Private domain defense in the cotton Era

“ Won't! ！ I met a hacker ？” Xia ideal never dreamed of , I made it myself 12 Annual retail , One day, I have to deal with internet black industry . At this time, the office is still immersed in a lively Carnival , Only three people stared at the number flashing in the background of the applet , Frown tight , Lost in thought .

These three men are from the cotton era “ Three swordsmen ”： Li Huacheng 、 Xia ideal 、 Su Zhibin , Responsible for smart retail strategy .

Black production in the Jianghu

Where there are people, there are rivers and lakes , Where there are interests, there are black products . 2020 year 8 month 18 Japan 00 when 00 branch , The annual super member day of the cotton era officially kicked off . They are ready to 10 Ten thousand free gift packs are returned to fans in the app mall , Hope to add a fire to this annual ceremony . Tick by tick . 5 Minutes less than ,10 Ten thousand gift bags were snatched away . “ It's too fast ！” The team cheered and celebrated with emotion .“ Know that this activity may be hot , I didn't expect it to be so popular .” As the head of the official e-commerce new retail , Xia ideal is as excited as the team . This result , It is undoubtedly the best affirmation of their efforts in the past month .

Soon , Xia idealized that something was wrong , The unusual speed of collecting made him beat the drum in his heart .

He remembered seeing a set of data not long ago —— The current e-commerce applet in the industry ,DAU About ten to twohundredthousand . And the small program in the cotton era , The event was launched in less than five minutes , More than 200000 users poured in .

“ We should not encounter the network black production ？” He asked tentatively .

Take root in the retail industry 12 year , Xia idealism only saw illegal hackers and network hackers in the news . In my impression, these are different from my daily life , Not to mention their own small programs will be targeted .

To test your ideas , Xia ideal finds suzhibin and lihuacheng .

“ Different from online users across the screen , I don't know whether the other party is a human or a robot , Users of offline stores can see and touch .” Lihuacheng is the person in charge of the store , Compare the database , They did find something fishy .

Xia ideal, who is in a difficult mood, has done one more thing “ Stupid thing ”. He then drew hundreds of mobile phone numbers , Call with the customer service team . The result is that it either doesn't work , Or no one answers . Many signs have confirmed his idea .

The atmosphere in the office gradually became dignified .

Three swordsmen who have been fighting swords in the Jianghu for many years , For the first time in my life, I met a sinister black product . They decided to look for one “ Escort agency ”, For the private operation in the cotton era “ Guard dart ”.

A thousand li escort

There is only one winner on the battlefield , It must not be a black product . The network black production mentioned by Xia ideal , Why did it become the nightmare of private operation in the cotton era ？ Actually , With the growing prosperity of private Ecology , Under this huge ecosystem, there is also a black industrial chain , Absorb nutrients by any means . Malicious brush list 、 Hire robots 、 Rob stamps 、 Junk registration …… As long as there is something profitable , They all pour out . For the cotton era , Once the membership system is mixed with black production users , Not only did 100000 gift packages get washed away , And a lot of marketing expenses 、 The continuous superposition of operating expenses , It also hurts the experience of ordinary users . “ All these are the consequences that the brand cannot bear .” The three swordsmen are aware of the serious impact of the black industry . here , The other side of the city , Yaolingpeng also pondered in front of the screen “ Private domain security ”.

Yaolingpeng is the person in charge of Tencent's private domain security . The days to come , He will be a private operator in the cotton era “ Bodyguard ”, Escort every activity . Tencent , It is the Three Musketeers in the cotton era who have been looking for a long time “ Escort agency ”.

2021 Beginning of the year , By chance, the three swordsmen met yaolingpeng , The four hit it off , Made a quick appointment for a meeting .

In a conference room of less than ten square meters , Packed with teams from both sides . When yaolingpeng shared the accident cases of some enterprises , Everyone laughed without saying anything , Because these are the painful lessons they have just experienced ,10 The scene of ten thousand gift bags being sold out is still fresh in my mind .

