The nmd virus is one of the most difficult viruses to deal with in the world. It spread around the world in 2004 and is a highly transmissible malicious virus. It mainly attacks servers through emails, but at the same time it can also attack servers through instant messaging tools such as md
"It can be infected through emails, instant messaging tools and "ftp programs" at the same time. For
The server "nmd" spreads in a similar way to the Code Red virus, that is, by attacking vulnerabilities in the server program. Because the virus occupies a large amount of network bandwidth and internal computer resources during its own infection, the networks of many large enterprises have been affected.
It will have a great impact, even paralysis, and the speed of personal PC will also be significantly reduced.
Moreover, when the "nmd" virus sends infected emails, users will also be infected with exe files. At that time, anti-virus companies that claimed to be able to deal with the virus all used the method of deleting infected files to kill the virus, causing many important programs to be unable to run, causing extremely serious problems.
Bad consequences.
I originally thought that nmd virus is mainly an attack-based virus program, and hackers would not use such radical means to show their stupidity, but he doesn't seem to think so. He actually designed a virus program that is mainly based on nmd virus.
A mutant virus bomb program, his method of designing a password barrier is really weird and novel. It not only functions as an attack, but also has a defensive function. At the same time, it also confuses her to keep circling around and doing useless work.
This time, the operation of the command became extremely smooth. Looking at the string of characters that kept beating on the screen, a smile gradually appeared on the corner of Yao Xiaojing's mouth.
However, about twenty minutes later, the originally relaxed atmosphere became tense again.
"Isn't it nmd? Is it another virus? A new virus that we have never been exposed to before?" Tan Xiaowei first became unconfident about herself.
Yao Xiaojing kept moving her hands and denied without raising her head: "It's nmd, but it's the latest variant of nmd. This is the first time I've encountered it."
After being affirmed, Tan Xiaowei's expression softened slightly. She frowned and stared at the screen where the decoding program had been tracked several times without success. She was puzzled: "Aren't all the viruses removed? Why is the decoding program ineffective?"
?Did we overlook any details?"
Yao Xiaojing also shook his head, "I'm also confused. Logically speaking, after the virus is cleaned, the decryption process usually takes no more than ten minutes. But after trying it several times, it stuck on the screen for more than three minutes. What went wrong?
I also checked and upgraded the decryption program, and there are no problems, but it is still stuck in the same time period. Which link is the problem?"
The two of them scratched their heads at each other, wishing they could take the case apart to see what monsters were hidden inside!
Only Gong Xue, who had been sitting quietly on the side, stared at the flickering screen, thought for a long time, and then carefully put forward his opinion: "Yao Gong, could it be that the virus has not been eliminated?"
When Yao Xiaojing heard this, she turned away from the computer. She frowned, as if considering the possibility of Gong Xue's opinion, "Xiaoxue, you mean..."
"Gong Yao----------" Suddenly, the director of the information center walked in. He held a wireless phone in his hand and handed it to Yao Xiaojing, "Your phone is a top-secret line."
Yao Xiaojing said oh and took it.
It's Gao Lie calling.
He told Yao Xiaojing that the location had been determined, Songjiang Park Cultural Relics Area. He gave Yao Xiaojing a deadline of 20 minutes at most. In 20 minutes, she, Gong Xue, and Tan Xiaowei would set off for the mission location.
Yao Xiaojing took a breath and replied quietly: "Yes!"
20 minutes.
For her, 20 minutes can change the world.
She put down the phone and said to Gong Xue, "Xiaoxue, this is Captain Gao. He originally wanted to talk to you, but I hung up because I wanted to know, what did you just discover?"
Gong Xue's expression was very cautious. She thought for a while and said: "I know that nmd is a vicious virus spread based on the Internet. The method of removing them is generally limited to manual online removal. I just saw that you were also operating online, and the system also prompted to delete it.
Success, but I always feel that this is like a deception, that is, the hacker actively gives you the illusion of deletion, but in fact it has not been completely deleted, so it will affect the use of the tracking decoding program in the future. I think..."
Seeing her stop, Yao Xiaojing gestured anxiously, "Don't stop, Xiaoxue, keep talking."
Gong Xue's face turned a little red, "I'm just guessing, it may not be useful."
"Say it quickly, I'm so anxious!" Tan Xiaowei couldn't hold back her anger.
Gong Xue closed her eyes, as if she had made some kind of determination, and seemed to encourage herself. She paused and said, "I suggest you try to clear the virus offline, that is, unplug all network connections.
Even turn off the indoor WiFi and try it completely in a bare metal situation."
"Ah? This is the method you said..." Tan Xiaowei shook her head.
I have indeed used offline cleaning methods to delete viruses, but those are viruses that can be infected and spread by running on a single machine, rather than malicious virus programs whose virus technology is based on the Internet and has a wide range of transmission channels.
Gong Xue immediately moved her hair with her hands in embarrassment and explained in a low voice: "I also have a guess. Because I have discussed this issue with a professor at the university before, and he told me that the reason why some viruses are difficult to crack is actually very simple.
, just don’t play by common sense. People always think that the necessary method is feasible, but they always hit a wall. It is better to open up your mind and try the opposite method, maybe you will find the key to open the door."
"Yes!! What you said makes sense, Xiaoxue!" Yao Xiaojing felt her eyes suddenly light up, and her dull and depressed head seemed to be illuminated by light instantly.
Thoughts are immediately put into action.
Soon, all that was left of the laptop was a bare machine, and even the power cord was unplugged.
Yao Xiaojing looked at her watch, recited a number in her mind, and then typed a series of characters on the screen again.
Gao Lie had been standing at an elderly chess stall for a while.
They are all elderly people in their 60s and 70s who have little sleep and find it boring to go home, so they are reluctant to leave the square late at night.
The Songjiang Park Fitness Plaza has obviously passed its liveliest period, but the scattered groups of people still exercising and dancing in the square still add a lot of charm to this largest square in the region.
Gao Lie turned his attention to the tall wall more than ten meters away.
The blue brick eaves and tiles, hidden under the lush old trees, look particularly heavy and majestic...
Inside the wall, a gilt copper bell made an ancient and distant sound in the night wind, adding a mysterious and desolate atmosphere to the dark night...
