How do scammers who impersonate others cheat?

On weekdays, after we changed our mobile phone number, we used to tell our relatives and friends to change the address book information by sending short messages in groups to facilitate future contact.

Recently, the Anti-Telecom Fraud Center of Guangzhou Public Security Bureau found that this seemingly ordinary action was targeted by fraudsters. Citizens will fall into a scam if they are not careful!

Recently, some citizens reported that they had encountered this new type of "number-changing deception": they were impersonated by swindlers, claiming to have changed their numbers and cheated the relatives and friends of counterfeiters. Liar number starts with 132.

Liar: (texting) "This is XXX. I will use this new number from now on. The original number has been discontinued. Please keep it. Please reply when you receive it. Thank you. "

Victim: (calls back the new number) And you are? ...

Liar: I remember. This is my new number. Please write it down (and then hang up).

The next day, the liar called again.

Liar: I was caught calling a lady in Guangzhou last night. Can you send me some money and do me a favor?

Victim: Who are you?

Liar: I'm Xiao Wu. Didn't you save my number yesterday?

Victim: Which Xiao Wu, Wu What?

The liar knew that he couldn't cheat any more and hung up immediately.

Impersonating an acquaintance is now an upgraded version.

In fact, similar "number change scam" has appeared before, which comes from "guess who I am", pretending to be an acquaintance of the victim for fraud, but the pattern is constantly being refurbished.

For example, pretend to be the landlord and send a text message: I am the landlord. Please write it down when changing the number and call me later. In addition, the rent will be charged to my wife's card, the card number of Agricultural Bank ... Thank you!

Others pretend to be acquaintances, claiming that they changed their numbers and called directly, such as the typical "guess who I am" fraud.

The new upgraded version pretends to be an acquaintance. After illegally obtaining the victim's address book information, it calls him by his first name, sends a text message claiming to change his number and does not call. After you update your address book, it is even more deceptive to impersonate your relatives and friends by SMS. I will call for verification when I encounter something, and I often refuse to answer the phone for various reasons.

For example, after receiving the short message of "borrowing money to transfer money", the victim thought that his relatives and friends were in trouble, and when he was ready to dial the "new number" to confirm, the other party refused to answer. "I didn't answer the phone, played three times. I felt even more strange, so I called the original number of XX and got through! Xxx answered the phone! He didn't change the number at all! This man is a liar! "

Real case

"I am XXX, and I will use this new number from now on. The original number has stopped. Please keep it. Please reply when you receive it. Thank you. " This is a short message that Ms. Zhang received the other day.

Because the other party can accurately report the name of the boss, Ms. Zhang updated the "new number" of the "boss" to the address book without his meaning. Two days later, the "boss" sent a text message asking Ms. Zhang to help transfer the money, and proposed to transfer the money to Ms. Zhang's bank account first.

After Ms. Zhang provided the account number, the other party also sent a screenshot of online banking to prove that the money had been remitted. When Ms. Zhang saw the screenshot, she believed it and transferred 20,000 yuan to the designated account of the other party. It was not until she saw the boss that she was cheated.

The police of the Anti-telecom Fraud Center of Guangzhou Public Security Bureau said that after we received the text messages claiming that friends and relatives changed their mobile phone numbers, they would generally be saved without further verification. It is this inertia that fraudsters use to find opportunities to start. Criminals will first obtain citizens' address book information through various means. When sending information, scammers can further reduce the victim's defense by swearing.

Secret:

Steal the list of friends through various channels.

Many people wonder: how did the liar get the phone numbers of relatives and friends? There are too many ways to steal. It's too easy. Li Tiejun, a cheetah mobile security expert, said that it is still easy to steal the address book. On the one hand, a large number of netizens have no resistance to fraud, personal information is distributed casually, accounts are misused casually, and users simply don't know after information is stolen.

On the other hand, the scammer sends a virus and installs it on the user's mobile phone, and the contact information of seven aunts and eight aunts in the user's mobile phone address book is available. The police said that, for example, the criminal suspect sent short messages and QQ messages containing malicious Trojans to others, such as "children's report cards, photos of class reunion, private photos, wedding invitations" and other content messages to defraud the other party to click on the Trojan link. Once clicked, the Trojan virus will automatically run in the background of the mobile phone. After running, it will read the phone address book, send a scam message "I changed my number" to friends in the address book, and then borrow money from friends and relatives in your name. At the same time, some scammers will send this short message to all your friends in your name to induce more people to fall for it.
