Can ordinary people use hacking software to easily crack Wi-Fi passwords? Ye gong from the School of Computer Science and Technology of Fudan University told this reporter that, first of all, if the other party is an ordinary person who does not know much about computer expertise, even if the above-mentioned password cracking software exists, it is also difficult to perform operations. If the other party has been educated about the relevant knowledge, it is feasible to crack the Wireless Router password through tools; not to mention hackers.
Expert: Hard to prevent hackers
Ye said that it is possible for hackers to obtain accounts through routers. "As far as the circle I have reached, people with such technologies are not interested in the information of ordinary people. As mentioned in the article, you cannot be hacked, it's just that you are not blacklisted. However, if there are people like that, it is hard to prevent them, but these people are already at the top of the pyramid ."
Liang Gong, a well-known security software engineer in China, told this reporter yesterday that cracking the Wi-Fi password is not as easy as the story says. "If the common encryption method is wpa, if the password is relatively simple, that is, pure numbers or words, it is easier to crack. However, if the password is complex, for example, it takes a long time for a hacker to crack the password, and it may take several days to crack the password based on the complexity of the password."
The network password should not be too simple
The key step mentioned in the story is to first access the Wi-Fi network. As long as the hacker enters the same LAN, the subsequent work of the hacker will be simple. According to the story, even if a hacker does not crack the administrator password of A vro, he can pretend to be a gateway. In this way, there are many clients in the LAN that access the internet, it can be captured. However, if it is an https webpage, the webpage hacker cannot see the actual content due to the password.
Liang told reporters about the security measures for using vrouters in the family that it is better to set the Wi-Fi password and administrator username and password of the vro to be more complex. In addition to the hacker's security suggestions in the story, you can set the IP address restriction function on the vro, such as setting the access duration and the number of times of an unknown IP address, which can shorten the connection time of the hacker, it makes it more difficult for hackers to crack passwords.
Hacker defense measures
As a white-haired user, the more you do the following, the more secure you are:
1. the router connection password is a little more complex. For example, testak47521test is much better than ak47521.
2. Change the account and password of the vro management backend. 90% of the lazy people are still in admin and admin.
3. Do not tell untrusted people your Wi-Fi password.
4. Do not use ROOT for jailbreak on mobile devices. The device after ROOT/jailbreak is equal to the one on the bus.
5. log on to the vro management background to see if any devices you don't know are connected to WiFi. If yes, disconnect and disable the Mac address. Change the Wi-Fi password and vro background account password immediately after sealing.
