Xiao Song first asked his friend about his illness. The other party can't accurately tell the illness, and can't tell the exact cost of the need, just emphasizing the urgent need. For the money transferred to Xiao Song in advance, he once again stressed that it would be delayed, hoping that Xiao Song could transfer the money to the emergency first. At this point, Xiao Song realized that he might have encountered online fraud, which is very similar to the situation of "pretending to be an acquaintance to borrow money for fraud" in the school's anti-fraud propaganda. Later, Xiao Song pretended to cooperate. First, he said that he didn't have 5000 yuan in his card, so he could ask his parents for money to remit money to the bank. He needs the other party to provide his account number and account name, and then transfer the money after he gets the money. In a short time, I sent a bank account number and account name of a so-called "hospital" to Xiao Song. Xiao Song, who got the relevant account information, immediately opened the National Anti-Fraud Center App, clicked "I want to report a case" and gave his own experience back to the police. Finally, Xiao Song got in touch with his friend and learned that his friend's QQ account was stolen, which further confirmed that this was a fraud.
