- Keystroke logging: it is tool that is designed by the hackers to keep a record of the keystroke on the computer system or any machine to get access to any confidential file later. While some crack the information, other hackers run this program for security reasons to test the security system.
- Phishing: it is the most dangerous type of web attack where the user blindly trusts another site which looks exactly like the original and passes his personal details and confidential data such as passwords and gets trapped therein.
Social engineering: This tactic is usually used by the hackers who are super intelligent and want to gain access to a particular network or site. They pretend to be a user who cannot gain access to his account and approach system administrator to get the information.
