Android :-

- In Whatsapp go to settings - more - Backup Chats
- Copy the folder "Whatsapp" on the SD card to your backup location (e.g., PC)
- (ideally also) use the app Titanium Backup to backup the full whatsapp application together with its data, copy the backup from the folder "TitaniumBackup" on the SD card to your backup location (e.g., PC)
- Use this tool Whatsapp Backup Extractor (download in this thread) to show the chats in a friendly readable format. The necessary files "wa.db" and "msgstore.db" you will find inside the Titanium Backup archive "com.whatsapp-[Date]-[some digits].tar.gz", alternatively (without Titanium Backup) you can use the msgstore.db.crypt file from the folder Whatsapp/Databases on the SD card.

iPhone :-

- use Itunes to create an unencrypted Backup
- use an Iphone Backup Tool to get the file net.whatsapp.WhatsApp/Documents/ChatStorage.sqlite, e.g. I-Twin or Iphone Backup Extractor. Make sure to create an unencrypted backup with Itunes, as these tools can't handle encrypted backups. Another possibility are forensic tools like UFED Physical Analyzer.)

Blackberry :- 

- sync your blackberry with desktop manager and then copy the messagestore.db file from SD
- however, it seems that this file is encrypted? Currently we don't know how to get the unencrypted messagestore.db file
- Blackberry not supported yet!
 

Nokia- not known yet
- Nokia not supported yet!!! 

So before giving your phone to anyone think twicely and also keep all your backup safe so that no one can hack your personal stuff and messages. :-) 

==================================================================

3. Using Spywares :-

Another method we are going to see is that by using 3rd party application and software anyone can easily not only hack your whatsapp but it can track GPS, view your lock screen password, view your messages, call records etc.

There are many software available in the market to do such thinks but the truth is that they all are paid app but i have come across a 3rd party software which is absolutely free of cost and that is call BOSSPY. It is available only for android and Iphone till now.

I have use it in my S3 and it works like a charm to see whether its really working or not and i was shocked to see that it can actually track all my call records, in/out text messages, it can track me via GPS and the great and very dangerous think about this app is that it is totally invisible means you cannot find this app in app drawer but it can be found under setting => accessibility => Service tab. There you will find this app. To start this app we need to dial the default code which is 123456 in android dialer. For further detail visit the official page of BOSSPY.

 

==================================================================

So guys that all for today.

In next post i will be sharing some other dangerous method through which anyone can hack your whatsapp

Till then stay tune to my blog.

if i have help you in any way please do comment and share it as much as you want to protect your dear one from being hacked by someone.
