It's not clear what value hackers might find in perusing the chats of WhatsApp users, but that's small comfort to those who'd rather not expose their private conversations. An Android developer presented a proof of concept showing how the deed could be done, but there's no reason to believe that any thieves have penetrated the WhatsApp vault. It could mean a snag in Facebook's acquisition deal.

An Android developer's disclosure that it's possible to hack into the WhatsApp database and read the text of the chats from another application could be a big headache for Facebook, which has agreed to purchase the app for US$19 billion.

Break Administrator Password In XP

Password cracking is the process of recovering passwords from data that
has been stored in or transmitted by a computer system. A common
approach is to repeatedly try guesses for the password. The purpose of
password cracking might be to help a user recover a forgotten password
(though installing an entirely new password is less of a security risk, but
involves system administration privileges), to gain unauthorized access to a
system, or as a preventive measure by system administrators to check for
easily crack able passwords.

How to get files removed by popular "shortcut virus"

TIPS: Unhide hidden files (caused by viruses)
This, by chance, came into my mind after a friend of mine lost all his files because his memory card had been infected by nasty viruses (something like trojan or worm or Win32 sality... brrr... which can duplicate the files and hide the real files). So, he asked me how to get those files back. Of course i had successfully retrieved his "missing" files back because i know how to do that. Ngehehehe...

So, here's a simple step which i used to recover the files.I used my own thumb drive as a sample.

1) Of course, scan the flash drive with antivirus first. For most cases, the files/folders are changed into .exe extension files. You can't open the files because... er.. i don't know, it's just that you can't open the file.
* some of the files turned into shortcut...

Chapter 1. Wireless Community Networks

In recent times, the velocity of technology development has exceeded "blur" and is now moving at speeds that defy description. Internet technology in particular has made astounding strides in the last few years. Where only a few short years ago 56Kb modems were all the rage, many tech heads now find themselves complaining about how slow their company's T1 connection seems compared to their 6Mb DSL connection at home.

Recover a Corrupted System File

If an essential Windows file gets whacked by a virus or otherwise corrupted, restore it from the Windows CD. Search the CD for the filename, replacing the last character with an underscore; for example, Notepad.ex_. If it's found, open a command prompt and enter the command EXPAND, followed by the full pathname of the file and of the desired destination: EXPAND D:\SETUP\NOTEPAD.EX_ C:\Windows\NOTEPAD.EXE. If either pathname contains any spaces, surround it with double quotes.

If the file isn't found, search on the unmodified filename. It will probably be inside a CAB file, which Win XP treats as a folder. Simply right-drag and copy the file to the desired location. In other Windows platforms, search for a file matching *.cab that contains the filename. When the search is done, open a command prompt and enter EXTRACT /L followed by the desired location, the full pathname of the CAB file, and the desired filename; for example: EXTRACT /L C:\Windows D:\I386\Driver.cab Notepad.exe. Again, if the destination or CAB file pathname contains spaces, surround it with double quotes.

1. Start, Run, 'Regedit'.
2. Press 'Ctrl'+'F' to open find box and type 'Recycle Bin' to search.

4. Press F3 to continue searching for 'Recycle Bin' and change wherever you come across 'Recycle Bin' to new its new name.
5. Repeat step 4 until you have finished with searching and changed all values to its new name.
