Text Chapter 56 The First Battle

Opening the mailbox, Liu Xiao saw the new email, and the attached was the virus sample that Wei Gang said, which was very small, only more than 20 K, but Liu Xiao didn't dare to underestimate its destructive ability, he directly downloaded the virus to his virtual system.

Liu Xiao turned on the monitor he made, and then ran the virus, and the monitor could record every move after the virus was run.

As soon as it was running, the virus alarm of Liu Xiao's real system sounded, indicating that a virus was trying to invade.

"Huh?" Liu Xiao was surprised, the real system and virtual system on his computer were set up by him in LAN mode, it seems that this virus has the function of automatically detecting LAN machines, and then looking for vulnerabilities and waiting for opportunities to spread. It's just that the security degree of my real system is very high, and the vulnerabilities in the system, whether they are published or unannounced, as long as they know it, they have patched it, or they have taken preventive measures, it should not give the virus any chance to invade, but the alarm still alarmed, that is, the virus uses a vulnerability that Liu Xiao does not know.

Fortunately, Liu Xiao's virus alarm discovered the spread of the virus, otherwise if his real system was infected with the virus, it would be a lot of fun, it would be like dying before he got out of school, and Liu Xiao didn't know whether to save his machine first or study the virus first. Wiping the cold sweat on his head, Liu Xiao said in his heart that this ufeifan really has two hits, and he should have a lot of unknown loopholes in his hands, so he gave himself a dismount.

Calling up the records of the monitor from the virtual system, Liu Xiao found that the virus of ufeifan is no different from the current ordinary virus, and even the destructive ability is not as good as the patchwork virus last time, but it will be difficult for ordinary people to get rid of it after being poisoned.

First of all, the virus generates an auto-executable file in the root directory of each drive letter on the computer, and the virus will be automatically executed whenever the user accesses the disk. The principle is very simple, the virus uses the system's autoplay function, this function we usually use, for example, we buy a DVD disc, after the disc is put into the optical drive, after a while, we find that the playback directory of the film will automatically pop up, at this time we only need to select the film we want to watch or a certain chapter. The reason why this playback directory pops up on its own is that it uses the autoplay function, and a file is pressed in advance in the disc, and in this file, it is specified that the first thing to be executed when reading the disc is the playback directory. As for viruses, it is stipulated in advance that the virus program must be executed first.

It is not difficult to solve this virus, as long as you turn off the autoplay function of the system, and then delete the self-running files under the drive letter, and find the virus program, delete it together, and it will be solved.

But ufeifan is not so stupid, his virus program and the self-running file are hidden, and the virus forcibly modifies the settings of the system, so that the poisoned user can not turn on the system's "view hidden files" function, that is, you know that there is a virus, you can't see it, you can't find the virus, and it is impossible to talk about deleting the virus. Moreover, the virus also has a self-protection function, which is bundled with the system's service process in the background.

After doing all this self-protection, the virus begins to secretly download various secret theft Trojans in the background, waiting for opportunities to steal users' secrets. If the virus detects that the infected computer is on a local area network, it will start to detect other computers in the local area network, and if there is a vulnerability on other computers that is exploited by the virus spreading, the virus will automatically infect it. One to ten, ten to hundred, and soon a lot of computers will be infected.

"It seems that this is it!" Liu Xiao patted his head, there is really nothing unusual about this virus, now as long as it is a virus, it almost has these functions, and the only thing that Liu Xiao can see is the vulnerability that the virus exploits when it spreads on the local area network.

But now Liu Xiao can't take care of studying that loophole for the time being, what he has to do is to hurry up with a special killing tool, and he wants to preempt Wei Gang.

Fortunately, this ordinary virus is easier to remove, Liu Xiao is also familiar with a special killing tool, he accurately found the hidden location of the virus according to the records of his monitor, and then designed a series of functions, restore the normal settings of the system, turn off the autoplay function, and finally remove the virus in one fell swoop.

After compiling the code and compiling it into an executable program, Liu Xiao quickly logged in to the Terminator forum and prepared to release his own killing tool.

To his surprise, someone in the forum had already released a killing tool, and the ID of the poster was, of course, Wei Gang. The forum is very lively at this time, and the number one person in the domestic anti-virus industry, the hero "Feng Qingyang" Wei Gang, suddenly appeared in a small civil anti-virus forum at this time, which is far more interesting than the killing tool that Wei Gang just released, and everyone is speculating about the purpose of Wei Gang's move.

Liu Xiao smiled bitterly, Wei Gang was demonstrating to himself, it seemed that he had lost to Wei Gang for the first time.

But there is nothing surprising about this, Wei Gang has done anti-virus work for many years, and the technology has reached the point of perfection, and this virus of ufeifan is no different from ordinary viruses, and it is natural for him to win Liu Xiao in terms of speed.

Scratching his head, Liu Xiao was a little embarrassed, I don't know if I want to release this killing tool I made, if I don't release it, I've already done it, and if I release it, it won't work.

After thinking about it for a long time, Liu Xiao decided not to send it, and took the initiative to take a step back, even if he admitted defeat in the first battle. "It's nothing, this is just the beginning, the show is still to come, then ufeifan will definitely not be just such a little ability!" Liu Xiao laughed at himself, he estimated that ufeifan released this painless virus first just to explore the depths.

