CCTV News:Pretending to be an acquaintance to borrow money, pretending to be a public security bureau, a procuratorate or a court officer to investigate a case, and hiding a Trojan link &hellip in short messages and QR codes; … These tricks must have made everyone immune, but do you know? Some telecommunications services that you have never heard of have also begun to become new traps set by scammers!

The mobile phone was locked and more than 50,000 yuan was stolen.

　　When he woke up, Mr. He in Shenzhen found that his mobile phone was locked. At the same time, a shopping platform account was stolen by strangers. Criminals used white bars to spend and apply for loans, and robbed more than 50,000 yuan overnight.

　　Later, Mr. He discovered that his mobile phone had been taken over by a strange number. The short message from the operator shows that this is a business to add a secondary number, and Mr. He’s mobile phone number was added as a secondary number by criminals. When the secondary phone is turned off, all short messages will be received by the primary phone, and criminals will receive Mr. He’s short message verification code during this period, and then commit crimes.

"Subnumber" ≠ "kinship number"

　　Without an ID card, a bank card or even a real name, the money is gone. What the hell is a minor number?

　　Many people think of "family number" at first, but "deputy number" and "family number" are not the same thing.

　　Family number usually refers to the phone bill package opened by different owners and different numbers in order to make calls between them cheaper, and the secondary number is the "one card with many numbers" service provided by operators. On the basis of not changing mobile phones and SIM cards, users can add up to three real mobile phones as secondary numbers. The main and auxiliary numbers can stand by at the same time, and you can freely choose any number to dial, answer the phone and send and receive short messages as needed.

Don’t reply to text messages too casually.

　　Then, how did Mr. He’s mobile phone number become the "secondary number" of criminals?

　　Reduction of criminal modus operandi

　　Step 1: Buy materials.Criminals buy leaked names, bank card numbers, ID numbers and reserved mobile phone numbers online, commonly known as "four big pieces".

　　Step 2: Fishing.Criminals apply to the users who have mastered the bank card information, initiate the business application of binding the sub-number, and find the target of the crime by casting a net widely. Once you reply by mistake, you are hooked.

　　Step 3: Forced shutdown.Because the main number can only take over the SMS when the secondary number is turned off, criminals usually use two means at this time. One is to use SMS bombing to force the target to turn off the mobile phone, and the other is to use the mobile phone cloud service to remotely operate the mobile phone.

　　Step 4: White Wolf with Empty Gloves.Using the SMS verification code received by the main number, criminals ransacked the online shopping account bound to the mobile phone number.

　　Patterns are stacked, and it is impossible to prevent them! For this kind of fraud, after receiving all kinds of SMS notifications, you must read the content of the SMS clearly and do not reply at will.

"SMS custody" business is also not very secure.

　　After the SMS storage service is opened, you can save your mobile phone messages on the server of the operator. Now, many mobile phone manufacturers’ cloud services are doing the same thing. However, this is a hidden danger function.

　　Case review

　　One morning, Miss Ding saw two short messages from banks and mobile phone operators on her mobile phone, which were sent at 3:43 am and 4:12 am respectively. As soon as the account is checked, the balance of more than 100,000 yuan will be zero overnight! Not only that, Miss Ding also suffered a credit card theft and was "applied" for a bank universal loan of 70,000 yuan.

　　How on earth did all this happen?

　　Reduction of criminal modus operandi

　　Step 1: Hit the database to get all kinds of account information.The so-called "library collision" means using software to try a high probability digital sequence. Using this simple and rude method, the user’s network identity, online banking account number, mobile phone business hall and other accounts can be seen at a glance. Insiders said: "The speed of library collision is very fast, at least thousands per minute. If some good equipment is used, the efficiency is higher and the success rate is above 50%."

　　Step 2: Open SMS storage and SMS interception services to obtain verification code.This is the most critical step. After the opening of this service, the dynamic verification code to ensure the safety of landing has successfully become the bag of criminals.

　　Step 3: Open the physical SIM card.At this point, criminals can pretend to be victims and apply for 4G card replacement service in the online business hall. For the convenience of the people, some operators can express the card directly to the designated address.

　　By intercepting short messages and copying SIM cards, fraudsters can "do whatever they want".

　　As we all know, many important services rely on mobile phone authentication. If you back up the SMS to the server synchronously, it will increase the exposure opportunity. Once the service password of the online business hall is stolen, or the login permission of the cloud service is stolen, it is equivalent to "swimming naked".

The loopholes in the unpopular business are targeted by scammers.

