If you've got a USB drive or SD card that can't be formatted and to which you can't copy files, then take a look at our guide to removing write protection.

Sometimes you'll find that it's impossible to format, delete or copy new files to an SD card or USB flash drive. Windows will tell you that it is write protected, even though there is no 'lock' switch or – if there is – you've made sure the switch is set correctly to allow files to be written to the drive.

But just in case this switch is news to you, it is well worth checking that your device has the switch set to 'unlocked'. When set to 'locked' you won't be able to copy any new files on to the memory card or USB stick, and it also stops you from accidentally formatting it.

You'll still be able to view files which are already stored on the drive, but you can't delete them (they sometimes seem to delete OK, but the next time you check, there they are again!).

ut if this isn't the problem, you might still be able to fix things and continue to use your USB flash drive or SD card – we'll explain how.

Unfortunately, in some cases the device may be corrupt or physically broken and no tricks or software will make it work again. The only solution in this case is to buy a new drive. And if you're just trying to get back lost data, see our guide on How to recover deleted filed for free.

In any version of Windows from XP onwards, run Regedit.exe.

If you're not sure how to find it, searching 'regedit' in the Start menu will usually show the program at the top of the list.

It's a bit like File Explorer, so use the pane on the left to navigate to the following key:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

Note: if you can't find StorageDevicePolicies, see the next step.

Double-click on the WriteProtect value in the right-hand pane. You can now change the Value data from 1 to 0. Then click OK to save the change. Close Regedit and restart your computer. Connect your USB drive again and, with a bit of luck, you should find it is no longer write protected.

You can now continue to use the drive, but it's worth copying off any files you want to keep and then formatting it by right-clicking on it in the list of drives in File Explorer and choosing Format.

StorageDevicePolicies

If you can't find StorageDevicePolicies, you can create it by right-clicking in the white space in the 'Control' folder and choosing New -> Key and entering the name StorageDevicePolicies.

Now double-click on the new key (it will show as a folder) and right-click once again in the white space and choose New -> DWORD. Name this WriteProtect and set its value to 0. Click OK, exit Regedit and reboot your computer.

If this method doesn't work, go to the next step.

Diskpart

With your USB drive or memory card attached to your computer, launch a command prompt. You can do this by searching for cmd.exe or 'Command Prompt' in the Start menu.

Note: you may need to run cmd.exe with administrator privileges if you see an "access is denied" message. To do this, right-click on Command Prompt in the Start menu and choose 'Run as administrator' from the menu that appears.

If you have Windows 10, simply right-click on the Start button (bottom left of the screen) and choose Command Prompt (admin).

Now, at the prompt, type the following and press Enter after each command:

diskpart
list disk
select disk x (where x is the number of your non-working drive – use the capacity to work out which one it is)
attributes disk clear readonly
clean
create partition primary
format fs=fat32 (you can swap fat32 for ntfs if you only need to use the drive with Windows computers)
exit

That's it. Your drive should now work as normal in File Explorer. If it doesn't, it's bad news and there's nothing more to be done. Your stick or memory card is scrap and fit only for the bin. But the good news is that storage is cheap.

You might have harvested many things upto now but what we are going to harvest today is something bad :)

Requirements:

A Linux box (I'm using Kali Linux)
theharvester program (already available in Kali Linux)

So what does theharvester harvest? Well it harvests email addresses. theharvester is an Information gathering tool. If you want a list of emails to spam you can get that easily from theharvester tool and go on Spamming (I'm joking its illegal). It's a security tool that helps you in pentesting an organization (as always it can be used for evil as well). You can gather emails from an organization and look for potential victims to attack or use brute-force techniques to get their passwords or Social Engineer them into doing something that will let you compromise some or all systems in the organization. Uhh there are so many things that you can do when you have access to someone's email address.

OK stop talking and start doing.

Fire up a terminal in your kali box and type this command:

theharvester -d hotmail.com -l 50 -b google

In a small amount of time you'll see your terminal flooded with 200 hotmail.com email address. What does this command mean?

theharvester is the tool name that we are using
-d <domain_name> specifies the domain (or website) who's email addresses we're looking for, in our case it was hotmail.com
-l <number> specifies the number of results that we want in the output, I limited it to 50
-b <source> specifies the source on which to look for email addresses, I specified google as the source

Besides google we can specify any of the follow as source:
google, googleCSE, bing, bingapi, pgp, linkedin, google-profiles, people123, jigsaw, twitter, googleplus, all
Here the last entry all means look in every available source.

Let's say you wanted to look in every available source they you should specify the following command:

theharvester -d hotmail.com -b all

-f is another great flag which can be utilized to save the output in case we want to SPAM them later (just kidding) or for other reasons (I'm thinking positive). -f flag saves the result in html or xml format. Let's do just that:

theharvester -d gmail.com -l 50 -b google -f emailaddresses.html

here -f flag is followed by the location where we want to store the file and the name of file, in our case we stored it in our pwd (present working directory) with the name emailaddresses.html.

Above picture shows an html output generated by harvester.

That's it for this tutorial hope to see you next time!

What is the process of hacking or phases of hacking?
Hacking is broken up into six phases:The more you get close to all phases,the more stealth will be your attack.

1-Reconnaissance-This is the primary phase of hacking where hacker tries to collect as much as information as possible about the target.It includes identifying the target,domain name registration records of the target, mail server records,DNS records.The tools that are widely used in the process is NMAP,Hping,Maltego, and Google Dorks.

2-Scanning-This makes up the base of hacking! This is where planning for attack actually begins! The tools used in this process are Nessus,Nexpose,and NMAP. After reconnaissance the attacker scans the target for services running,open ports,firewall detection,finding out vulnerabilities,operating system detection.

3-Gaining Access-In this process the attacker executes the attack based on vulnerabilities which were identified during scanning! After the successful, he get access to the target network or enter in to the system.The primary tools that is used in this process is Metasploit.

4-Maintaining Access-It is the process where the hacker has already gained access in to a system. After gaining access the hacker, the hacker installs some backdoors in order to enter in to the system when he needs access in this owned system in future. Metasploit is the preffered toll in this process.

5-Clearning track or Covering track-To avoid getting traced and caught,hacker clears all the tracks by clearing all kinds of logs and deleted the uploaded backdoor and anything in this process related stuff which may later reflect his presence!

6-Reporting-Reporting is the last step of finishing the ethical hacking process.Here the Ethical Hacker compiles a report with his findings and the job that was done such as the tools used,the success rate,vulnerabilities found,and the exploit process.
