The way for fraud gangs to obtain personal information inadvertently "betrayed" their friends when chatting and interacting.

There is a similar situation: some netizens write logs or post pictures in QQ space, and friends comment or forward them.

However, some QQ numbers are the most common information leakage channels. In various forums and social networks, QQ number is often "required" or "suggested" when filling in personal data.

Usually QQ email directly displays the QQ number, and criminals can get information from QQ.

QQ space and other channels to obtain personal information, such as name, position, company and other personal information. All kinds of online shopping, virtual communities, social network accounts, whether online shopping, registering some forums, communities, websites, or posting information in Weibo, WeChat, QQ space, will leave some personal information more or less.
