perform penetration testing, test in-place security systems and perform vulnerability assessments for companies.

**Beware: We are not here for personal gains! Apart from this, Enjoy Hacking! :D **

ADVANCED LINUX

Then I started with basic to advanced linux commands that we’re gonna work with throughout this training session –

  • NOTE – You always have a handy manual if you want to know more about any command, inbuilt into Linux.

  • Usage

    • man <command> Eg- man chmod
    • ls –lra - Listing directory contents { long listing, all, reverse }
    • gedit – graphical text editor
    • nano/vim/vi -terminal text editor
    • echo “CONTENT” > file.txt
    • > is used to write/overwrite >> used to append to a file Eg- ifconfig > ip.txt

  • cat / tac / more / less - display contents of a file

  • head / tail - first and last 10 lines of the content of a file

  • nl – file with line number

  • find command

  • Recursive so it’ll literally search everywhere inside that directory

  • Find /dir_name –name - to search inside a specific directory  which <command_name> -tells us the location of the binary. It searches for the binaries in

  • “echo $PATH”  where is <cmnd_name> - It finds for the binaries anywhere, not only in the above locations  locate <file/command> - FASTER, uses a pre made database. NEW FILES CANNOT BE FOUND

INFO GATHERING

So do you know about IoT devices?

Basically these are very small computers embedded with electrical devices to form a smart device. Eg- Smart home stuff, cameras, etc

Now if you wanna control them, you generally use your phone, and these IoT devices are connected to your home router. The catch here is.. These devices then become connected to Internet UNSECURED. They are very tough to secure… think about it! Imagine you have to put a password to switch on your smart bulb -_-

The address to these devices can be found out easily on the internet with the help of Google Dorking or Shodan.

This is one of the few applications of Google Dorking. 0_EA62_VMXI5zNV8FS.png
