What are the characteristics of SMS fraud?

SMS fraud is characterized by strict division of labor, huge quantity, wide distribution, local binding, great temptation and low cost.

1, strict division of labor

Most criminals who send illegal text messages by mobile phones are gangs, and the division of labor within gangs is strict. Some buy mobile phones and mobile phone numbers, some open bank accounts, some send mobile phone short messages in groups, some are specially responsible for sending short messages, and some withdraw money from ATM machines. After success, they immediately hide, which is very concealed. "I can't see people, I only hear voices."

2, the number is huge

The number of illegal short messages sent by mobile phones is huge. More and more criminals can send illegal information to a large number of users in a short time by using special tools such as SMS group sender and group software. Fast and wide, send thousands of articles at a time, and someone always falls for it. Therefore, it is fast, destructive and harmful.

3. Widely distributed

The activities of sending illegal mobile phone short messages mostly use mobile phone numbers in different places. Sending short messages, opening bank accounts and withdrawing money are usually not carried out in one place, but in many places, and the geographical distribution is quite extensive. It has cross-regional liquidity.

4. Local binding

Some mobile phones in different places are tied to local number one, which is easy to be mistaken for indoor fixed telephones. Because the receiver regards it as a local phone, the vigilance is relaxed, the foreign people have a sense of distance, and the local people have a sense of trust, which provides an opportunity for criminals and is difficult to identify.

5. Very attractive

The content of illegal short messages on mobile phones is more and more attractive and irresistible. What's more, impersonating banks and public security organs, impersonating financial departments, and taking advantage of people's trust in banks and public security organs to cheat are very deceptive.

6. Low cost

SMS is mainly via SIM card, and the technical content of letter fraud is not high. With a group sender, several short message cards, mobile phone number segments and a computer (sometimes without a computer), you can send a large number of fraudulent short messages in groups.

The most important thing is the short message card, which is no different from the mobile phone SIM card sold in the market. The price of SMS familiar to users is 0. 1 yuan or 0. 15 yuan, and the monthly card is cheaper. When texting, the card number of the card will be displayed on the mobile phone, but it can only be used for texting, not talking. All short messages are transmitted through the operator's platform and pay a certain fee.
