Social Engineering:
This Process is defined as Hack the human mind without any tools...
This has become one of the hottest topics today and it seems towork out most of the times. Social Engineering doesn’t deal with the network security issues, vulnerabilities, exploits, etc. It just deals with simple Psychological tricks that help to get the information wewant.
This really works!! But it requires a lot of patience.
We are all talking about network security and fixing the vulnerabilities in networks.
 But what happens if some internal person of a network accidentally gives out the passwords. After all we are all humans; we are also vulnerable and can be easily
 exploited and compromised than the computers.
Social Engineering attacks have become most common during the chatsessions.
With the increase in use of Instant Messengers, any anonymous person may have a
chat with another any where in the world. The most crucial part of this attack is to
win the trust ofthe victim.
Phishing Attack:
The act of sending an e-mail to a userfalsely claiming to be an established legitimate enterprise in an attempt to scam the user into surroundering private information that will be used for identity theft. The e-mail directs the userto visit a Web site where theyare asked to update personal information, such as passwords andcredit card, social security, and bank account numbers, that the legitimate organization already has. The Web site, however, is bogus and set up only to stealthe user’s information.
Cookie Hijacking:
In cookie hijacking we can hack email accounts very easily.. This trick is very
 dangereous because whenever user change a password thenthere is no need to
 attacker for again hack Email- ID of victim. And it would take youto inbox of victim's yahoo account without askingfor any password of victim account.
Keyloggers:
Keylogger is a software program or hardware device that is used to monitor and log
each of the keys a user types into a computer keyboard. The user who installed the program or hardware device can thenview all keys typed in by thatuser. Because
these programs and hardware devices monitor the keys typed in a user can easily
find user passwords andother information a user may not wish others to know about.
Keyloggers, as a surveillance tool, are often used by employers to ensure employees
 use work computers for business purposes only. Unfortunately, keyloggers can also
 be embedded in spyware allowing your information to be transmitted to an unknownthird party.
