[WeChat] When collecting evidence, clearly distinguish WeChat nickname, WeChat ID, WeChat account, and WeChat ID at one time
The difference between " visible and invisible " - [suy]
Article directory
(1) WeChat account (ID) - "Permanent uniqueness"
The WeChat account is the original WeChat account ID automatically generated by the system , starting with " wxid_ ", and the initial default WeChat account = WeChat ID.
After each WeChat successfully registers and logs in for the first time, the system will automatically assign a default WeChat ID number (starting with "wxid_"). There is an opportunity to modify it, but no matter how the WeChat ID is modified, the WeChat ID number under the WeChat system folder The ID number will " always " be the original WeChat account (ID) and will not change when the "WeChat ID" changes .
(2) WeChat ID - "Short-term Uniqueness"
WeChat ID is a number that distinguishes different WeChat IDs. It cannot be repeated with other people’s WeChat IDs. Currently, it can be modified once a year. During the period of use of WeChat ID, it is the only certificate that distinguishes different WeChat IDs . It has a special " uniqueness within the validity period " ", mostly used for " searching " WeChat ID.
1. WeChat ID setting rules
WeChat ID must start with a letter or underscore, and can use 6-20 digits, letters, underscores, minus signs, or a combination thereof.
2. WeChat name can be changed
Android WeChat version (v7.0.15) and later has launched a new function that can modify WeChat ID.
3. Modify WeChat ID conditions
Modification needs to meet two conditions: no WeChat ID has been modified in the past year and the current account has no security risks; after the modification is successful, others can only search for you through your new WeChat ID, and can no longer search for you through the old WeChat ID .
4. Modify WeChat signal path
Modify the WeChat ID path: Click WeChat->Me->Settings->Account and Security->WeChat ID->Modify WeChat ID; or: Me->Personal Information->WeChat ID->Modify WeChat ID.
(3) WeChat nickname - "Not the only one"
There is no limit on the number of modifications. You can change it at any time, or you can have the same name as another person’s WeChat nickname. It is just for the convenience of yourself or others to remember. It is equivalent to an individual's "name", and there may be "duplicate names".
Summarize
WeChat ID can be modified, but WeChat account cannot be modified .
WeChat account (WeChat ID): When a user uses a mobile phone number to register a WeChat account, the system automatically matches the generated " original account ID " (starting with " wxid_ ", which is permanently unique ), which is also the initial WeChat ID ; only WeChat The account number cannot be changed, but the WeChat ID can be changed again .
WeChat ID: The account used when logging in to WeChat is the " unique identification number " in the system. WeChat ID can be modified once a year, provided that the corresponding conditions are met.
Many forensic vendors often mix WeChat account, WeChat ID, and WeChat ID together, which looks extremely confusing (or the changed " WeChat ID = WeChat original account (ID) ", so that in terms of evidence retention and display, problems are likely to arise); due to limited personal abilities, I only write some understandings from my own perspective. Please correct me if I am wrong!
