How to crack WiFi stealth? Revealing the truth about hidden networks and preventive measures
In recent years, with the improvement of network security awareness, more and more users choose to set WiFi to "invisible" (that is, hide the SSID), thinking that this can avoid being discovered or attacked by others. However, is hidden WiFi really safe? This article will combine hot topics and data from the entire Internet in the past 10 days to analyze the WiFi stealth cracking methods, potential risks, and preventive measures for you.
1. Inventory of recent popular network security topics
| topic | heat index | Main discussion content |
|---|---|---|
| WiFi Stealth Security Controversy | 85% | Does hiding the SSID really prevent hackers? |
| WiFi password cracking tool | 72% | The use and prevention of Kali Linux and other tools |
| Public WiFi Risks | 68% | Potential threats from hidden networks in public places |
2. How WiFi Stealth Works
The principle of hiding WiFi (that is, not broadcasting the SSID) is to stop sending network name information to surrounding devices through the router. Normal devices cannot see the network directly when scanning for WiFi, but users can connect by manually entering the SSID and password. Many people mistakenly believe that this method can effectively prevent hacker attacks, but in fact there are obvious security loopholes in hiding the SSID.
3. Common methods to crack hidden WiFi
| method | Tools/Techniques | success rate |
|---|---|---|
| passive sniffing | Wireshark, Airodump-ng | 60%-80% |
| Active detection | Kismet, MDK3 | 70%-90% |
| dictionary attack | Hashcat, John the Ripper | Depends on password strength |
4. Why is it not safe to hide the SSID?
1.Active detection of the device will expose the SSID: When a connected device tries to reconnect to the network, it will automatically send a request packet containing the SSID, which hackers can obtain through packet capture tools.
2.No defense against professional tools: For example, Airodump-ng in Kali Linux can directly scan hidden networks, while MDK3 can force the client to send a connection request.
3.May reduce user experience: Hiding the SSID will cause the device to frequently search the network, increase power consumption, and require manual input of information for each connection.
5. Really effective WiFi security measures
1.Use WPA3 encryption: The latest encryption protocol can effectively defend against dictionary attacks and KRACK vulnerabilities.
2.Set strong passwords: It is recommended to be more than 12 characters, including uppercase and lowercase letters, numbers and special symbols.
3.Enable MAC address filtering: Allow only known devices to connect (but MAC addresses can be forged).
4.Turn off WPS function: WPS PIN codes are easily cracked by brute force.
5.Update firmware regularly: Patches known vulnerabilities in the router.
6. Legal and ethical reminders
It is illegal to hack other people's WiFi without authorization. This article is only a technical discussion. According to Article 27 of the Cybersecurity Law, no individual or organization may engage in activities that endanger network security, such as illegal intrusion into other people’s networks.
Summary:Hiding WiFi SSID can only protect against "gentlemen" but not "hackers". Real security requires a combination of encryption protocols, strong passwords and network behavior management. It is recommended that users regularly check router security settings to avoid becoming the target of cyberattacks.