When yaolingpeng showed the relevant technologies and capabilities of Tencent's private domain security , Xia ideal finally couldn't help it , Clap your thigh and say ,“ This ability is what we urgently need ！

” Yaolingpeng has been deeply impressed by that meeting ,“ Both sides have gained a lot , There is a feeling of regret for meeting each other late .”

The two sides had a good talk , It strengthened the determination of the three swordsmen . They decided to give the cotton era near 400 Ten thousand members “ Take a shower ”, Eliminate invalid and false users . This process , It can be understood as “ Curettage poison ”.

Curettage poison

Poison enters the bone , When a broken arm makes a wound , by the roots , This disease is eliminated . The difficulty of cleaning the membership system , No less than Hua Tuo's scraping bones and healing poison for Guan Yu . How to accurately identify true and false users ？ Once a real user is killed by mistake , It will have a serious impact on consumers ; Once the fake user cannot be identified , Black production users will proliferate in the member pool like bacteria . Grasp the scale , Become the primary problem of the moment . “ The tried and true scheme in the past , Failed in front of enterprise customers .” Yaolingpeng suddenly realized the problem —— It should be debugged with the cotton era , To explore the optimal solution of the effect .“ We all have the capabilities and algorithms for private domain security , But practical application is another matter .” According to Tencent's own black production database and its model , And millions of members in the cotton era 、 Comprehensive assessment . Rank according to reputation value , Five grades from very poor to excellent , Provide operational risk early warning respectively , It solves the problem of judging scale . meanwhile ,400 Ten thousand members is not a small amount , This also puts forward higher requirements for the accuracy of the recognition algorithm . Soon , Yaolingpeng found Wang Qing, a technical expert who has been rooted in the front line for many years , Look for solutions . After intensive and repeated debugging , Tencent and cotton era have jointly built an algorithm library , And finally filtered the approach 10% Malicious traffic and hacked accounts . “ We don't have to call the users one by one to judge .” Xia idealized jokingly . Complete in just one month 400 Data cleaning of million members , Yaolingpeng and the three swordsmen were overjoyed . However, we did not relax our vigilance , because A test “ Treatment ” The effect of “ Final examination ” Coming soon .

Attack the black industry

A good keeper , The enemy did not know what he was attacking . The time came to 2021 year 3 month 8 Japan , The temperature in Shenzhen has risen to more than 20 degrees . The great promotion activity of the cotton era is about to start , This is also the first test of the membership system after filtering and grading . The three swordsmen have a string in their heart , Looking at the screen with a serious look , Seems to want to see through , At the other end of the screen, who is participating in the activity . Whether the network black industry can still achieve its wish ？ Yaolingpeng is also a little nervous , After all, time is so tight , No one is absolutely sure whether the cooperation can achieve the expected results . He and the team keep an eye on the background data , Once an exception is found , Attack immediately . Time goes by minute by minute , The data rose steadily , The users of black products are blocked outside the door , No abnormal access is found in the background . Everyone finally breathed a sigh of relief . “ We want this steady happiness , Don't fake the carnival .” After the event , Team integration “ Reduced Edition ” and “ Efficiency ” Business value accounting , It is found that the activity conversion rate has 10%, The opening rate of SMS has been improved 5%, The repurchase rate has also increased significantly , Effective activity traffic increases by nearly 200%, It can increase income by tens of millions or even hundreds of millions of yuan every year . “ They often say that security construction can reduce costs and increase efficiency , Now I have finally seen ”, Xia ideal looked at the data on the screen and said .

All the people in the world are for profit , The world is bustling for profit . “ Member cleaning ” It is only the first step of cooperation between Tencent and the cotton era , It is also an epitome of private domain security . As the private ecology becomes more and more lively , Member operation safety 、 Content security 、 Brand protection is becoming more and more important . “ Only a solid security line , Enterprises can safely tap the huge potential of private domain traffic .” Yaolingpeng is well aware of the important task shouldered by himself and his team . The sneak attack of the underworld will not stop , The secret war in the Jianghu will not end .
