What should I do if my mobile phone sends a lot of verification codes?

1. The mobile phone receives a large number of verification codes.

Received a lot of verification code information, and security experts put forward some practical security suggestions:

1. Strengthen business process audit to ensure that all mobile phone value-added services must be confirmed twice by the user's mobile phone.

2. When synchronizing the user's SMS information to the website, you should deliberately set a certain delay, so that even if the attacker reads the user's verification code from the SMS safe deposit box, these verification codes have actually expired.

3. When synchronizing users' short message information to the website, sensitive information such as verification code should be automatically filtered or encrypted to prevent relevant information from being used by criminals.

Mobile phone users can try some simple and effective methods to avoid or reduce the losses caused by such crimes as much as possible:

1. Modify your online banking password regularly, and set a strong and complex password. Try not to use the same account and password on all websites, especially social accounts, online banking accounts and common mailboxes. You must set a separate password.

2. Once you receive a short message similar to "Subscribe to SMS security service", immediately contact the relevant operators for disposal and close the relevant services in time. If you receive a short message from the bank shortly after receiving the short message from the short message safe, you should immediately contact the bank customer service to report the loss of the relevant bank card, so as not to cause more losses.

3. If you suddenly receive a large number of inexplicable spam messages or verification code messages, you must carefully check whether there are verification messages or transfer consumption notification messages sent by banks or third-party payment tools. If yes, contact the bank to report the loss of the bank card or contact the third-party payment platform to freeze the payment account. And use 360 mobile guards to kill Trojans, intercept phishing websites, and isolate and protect transaction verification code messages through paid bodyguards.

2. Why do mobile phones receive many verification messages for no reason?

Mobile phones don't receive verification code messages from websites for no reason. Generally, your mobile phone number is leaked, used by criminals, bombarded by short messages, and spam messages such as verification code are sent to your mobile phone number in a short time; The following is a detailed introduction:

1. Generally speaking, the verification number is only valid if it is sent to the corresponding mobile phone for login. If you receive a lot of verification numbers inexplicably, your mobile phone number may be leaked for some reason;

2. Or for some reason, your mobile phone number is bombarded by criminals using short messages, and constantly sends spam such as verification code to your mobile phone number; You can try to use third-party mobile phone housekeeper and other software to set up harassment interception to minimize harassing text messages.

3. I don't know what happened to my mobile phone, but I suddenly sent a lot of verification code messages, not * * *, but also.

The mobile phone number is bound by someone else, or someone tries to crack your account password.

Verification code SMS is free, usually because of registration. Maybe someone wants to register an account, but mistakenly entered it as your mobile phone number. If the mobile phone receives the malicious fraud verification code, intercept it with the mobile phone housekeeper.

If you don't give up texting for a long time, someone may use the verification code vulnerability to maliciously harass. But it does not rule out server errors, pseudo base station fraud and so on.

Verification code can prevent malicious password cracking, ticket brushing and forum flooding, and effectively prevent hackers from constantly trying to log in to specific registered users by using specific program brute force cracking methods.

You can blacklist the source number or complain to the source website. Do not rule out malware, you can report it. If you don't do it yourself, you can block these messages and pay attention to your mobile phone binding and account password security.

4. What should I do if I receive many verification codes?

Received a lot of SMS verification codes, generally there are several situations:

1 Mobile phone has built-in charging software. When it is connected to the Internet, it will automatically send a verification message. In this case, you should pay attention. It is best to get a license to uninstall the paid software.

2. When users use some software, they inadvertently click on the purchased or customized information and the confirmation information sent by the game player. This requires users to check or call the customer service phone of the number operator to find out what the SMS number is.

3 mobile phone poisoning phenomenon, poisoning will also have spam messages, but generally it will not be verification code messages, you can try to solve it through antivirus.

If it is not for the above reasons, you can use the SMS interception function of a third party to block the SMS. For example, 360 mobile guards and so on.

First, the reason for the failure:

2. Or for some reason, the mobile phone number is bombarded by criminals using short messages and constantly sends spam such as verification code to the mobile phone number; You can try to use third-party mobile phone housekeeper and other software to set up harassment interception to minimize harassing text messages;

Second, the solution:

1, you can install the mobile phone housekeeper to set interception and blocking, and the mobile phone housekeeper can set harassment interception to prevent sending short messages again; You can also set words appearing in spam messages as keywords; You can also report intercepted spam messages and harassing numbers, which can improve the accuracy of mobile phone housekeepers.

2. Strengthen business process audit to ensure that all mobile phone value-added services must be confirmed by the user's mobile phone twice.

3. When synchronizing the user's SMS information to the website, you should deliberately set a certain delay, so that even if the attacker reads the user's verification code from the SMS safe deposit box, these verification codes have actually expired.

Common troubleshooting of mobile phones:

Fault symptom: the mobile phone can't receive SMS.

1, something went wrong for no reason.

Suddenly I couldn't receive the text message, and there was nothing wrong with my mobile phone, so this problem appeared. This situation is usually not caused by a broken mobile phone, but by a small problem on the operator's server and network delay. , so I dial the mobile phone network to operate the mobile 10086, telecom 1000, China Unicom 10 108 and other service stations.

2, mobile phone arrears

This is the most basic question. Nowadays, mobile phones generally evaluate the credit rating. If the credit rating is high, the amount in arrears will be greater, depending on whether the payment is timely linked to the credit rating. If you are in arrears, you will not directly cut off the phone and SMS functions. So, when you can't receive the SMS, think about whether the operator sent a SMS to urge you to pay the phone bill, and didn't pay it.

3. The storage of the mobile phone is full.

This situation is generally common in non-smart phones, thinking that the storage space of non-smart phones is generally limited, and many text messages are saved by default as mobile phone cards, and the storage capacity of mobile phone cards is very small, so they are generally easy to fill up. At this time, you need to delete some short messages or other things that occupy memory.

4, SMS center number settings

I can't get the text message. Maybe there is something wrong with the number setting in the SMS center. For this problem, you can set the number of SMS center correctly in the mobile phone information settings, and then confirm it to solve the problem.
