How to Hack WiFi

How to Hack WiFi Passwords

WiFi networks rely on several common wireless security standards to prevent unauthorized access. The most common wireless security standards are:

• WEP: Introduced as part of the original 802.11 standard ratified in 1997, WEP (Wired Equivalent Privacy) is a deprecated security algorithm for wireless networks. It uses the stream cipher RC4 for confidentiality and the CRC-32 checksum for integrity. In 2001, a group of security researchers published a method on how to exploit the way the RC4 cipher is used in WEP. The exploit makes it possible to hack virtually any WEP network within a few minutes using readily available software programs and standard networking equipment. It’s safe to say that even children can learn how to hack into a WiFi protected by WEP with minimal effort.


• WPA: Naturally, a safer wireless security standard had to replace WEP, and, in 2003, WPA (Wi-Fi Protected Access) became that standard. To prevent the types of attacks that compromised WEP, WPA relies on the Temporal Key Integrity Protocol (TKIP), employing a per-packet key that is dynamically generated for each packet. It also includes something called a Message Integrity Check to prevent an attacker from altering and resending data packets.


• WPA2: Eventually, WPA was replaced by WPA2, which implements all mandatory elements of the IEEE 802.11i standard, including support for CCMP and an AES-based encryption mode. While it’s very much possible to learn how to hack someone’s WiFi even when it uses WPA2, such attacks require a degree of sophistication that makes them unfeasible for most cybercriminals.

Naturally, cybercriminals prioritize weaker targets over those that rely on more modern security standards.

Launch NetSpot.
Enter Inspector mode.
Locate your WiFi network from the list of available WiFi networks.
Look at the Security column and see if it says “WPA2.”
If it does, your WiFi network meets the basic prerequisite for security.

Find out your router’s IP address.
Log in to the router’s admin interface.
Look for WiFi security settings.
Select WPA2 as your prefer wireless security standard.
Save the settings and possibly restart your router.

Every time you change your router’s security settings, use NetSpot’s Inspector mode to verify that the settings have really been applied. Besides using WPA2 as your preferred wireless security standard, you also need to choose a strong WiFi password to prevent WiFi password hacks. These are some characteristics of a strong password:

• The password is at least 12 characters long.


• The password uses a combination of letters, numbers, and special characters.


• The password is not commonly used (12345ASFD).


• The password is completely nonsensical.


• The password contains no personal information (birthdate, maiden name, and so on)


• The password is unique and not used anywhere else.


• The password is not written on a piece of paper or saved by the browser.


• The password is not shared with anyone.