　　The "Research Report on the Trend of Online Fraud in 2016" released by the anti-fraud reporting platform "Hunting Network Platform" proposes that since 2016, online fraud has mainly shown several obvious characteristics:

　　Mobile phone cards have become new theft targets;

　　Jump to the phishing website by using short URL and weiyun sharing link;

　　Well-known recruitment websites and voice platforms for open recruitment;

　　A phishing website that is difficult to distinguish between true and false;

　　The implementation of precision fraud;

　　Fraud professionalism is getting higher and higher;

　　Using loopholes in new business and unpopular business to commit fraud;

　　Use cloud disk and synchronization software to steal information.

　　Among them, the loopholes in mobile phone cards and unpopular business are mentioned.

　　Security experts suggest that we should develop good online habits, don’t click unfamiliar links, don’t fill in our personal information in the website interface with unknown security, and regularly modify the password of social accounts to avoid information such as mobile phone contact information being leaked; Improve safety awareness, develop good habits of using mobile phones, and avoid being infected by mobile phone viruses.

　　Beijing gale cooling: it is estimated that the minimum temperature of level 7 gust is 12℃

　　This morning, there was a strong wind in Beijing, which made me feel cold.

　　China Weather Network reported that due to the influence of cold air, the northern wind began to take over the sky of Beijing at 4 or 5 o’clock this morning. According to meteorological monitoring, as of 5: 30 this morning, gusts of magnitude 6 or above have appeared in Haidian Station, Chedaogou, Xiangshan, Bei ‘an River, Fenghuangling, yongfeng middle school and Minzhuang.

　　Cold air goes south in a big way, and autumn tigers turn into paper tigers in seconds.

　　In addition to Beijing, this morning, most parts of Inner Mongolia also experienced significant cooling, with the cooling rate in some areas exceeding 10℃ and the temperature falling below 5℃.

　　According to the news released by the Central Meteorological Observatory this morning, it is estimated that the temperature in most parts of central and eastern China will drop by 4 ~ 6℃ from north to south from September 27th to 29th due to the influence of cold air, with the temperature drop in the south-south area of eastern Inner Mongolia and the south-central part of northeast China reaching 8 ~ 10℃.

　　Will you cry this winter?

　　For this windy and cool weather, some netizens said, "An autumn rain and a cold, in fact, it is nothing to cool down now. This winter, we may be frozen into dogs."

　　The reason why netizens have the above concerns is because of a word recently swiped — — La Nina.

　　The word "LaNina" comes from Spanish, originally meaning "little girl", which refers to the phenomenon that the sea surface temperature in the equatorial, Middle East and Pacific Ocean continues to be abnormally cold. If the 3-month moving average of SST anomaly is lower than -0.5℃ and lasts for at least 5 months, it is judged as a La Nina event.

　　Monitoring shows that in August 2016, the SST anomaly index in the equatorial Middle East Pacific was -0.53℃. According to the National Climate Center of China Meteorological Bureau, the equatorial Middle East Pacific entered La Nina state in August.

　　Li Xiaoquan, chief meteorologist of China Weather Network, said in an interview with Zhongxin. com (WeChat WeChat official account: cns2012) that it is still early in winter, and the authoritative meteorological department has not given the final forecast figures. It is still inconclusive whether La Nina will occur this winter.

　　"But now that we have entered the La Ni? a state, La Ni? a events may occur this winter. According to relevant analysis, in general, the probability of being cold this winter is greater." Li Xiaoquan said.

　　How powerful is La Nina?

　　According to China Weather Network, one of the impacts of La Nina event on China’s climate is that the temperature may be low in winter, which is prone to cold winter. Statistics show that since 1954, in the years affected by La Ni? a event, the proportion of cold winter in China has exceeded 80%.

　　For example, in the years affected by La Nina, the winter of 1954 was the coldest one, and the temperature was 2.95℃ lower than normal.

　　For another example, in early 2008, the La Nina incident was one of the important behind-the-scenes "pushers" of the once-in-50-year freezing rain and snow disaster in southern China.

　　According to regional statistics, in La Nina, the proportion of cold in winter in Tibet was the lowest, at 50%. In the northwest, southwest, south China and south China, it is as high as 80% or more.

　　Will La Nina definitely lead to a cold winter?

　　Will La Nina definitely lead to a cold winter? Li Xiaoquan said that normally, when La Nina happens, China will be colder in winter, but it doesn’t mean that it will enter the cold winter, but the probability of entering the cold winter is higher, especially in the southern region.

　　"La Nina came last year, which will make winter cold, but it doesn’t mean it will be particularly cold. It can be seen that some years have entered the cold winter, which is mostly related to the La Nina phenomenon, but it is not La Nina that will definitely enter the cold winter. "

　　As it said, it was also the winter of 1998/99 when the super El Ni? o turned to La Ni? a, but China experienced a warm winter.

　　China Weather Network reported on September 22nd that the equatorial Middle East and Pacific Ocean has entered La Nina state, but it has not reached the standard of La Nina event. China Meteorological Bureau will continuously monitor the development of La Nina.
