"Can I take a look at the backup hard drive?" Hu Yifei asked. 【】

The man hesitated a little and said, "Your people have already seen it before, and there is indeed no data on it!" ”

Hu Yifei frowned, can you not see it again after seeing it once, then you go to the hospital to see a doctor, the doctor asks you to pick up your clothes, you can already pick it up at home, that

Can it count?

The boss spoke at this time, "I've looked at all five hard drives, and they are basically empty, and there are two hard disks with a few files on them, and they are all there."

A long time ago! ”

"You mean there's data on it?" Hu Yifei immediately caught the clue.

"Yes!" The boss nodded, "But it's useless, and three of them are empty!" ”

"Show me those two pieces with data!" Hu Yifei said to that person.

The man hesitated for a moment, but still found the two hard disks and handed them to Hu Yifei. After Hu Yifei connected the backup hard drive, he saw the backup hard drive

, one of which has two files on it, and the other has only one file on it.

"You said that hackers emptied the data, why did they leave these few bits and pieces?" The boss asked on the side, looking puzzled.

Hu Yifei opened the hard disk test tool and looked at it, then shook his head and said: "Boss, what do you think, how can there be traces of emptying files on this?" ”

The boss was stunned for a moment, and then blocked the people of the company, "I checked, and he said that the files were all emptied, and the hackers used a high-level shredding."

way, all the files including traces are cleaned up! ”

"!" Hu Yifei knew that the boss was fooled, "Even if it is smashed, there will be traces of smashing!" You see, except for what you look at in front of you

For these few files, there is no trace of any other data writing and erasing on this hard drive. ”

The boss blushed, he just entered the industry, sometimes he knows that something is right, but when people flicker, it is difficult to hold on, anti

And think that they are wrong.

Hu Yifei turned his head and glanced at the person in the company suspiciously, and the person's gaze began to dodge a little.

"Boss, you have to have a judgment in your heart in the future, you can't follow the crowd!" Hu Yifei said, starting with the two only documents

Analysis, looking at the creation time of the document, one is in March, the other is in August, and the one in March is almost a year ago, "Boss, you."

Look, what's not there now? Hu Yifei asked.

The boss stared at it for a long time, and then shook his head, "I can't see anything!" ”

"Time! , Hu Yifei smiled, the boss still lacked a little bit of risk, "Although the time between the creation of these two files is five years apart

months, but one thing is the same, you see, all created by o o-o-oo points! ”

"Huh?" The boss spat out, "That's really the case!" ”

"Let's look at the other hard drive!" Hu Yifei switched to another hard disk, clicked on the properties of the file, and immediately said, "What."

What is it? It is also created by o point o minute! ”

The boss nodded and asked, "So what does this mean?" ”

"It shows that his backup work was carried out at o o'clock! , Hu Yifei pointed to the person behind him, "I'm not wrong, right?" ”

The man nodded hurriedly, "Yes, yes, the backup was indeed carried out at o'clock o'clock!" ”

The boss stretched out his thumb, and then said, "Then how do we check the traces of hackers now?" ”

Hu Yifei sighed, "I don't think there is any hacking at all, right?" Hu Yifei looked at the man again.

The man quickly shook his head, looking embarrassed, "I don't know about this, but if there is no hacker, why not the data I have backed up."

See? ”

"Can you take a look at the numbers? , Hu Yifei pointed to the three files on the hard drive.

The man was a little embarrassed and said, "These are the company's customer data, and no outsiders can read it without our boss's approval!" ”

"Then you can call your boss!" As soon as Hu Yifei mentioned the word boss, he couldn't help but think of Lao Sao, a little embarrassed, and said: "

I think your boss is also very anxious to know where all the backed up data has gone! ”

The man thought for a moment, bit it, and said, "Okay, I'll call the boss." After speaking, he picked up the phone and went to the side to call,

After a while, he returned and said, "The boss is in the company now, and he will come over in a while!" ”

"Then wait!" The boss sighed, he was busy talking all day, and nothing appeared, but as soon as Hu Yifei came, he immediately appeared

One, clue, it seems that he is still far away. The boss didn't know that when Hu Yifei was in Weilan, he was picking up Qigu every day

Strange, those government agency computer failures, that's called variety, more bizarre and tortuous, everywhere, Hu Yifei is hard

cultivated.

