Over the weekend, more than 22,000 hackers from around the world gathered at DEF CON, the annual hacker event.

Surprisingly, this time there were also several robotic hackers who were present at the same time. In the ensuing man-machine hacking match, although the robots failed to get the first, they still defeated several top hacking teams.

Could it be said that the era of robots as hackers has come?

This robotic hacker who fights against human hackers is Mayhem who won the Cyber ​​Grand Challenge (CGC).

Mayhem, who had “fighted” all the robots, came to the CTF (capture contest) battlefield and started a 60-hour (two-and-a-half days) “blood battle” with 14 human hacking teams. But the result was not necessarily the same as what he thought. ".

After all, what it has to follow is the “rules of the game” set by humans.

The "rules of the game" of man-machine competition

In this CTF man-machine battle, the organizers provided a customized environment - a server and a computer system with special loopholes (unlike the Windows or Mac systems on the market, etc.), and 15 teams had to take advantage of offensive and defensive methods. Other people's "flags" get points.

Specifically, the tasks of each team include two aspects:

Find out the vulnerabilities on your server and patch it as soon as possible so as to prevent attacks from the other side.

When other teams haven't patched the loopholes, they attack them and win their "flags."

During the offensive and defensive process, each team will score points on the basis of the basic points, and lose points if they lose the flag.

In simple terms, if the base score of each team is divided into 10,000 points, when you find a hole in the other side and successfully get his “flag”, you can get 1000 points for this question, and at the moment your points The value is 11,000 points and the other party becomes 9000 points. (Note: The scores for each question type are different. Here is a simplified explanation.)

By analogy, in the process of mixed fights among 15 teams, only when your offensive and defensive methods are stronger than those of other teams can you continue to get someone else's "flags" and prevent others from getting your own "flags."

There will be many different types of questions in the game, such as reverse analysis, encryption and decryption and other security attack and defense topics, so the test is the ability of the entire team in various branches of technology.

Therefore, there are extremely high requirements for the security technology capabilities and collaboration capabilities of human hacking teams.

In general, each member of each human team has its own areas of expertise. Team members must work together like a "special warfare team" to play games.

How do robot hackers compete with human hackers?

Although robotic hackers who follow the CTF rules of competition use “attack and defense” methods to “capture the flag” points, “combat” methods are different from human hackers.

The robot hacking program runs automatically, finds loopholes and patches itself, and the team that created the robot hacking program only needs to sit side by side to watch the game.

The robotic hackers who played this time all depended on their own "ability", because all network programs in the game, the bugs in the code are organizer-specific, it is mainly through the preset application to analyze and respond to discovered code loopholes. , And by offensive and defensive means to "capture the flag."

The era of robotic hackers: The time has not yet arrived, but the prospects are considerable

Obviously, the robot hackers themselves have not arrived yet, and they are thrown off to 13 at a time when they are battling with 14 human hacking teams. It is undeniable that there is a certain gap between robotic hackers and human hackers.

However, don't forget that it still beats two top human hacking teams. In other words, it defeated two of the 14 most intelligent team representatives.

This time, the b1o0p team consisting of Tencent-0ops and blue-lotus won the second place in the DEF CON finals, creating the best record in history. Tencent also sent three members of its Cohen Lab to participate.

For this reason, Ai Fanji interviewed Mr. Lu Yiping, director of the Keen Lab of Tencent. He said that in the field of information security, technical analysis is a very complicated process, and it is not easy to simulate or implement it entirely through the machine.

However, this CTF also initially proved that robotic hackers can intelligently and automatically conduct information security protection, and made some technical prototypes. With the development of AI deep learning technology, information security technology combined with AI artificial intelligence is also the future development direction.

At present, in this field, information security protection by robots is still an experimental stage. It has not yet been able to call it a mature technology, or to commercialize it. Relatively speaking, it is still at the initial stage of this technological capability and will always develop and progress.
