In fact, Han Feng had already thought of a variety of ways to obtain Huang Zicong's information from Sun Le, such as email, chat software, or mobile phone contact list, etc., of course, it was more complicated, Han Feng could find Sun Le's information from the school, and then according to his family genealogy, he went to the database of the Civil Affairs Bureau to find Sun Le's relatives, and finally found Huang Zicong's home......

Obviously, this method is the most direct and simple, Huang Zicong is online, and Han Feng can directly use technical means to find out his actual IP address.

Now, Huang Zicong and Sun Le are chatting, from the perspective of technicians, that is, they are exchanging data at the moment, and the exchange of data must know the IP addresses of both parties, so that the data packets sent to each other can accurately reach the destination.

This process is not visible and is hidden by the chat software, because these things are useless for users to see, all they care about is the content of the other party's chat, and other trivial things are filtered.

If you want to find out Huang Zicong's IP address, Han Feng also has N methods, but in the final analysis, it is actually to analyze QQ's data packets. Some chat software plug-ins already have their own this function, which can directly display the other party's IP address, but Sun Le's version obviously does not have this function.

Han Feng can use packet capture software to catch the IP packets that are now being exchanged on Sun Le's machine, but this method is too complicated, and Han Feng has an easier way, that is, to directly view Sun Le's firewall.

QQ uses the UDP protocol to transmit information, which is a connectionless protocol, and many firewalls have a UDP snooping function.

The firewall used by Sun Le is the Kingsoft Firewall, which has this function, Han Feng directly turned on his firewall and took a look, and it was very easy to find this UDP connection, on it, Huang Zicong's IP was clearly displayed.

With Huang Zicong's IP, this is easy to do.

Han Feng was about to invade immediately, and when he glanced at it, he saw that the topic they were talking about at the moment was exactly what happened this afternoon.

Feng Liu was dignified: "My dad has warned me very harshly just now, not letting me provoke Han Feng, and asking me to apologize to him." ”

Lele: "No, faint!"

Feng Liu was dignified: "That kid is not small. ”

Lele: "How is that possible?"

Feng Liu was dignified: "I don't know the specifics, you should be careful, don't provoke him for the time being, that kid, it seems that he has practiced, even the police can't get him ......"

…………

Lele: "Cousin, is he really so powerful?"

Feng Liu: "I X, I don't believe it either, but this is what just happened today." ”

Lele: "Then you really want to apologize to him?"

Feng Liu was dignified: "Say a P! Lao Tzu won't go! Damn, sooner or later, I'll find someone to abolish him!"

…………

Han Feng sneered, no longer looked at their nonsense, and easily invaded Huang Zicong's computer, his security configuration was much worse than Sun Le's, in Han Feng's eyes, he was simply a rookie who could successfully invade.

Of course, the difference between a rookie and an old bird is that after a rookie invasion is successful, he may not be able to do anything, and he can't further expand his results, while the old bird, after discovering a vulnerability, will make full use of this vulnerability as a breakthrough and slowly increase his authority until he completely controls the target computer and can do whatever he wants in it.

Han Feng invaded Huang Zicong's computer, in fact, he doesn't know what to do now, he doesn't know what is in Huang Zicong's computer, but it doesn't matter.

Good hackers are all tough intelligence analysts, and they usually have a very meticulous mind and can fully dig into even the smallest intelligence information they find, which is the same as "finding a small vulnerability and then expanding the results".

A hacker who is not good at information intelligence analysis is not a qualified hacker.

Therefore, when a hacker identifies an invasion target, at the beginning, he often does not know how to do it, nor does he know what valuable things are in the target machine, and the way he adopts may be to keep wandering around, constantly scanning, seemingly without any purpose, and often in the end, he can find his own way of intrusion, and then successfully capture the fortress.

Han Feng wanted to deal with the Huang family, but he didn't think about how to give the Huang family a powerful counterattack for the time being. With his current ability, he can only use hacking methods to retaliate.

So, he wanted to hack Huang Zicong's computer, and even the computers of everyone in the Huang family, to find a breakthrough from their computers.

Han Feng began to look through Huang Zicong's computer hard disk according to the user's habit of using the computer to save data.

Han Feng searched almost every corner,Still haven't found anything of interest,Judging from the things in this computer,It should be a big possibility that this computer is a new computer,Its configuration is a grade higher than Han Feng's mainstream configuration,And the system disk is still very clean,There are not many redundant things,Although the other disks are huge,But there are few types,In addition to games,It's a movie,Of course,More or moreAV。 Han Feng even took care of the hidden documents, and it turned out that Huang Zicong didn't seem to have the consciousness to hide things.

It seemed that there was nothing useful on the hard drive, so Han Feng focused his attention on the Internet, and he began to check Huang Zicong's Internet records.

There are a lot of Internet records in the browser, and Han Feng flips through the past one by one, search engines, school forums, game websites, and online photo albums......

Kindness?

Han Feng swept all the way, and suddenly felt that there was something strange, so he looked at it again from the beginning, and he found that it seemed that Huang Zicong had a soft spot for an online album and had to log in to this album almost every day.

This rather peculiar phenomenon made Han Feng feel a little strange, opened the album and took a look, but found that a password was needed, and Han Feng also found an abnormal phenomenon, Huang Zicong usually remembers the password on other websites, but this online album does not remember the password.

There are quirks!

This anomaly aroused Han Feng's interest, and although an album could not seem to contain any useful information, he decided to crack the album with a keen sense of smell in his profession.

The username of the album is displayed on the path above, called "fengliu99", so Han Feng only needs to get the password.

How do I get the password?

Han Feng started with those memorized passwords, and it can be seen from those asterisks that his passwords are almost all 8-digit.

Since some websites remember passwords, that's easy. Han Feng has a small tool whose function is to display those remembered asterisk passwords in plain text.

According to hacker psychology, the vast majority of people use the same password for all accounts, and only a very small number of people will have the necessary security awareness and use passwords with different security levels according to the different security levels of the accounts.

Using the display asterisk password tool, Han Feng got the password "19910725".

Seeing this password, Han Feng despised Huang Zicong in his heart, and he didn't have to think about it, this password must be Huang Zicong's birth date, and his security awareness is really low.

At this time, Huang Zicong and Sun Le had also finished chatting, he seemed to have something temporary, and turned off his computer directly, and Han Feng and his computer were disconnected.

But it doesn't matter, anyway, Han Feng has already got what he wants, and he can also upload the online album directly from elsewhere.

used the proxy to go to the network album, filled in the username and password, and confirmed, but the result made Han Feng slightly stunned, because it showed "wrong password".

This online album even uses another password!

Han Feng became more and more interested in this album.
