how to hack anyone whats app

1. WhatsApp Sniffer 

WhatsAppSniffer is a tool for root terminals to read WhatsApp conversations of a WIFI network (Open, WEP, WPA/WPA2). It captures the conversations, pictures / videos and coordinates that aresent or received by an Android phone, iPhone or Nokia on the same WIFI network. It has not been tested with W indows Phone terminals. It can't read the messages written or received by the BlackBerry's, as they use their own servers and not WhatsApp's.
This application is designed to demonstrate that the security of WhatsApp's communications is null. WhatsAppSniffer just use the TCPDump program which reads all the WIFI network packets and filters those which has origin or destination WhatsApp's servers. All messages are in plain text, so it does not decrypt anything, complying fully with the legal terms of WhatsApp (3.C: "While we do not disallow the use of sniffers Such as Ethereal, tcpdump or HttpWatch in general, Any we do going efforts to disallow reverse-engineer our system, our protocols, or explore outside the boundaries of the ordinary requests made by clients WhatsApp .... ") 

For WPA/WPA2 encrypted networks, if uses the tool ARPSpoof (optional).

2. Decrypting Conversations

have your victim locked his whatsapp? or you want all his conversation on your PC. Generally for security reasons WhatsApp encrypt Conversation while taking backup in SD Card or Phone Memory.But i have found a tool on XDA that claims to decrypt all the whatsapp conversation down to your PC.

If you have some access over his device you can also send files from Bluetooth to your device and later read all the conversations.

This tool is called WhatsApp Xtract and for this all credits goes to ztedd

Some general advice on how to backup Whatsapp and get the database file:

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!
