Desperate Hacker

Chapter 234 Members after get off work

Suddenly, there was a knock on the door outside!

Then a woman poked her head in and asked a question in Japanese!

Zhao Changan and Chen Qingfeng were immediately shocked!
Then the two looked at each other in confusion!

Just like this, the two parties looked at each other, and the other party seemed to notice something, and then started to speak English instead!

"I'm sorry, how long do you have? We have reserved this conference room and will come over for the meeting in 5 minutes!"

"Feel sorry!"

Chen Qingfeng said and patted Zhao Changan. The two of them just hugged the computer and put it away, and then hurriedly left the conference room!

When he came out of it, Chen Qingfeng deliberately paid attention to the cameras here!
I came in a bit of a hurry today, in fact I was a bit careless!

But he had already thought of his own way just now!
The network here does not allow external devices to access!

To put it simply, you must have a registered MAC address before you can access it!
However, Chen Qingfeng noticed that many people in the office were using various models of computers!
And everyone’s operating system is different!
There is ubuntu that programmers love most!

Some people also like to use MAC notebooks!
This means that the company is likely to allow employees to bring their own computers to work, because many companies have such an asset-light strategy!

To put it simply, employees use their own computers to work, and the company gives them a certain subsidy every month!

After all, if you use this money to buy a computer, a lot of software and office stuff will have to be reinstalled, which is time-consuming and laborious. Most investors don’t want their investment to be spent on these useless fixed assets. !
Therefore, this gave Chen Qingfeng a chance!
Chen Qingfeng and Zhao Changan returned to the elevator together.

"Did you notice the woman who came in just now?"

"That Japanese woman?"

"Yes! When I came out, I inadvertently scanned her badge! Helpdesk department!"

"HelpDesk?"

"You may have never worked in a foreign company. This is what the operation and maintenance departments of some foreign companies are called! They are responsible for maintaining the company's network, allocating IP addresses, and in short, some chores related to computers are handed over to this department! "

"Then what do we do now?"

"Do you remember what that woman looks like?"

"remember!"

"Our first option now is to hack into her computer!"

"Her computer?"

"Yes! We need her MAC, and then use her MAC address to access this company's network!"

There is one thing that Chen Qingfeng did not explain to Zhao Changan!
That is, the operations department must be responsible for planning the entire company's network planning!
And they will naturally have remote login access rights!

After obtaining their network, it is equivalent to invading the entire company's office network!
Next, Chen Qingfeng only needs to find the computer of the engineer responsible for managing the treasury within the office network!You can open this company and have access to the Bitcoin vault!

Although the founder of the company claims to the outside world that it uses absolutely safe technology that completely isolates the internal and external networks!
But absolute isolation is impossible in today’s world!
It's just that the employee permissions within the company are divided level by level. Chen Qingfeng must find the one who can access the vault!
In a foreign land!Chen Qingfeng and Zhao Changan couldn't understand what the people around them were saying!
But that doesn’t stop them from doing what they have to do!The two of them sat like this from morning to afternoon, from day to night!

When night fell, office workers in a hurry walked out of the office building together!Then they gathered together in twos and threes!
Zhao Changan had a very sharp eye, and around 6:30 in the afternoon, he saw the woman he had met once in the conference room today.

Then he touched Chen Qingfeng.

Chen Qingfeng also noticed the woman after his reminder.

Just like that, the two of them sat up from the chairs on the roadside!Then slowly followed this woman towards the subway!
After getting on the subway, Zhao Changan and Chen Qingfeng stood about ten meters away from her!
The two of them stared at this woman alternately!

After two stops on the subway, the woman got off!

Then the two of them followed out together!

Then they followed this woman to an izakaya!

Maybe this woman is waiting for a friend here!
Not long after, several people met this woman and greeted her warmly!
This is a Chinese restaurant!

Chen Qingfeng looked at the menu and only ordered a salad!
Zhao Changan ordered some Japanese dishes that he had never eaten before!
The two of them were eating like this!Zhao Changan was drinking beer, while Chen Qingfeng turned his head from time to time and looked at the female employee of mx company who was sitting one seat away. She was laughing happily after drinking!

"Don't they say that the Japanese people are in dire straits? Why are they so happy after work and after get off work? What time is it? I remember when I was an intern under you, we were still working overtime at this time!"

"Don't mention this! It's all meaningless overtime! Anyway, if I stay there, I just want to read blogs and stuff!"

"Old Chen, it turns out you are also fishing!"

"Who doesn't fish?"

……

As Chen Qingfeng was talking, his phone suddenly lit up, and then he saw a message from Zhou Yaojie!

It turns out that Zhou Yaojie bought a red-eye flight at night!We can get to Tokyo tonight!

Just party like this and drink until 10:00!The woman slowly said goodbye to her friend, then picked up her bag and left the store!

Zhao Changan and Chen Qingfeng saw this and hurriedly paid the bill!
The two of them were far apart, following the woman, and then passed through the low-rise houses!
Slowly arrived at an apartment!
The balcony of the apartment is connected to the outside!
The two of them were standing downstairs and could see the woman walking up to the third floor of the apartment building!
They memorized the room.

However, he did not go upstairs. Chen Qingfeng walked around the apartment building and soon discovered the network equipment with the NTT logo outside!
Chen Qingfeng turned around and winked at Zhao Changan!

Zhao Changan immediately walked to the alley with understanding and guarded Chen Qingfeng!

Then Chen Qingfeng took out the tools from his bag, inserted the key into the equipment maintenance keyhole, and then opened the equipment box with force!
Immediately afterwards, Chen Qingfeng used various data cables to connect to the device!

It stands to reason that if an apartment like this is connected to the Internet, it must have a transit switch!
Chen Qingfeng checked it and quickly found the room number corresponding to the switch!
Then all he has to do is hack the switch!
Chen Qingfeng connected the serial port cable to the debugging port of the switch!
Then he entered the command to log in to the switch!
Luckily, this is a Cisco device!

Chen Qingfeng tried it, and the Cisco web vulnerability exploited by the Tianqi team was still usable!
It seems that this company has not upgraded and improved safety performance for all customers in a timely manner!

"Okay! Yes!"
