Chapter 80: Adding Salt
After finishing working in warehouse six, Yang Qing returned to the office and opened the database downloaded from Penguin.
Although Yang Qing only downloaded the key key values, the database is still very large, and the opening speed is a bit slow.
“1%…… 5%…… 13……”
"I'm a painter, I'm good at painting, and I'm going to paint that new house more beautifully, and I'm going to finish it...... Hmm, what about passwords?"
Yang Qing looked at the open database and frowned, the key information in the database, the username and password are still a string of 32-bit strings, although they have been parsed, but none of the passwords have been parsed.
"It can't be salted, right?" Yang Qing looked at the database and said secretly: "Well, it should be salted, otherwise, with my powerful dictionary, how could I not crack a single secret, it seems that this password can't escape!"
Yang Qing still underestimated the importance that penguins attach to data, and although they use the most common MD5 encryption, they add a little spice to the real information. MD5's algorithm is public, although it can't be reversely cracked, but it can be cracked by exhaustive means, Yang Qing's previous dictionary is this method, in order to deal with this exhaustive method, it is necessary to add a string of random values to the real user information, and then MD5 encryption, so that even if Yang Qing gets the database, he can't get the secret and account of the account through exhaustive means, for example, for example, the user's password is 12345, if it is directly MD5 encryption, then the hacker is easy to compare, so if you add a random string to 12345For example, the string added after "12345+dfakjljfi3242#@*!" is the salt value, commonly known as salt.
MD5 encryption of the salted password, so that the hacker is useless to exhaustively, in order to get the real password you must know how much the salt is, and the general salting is rarely fixed, all are dynamic, every user is different, and if you want to crack the salted password, you must first know how much salt is, or the salted algorithm, and the salted algorithm is usually only written in the source code of the program, and the salt will not be stored in the database.
"Obtaining the source code of WeChat, this estimate is a bit hanging, this core algorithm must be in the hands of the highest level, and the stored computer is estimated to not even be equipped with a network card!" Yang Qing felt that his invasion this time was a failure.
"Hey, I'm really thinking too much, it seems that it can't be used to kill the penguin by hacking," Yang Qing sighed as he browsed the huge database.
In addition to the two key keys of username and password, the database downloaded by Yang Qing also had some randomly selected key values, and there were too many database keys of penguins, and Yang Qing didn't have time to look at them one by one.
"This key is the time of registration"
"This key is the last login time!"
"Well, what is this? It's also encrypted, is it an ID number?"
"Doe, what the hell is this?"
“……”
Yang Qing checked the past one by one, and suddenly Yang Qing put down the mouse, stood up, and walked back and forth in the office.
"There's not just one way to get user information, why should I fight with penguins!"
"I can't get user information from Penguin's server, I can get it from Penguin's users!"
"Haha! Why didn't you think of that just now?"
"Penguin has just been attacked, the server has been on strike for several hours, and if the user's password is leaked at this time, the user will definitely think that the penguin has leaked!"
"Haha, I'm such a genius!"
"Well!
Yang Qing said and returned to his seat and turned on the bee colony.
Line after line of commands are typed in the blackened console.
"Looking for Android ......"
"Looking for WeChat client ......"
"Looking for QQ client ......"
"...... in broiler statistics"
"The statistics are complete, and the current number of bee colonies is 1.24 million+"
"It's too little, and there is at least 100 million data to make netizens believe!" Yang Qing said secretly.
The botnet controlled by the hive is mainly computer-based, and the bee colony on the mobile phone is only 1.24 million, which is far from Yang Qing's requirements.
"Smack...... Syllable...... With the sound of keyboard tapping, Yang Qing changed the invasion target of the swarm.
"Lock the colony target: mobile"
"The number of bee colonies is 200 million"
"Lock the IP group for China"
"Load the vulnerability library!"
"Intrusion mode is fission"
"Fission mode is being switched......
"Mode Switch Completed ......"
As Yang Qing changed the configuration of the bee colony, the number of bee colonies on the console began to increase geometrically.
Mobile phones and computers seem to be two different devices, but their operating systems are basically the same, the difference is that ordinary users on the computer basically use Microsoft's system, while the kernel of the Android system on the mobile phone is based on Linux, Apple's iOS system is based on the UNIX system, for Yang Qing, who has a general vulnerability, there is not much difference between hacking a mobile phone and hacking a computer.
After setting the strategy of the bee colony, Yang Qing looked at the time, it was already past the end of work, and it would take time for the bee colony to develop to its predetermined goal, and it was estimated that it would have to wait for tomorrow.
"Let's get off work on time today, I haven't accompanied Sissi to go shopping for a long time. Yang Qing thought in his heart and turned off the hive's console, although the console was closed, it would not affect the hive's self-operation.
Walking out of the office, most of the people in the company have left, and there are still many people working overtime, Yang Qing glanced at the company, and then came to Chen Qian's office, pushed open the door and shouted: "Sissi, get off work!"
Chen Qian, who was sitting at the desk, raised her head and saw Yang Qing pulling the door, and couldn't help but smile and said, "Yo, I actually got off work on time today!"
"Do you want me to go shopping with you?" Yang Qing asked.
Chen Qian heard this: "Really?"
Yang Qing nodded and said, "Hmm!"
"yes, let's go!" Chen Qian stood up as she spoke.
"Aren't you going to clean it up?" Yang Qing said.
"Pack up, hurry!" Chen Qian urged.
Penguin's servers are back to normal, but they are not stable, the presence of ghost bees has affected many of Penguin's servers, especially game users, disconnections, high latency and so on, although the number of people affected is not large, but angry players still blow up Penguin's customer service calls.
Weibo, Moments, and major news media have reported on the attack on the Penguin server this time, and all kinds of comments are fermenting on the Internet, just when people are speculating about what is wrong with the Penguin server, a message pops up on WeChat.
