For this ransomware virus, she took the initiative to say it, and she tracked down abnormal spam on the Internet, and then found such a thing. Pen % fun % Pavilion www.biquge.info

Although the current software experts say that WannaCry is weak in attack, the computer will fall into an asymmetric high-strength encryption state after infection, which means that it can only be prevented and cannot be cracked. Her esteemed administrator did not give such an order.

Xia Yu is not interested in being a savior for such a virus, on the contrary, he can still use it, and he has already done so.

"We can't solve this WannaCry virus, but it has a limited effect on our company's network products, and it is basically infected with internal LANs."

In a small conference room of Company E, a middle-aged man with glasses is talking in front of a slideshow.

"A colleague in the UK discovered that the ransomware was trying to get into a very special, non-existent website, and he paid £8.5 to register the domain name, and since then the further spread of the ransomware has been stopped."

"According to our analysis, this strange URL is likely to be a "checkpoint" set by the ransomware developer to avoid being caught by network security personnel, and the act of registering the URL inadvertently triggers the program's built-in 'suicide switch', that is, the ransomware virus has to visit the non-existent URL before each attack, if the URL continues to exist, it means that the ransomware has not yet attracted the attention of security personnel, and can continue to travel unimpeded on the network; and once the URL exists, it means that the virus may be intercepted and analyzed. ”

"Does that mean we've found a way to deal with this virus?" A supervisor in the audience asked, but it was clear from his tone that he was not a technician.

"I'm sorry, we still can't do anything, because the virus has mutated, and this method is only temporarily preventing the further onset and spread of the ransomware, but it can't help those users who have already had a ransomware attack, and it can't completely crack the ransomware."

The expression of the man with the eyes is very pity.

"And according to the urgent report of the Network and Information Security Information Notification Center: monitoring has found that there is a variant of the WannaCry ransomware virus that has broken out around the world: WannaCry 2.0, which is different from the previous version, this variant cannot be closed by registering a domain name, and the variant may spread faster."

"But this kind of loophole also gives us a direction to study, and maybe it won't be long before we can figure out a solution to the problem."

"It won't take long? How long was that? The executive's choking made the eyed man on the stage very embarrassed.

"Alright, let's get out of the way! Although it is a headache for such a thing to happen when the company's new product is launched, it does not have much impact on us, and we are instructed to go down and do a good job in the protection of the internal network. ”

"Send someone to contact us and say we're willing to buy their company for $10 million."

Ten million? It's a bit of a slap in the face, you have to know what the valuation of Dayu Technology was before, but the reality is stronger than people, as the upper hand, they are not afraid of what bubble Dayu Technology will turn out.

But at this moment, a red light suddenly appeared in the dimly lit conference room.

What's going on? Brad, who was talking to his subordinates, was a little puzzled, because of the success of the superflip, his position has been promoted to the next level of supervisor, and he has the right to make decisions on some things in the company, which is why he wants to spend money to buy Dayu Technology.

The man with the eyes on the side is the chief engineer, and the one who choked him was naturally a wine bag and rice bag that had just taken over Brad's position, he didn't understand anything, but he had to interject everything, but he still understood English words.

I saw that he was a little short of breath and pointed to the screen behind Brad, and a word popped out of his mouth - "WannaCry", his eyes were full of disbelief.

“What？” Brad, who couldn't understand it, turned his head with a question, and then he seemed to see a ghost, and the red pop-up window of the ransomware virus on the screen, which was originally illustrated, had taken up the entire screen, and the numbers of the time recorder on it were also beating second by second.

How do you look like you have been hit by a ransomware virus, is today April Fool's Day? "Ding Ding Dong ~~Bang Bang~~" The next second, the mobile phones in everyone's trouser pockets rang at the same time.

Today is not April Fool's Day, April Fool's Day has passed the day before yesterday.

At this time, the melon-eating masses who had just uninstalled Yi Translate and installed the super flip found that the super flip on their mobile phones could not be opened, and computer users found that their computer screens were full of blood-red pop-up windows.

Then almost all types of files such as photos, pictures, documents, compressed packages, audio, videos, executable programs, etc., are uniformly modified to ". WNCRY”。

Countless people who have been recruited are wailing their D disk, E disk for many years of treasure, those "memories of youth" can never come back, it is really a man who will be silent when he listens, and a woman who will cry when he listens, it's just a dog.

It's no longer WinXP.,Even Win7,Win8,Win10 was tricked (please don't substitute it with reality.,Really,Seriously, you'll ^_^ lose),They all have one thing in common without exception.,That is, they all installed super flip not long ago.。

In an instant, the Internet was exploded again, and the spearhead was pointed at Company E in the center of the whirlpool.

"What's wrong with Company E, didn't you say that this virus only infects users who don't patch, how did it become like this?"

"Company E raised by dog food, Lao Tzu has reinstalled the system, don't think I will use your products anymore."

…………

On the stock market, Company E's stock plummeted, evaporating billions of dollars in an instant, and only a few million users were recruited, but the number of computer users tripled. Even Mark was shocked, he didn't expect the virus he changed to have such an effect, he didn't know it himself.

Of course, the ransomware can't break through the firewall of Company E, and it can't be infected with the patched new version of the Win system, but who let him steal things, who let him obviously be a pirate and ride on the genuine head to pull shi! It's a bit too much, and it's going to be cleaned up.

But Xia Yu didn't shoot directly.,The hacker named Mark was discovered by the Red Queen when he was spreading unwanted software containing virus links.,It's very early.,So the source code program provided by the Red Queen was modified to be more suitable for the invasion of this software.,You can't get in, I'll take a ladder to help you in.,That's how interesting。

This is Xia Yu's punishment, if you don't want to make a bigger fuss, you will directly infect mobile phone users, in this era of mobile communications, what will happen in the future will be very exciting.

Three million users, the fall of one hundred and fifty countries, tens of billions of dollars in losses are enough.

When paying attention to these news, Xia Yu was on the way back, sitting on the tour bus, Xia Yu felt very interesting browsing the posts left by angry netizens, and was pitted by the big companies they have always trusted, what kind of experience is this, Xia Yu is a little curious.

Keyboard warriors are keyboard warriors after all, and their violent pressure on the Internet is very useful to individuals, but the impact on monster-level large companies is minimal, not to mention that Company E has become a mess internally, you must know that their official website is also a red flag.

So how about giving them a higher level at this time, Xia Yu dialed Su Jin's phone.

"Hey, Mr. Xia."

"Mr. Su, let's start now!" Xia Yu's tone seemed to be saying a trivial matter.

"Yes." Su Jin took a deep breath before giving a solemn answer.

It's just a small plan, and it doesn't need to be in the same tone as announcing the completion of the human plan, otherwise what to do with the big scene in the future, Xia Yu is very clear.

In this changing April, someone found that Dayu Technology also spoke out.
