Whatsapp Business not Supported (Alternate Solution Available)

[yapkahfung123]

--EDIT--
The WhatsApp Business is not vulnerable to the downgrade attack, which rendered this extractor useless against it.
For other solution, see #1 (comment).

I guess that directory is not for storing the databases? Could you show me the file list inside the directory?

This error is due to the system cannot find the Java executable, hence, no tar file is generated.

However, as I investigate WhatsApp Business further, I found that adb backup may not work in WhatsApp Business. Although android:allowBackup is set to "true", the android:backupAgent is set to "com.whatsapp.registration.backuptoken.BackupTokenAgentHelper". We may need to implement a "BackupAgent" class that has the same class name as above in order to deal with the backup.

So, rooting may be the best luck for now. I will look into it deeper.

Sure. It has 3 folder inside

If you are not able to root your device, you may install WhatsApp Business in an Android x86 or emulator with root privileges. Install and restore the backup of your WhatsApp Business. By then, you can extract the data by:

adb pull /data/data/com.whatsapp.w4b

You mean that i have to root my device in order to extrace the databases ?

[KnugiHK]

Sure. It has 3 folder inside

Yeah, they are just the crypt14 backup, which can be copy to the computer manually without trouble. However, you will need the key to decrypt those crypt14 files, which is only available in /data/data/com.whatsapp.w4b

It is optional to extract databases with root as you have crypt14 files in your external storage. But it seems to be essential to extract the encryption key with root. So,

Option 1:
Extract the plaintext database with root.

Option 2:
Extract the encryption key file with root and decrypt the crypt14 files with Whatsapp-Chat-Exporter.

data/com.whatsapp.w4b

I looking thru /Andriod/data/com.whatsapp.w4b. There is no key to for decyption.

[KnugiHK]

/data/data/com.whatsapp.w4b is different from /Andriod/data/com.whatsapp.w4b.

The full path of /data/data/com.whatsapp.w4b in Android system is /data/data/com.whatsapp.w4b
The full path of /Andriod/data/com.whatsapp.w4b in Android system could be (depends on device) /sdcard/Andriod/data/com.whatsapp.w4b

/data/data/com.whatsapp.w4b can only be accessed with root if adb backup is not working.

[yapkahfung123]

I can't see any data folder in my internal storage. Looks like want to root the device

[KnugiHK]

Yup, you may need to root the device.

Hi KnugiHK, may i know if the whatsapp business is currently installed on an non-rooted android. Can I move the key to a rooted device? My sim card has lost, so I cannot login my whatsapp business account anymore....

Do you mean can you move files in WhatsApp's internal storage to a rooted device from a non-rooted Android?

yesyes. My sim card for my whatsapp business is loss. So I have loss my whatsapp business account. The sim card user has validated the whatsapp number and my whatsapp business account is logged out already.

But I just want to get back my whatsapp business history. But my phone is not rooted Samsung device. I checked online, seems root it now will need a factory reset of my device and deleted my whatsapp business file in my non-rooted android. But as my file is unrooted now, seems i cant extract my key file....
