How to crack Wi-Fi password-
Wi-Fi password cracking is the process of discovering the password used to protect a wireless network. These are some techniques used in password cracking:
Techniques of cracking WiFi password-
-
Social engineering – The attacker manipulates a person who knows the password into providing it.
-
Brute-force attacks – The attacker tries several possible passwords in an attempt to guess the password. If the password is a 4-digit number, for example, the attacker would have to try every one of the 10000 combinations. Brute-force attacks usually involve a word-list file. This is a text file containing a list of words taken from a dictionary. A program then tries each word and common combinations. Because brute-force attacks take time, complex passwords take much longer to guess. A few password brute-force tools include Ophcrack, L0phtCrack, THC Hydra, RainbowCrack, and Medusa.
-
Network sniffing – By listening and capturing packets sent on the network, an attacker may be able to discover the password if the password is being sent unencrypted (in plain text). If the password is encrypted, the attacker may still be able to reveal it by using a password cracking tool.
-
Phishing- Phishing is when a malicious party sends a fraudulent email disguised as being from a legitimate, trusted source. The message intent is to trick the recipient into installing malware on their device, or into sharing personal or financial information. An example of phishing is an email forged to look like it was sent by a retail store asking the user to click a link to claim a prize. The link may go to a fake site asking for personal information, or it may install a virus.
-
Spear phishing- Spear phishing is a highly targeted phishing attack. While phishing and spear-phishing both use emails to reach the victims, spear phishing emails are customized to a specific person. The attacker researches the target’s interests before sending the email. For example, an attacker learns the target is interested in cars, and has been looking to buy a specific model of car. The attacker joins the same car discussion forum where the target is a member, forges a car sale offering and sends email to the target. The email contains a link for pictures of the car. When the target clicks on the link, malware is installed on the target’s computer.
