This document summarizes a synopsis on analyzing and preventing pharming attacks on hybrid networks. The objectives are to analyze pharming attacks using Java and prevent users from losing confidential information. Pharming attacks are increasing and are an enhanced version of phishing attacks. The proposed system detects pharming attacks through dual analysis of IP address checks and web page content comparisons. It uses character-level and word-level N-gram algorithms to compare legitimate and fraudulent pages. The system was implemented in Java due to its portability across operating systems. The goal is to avoid attacks from fake sites and prevent information loss.

2. AIM and OBJECTIVE
• The purpose of network security is essentially to prevent loss,
through misuse of data
• There are many attacks which attacks on the nw system.
Basically we are focusing on pharming
attacks
• The main objective of our project is to analyze the attack with
the help of java
• Pharming attacks is analyzed with the help of java

3. The number of pharming attacks are increased now a days and we need to prevent these attacks such
that the user wont loss its own confidential information. The pharming attack is an enhanced version of
phishing attack and it is very important to prevent these pharming attacks. The main idea is to detect
pharming attack using multiple server responses, by performing a dual step analysis composed
• An IP address check of visited domain
• A web page content comparison of a displayed web page against a reference web page:-
In this step we are using two approaches
1. Character Approach-With the help of N-gram algorithm where character wise comparison is done
2. Word Approach-With the help of N-gram algorithm where word to word comparison is done between
legitimate and fraudulent page.

7. TECHNOLOGY USED:-
JAVA
Now-a-days all are familiar with Internet, the worldwide network of computers, which
connects together thousands of computer all over the world. These network
connections are increasing day by day in a rapid rate, so the network traffic is
increasing at a pulse rate. Computers connected to the net are from many different
manufacturers, running on different operating systems and they differ in architecture,
computing power and capacity. By considering this point SUN Microsystems
Corporation felt the need for a new programming language suitable for this
heterogeneous Environment and java was the solution. This breaks barriers between
different computers, chips and operating systems. Using java your application become
compatible with all operating systems.
FEATURES OF JAVA:
• Simple
• Secure
• Portable
• Object oriented
• Robust
• Multithreaded

8. CONCLUSION
To avoid the
attacking of fake
side an preventing
