Complaint:
Answer 7 sales calls in the morning.
Who leaked my personal information?
Wang Xiaoqiang (pseudonym) is from Qiandao Lake, Zhejiang. He is a small boss on the construction site and went back to his hometown to work a few years ago.
On June 65438+1October 10, he went to Hangzhou to see the children from his hometown construction site. Around noon 1, the three of them visited the Leifeng Tower and went to eat near Wu Shan Square. So in the morning, he received seven phone calls, most of which were sales calls. Wang Xiaoqiang said that one of the numbers selling silver wealth management hit him three times in a row, which made him very disgusted. "When the third call came back, I hung up. My wife began to have opinions and explained it for a long time before dispelling doubts. "
When he came home in the afternoon, Mr. Wang was depressed. In the last two months, he has always received calls from gold shops, silver investment and senior manager training. Several times, he almost had an accident in order to answer these calls. He always had a question in his heart: How did these people know my mobile phone number?
He called back in the opposite direction, either "this number doesn't exist" or the other party just said "I know your number. What do you care?" He concluded that these mobile phones have several characteristics:
First, these calls basically start with the foreign area code or 400, and they have been frequently dialed in the last half month;
Second, the other party knows that he is the boss, but he does not know the specific occupation;
Third, the other party knows his home address in Hangzhou, but he doesn't know whether he is tall or thin.
Fourth, the other party knows that he has a BMW, but he doesn't know the license plate number.
Of course, there is another feature. The caller knows his personal information very well, but he doesn't know any of them.
"How do these people know my name and family situation? I have received sales calls before, but there is not so much information. " Wang Xiaoqiang suddenly remembered one thing: 1 month ago, he set up a supreme card in a bank in Hangzhou. "Is it because the bank leaked my personal information?" When he complained to the media, he said that if his guess came true, how many people would answer sales calls as frequently as he did every day.
Unannounced visit:
700,000 pieces of bank card information only sold for 6.5438+0.3 million yuan.
The main buyers are the sales staff of financial institutions.
It is not a new problem where the card opening information of bank cards comes from. The staff of an investment management company in Hangzhou hit the nail on the head: go online and have a look, the price is cheap and you can buy it everywhere.
According to the clues of the above-mentioned people, the reporter used the QQ group search function to search for the keyword "telemarketing" and found about 144 QQ groups with "data exchange" function. Search "bank card information", there are at least 120 groups, with more than 30 participants, and the transaction is active. Further narrow the search scope "Hangzhou bank card information" and find the 12 QQ group. It is some QQ groups above that constitute the "black market" of credit card information transaction.
The reporter randomly joined a QQ exchange group of "telemarketing data source" and soon contacted a seller named "All kinds of bank data (fidelity)" as a buyer.
The seller claims that he owns tens of millions of data of banks across the country, including more than 5 million bank card account opening information in Zhejiang and more than 700,000 in Hangzhou. The "lowest price" he can give is: the bank card information in Zhejiang is 50,000 yuan, and that in Hangzhou is 654.38+0.3 million yuan. He said that the main buyers of this information are telemarketers of financial institutions such as precious metals and trusts. Only in his group, dozens of people consult the price every day. Old information is cheap, but new information is expensive. On average, the price of each piece of data will not be less than 0.03 yuan.
Another information seller has a similar reaction. The other party said that the information of the old card is generally 0.03 yuan/card, and the information of the newly opened card in Hangzhou (after 2065438+June 2004) is more expensive, with an average of 0.5 yuan/card. VIP customer information of some banks, such as gold and platinum cards, requires more than one 2 yuan. He sent seven pieces of bank card information to reporters for free, including the cardholder's name, gender, mobile phone number, ID number, home address and bank.
Verified three pieces of local information in Hangzhou. In addition to a mobile phone number, the other two owners verified the *** 12 information reported by the reporter, and the accurate information was 9.
