Hello,

before we start with Ethical hacking & cybersecurity stuff.  we need to build our lab and 1st we need to install kali linux on virtual box lab environment.

Here is my Your tube channel Link for :

Dear User,

if you are working with cybersecurity or as Ethical hacking stuff, its important to Hide your presense on internet and stay 100% Anonymous.

Here are 3 ways to Hide your presense on internet.

1. By using open VPN

2. Tor proxy

3. free proxy chain

Lets learn each one by one.

Open VPN :-

you can download open vpn from many free websites like https://spys.one/en/ or Openvpnbook.com ..just google and you will find many. its important to hide your public ip over internet with browsing darkweb or other cubersecurity related stuff and secure yourself. many get hacked by not following small things and face problems.

1. Download open VPN connection details from site

2. connect to open vpn 

3. check your public ip and it should be differnet than your original public ip.

4. sometime it will not work and problem could be related to your DNS Server so change the DNs server to free DNS server and try again.

Tor Proxy :

1. Install tor on Kali linux

2. apt install tor

3. check service is running for Tor

service tor status

4. Edit proxychain file

5. connect via proaxy chain and check your public . it will change to differnet one and location.

Proxy Chain:

Stay 100% anonymous from internet via using proxy chain.

its imposible for anyone to track you down by using proxy chain

Connecting via Tor proaxy + another proxy + another proxy + another proaxy ..and so on.

1. Down load free proxy list from https://github.com/amitkumaripec/PROXY-List or https://free-proxy-list.net

2. find the working proxy and verify it from https://hide.mn/en/proxy-checker/

3. Edit the proxychain or proxychain4 file

4. Enable dynamic proxy & disable static one

5. Enable proxy DNS

6. Add the proxy in list as give example in file 

7. start proxy chain and check your public ip

Note: The goal of the article is to teach you so how you can hide yourself when browsing dark web or doing any cybersecurity stuff. using any of tips illegally if your own responsibility and could have consequences

Hello,

Netdiscover is Active / Passive reconnaissance tool . its used to discover devices in your wireless & wired network.

Example :

Scan all the available devices in network under this range.

#netdiscover -r 10.0.3.0/24 

search for only 10 devices then add switch

#netdiscover -r 10.0.3.0/24 -c 10

Have many network card in your machine and want to use specific nic for discovery 

#netdiscover -i eth0 -r 10.0.3.0/24 -c 10 (is not it simple?)

here is another example 

#netdiscover -i eth0 -r 10.0.3.0/24 -c 10 -s 5

want to read more about netdiscover.  

run the following command in kali linux

#man netdiscover

Enjoy excercise video for same :

Thanks

Its very important to understand the hacker methodology and build security on these levels in order to protect your system or corporate network.

Many Ethical hacker names these steps with different words but overall background concept it almost same.

if you are a ethical hacker then you need to write a contract with company before performing any penetrate testing. its does not matter what level of testing you are doing but it has to be officially approved by authorised person. (wireless penetrate testing,webserver, network , System or application).

Phases of Ethichal Hacking

1. Reconnaissance : In this phase of analysis , Ethical hacker gather information about system in passive mode without giving any alert to System .

2. Scanning : Ethical hacker perform active scanning to system by using tool like Nmap (free tool), Nessus(its paid tool). there is high chance that you will alert system administrator.

3. Identify Volunerability: identify the application version or Os version used in system and find the volunerability mentioned in Rapid7 or exploitdb.com database for more details and how to exploit system

4. Gain Access : Get access to system by exploiting the open volunerabilty of system. open session with target device and get access to files, folders and sensitive informations.

5. Maintain access : this is very important phase , dangerous hacker mostly extend their access to multiple system in this phase and maintain it. it may be one system get fixed but their spread access into network system so loosing one access to system does not much affect them. being a ethical hacker its reposbilities to close these gaps for black hat hackers.

6. Report : In this final phase , Ethical hacker submit a report back to company so they can fix the risk areas.

once all the testing is completed , ethical hacker must clear all the logs and traces of penetrate testing from performed system.
