Become the richest man in the world starting from the rebirth of college entrance examination

Zhou Hao is not a hacker and does not know much about technical attacks. What he is looking for is an opportunity to take advantage of the crowd to explode the bar again. However, Q Bar does not hesitate to sacrifice user experience for defense, which makes Zhou Hao feel unable to start, until he notices that Q Bar The in-site message function of the bar.

The on-site message function was actually the first one designed by Tieba. It is a simple instant messaging function developed based on Tieba, allowing Tieba friends to communicate privately. This function is very simple and very practical.

Because users’ information interaction in Tieba is public and one-to-many, when they choose to post in a Tieba, it is equivalent to opening the post to this Tieba user, or even all Internet users. If they meet like-minded friends, if If they want to communicate privately with a certain bar friend, they need a public-to-private process. In-site messages solve this problem.

When Q Bar was working on the technical architecture, they also incorporated the on-site messaging function. They placed restrictions on user postings, but they did not impose any restrictions on on-site messaging.

Zhou Hao opened the on-site message function and found that the pop-up page only had two fields: recipient and content. In addition, there was only one sending option.

In other words, whether it is a verification code or you can only post once in an hour, they are all for public posts and replies on the front desk, but there is no restriction on users' private message exchanges in the backend.

Zhou Hao understands that there is a big difference between sending a letter on the site and posting a message. But for the backend and the server, it's basically the same.

Posting and sending in-site messages both test the server's ability to handle data write requests, but in-site messages have one more logic than posting, and that is delivery logic.

A piece of data is sent from user a, uploaded and written to the server. While the server records the writing, it also delivers the content to the background of user b. User b receives the in-site message data. A user prompt will be triggered first, and then a receipt that user b has received the in-site message will be sent to the server.

In short, this thing seems simple, but uploading and distributing data is very cumbersome.

Zhou Hao registered a new Q Bar account, and then used his old account to send an in-site message to the new account. If he copied the ID of the new account. When sending, paste the new ID in the recipient field and then in the content field. Quickly paste a few times as spam, then quickly hit send, then quickly move on to the next round.

Zhou Hao calculated the time and found that he could send an intra-site message within three to five seconds. If the speed was faster, the time could be controlled within three seconds.

One message every three seconds. Twenty posts per minute, what if hundreds of thousands of people post them at the same time? I wonder how long the q bar server can last?

The more Zhou Hao thought about it, the more he thought he could try it. He immediately contacted Yu Yanhui and told him how to operate it. Let him start laying the groundwork for the second explosion tonight.

After Yu Yanhui received the news, he immediately mobilized the trolls at hand and asked them to post on Tieba and Q Bar. The core of the post was to protest against Q Bar's statement that completely shirks responsibility, and to demand Q Bar to be responsible for what it had done. I apologize to all my friends.

While posting, these trolls also listed various carefully compiled evidences. For example: When copying content in Q Bar, it is impossible for one account to copy only one piece of content. They all copy a large amount of content in one account. Then change the number and copy a lot of content.

This operation left a lot of evidence, especially since Yu Yanhui's men had kept all kinds of picture evidence very completely. The sifted out evidence can clearly show how they mobilized dozens or hundreds of IDs. Anyone with a discerning eye will know at a glance the pattern of massive copying of content during the same time period. This is basically the so-called spontaneous behavior of users. At first glance, it is an organized and planned infringement.

This set of evidence is absolutely reasonable and convincing to the forum friends.

Troopers posted the post on Tieba and Q Bar. After posting on Tieba, other trolls immediately helped to upvote the post, which immediately attracted the attention of Tieba users who are currently online. The first thing after posting on Q Bar was Just take screenshots to keep the evidence, because Zhou Hao expected that Q Bar would definitely delete the post, so he prepared in advance to leave evidence of Q Bar deleting the post.

Sure enough, the Q Bar technology on duty in the middle of the night discovered the protest posts posted by Tie Bar users. Because the content was not good for them, they deleted them without hesitation. They deleted as many as they came and blocked the accounts of the users who posted them.

Now Yu Yanhui's navy has easily left behind a whole chain of evidence showing that he posted in Q Bar, but was deleted or even banned by Q Bar. If supplemented by artificial exaggeration, Q Bar's series of practices will definitely be It will once again arouse the anger of bar friends.