After waiting for less than ten minutes, the boss of the company came, and at first glance he was a very shrewd and capable person, slightly blessed, and came in and went straight to Hu

Yifei and the boss, "It's so late, and I have to work hard for the two of you, I'm really sorry!" When it's over, I'll have a supper! ，

"You're welcome! , Hu Yifei smiled, "We're ashamed, it's been a whole day, and we haven't figured out the reason for your normal work!" ”

，

"That's too modest, who doesn't know Figo's reputation now!" The boss smiled and took out his business card, "No, Sun Dashan, exactly."

The boss of this company! ，

The boss hurriedly exchanged his business card, Hu Yifei didn't go out this time to do business, so he didn't bring his business card, but politely accepted it

Finish.

"That's right, Mr. Sun, because this server has been formatted and the system has been reinstalled, so you want to find me from this server again

Clues are very difficult, so I want to take a look at the data of the files on this backup hard drive and see if I can get some clues! , Hu Yifei pointed

Finger to the computer

"These are a few data files that your company backed up a long time ago!" ”

"Okay, look, look!" Mr. Sun didn't mind, and when he finished speaking, he asked Hu Yifei,

"You see if our data can be recovered, hackers will admit it, the key to these customer information can not be without, business for a day

Can't leave!

"It's hard to say!" Hu Yifei shook his head, "I don't think there's much hope, but this is just a guess on my part, I have to read this document to be sure!" ”

Mr. Sun's face was a little worried at the time, what he was most worried about was that the data could not be recovered, and hacking was secondary.

"This data is encrypted!" Hu Yifei looked at the employee in charge of backup, "You should have a special data viewing tool, right?" ”

"Yes, yes!" The man nodded.

"Come on, I'll come!" Mr. Sun commanded.

The man didn't dare to delay, took out a USB flash drive from the safe, handed it to Hu Yifei, and said, "The data viewing tool is on this!" ”

Hu Yifei plugged in the USB flash drive, and there were two tools in reality.

The man pointed to the first one and said, "This is it!" ”

Hu Yifei nodded, and then ran the tool, imported one of the files on the backup hard disk, and after more than ten seconds, the data was opened, which was unexpected

To someone's surprise, there was only one piece of data in it.

"Ahh The man in charge of the backup opened his mouth wide, as if he remembered something.

Hu Yifei opened the other one again, and it was even more empty, there was not even a single record, and this guy actually backed up an empty data back

Come. The third file opens, and there is only one piece of data in it, which is a bit similar to the first file.

"The hacker deleted the number of connections?" Mr. Sun knew a little more, so he asked.

Hu Yifei shook his head, "That's impossible, the data is encrypted before it is saved, and it is difficult for hackers to unravel it; Again, hackers are

If you delete the data, you can't change the time when the file was created! ”

"So what do you think is going on? , Mr. Sun hurriedly asked.

Hu Yifei stood there and thought about it, looked at the other tool on the hard disk, and asked, "This tool is a backup tool, right?" ”

The man nodded, "Yes, this is a backup tool, and that's what I use to make backups!" ”

"Good!" Hu Yifei directly ran the backup tool and said, "You set it up now, and I'll see how you backed it up before!" ”

The man walked to the computer, took a deep breath, and began to set up the backup software, and the backup time, he chose the o-o-o-o

When it was time to choose what to back up, the man was suddenly stunned and couldn't stop standing there. There are only two options above, one is

"Backup

All content", and the second is "Back up the content of the day".

Hu Yifei patted the man's shoulder, "Okay, don't choose, the problem has been figured out!" ”

But Mr. Sun and the boss were still wondering, and they said how could they figure it out.

"What the hell is going on?" The boss hurriedly asked.

Hu Yifei looked at Mr. Sun, "Your backup staff is indeed very diligent every day, and they also strictly follow the company's articles of association to do things, but it is too big."

Meaning. Hu Yifei paused and sighed: "He chose to back up the data of the day, that is, the newly added data in the database on this day, which is today."

The data has increased compared to yesterday, but he chose to back it up at o'clock in the middle of the night. At that time, how could anyone work in the company, compared with the number of databases

Yesterday is the same, that is, for a year in a row, you have been backing up empty data. ”

Mr. Sun was dumbfounded, "This won't be, right?" ”

Hu Yifei spread his hands, "I suggest that you better check the backup data of the financial system as well, so as not to have any accidents!" ”

Mr. Sun glared, and the man quickly took out the other five hard drives in the safe, and connected them to the computer to take a look, this time he was completely dumbfounded, no

Having said it. It's the same as the customer management system, it's all backing up empty data, and the only difference is the old server that runs the financial system

The server hard drive has not been formatted.

If you had formatted both servers and waited to recover your data with a backup hard drive, you would have two cups today

This is also a blessing in misfortune!
