Where are you? : Hackers are here. Where are you? The explosive growth of the Internet has brought many good things…As with most technological advances, there is also a dark side: criminal hackers. The term “hacker” has a dual usage in the computer industry today. Originally, the term was defined as: HACKER noun. 1. A person who enjoys learning the details of computer systems and how to stretch their capabilities…. 2. One who programs enthusiastically or who enjoys programming rather than just theorizing about programming HISTORY : HISTORY 1960s: The Dawn of HackingOriginal meaning of the word "hack" started at MIT; meant elegant, witty or inspired way of doing almost anything; hacks were programming shortcuts 1986: Congress passes Computer Fraud and Abuse Act; crime to break into computer systems. Kevin Mitnick convicted; first person convicted under law against gaining access to interstate network for criminal purposes. WHY TO KNOW HACKING….? : WHY TO KNOW HACKING….? SECURITY TESTING CONSUMER ADVOCACY CIVIL RIGHTS MILITARY INTERESTS HACTIVIST POLITICS FOLLOWING ARE THE WEAK POINTS OF NETWORK : FOLLOWING ARE THE WEAK POINTS OF NETWORK Client –site security doesn’t work Malicious code cannot be hundred percent protected against Firewalls cannot protect you 100% from attack Any intrusion detection system (IDS) can be evaded FOLLOWING ARE THE WEAK POINTS OF NETWORK : FOLLOWING ARE THE WEAK POINTS OF NETWORK Secret cryptographic algorithms are not secure Passwords cannot be securely stored in the client unless there is another password to protect them Security through obscurity does not work You cannot securely exchange encryption keys without a shared piece of information SOME TYPES OF HACKING : SOME TYPES OF HACKING By Sending spywares By SQL injections By Application hacking By Cookie stealing By USB theft By sending mail bomb SPYWARES : SPYWARES Spyware is a type of malware that is installed on computers and collects little bits of information at a time about users without their knowledge. The presence of spyware is typically hidden from the user It sends information to the hacker secretly Hacking Through Trojans and Backdoors : Hacking Through Trojans and Backdoors SPYWARE-KEYLOGGER : SPYWARE-KEYLOGGER SQL INJECTIONS : SQL INJECTIONS SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of SQL Server for parsing and execution. Any procedure that constructs SQL statements should be reviewed for injection vulnerabilities because SQL Server will execute all syntactically valid queries that it receives. SQL INJECTIONS : SQL INJECTIONS The user is prompted to enter the name of a city. If user enters Redmond, SELECT * FROM OrdersTable WHERE ShipCity = 'Redmond' Redmond'; drop table OrdersTable-- In this case, the following query is assembled by the script: SELECT * FROM OrdersTable WHERE ShipCity = 'Redmond';drop table OrdersTable--' APPLICATION HACKING : APPLICATION HACKING Application hackers break security on application software in order to get it for free. One way they gain access to software that requires a serial number for installation is by setting up a serial number generator that will try millions of different combinations until a match is found APPLICATION HACKING : APPLICATION HACKING COOKIE STEALING : COOKIE STEALING This is the now a days hackers mostly using hacker sends a suspicious java script to victim asking him to place it in the address bar and hit “ENTER” so that he may see some miracle If the victim follows that his current browsers cookies will be sent to the hacker Then the hacker replaces his cookies with the victim’s cookies THEFTING PASSWORDS THROUGH USB : THEFTING PASSWORDS THROUGH USB The hacker secretly places a USB theft software in data travelers whenever it is connected to the computer it captures the passwords of that system Hence the hacker gains the access to the victims network MAILBOMBS : MAILBOMBS A mail bomb is the sending of a massive amount of e-mail to a specific person or system. A huge amount of mail may simply fill up the recipient's disk space on the server or, in some cases, may be too much for a server to handle and may cause the server to stop functioning. What is Ethical Hacking? : What is Ethical Hacking? Ethical hacking – defined “methodology adopted by ethical hackers to discover the vulnerabilities existing in information systems’ operating environments.” With the growth of the Internet, computer security has become a major concern for businesses and governments. In their search for a way to approach the problem, organizations came to realize that one of the best ways to evaluate the intruder threat to their interests would be to have independent computer security professionals attempt to break into their computer systems. Hacker classes : Hacker classes Black hats – highly skilled, malicious, destructive “crackers” White hats – skills used for defensive security analysts Gray hats – offensively and defensively; will hack for different reasons, depends on situation. → CONCLUSION : → CONCLUSION THE ONLY WAY TO STOP A HACKER IS TO THINK LIKE HACKER CONCLUSION : CONCLUSION KNOW HACKING BUT NO HACKING….!
