Chapter 250 Changes

Although the antivirus program was written, Edward found that he had encountered a very serious problem - there was no effective way to publish his program smoothly, because he lacked the most up-to-date SPAN network node distribution map. Pen "Fun" Pavilion www.biquge.info (""")

The SPAN network is composed entirely of decentralized nodes, and is not a centralized structure.

Edward remembered a previous incident, he remembered that there was a young man named Claire on the Ministry of Defense, who had the ambition to completely depict the network topology of the SPAN, but he inadvertently constantly triggered the intrusion alarms of many systems, which was strongly protested and opposed by many institutions, and the young man finally had to give up this idea.

So much so that no one now knows what the distribution structure of the entire SPAN network has become.

Edward hurriedly followed the clues in his memory to the Ministry of Defense, only to be told that the other party had already left, and they did not know where they went.

He wanted to ask if the other party had achieved certain results at that time, but he did not get any useful information.

None of the administrators had the contact information of the system administrators of other nodes, and usually where something went wrong, they were called from the bottom up, layer upon layer.

Sometimes, there are offices or laboratories at NASA research centers that have never heard of or registered to call and ask to fix a computer glitch, and these offices and laboratories are directly connected to SPAN without notifying the SPAN network office, and they don't even have a clear name.

It may be that the administrators of these nodes feel that "it will be safer if no one knows", and they are not on the SPAN network map or any list, and hackers naturally have no way of knowing their existence.

As everyone knows, these are just wishful thinking.

Edward made many phone calls, but none of them achieved his goal.

He could only write a detailed analysis report and send it to the email address of the system administrator he knew, and at the end of the email, he attached the antivirus program he had written. (《》7*

But he didn't have much hope for this, because there were not many computers working on the network at the moment, and even many members of the security team had been recruited, and they could only be contacted by phone.

His ADW antivirus program automatically detects the computers that exist on the network, and when it enters the computer, it first confirms whether the computer has been infected, if so, it will first perform a worm scan, then patch, if not, it will be patched directly.

In the report, Edward mainly analyzes where the worm will modify the computer, and the harm it can cause, as well as the distribution of the current tree worm infected.

Edward was eager to receive feedback from others and the good news that the worm had been removed by his antivirus program.

However, to his dismay, the feedback did come quickly, but instead of good news, something else happened - a new version of the worm was discovered!

The person who submitted the version of the worm variant was a network administrator named Teucer Frank from the U.S. Department of Energy.

Like Edward, Trafigura was not a formal security worker, he was only very interested in computer security issues. Internally, however, he is widely known to be proficient in VMS systems, and his official job is as a network administrator for a national laboratory funded by the Department of Energy.

After analysis, Edward discovered that the new version of the worm submitted by Tefigura was a variant from the previous one, with several improvements, and it seemed that it was released only later after improvements were made to address the shortcomings.

As a result, Edward's ADW antivirus program is completely useless, because he used one of the worm vulnerabilities in a clever way, but now the other party has fixed it, so his antivirus program is meaningless.

Edward wasn't sure if there were any other new variants on the web, but it seemed very likely at the moment. Templar

Things are back to square one, much to Edward's dismay, and he calls Todd to hear some good news. There are very few people in the real security team who can really make a difference, and others may have their own unique skills in programming or hardware, but in the field of VMS security, none of them are as good as Edward, but fortunately he later joined a Todd.

"Hello, I'm Edward, and I've emailed you before."

"Hello. I read your analysis and it's very well written. ”

Although Edward's analysis report was not officially released, it was sent to some people in the group, and although it is useless now, it can at least let others know that he has done this work.

"Thank you." Being recognized by his peers, Edward's frustration eased a little, "But my work doesn't make any sense anymore, I just re-analyzed the new version, it seems to be a brand new worm, and it's more powerful than the old version, with fewer shortcomings." ”

"You're right. Just now, I discovered a new variant here, and this is the third type known so far. ”

"Really?" Edward was stunned, "How did it come out so quickly?" The speed at which we kill viruses is nowhere near as fast as the speed at which the other side can release worms. Do you have to disconnect the entire span? ”

Edward shuddered a little at the thought of this situation.