After closing the webpage, Liu Xiao turned around and opened the monitor record again, since he had already lost, he would study the loophole with peace of mind. Liu Xiao was very puzzled, he really had a lot of unannounced system vulnerabilities, but why did he miss this one.

Now Liu Xiao's own killing tool finally came in handy, he cleared the virus in the virtual system, then reopened the monitor, and put the virus sample into the virtual system again, this time he wanted to see what detection messages the virus sent to his real system.

After running the virus, soon, the alarm in the real system went off again.

Liu Xiao terminated the operation of the monitor, and the data records obtained this time were more detailed, Liu Xiao searched carefully in it for a long time, and finally found the relevant data.

"Huh?" Liu Xiao frowned and looked at it for a long time, what kind of vulnerability is this? He knew the functions of the system well, but he couldn't even see that the spy message sent by the virus was probing which service in the system was a vulnerability.

In desperation, Liu Xiao had no choice but to clear the virus again, and then switched to the virtual system himself, and sent a detection message to the real system that was exactly the same as the virus, and soon, Liu Xiao got the return message, but this information made him a little dumbfounded.

What is returned is the version number of a plugin, the X?x version of such and such a plugin, followed by the manufacturer and publisher of the plugin: PPPLAY.

"*!So that's it!" Liu Xiao finally reacted, the vulnerability exploited by the virus is not a system vulnerability at all, but a vulnerability in the software of online TV. Liu Xiao usually doesn't have any hobbies.,I just like to use network TV to watch live football games.,This plug-in with the loophole is from the network TV software PPPLAY,It's a plug-in developed by PPPLAY in order to maximize the download speed of users。

"ufeifan, this guy is really ......" Liu Xiao doesn't know what words to use to describe this ufeifan, now Microsoft's speed of patching vulnerabilities has increased a lot, and it is becoming more and more difficult to find new system vulnerabilities, among which there are even fewer that can be directly exploited by hackers, this ufeifan is too smart, and he turned his attention to those computer standing software. For his 100 million, ufeifan really put a lot of effort into it, and it is estimated that the white hair of that guy can grow a lot.

Two hours later, Liu Xiao boarded the Terminator forum again, and found that the forum was not deserted at this time, but became more lively.

After the news of Wei Gang's appearance in the Terminator forum came out, it attracted a lot of excitement, especially several major antivirus software providers in China, they were very strange, Wei Gang obviously has his own proprietary anti-virus news publishing platform, why did he go far away to the civil anti-virus forum to announce this special killing tool. These antivirus vendors are rushing to update their own virus databases while waiting for the rest of the story.

Liu Xiao didn't dare to be too public, so he secretly followed a post behind Wei Gang's ass, and didn't dare to say anything about the loophole directly, but first praised Wei Gang, saying that Wei Gang's technology was very superb, the analysis of the virus was very accurate, and the killing tool was also very effective.

Liu Xiao directly named PPPLAY in the post, he analyzed the reasons for the plug-in's vulnerability, and the harm caused, and also released the patch he designed. At the end of the post, Liu Xiao didn't forget to advertise his studio: "There may be many starting points, but there is only one end point, Kuaiyun Studio, the end station of all security issues." ”

Everyone was staring at the forum, Liu Xiao released such a post coldly, and suddenly exploded again. In fact, no one has seen the virus that Wei Gang said, everyone wants to see it, but as soon as Wei Gang's special killing tool came out, several major antivirus software followed, and even if the life of the virus was completely ended, it is estimated that no one will encounter it in the future.

Now Liu Xiao has come out, analyzed and dissected the virus, and praised Wei Gang, but the final conclusion is that there are serious loopholes in PPPLAY, the boss of the domestic network TV industry, and where are the people on the forum willing to believe it, especially the advertisement behind Liu Xiao, which greatly stimulated everyone's nerves. So many people scolded Liu Xiao in his post, saying that Liu Xiao was dragging the dragon's tail to the sky, and he wanted to be famous and crazy.

Such a fuss, the news soon spread to PPPLAY, the previous slow response PPPLAY company, today but I don't know what kind of wind is pumped, but the speed on the homepage of their website issued a serious statement, claiming that their software has no security vulnerabilities, let alone cause losses to users, 'probation' post is pure rumor and slander, PPPLAY company will reserve the right to pursue the legal responsibility of 'probation'.

Liu Xiao was very depressed, he was already a man with his tail between his legs, and he was still a good person, why he was chased and beaten like a street rat, he really couldn't figure it out.

At this time, something happened that made Liu Xiao even more depressed, Wei Gang reappeared on the Terminator forum and issued a post in support of 'probation', saying that the virus did take advantage of the vulnerability of the PPPLAY software to spread. Shortly thereafter, PPPLAY deleted the statement on its website and instead informed users on the official forums that the vulnerability did exist, but it was by no means as powerful as it was claimed, and PPPLAY would fix the vulnerability in the shortest possible time.

"*!" Liu Xiao is indeed a little angry, just because he is a nobody, the bald head of the city government humiliates himself who came to remind him kindly; just because he is a nobody, everyone can say that he is dragging the dragon's tail to the sky; just because he is a nobody, other people's mistakes can also become their own sins.

Liu Xiao sat in front of the computer, his face pale, "One day, I will let you all know who I am!", Lan Shenghua once said that the names of the hacker circle are all false, but what Liu Xiao saw at this time was that the name was a real thing.
