Wi-Fi Security: How Easy Is Crack Wi-Fi?

This updated guide examines Wi-Fi Security: How Easy Is Crack Wi-Fi? and organizes the essential facts, background, and practical takeaways in clear American English.

Use a very long password and combine multiple characters or set to hide the username. But really, how can these ways of securing WiFi?

Hide the network SSID

There is a very common mistake that WiFi's anonymity will protect the network from being attacked. In fact, any WiFi scanning tool will display your network, except that it will not display the SSID, and other information will be visible. So it only makes it harder for friends and relatives to discover your network.

Instead of using the default WiFi setting, the device must find a way to connect itself. This is not only inconvenient but also leads to many problems. Some of them cannot use the hidden network, so the advice is not to use SSID hiding because the only person in trouble is you.

WEP password

When WiFi security settings will have some options. Wired Equivalent Privacy (WEP) is the oldest standard and is often thought of as using it and not using passwords. WEP is replaced with more advanced WPA2 (but not perfect yet). In 2011, hacked WiFi WEP is extremely simple.

Previously, there was an old device that was not compatible with WPA2 but now most of them use the new standard. Many routers still have WEP options but it's best not to use them, remember to avoid public WiFi using WEP. You will easily lose your password and much important information, even when using a VPN.

WPA and WPS

Perhaps you think the WPA2-PSK 25-character password is the safest. It may be true, but it does not mean absolute safety. To simplify the connection process, many routers will use WPS. WiFi Protected Setup (WPS) will replace long passwords with 8-digit strings.

To use WiFi safely is not as easy as you think

The router manufacturer also knows that it is not safe to give 60 seconds of rest after 3 wrong entries. To randomly type the 8-digit password will take 6.3 years. But by dividing each string into 4 characters, now less than 1 day has broken WiFi.

If you use the right tool, breaking the WPA2 WiFi password will take less than a few hours. Since WPS is standard for all routers and is turned on by default, you should turn it off and remember to check again because some loose WPS batteries cannot be turned off.

How safe is WiFi?

In fact, no matter how cautious, there is still the possibility of a WiFi network being hacked. Just having enough time and patience is difficult for hackers to find a way. There is only a way to turn off WiFi but in this era it seems a bit difficult. So the only way is to remember to always update your device with the latest firmware.