The SPAN network has suffered its biggest crisis since its inception.

If all of them were to be disconnected, it would cause incalculable damage, and the entire United States would be stagnant as a result, and both scientific research, military and economic losses would be enormous.

However, it is also an unacceptable fact that the mastermind behind the scenes, who is secretly hiding behind the scenes, is constantly stealing classified information from the United States.

While new members are constantly being added to the security team, this is completely to no avail.

This new worm is beyond everyone's understanding, as if it is beyond the computer technology of this era. It's like when they're still in the era of slash-and-burn farming, and suddenly they're confronted with robbers and robbers armed with hot weapons.

Although Edward believed that the worms would be cleared sooner or later, it would take time, and they would have to fully grasp all the secrets of the worms before they could proceed.

But by that time, perhaps the Tree Worm had already completed its mission.

"Man, maybe it's not that bad." Todd heard the frustration in Edward's tone and immediately comforted.

"I'm sorry, I'm a little out of shape."

"I understand." Todd continued, "I mean, it's not as bad as it seems. I've read your analysis report, and you mentioned that the entire southern part of the Federation, with the exception of a few nodes that have actively disconnected from the network, has been attacked by worms, but as far as I know, that's not the case. ”

"Really?" Edward was stunned for a moment, "The data in my report is completely based on feedback. How could there be a mistake? ”

"Many of the places you mentioned in your report that have been disconnected are still connected to the network, and they don't even know that the entire SPAN network is being subjected to unprecedented worm attacks, such as Radar Lab in California, Fermilab, the Lawrence Livo Research Center in the East, and ......"

Todd named several important institutions and labs, and the network was working very well at the moment, and Todd had friends who worked there and had been contacted by email or phone, and they didn't even know anything like this was happening.

However, in Edward's report, these nodes either actively disconnected from the backbone network, or theoretically, should be completely overrun by the tree worm.

"It can't be!" Edward retorted, "Elsewhere I've inferred from the contributions of their surrounding nodes, but I'm sure I'm completely infected in Fermi Lab, because their system administrator, Anthony, had called to report the malfunction. ”

Although Edward had never known of Anthony's existence before, he was very impressed with the foul-mouthed guy. At that time, after he received a call from the other party, he was immediately scolded by the other party, and the scolding was bloody.

"Really? That's weird. Todd was also puzzled, "I have a former colleague who works at Fermi Labs, and I was on the phone with him ten minutes ago, and the other party said that everything was working on the Internet. There's no way he's going to lie to me, and you're telling the truth, so there's only one possibility left, and that's that they may have been infected with worms before, and then recovered quickly. ”

Todd's words moved Edward's heart.

Could it be that there is a master in Fermi Lab who has found an effective way to kill worms?

After Edward and Todd ended the call, Edward immediately dialed the number of Anthony, the administrator over there, and he was glad that he had left a mind and wrote down the other party's number.

The first time the call was called, no one answered, which made Edward a little anxious.

He hung up and dialed again, and this time, after waiting three times, the phone was finally picked up.

"Hey, I'm Edward from the SPAN Cybersecurity Response Center, and I'm looking for Administrator Anthony."

"I'm Anthony. Edward, it's you, why are you calling me now, and don't look at the time, I'm about to get off work. The earpiece reminded me of Anthony's thick voice.

Work? Edward was slightly stunned, he looked at his watch, indeed, it was ten minutes past the normal off-duty time, and according to the usual schedule, it was indeed time to get off work.

But aren't these extraordinary times?

Confused, Edward asked, "Hello, I would like to ask, how is the situation of your lab's network now?" ”

"Network? Oh - did you call specifically to ask about it? Our network has been restored, I didn't expect your efficiency to be so high this time, haha, it seems that I shipped and scolded you to still work! Nothing else, except that there were some important servers that were inaccessible, and I called over there, and it was said that I had a virus. I think they should ask you to go over and check it out......"
