Dump Wechat Messages from Android

How to use:

Install Dependencies:

• numpy
• PIL
• audioread
• sox

Get Necessary Data:

• Get /data/data/com.tencent.mm/MicroMsg/long-long-name/EnMicroMsg.db from rooted phone:
• Get Wechat resource directory, usually at storage:/tencent/MicroMsg/long-long-name
• Get Wechat uin:
  • login to web-based wechat; get wxuin=1234567 from document.cookie
  • Or get default_uin from /data/data/com.tencent.mm/shared_prefs/system_config_prefs.xml.
• Get phone IMEI:
  • Call *#06# on your phone
  • Or find IMEI in system settings
  • Or use adb shell dumpsys iphonesubinfo | grep 'Device ID' | grep -o '[0-9]*'

Run:

• Decrypt database and get decrypted_db.db (for now, Linux x64 only):

./decrypt_db.sh <path to EnMicroMsg.db> <imei> <uin>

• Parse and dump text messages of every contact:

./dump_msg.py decrypted_db.db output_dir

• Dump messages of one contact to html (for now, raw message only):

./dump_html.py decrypted_db.db <resource directory> <contact name> output.html

TODO

• parse audio messages, links, emoji and images
• output to rich-content html