The loophole in the site letter has not yet been leaked by the navy. Zhou Hao wants to launch another fast and accurate blitzkrieg for Q Bar, which he thinks is impregnable. Even if the current number of people online is mobilized, it will not be enough to support his plan.

This night, Tieba and Q Bar presented two completely different situations. Each Tieba had posts asking Q Bar to formally apologize, and the attention was very high. The attitude of the friends was also unanimously supportive to the end. But on the other hand, Q Bar, In one night, tens of thousands of users, instigated by trolls, went to Q Bar and posted many posts demanding an apology from Q Bar. However, without exception, they were all deleted by Q Bar, making these users very angry.

Zhou Hao was so busy that after two o'clock he couldn't bear it any longer, so he went back to his house to sleep. He also set an alarm clock for himself at eight thirty.

……

Early the next morning, almost all the new local newspapers reported on the unprecedented event that happened on the Internet. Yu Yanhui's public relations for traditional media began to work. In addition to the local newspapers in the capital, According to feedback from Tieba friends, at least 30 newspapers across China reported on this incident today, more than half of which were the result of Yu Yanhui’s public relations efforts, and almost the rest reported it spontaneously as a hot news item. What makes Zhou Hao happy is that these local media with average influence are similar to what he expected, pointing the source of the conflict to Q Bar's infringement.

The morning news of many TV stations also carried related reports, including Beijing TV. Overnight, comments criticizing Q Bar spread from TV to the Internet to newspapers, instantly pushing Q Bar and Tencent to the forefront.

Mr. Ma, who had arrived in Beijing to participate in the Internet forum, was furious when he found out. He made more than a dozen calls to Shenzhen City. On the one hand, he severely criticized the relevant person in charge of Q Bar, and on the other hand, he asked the vice president at the base camp to do everything possible to solve the problem. Save Q Bar and the company's reputation in front of the media.

It's just that the voices of condemnation are overwhelming now, and it is difficult for all the media that have spoken out to carry out counter-public relations. The media cannot easily slap themselves in the face, so there is very little space left for them.

Even though there are so many media outlets denouncing qba, qba still has not changed its approach. They issued another statement at 9:30 in the morning, claiming that the infringement does exist, but it is entirely the individual behavior of the user. qba has closed the accounts involved and has We reserve the right to pursue legal responsibilities. At the same time, Q Bar also calls on users to keep their eyes open and not to be taken advantage of by unscrupulous elements.

When Zhou Hao heard about this new announcement, he was wearing a dark blue suit and had just driven to the entrance of the conference center of a five-star hotel in Dongcheng, where this Internet conference was held.

The conference started at ten o'clock. When Zhou Hao arrived, some of the invited participants had already signed in. Before Zhou Hao entered the venue, he communicated with Yu Yanhui and asked him to mobilize users in the post bar during the day. He first called on everyone to attend the conference at eight o'clock tonight. Click to explode the bar for the second time, but do not disclose the method of exploding the bar. Just make early adjustments to attract users to the "Tieba family", and then inform everyone on the site of the method of exploding the bar before the point is reached. .

Once Yu Yanhui's navy begins to spread the news that the Q Bar will explode tonight, the Q Bar will definitely be on standby and try its best to consolidate the defense, but they ignore that there is a small trail that can be used to sneak attack from the back.

When Zhou Hao signed in with the invitation letter, the person in charge of the Q Bar Business Department also received the news that the Tie Bar was planning to explode at 8pm. He immediately made a strict and detailed division of labor for his subordinates: the technology responsible for the server will monitor online at all times. User data changes, and be prepared to respond to traffic peaks in a timely manner; and the backend technology must be ready to implement more stringent restrictions at any time. He is worried that Baoba users will register multiple accounts to log in to break through the barrier of posting once an hour, so he also We have formulated an IP restriction strategy. Once we find that a user switches accounts to log in, we will immediately restrict the other party's IP address, and increase the limit of posting once an hour from the account level to the IP level.

For him, this battle must be fought against the attacks of Tieba friends. If the website is closed again because the server cannot bear the load, it will be really shameless!
