Mobile phones, bank cards and I "nest" at home. When I wake up, the balance in the card has been stolen and used up. At present, such cases of stealing bank cards using "sniffing" technology have occurred in many places. The reporter learned from the Chuzhou Public Security Bureau of Anhui Province that this new type of cyber crime has been upgraded to the 4G network field. The police remind that when the mobile phone signal drops from 4G to 2G and unknown SMS verification code is received, the risk of stealing and swiping should be prevented.

According to the police, this kind of stealing and swiping cases often use "sniffing" devices to intercept mobile phone short messages within the signal range of the base station. At the same time, criminals use technical loopholes in banks, websites and mobile payment software to obtain the name, ID card number, bank card number and other information of the mobile phone owner. In this way, the short message of the victim's mobile phone verification code can be intercepted in real time, and the game coupons can be resold after being recharged with mobile phone charges, or the money in the victim's bank account can be directly swiped through quick payment.

In this regard, the police warned that when encountering a similar "attack" of stealing and swiping, the mobile phone signal would suddenly drop from 4G to 2G, and an unknown SMS verification code might be received. At this time, you need to immediately shut down or turn on "flight mode", immediately contact the mobile application and website service provider to which the SMS belongs, find out the source of the SMS verification code, and check your bank account Whether the mobile phone charges and payment applications are stolen. Once the funds are stolen, the bank card should be frozen as soon as possible, the SMS content should be retained, and the alarm should be sent immediately.

At the same time, the police remind everyone to protect sensitive private information such as mobile phone number, bank card number, ID card number and payment platform account. Illegal people often choose to commit crimes at night and turn off the secret free payment function of mobile phones before going to bed, which is conducive to ensuring the security of funds.
